Description

A DISPENSER FOR CONTINUOUS ROLLED PAPER MESH AND A PAPER PRODUCT FOR USE IN SUCH DISPENSER TECHNICAL FIELD The invention relates to a space saving and compact dispenser for rolled continuous paper web where the dispenser is adapted for a compressed or deformed paper product, as well as a paper product to be used in said dispenser.

TECHNICAL BACKGROUND Paper dispensing devices that dispense paper from the center of a roll of spiral core paper or cracked, coreless paper are known as central flow or central feed dispensers. The continuous paper web in said dispensers is fed from the axial or centered portion of the paper roll. A normal rolled paper product for this purpose could have a cylindrical shape with a substantially uniform diameter. Paper dispensers of this type have a general cylindrical shape substantially conforming the rolled paper products that will be dispensed, both with Regarding the shape and size, or sizes if several types of rolls are adapted. Prior art central flow feed dispensers as shown in US 5 370 338 and US 4 524 895 provide arrangements for paper roll dispensers mounted to the wall. As can be seen from both documents, a dispenser of this type has a cross section that is largely decided by the diameter of the paper roll. When mounted on a wall, the normal dispensers will extend even further from the wall corresponding to the outer diameter of the dispenser box plus the space occupied by the connecting means at the rear of the dispenser. The size of the dispenser box depends on the size of the roll to be adapted and the empty space due to the manufacturing tolerances of the production of said roll. Therefore, the size of the paper roll is a major limiting factor when it comes to reducing the corresponding size of the dispenser. In addition, the known dispensers are also adapted to said central flow coiled paper with no core, normal, or cylindrically shaped mesh product with a substantially uniform diameter. Due to factors such as hardness and roll density of continuous flow wound core paper, it has not been practical manufacturing and transporting said rolled paper web in a deformed or compressed state. First, the rolled paper web could have to be configured to assume a cylindrical shape before loading it into a dispenser. This could present a problem for the user due to said hardness of the product. Second, due to the need to keep the continuous paper web wound in a substantially cylindrical shape, due to the cylindrical shape of the corresponding dispensers, it has not been possible to transport and / or use said web of rolled paper in a deformed or compressed. The compression of some types of winding rolls of continuous paper web, such as rolls of toilet paper, is known. For transport purposes, but these products are not intended to be central flow dispensers. Products of this type are dispensed in place by unwinding or dispensing the mesh from the outer periphery of the woven continuous paper mesh roll, also called "peripheral feed". For this reason, such rolls will often be modulated or manually reconfigured to restore a substantially cylindrical shape to fit the existing dispensers. A problem solved by the dispenser according to the invention is to provide a space-saving dispenser and compact for rolled central flow or central feed paper products, wherein the dispenser is adapted to said paper product. A further problem solved by the invention is to provide central flow or core feed continuous paper web allowing space savings substantially when packing and transporting assembled packages or pallets containing said paper products.

DESCRIPTION OF THE INVENTION It is therefore an object of the present invention to provide a space-saving and compact dispenser for central flow wound paper web where the dispenser fits a compressed or deformed paper product, as well as a paper product to be used. in said dispenser. The above problems are solved by a central flow paper dispenser according to claim 1 and a paper product according to claim 8. In the following text, the general term "paper roll" is intended to cover all types of spiral or cracked core woven product, without central flow core, comprising continuous paper mesh, non-woven fibers and other materials suitable for dispensing from a central flow dispenser. The term "central axis" is used to indicate a longitudinal axis through the central section of said roll. According to a first embodiment the invention relates to a central flow paper roll dispenser, said dispenser has a housing comprising a first section for connecting the dispenser to a support surface and a second section enclosing at least partially a radial circumference of a roll of non-cylindrical central flow paper. This first embodiment is primarily intended for dispensers mounted to contain a paper roll with its central axis in a substantially horizontal position. Said dispenser can be mounted on a surface located at virtually any angle and allows the paper to be fed from either end of the open dispenser. The feed direction is determined by which the end of the rolls is pre-initiated and the orientation of the roll in the dispenser. Starting previously with a roll of paper before placing it in a dispenser is a common practice for rolls with central feed. Once a desired length of paper has been dispensed from the paper roll, the paper can be manually chopped or pulled on an edge provided for this purpose. Said edge can be located in a position adequate along any or outer edges of the second section. The edge or edges may be in the shape of a saw or other shape to facilitate breaking the paper. A second preferred embodiment further comprises a third section enclosing a first end of the paper roll and preferably, but not necessarily, a fourth section enclosing at least a second end of the paper roll and an exit port in connection with said third. and / or fourth section for dispensing paper from the paper roll. In the following embodiments, it will be assumed that the exit port is located in the third section as long as the dispenser comprises a third or fourth section and no alternatives are given. Once a desired length of paper has been dispensed from the paper roll, the paper can be cut manually and pulled over an edge provided for this purpose. The edge or edges may be a part of, or surround the exit port and may be sawn or otherwise configured to facilitate paper cutting. Two or more of the previous sections can also be made in one piece. A cross section through the dispenser taken perpendicular to a central axis through a hole in the paper roll has a major axis and a minor axis, wherein the major axis is substantially parallel to the support surface for the dispenser.

In this text, the term "connected" can be interpreted as including either fixedly or removably connected. In addition, the term "removably connected" can be interpreted as being completely removable and hinged. According to an alternative, a horizontally placed roll can be mounted on a substantially horizontal surface, such as under a cupboard or a similar unit. According to an additional alternative, a horizontally placed roll may also be mounted on a substantially vertical surface, such as a wall. In these cases, dispensing is achieved by pulling the side portions of the continuous paper mesh out of either end, and straight out of a dispenser mounted on the vertical or horizontal surface. Dispensers according to the first embodiment are preferred for this type of arrangement, so that a roll of paper as a rule will not require support of a lower end surface and may allow it to be dispensed from either end. However, dispensers according to the second preferred embodiment can also be used for rolls placed horizontally. According to a further alternative, a dispenser can be located with the central axis of the central flow coil placed substantially vertical in a wall or similar. Said wall preferably, but not necessarily, is vertical or almost vertical. A vertically placed roll can normally be dispensed in a vertical downward direction, although a modality adapted to dispense vertically upwards is also possible. The dispensers according to the second preferred embodiment are suitable for this type of arrangement, since as a rule, a roll of paper will require support of a lower end surface. In order to refill a dispenser, one or more sections of the dispenser may be more or less removable or operable. According to a first alternative of the first embodiment, the second front section of a substantially horizontally mounted dispenser is connected to the first section along its lower longitudinal edge. The second section can be curved outwards and upwards, to form a substantially oval dispenser, leaving a substantially parallel space between its upper longitudinal edge and the first section. Depending on the size of the space, a roll of paper may be inserted from either end of the dispenser, or down through said space, allowing at least a portion of the second section to resiliently deform away from the first section during the dispenser charge. Said dispenser, for example, can be made in one piece, by stamping and folding a target made of sheet metal metal. According to a first alternative of the second embodiment, a horizontally placed roll can be mounted on a horizontal surface, such as underneath a cupboard or a similar unit. In this case, dispensing is achieved by pulling the sides of the continuous paper mesh out of either end or straight out of a dispenser mounted on said horizontal surface. This dispenser may have a housing comprising a first section connecting the dispenser to a support surface, a second section enclosing at least partially a radial circumference of a non-cylindrical central flow paper roll, a third section enclosing an end of the paper, a fourth section enclosing an opposite end of the paper roll and an exit port in connection with the third or fourth sections for dispensing paper from said paper roll. When mounted on a horizontal surface, the second section could look down. Suitable aperture arrangements could include any of the third or fourth end sections or a horizontally extending end section on the side of the second section facing the user.

According to a second alternative of the second embodiment, a vertically placed roll can be mounted on a substantially vertical surface, such as a wall or the like. When mounted, for example on a vertical surface, the second section can be located on the front of the dispenser, facing the user. Similar to the first alternative embodiment, the opening arrangements may include any of the third or fourth end sections, disposed as removably-removable sections, or integrated with at least a portion of the second vertically extending section. According to a third alternative of the second embodiment, the second front section is removably connected to the first section to allow loading of the paper roll. This can be achieved by arranging a front portion or one or more side portions or a combination thereof, being part of the second section, to be removable from the dispenser. Alternatively, the second front section and / or at least part of the upper section section may be hinged vertically or horizontally relative to one another of its adjacent sections. The second section can be hinged to the side using a vertically extending hinge, said hinge can be placed on or adjacent to a line where the second section is joined to the first section. The second section may further comprise two halves, wherein each half section is hinged to one side using a hinge that extends vertically adjacent a line where the respective halves of the second section are joined to the first section. The two halves can be joined at the front of the dispenser, where their equalizing edges can be joined along a line in a vertical, angled, irregular or otherwise configured configuration. According to a fourth alternative of the second modality, a unit can be joined to the first section by a horizontal hinge. Said unit may comprise the second front section and the fourth upper section, with a hinge placed on, or adjacent to a location where the second front section is attached to the third lower section. The unit may also comprise the second front section and the third lower section, with a hinge placed on or adjacent to a location where the second front section is joined to the fourth upper section. A unit may further comprise the second, third and fourth section, with a hinge positioned where the fourth upper section is attached to an upper part of the wall mounted in the first section. According to a fifth alternative of the second embodiment, a unit comprising the second frontal section and the fourth upper section may join removably at least said third lower section to allow loading of the paper roll. In this case. The second section circulates the paper roll and is supported by the third section around its lower periphery. According to a sixth alternative of the second embodiment, a unit comprising the second front section, the third lower section and the fourth upper section can be removably connected to the first section to allow loading of the paper roll. This can be achieved by using one or more closing means, which are actuated to release said unit. Alternatively, the front surface of the first section may be provided with at least one guiding means, such as a simple or parallel assembly or a similar profile arrangement. This allows the user to slide the unit horizontally or vertically in relation to the first section and in the plane of said section, from a dispensing position to a position where the unit is removed from the first section in order to refill it. In the above alternatives of the second embodiment, the third section may be arranged to enclose a lower portion of the paper roll, they may be arranged to support and hold the weight of the paper roll. Also, the exit port to dispense paper from said roll of paper may be arranged in said third section. The exit port for dispensing paper from the paper roll may alternatively be arranged in an adjacent fifth section from and below the third section. The fifth section can be fixed to the third section or it can be removable and replaceable to allow the exit port that will be changed or adapted to provide means to cut different qualities of paper or continuous paper mesh. The dispenser may have a substantially oval, elliptical or rectangular cross section, or any intermediate combination of these shapes in cross section. This applies to the case where the second section by itself circulates the paper roll, so that its cross section is substantially symmetric around the major and minor axes. This applies to the case where a front external part of the second section between the points on either side of the dispenser where the second section joins the first section, which is mounted on a support wall. In the latter case, the external part of the second section may have, for example, a generally elliptical middle shape which is attached to the first section having a rectangular shape connected to the wall. Said dispenser could be symmetric around the minor axis only. However, design considerations and Manufacturing may require the outer edges of the second sections, substantially coinciding with the main axis of the cross section of the dispenser, to be extended more or less directly into the first section adjacent to the supporting wall. The ratio of the major axis to the minor axis preferably, but not necessarily, may be on the scale of 1.1: 1 to 2: 1. The ratio may also depend on the diameter and / or thickness of the paper roll and the density of the paper roll of the rolled paper mesh. The invention also relates to a roll of central feeding paper for use in a dispenser as described above. The paper roll can be compressed into a non-cylindrical shape wherein a cross section taken perpendicular to a central axis through a central hole in the paper roll has a major axis and a minor axis, wherein the major axis is substantially parallel to a support surface for the dispenser. The ratio for the major axis on the minor axis for said roll can be chosen in the previous scale. According to a preferred embodiment, the woven paper mesh roll is permanently compressed into an elliptical, rectangular or similar cross section, which allows it to be placed in a dispenser according to the invention. This is the case for relatively paper rolls large and / or rolls of paper with a very large hardness to allow a user to deform the roll manually. A paper or roll of continuous paper towel of this type can have a roll density in the range of 0.2-0.3 g / cm3 and is compressed to a predetermined shape during roll manufacture. These rolls of paper can be without core or have a cracked removable core. According to a further embodiment, the woven paper towel roll is at least temporarily compressed into an elliptical, rectangular section or the like, which allows it to be placed in a dispenser according to the invention. A woven paper or roll of continuous paper mesh of this type can have a roll density less than about 0.2 g / cm3, but not less than 0.1 g / cm3. This allows the compression of the roll or rolls before the transport packaging, as well as manual compression of the roll before being loaded in the dispenser. Paper rolls of this type can be used for paper grades with higher compression, relatively smooth, or rolls of paper relatively loose windings. This type of rolls can be retained in compression during transport and storage and can be expanded at least partially to its original cylindrical shape when removed from the package. Said compressed or deformed woven paper towel product made of paper, non-woven fiber or similar, may have a substantially elliptical or rectangular cross section having more and less different major and minor axes in cross section, as opposed to a rolled paper web product with normal central flow having a substantially uniform diameter. The central orifice of said paper roll can conform to the external oval, elliptical or rectangular shape of the roll or be allowed to collapse completely or at least partially. The ratio of the major axis to the minor axis can be up to approximately 2: 1. As stated above, this ratio, preferably, but not necessarily, is in the range of 1.1: 1 to 2: 1, depending on the diameter and / or thickness of the paper roll and the roll density of the rolled paper web . A non-unwrapped continuous paper web product compressed or deformed according to the invention will allow a larger number of products to be packaged in a standard size pallet. For the parquet, one modality uses a ratio on the scale of 3: 2 to 5: 3. For example, a standard-sized pallet measuring 400x600 mm will take 4 rolls of a compressed A-Tor ® with a diameter (0) of 300 mm to 300x200 mm. These rolls could normally require a pallet of 600 x 600 mm. Similarly, the 400 x 600 mm pallet will take 10 rolls of M-Tork® rolls from 0 to 200 mm to 200 x 120 mm, instead of 6 uncompressed rolls.

Finally, the 400 x 600 mm pallet will take 16 rolls of mini-Tork® rolls from 0 to 150 mm to 150 x 100 mm. These rolls could normally require a pallet of 600 x 600 mm. A further embodiment relates to a method for forming a continuous paper web product wound to the central flow for use in a dispenser according to the invention. Each of said rolled paper web products comprises a length of woven material in a cylindrical expandable mandrel, which is removed to produce a coreless roll. Said roll may be somewhat resilient in a substantially radial direction. According to the method, the rolls are arranged in a predetermined arrangement having at least one layer of adjacent and mutually parallel central axes, said compression load being applied to the rolls to effect a deformation of each roll in a substantially elliptical cross section , square or rectangular. The method can also be applied to unique rolls. The method comprises the steps of: - placing one or more rolls on a support surface, between the opposing perforation plates and a top support plate, applying a compression load sufficient direction on one or more rolls operated the plates of perforation, to substantially deform the rolls until one or more rolls come into contact with the support plate; - release the compression load. It is assumed that the continuous wound paper web can be compressed, and that the step of applying a directional compression load is effected by applying a compression load that deforms the rolls into a substantially elliptical shape, without flattening the central opening in said roll or rolls of central flow. The compression load can be applied by placing a single or multiple parallel rolls on a flat support surface between a pair of opposed perforation plates, their main surfaces being parallel to the longitudinal axis or axes of said products. Subsequently, an adjustable support plate is placed on the product or products, parallel to the support surface. The actuators acting on their respective perforation plates are then activated to apply a compressive force on the product or products. The roll or rolls are compressed into an elliptical cross-sectional shape until the support plate is contacted by the peripheral surface located along the major axis of said cross-section of the roll or rolls. Finally, the compression load is released. Due to a certain spring effect After the roll or rolls are released when the load is released, the roll or rolls are compressed a predetermined amount beyond the desired elliptical shape exhibited by the roll or rolls while under compression. In order to achieve the correct amount of compression, the support plate is adjusted to a desired distance from the support surface. A central flow dispenser according to the invention can be adapted to be used with central flow wound paper or nonwoven meshes of different volumes, as well as different weights, widths and tensile strengths. Said rolls of paper can be without core or have a central core cracked, allowing it to be dispensed in central flow. The present invention can be applied to any type of compressed central flow rolled paper product.

The dispenser comprises a first section 1 for attaching the dispenser to a wall, a second section 2 attached to the first section 1 and circulating a space for a paper roll, a third lower section 3 arranged to support a paper roll not cylindrical and a fourth upper section 4 forming an upper end surface of the dispenser, A front part of the second section 2, facing the user, has an elliptical shape, while a pair of side portions, extending from the widest part of the second section towards the first rear section 1, is substantially perpendicular to the wall. The elliptical shape of said front part of the second section 2 is arranged to conform to the cross-sectional shape of a central flow continuous paper web roll placed in the dispenser. The third lower section 3 is provided with an outlet port 5 with a surrounding cutting edge 6 for feeding outwardly and cutting the paper from a coreless roll placed in the dispenser. The port of departure does not form an essential part of the invention as such, and will not be described in greater detail. According to a first alternative embodiment, the dispenser is opened by means of a third section connected removably 3, connected to the lower circumference of the second section, in order to load a paper roll in the dispenser. According to a second alternative embodiment, the fourth upper section 4 is provided with a hinge Hi along the line where it joins the first section 1. According to a third alternative embodiment, a unit comprising at least a part main of the front section 2 and the fourth upper section 4 is provided with a hinge Hi in the same location as the previous mode, to allow the unit to be tilted upwards. The unit comprising the second and fourth sections 2,4 can alternatively be provided with a hinge H2 at the front of the dispenser, where a front section 2 meets the third lower section 3, to allow the unit to tilt forward . According to a fourth alternative embodiment, all, or at least part of, the second section 2 can be provided with a substantially vertical hinge H3 H4 located below one side of the dispenser along a line parallel to, or coinciding with, the line where the front section 2 joins the rear section 1. Alternatively, it is possible to locate a hinge H5 along the side of the front section 2 at an angle, starting from an upper or lower corner of either side of the first section 1. Figure 2 shows a plan view of a cross section through the first and second sections of Figure ÍH. The cross-sectional shape of the second circular section 2 has a generally elliptical shape, having a major axis YY, said axis being located in a horizontal plane parallel to the wall in which the dispenser is connected and a minor axis XX, said axis is perpendicular to, and is in the same plane as, the major axis Y-Y. Figure 3 shows a dispenser according to a second embodiment of the invention. Using the reference numbers in Figure IA, the dispenser comprises a first section 1 for connecting the dispenser to a wall, a second section 2 circulating a space for a roll of paper, a third lower section 3 connected to the first section 1 and arranged to support a paper roll, and a fourth upper section 4 forming an upper end surface of the dispenser. The main difference is that the first section 1 is connected to the third support section 3, so that the second circulating section is removed to load the dispenser, as shown in Figure 3. The second circulating section 2 is lowered onto a roll (not shown) placed in the third lower section 3 and held in place by a slight force adjustment, a pressure closure or a similar closing means. Figure 4 shows a plan view of a cross section through the first and second sections of Figure 3. The cross sectional shape of the second circular section 2 has a generally elliptical shape, having a major axis YY, said axis is horizontal and parallel to the wall on which the dispenser is attached, and a minor axis X-X, said axis is perpendicular to, and is in the same plane as the major axis Y-Y. Figure 5 shows a plan view of a cross section through an alternative embodiment of the second section as shown in Figures 1 and 3, including a roll of paper R compressed to a substantially rectangular cross-sectional shape, indicated with dotted lines. The cross sectional shape of the second circular section 2 has a generally rectangular shape, having a major axis YY, said axis being horizontal and parallel to the wall in which the dispenser is attached, and a minor axis XX, said axis being perpendicular a, and it is in the same plane as, the major axis YY. Figures 6a and 6b show the component parts of a dispenser according to a third embodiment of the invention. In dispenser comprises a first section 11 for attaching the dispenser to a wall, a second section 12 attached to the first section 11 and partially circulating a space for a paper roll, a third lower section 13 arranged to support a roll of non-cylindrical paper and a fourth upper section 14 forming an upper end surface of the dispenser. The third lower section 13, is provided with an outlet port 15 with a surrounding cutting edge 16 for feeding out and cutting the paper of a coreless roll placed on the dispenser. The port of departure does not form an essential part of the invention as such, and will not be described in greater detail. The third section 13 is an integrated part of the first section mounted on the wall 11, which in turn includes a reinforcing panel 17 delimited by an upper part 18 and a pair of side edges 19a, 19b. The second and fourth sections 12, 14, form a unit that are removably attached to the upper and side edges 17, 18 of the first section 11 and the outer circumference of the third lower section 13, in order to load a roll of paper in the dispenser. Figure 6a shows the unit comprising the second and fourth sections 12, 14 removed from the dispenser assembly, while Figure 6b shows a wall mounted unit comprising first and third sections 11, 13. The unit mounted on the wall and The removable unit is provided with a number of resilient pressure connectors in cooperation to hold the units together. These connectors will not be described in detail since they are not part of the invention and are only indicated in Figures 6a and 6b. Figure 7 shows the parts of components of Figures 6a and 6b assembled in a dispenser, including a roll of paper R indicated with dotted lines. Figure 8 shows a plan view of the dispenser assembled in Figure 7. As can be seen of this figure, only the outer part of the second section 12 has a half ellipse shape substantially conforming to the shape of the paper roll R. From the widest part of the second section 12, a pair of substantially vertical side walls 20a, 20b, extend toward the wall to join the side edges 19a, 19b of the first section 11, having a rectangular shape and being attached to the wall. Said wider part of the dispenser coincides with the major axis Y-Y in this example. Said dispenser could be symmetric about the minor axis X-X only. Figure 9 shows a horizontally mounted dispenser according to a fourth embodiment of the invention. As in Figure IA, the dispenser comprises a first section 21 for attaching the dispenser to a surface and a second section 22 attached to the first section 21 and circulating a gap for a paper roll. In this embodiment the first section 21 is attached below a kitchen unit, such as a cupboard, while the second section 22 supports a roll of non-cylindrical paper with its central axis parallel to the front surface of the kitchen unit. A third section 23 is disposed at one end of the dispenser and is provided with an outlet port 25 with a surrounding cutting edge 26 for feeding outwardly and cutting the paper from a coreless roll placed in the container. dispenser. Opposed to the third section, a fourth section 24 forms an end surface that can be opened to refill the dispenser. The section 24 is provided with a hinge He adjacent to the line where it joins the first section 21. To open the dispenser, a button 27 is operated in the fourth section 24 to release a resilient capture means. According to an alternative morality, a dispenser unit comprising the second, third and fourth sections 22, 23, 24, the first section 21 can be joined by means of one or more guides. This could allow the user to slide the unit in a horizontal direction, either in a direction parallel to the central axis of the roll or at right angles to this direction towards the front of the kitchen unit. Figure 10 shows a horizontally mounted dispenser according to a fifth embodiment of the invention. The embodiment differs from said fourth embodiment in that the dispenser is mounted under a kitchen unit at right angles to the front of the kitchen unit and said fourth embodiment. The dispenser comprises a first section 31 for attaching the dispenser to a surface below the kitchen unit and a second section 32 attached to the first section 31 and circulating a space for a paper roll. The second section 33 supports a roll of paper not cylindrical with its central axis at right angles to the front surface of the kitchen unit. A third section 33 is disposed at the end of the dispenser facing the user and is provided with an exit port 35 with a surrounding cutting edge 36 for feeding out and cutting the paper of a coreless roll placed in the dispenser. Opposed to the third section, a fourth section 34 forms an end surface facing towards a wall on which the kitchen unit is mounted. To refill, a dispensing unit comprising the second, third, and fourth sections 32, 33, 34, is joined to the first section 31 by means of one or more guides (not shown). This will allow the user to slide the unit in a horizontal direction, either in a direction parallel to the central axis of the roll, towards the front of the kitchen unit, or, according to an alternative mode, at right angles to this direction. Figure 11 shows the perspective view of a dispenser according to a sixth embodiment of the invention. This dispenser has a housing comprising a first section 41 for attaching the dispenser to a support surface and a second section 42 at least partially enclosing a radial circumference of a roll of continuous paper mesh R. According to this embodiment, both ends of the dispenser are provided with a opening for dispensing a continuous paper web from said roll of continuous paper web R, said web is located with its central axis in a substantially horizontal plane. A dispenser of this type can be refilled by a user holding the edge 43 of the second section 42 that is not attached to the first section 41 and applying a force at right angles to the plane of the first section 41. A new roll of Continuous paper web R is inserted from either end of the dispenser, and held in place by a force applied by the second section 42. According to a first alternative, shown in Figure 12, the second section 42 joins the first section 41 by means of a hinge loaded with spring H7. This hinge allows the second section to swing at the position indicated at 42a to refill, whereby the second section is released to take the position indicated at 42b to keep the roll of continuous paper mesh in place. The spring force exerted by the hinge H7 must be sufficient to prevent the roll of continuous paper mesh from moving during a dispensing operation. Also, as the roll begins to deplete and partially collapse, the second section 42 should be allowed to swing toward the first section 41 to maintain the spring force.

According to a second alternative, shown in Figure 13, the second section 42 joins the first section 41 along a line indicated at point 43. In this case, the second section is made of a suitable resilient material . When operated by a user, the second section is resiliently deformed at the position indicated at 42c to refill, whereby the second section is released to take the position indicated at 42d to hold the roll of mesh in place. The resilient properties of the material should be such that the spring force exerted by the second section is sufficient to prevent the roll of continuous paper mesh from moving during a dispensing operation. Also, as the roll begins to deplete and partially collapse, the second section 42 should be allowed to flex further towards the first section 41 to maintain the spring force. According to a preferred embodiment, the first and second sections are made of a single piece of sheet metal such as stainless steel. Figures 14 and 15 show a pair of cross-sectional plan views schematically illustrating the size relationship between a known dispenser for cylindrical paper rolls and a dispenser for non-cylindrical paper rolls according to the invention. As can be seen from the modality shown in these FIG., the width Y of the dispenser according to the invention is larger than the corresponding width Yi of a known dispenser. However, depending on the way in which the roll is compressed and the properties of the roll, the width Y2 may be equal to or greater than Yi. It can also be seen that the depth of the dispenser X2, or the extension at right angles to the wall, is notoriously less than the depth X2 is 25-50% less than Xi, although the relationship between Xi and X2 is 25-50% less than Xi, although the relationship between Xi and X2 can usually be within the 0.5 Xi < X2 < 0.9 Xi depending on the size of the roll, the internal diameter of the central hole, the degree of compression, roll density and / or other parameters. The relationship between Yi and Y2 will, of course, vary according to the type of compression. For example, a winding roll compressed to a rectangular shape can give the ratio Yi = Y2, while a roll that has flattened with little restriction of the side sides will give a ratio Yi > Y2 The invention also relates to a method for forming a central flow wound paper web product for use in a dispenser according to the invention. Each rolled paper web product side comprises a length of paper wound on a cylindrical expandable mandrel, which is removed to produce a coreless roll. Such a roll can be somewhat resilient in a substantially radial direction, depending on its roll density. According to the method, the rolls are arranged in a predetermined arrangement having at least one layer of adjacent and mutually parallel central axes, said compression load being applied to the rolls to effect a deformation of each roll in a substantially cross section elliptical, square or rectangular. The method can also be applied to the deformation of rolls alone. The method comprises the steps of placing one or more rolls on a support surface, between the opposite perforation boxes and a support plate, applying sufficient directional compression load in said one or more rolls actuating said perforation plates, to substantially deform the rolls until one or more rolls comes into contact with the support plate and relieving said compression load. It is assumed that the continuous wound paper web can be compressed, and that the step of applying a directional compression load is effected by applying a compression load that deforms the rolls into a substantially elliptical shape, without flattening the central opening in said roll or central flow rolls. The central opening may be deformed, but must be sufficiently open to allow paper to be dispensed therethrough.

The compression load can be applied by placing a single roll or multiple parallel rolls on a flat support surface between a pair of opposed perforation plates, their main surfaces being parallel to the longitudinal axis or axes of said products. Subsequently, an adjustable support plate is placed on the product to products, parallel to the support surface. The degree of compression and therefore the elliptical shape of the rolls can be controlled by adjusting the distance between the support surface and the support plate. This is achieved by adjustable means comprising hydraulic cylinders, ball screws, threaded elements, or the like. The actuators, such as hydraulic cylinders (not shown), acting on their respective drilling plates are then operated to apply a compressive force on the products. The roll or rolls are compressed into an elliptical cross-sectional shape until the support board is contacted by the peripheral surface located along the main axis of said cross-section of said roll or rolls. Finally, the compression load is released. Due to a certain back spring effect, the roll or rolls when the load is released, the roll or rolls are compressed a predetermined amount beyond the desired elliptical shape exhibited by the roll or rolls while under compression. In order to achieve the correct amount of compression, the Support plate is adjusted to a desired distance from the support surface. By adjusting the distance between the support surface and the support plate and applying a higher compression force to the perforation plates and / or applying the additional compression force by means of the support plate, the final shape of the roll or rolls can be control yourself In this way, it is possible to produce rolls having a desired elliptical shape or to produce a rectangular or square shape. For example, by applying superior compression force to the perforation plates without adjusting the relative distance between the support surface and the support plate, it is possible to give the roll or rolls an approximate rectangular shape. Rolls that have a rectangular or square shape can be packed closer and occupy less space during transport. The invention . it is not limited to the modalities described above and may vary freely within the scope of the appended claims.
