ORIGINAL
e e e 0 Name of Applicant: ASHLEY LEACH ASSOCIATES PTY. LTD.
Actual Inventor(s): Ashley LEACH and Ralph SKENDZIC Address for service in Australia: CARTER SMITH BEADLE, Qantas House, 2 Railway Parade, Camberwell, Victoria, 3124, Australia, Attorney Code SA.
Invention Title: CABEL LABELS Details of Associated Provisional Applications: Nos: PK7009 The following statement is a full description of this invention, including the best method of performing it known to me/us: -1- -2r TITLE: CABEL LABELS This invention relates to adhesive labels and in particular to adhesive labels manufactured as a continuous batch product. The invention also relates to an improved method of manufacturing adhesive labels as a continuous batch product.
BACKGROUND OF INVENTION: Adhesive labels on a support sheet are known to be provided with printed matter by means of printing plates to which a printing ink, paint or other coating is applied, the plate then being used to apply the colour to a removable clear plastics label sheet which is adhering to the support sheet. In the manufacture of labels where a significant area of the label sheet is to be covered with colour, the colour to date has been applied as a fine dot pattern. The dot pattern application of dye is used instead of a solid mass of ink, as paint or the like would be subject to cracking, crazing or peeling from the label sheet. The current method of fine dot pattern application has limitations, in particular when the label is applied to a surface, the colour of the underlying surface will show through the label between the printed dots, leading to visibility or legibility problems.
Another known method of producing adhesive labels which have an area of solid colour on a part of each label involves a manual operation of laying plastics tape having a solid colour. This tape has an adhesive backing so that the tape is laid on the label sheet. The label sheet is then cut to form the labels of the desired size which can be peeled from a support sheet. This process is labour intensive and therefore expensive.
Furthermore the labels used to date depend on, among other materials, r r mwspe#6840 16 June 1992 -3acetate base adhesive label sheet, for example cellulose acetate which suffers dimensional instability, particularly in response to cold flow, heat and moisture absorption. The fibers of cellulose acetate weaken about 80'C, are difficult to dye uniformly and constitute a fire hazard due to their flammability. Other materials, for example vinyl, have been used for labels but only using the prior art methods as previously detailed.
OBJECT AND STATEMENT OF INVENTION: It is an object of the invention to provide an improved adhesive label having substantial areas of solid colour and to provide an improved method of manufacturing adhesive labels as a continuous batch product.
Accordingly the invention provides a method of manufacturing adhesive labels as a continuous batch product including the steps of: i advancing to a print station a support sheet having a label sheet adhering thereto, the label sheet being capable of being peeled from the support sheet with 454*4S S 15 adhesive remaining on the rear face of the label sheet; introducing a printing foil so as to closely overlie the label sheet at the print station; advancing a heated plate at the print station so as to apply heat and pressure at selected sites or in a desired "i pattern or configuration to the foil to press the foil against the label sheet so as to bond foil to the label sheet selectively, so as to form a desired pattern or *44o 20 configuration of bonded foil to label sheet; and retracting the heated plate and removing unbonded foil; the support and label sheet with bonded foil pattern sheet being withdrawn from the print station after the retraction of the plate.
The support sheet carrying the adhesive label sheet which is initially fed to the print station may be either a support web or an individual cut sheet. In the case of a support web, the web for example may be fed from a roll on a substantially continuous or intermittent feed basis. The support sheet may for example be a paper sheet, provided with a coating if desired in order to enable MAW:NB:6840.spc 21 Juary 1994 4 the label sheet to be peeled from the support sheet leaving adhesive on the label sheet. The adhesive label sheet is preferably transparent or translucent so that areas of the label sheet to which foil is not applied remain clear or translucent.
For example the label sheet may be low gloss frosted clear plastics material of the general kind used in adhesive tape rolls used as office stationery.
The introduction of the printing foil so as to closely overlie the label sheet at the print station may comprise advancing a continuous backing web on which the foil is carried, e.g. feeding a backing web from a supply roll. The foil may be of any desired colour, and preferably is a solid colour foil. The 10 material of the foil may be a plastics material which is adhesive or is intimately bonded by its own composition to the backing web.
Preferably the heated plate is advanced into contact with the backing web on the opposite face to the foil so as to press the foil against the label sheet.
The plate provides the required pattern or configuration of the foil to be applied to the label sheet. The plate may be of any suitable material and construction and it may for example comprise a magnesium plate so as to have a suitable heat capacity and being relatively easily worked to provide the required pattern.
Preferably the plate is heated to a temperature at which there is softening of the foil and/or the material of the label sheet so as to thereby achieve intimate bonding or fusion of the foilAto the label sheet. The strength of bonding of the foil to the label sheet is preferably greater than the adhesive force between the foil backing web and the foil so that upon retraction of the plate and removal of the foil backing, the foil pressed against the label sheet will remain bonded to the label sheet.
iThe plaie may be a generally flat plate and in use is reciprocated in mwspe/66,10 16 Juno 1'992 5 synchronism with stepped advancement of the support sheet and foil backing web. Alternatively the plate may be in the form of or mounted to a roller so as to rotate at the same surface speed as the speed of advancement of the support sheet and foil backing web to thereby press the foil against the label sheet.
After the retraction of the plate and advancement of the support sheet a waste border portion of the label sheet may be removed. For example, the border portion may comprise edging around each of the labels and/or along the edges of the label sheet which desirably removed to enable a user to easily 10 grasp a corner of the remaining adhesive label material and peel the label from the support sheet. The removal of the border portion may be achieved by peeling the border portion away from the advancing support sheet and for example rolling the border portion around a rotating take-up roll.
:Prior to, or if desired, after the print station individual label shapes may 15 be cut through the thickness of the label sheet, but not through the support sheet so that individual labels of the desired shape are formed for individual removal from the support sheet. If desired, the support sheet may also be perforated to enable the sheet to be torn along the perforation lines to leave smaller support S"sheets to which a number of adhesive labels are adhesively secured.
Furthermore for continuous stationery of the kind used for computer printers the support web may have holes punched along it on opposite edges to enable use of the support web and adhesive labels thereon as feed stationery for a computer printer, e.g. for computer controlled printing of matter onto the solid colour foil portions of the labels.
The invention further provides an adhesive label comprising a support mwspaH6040 16 Juno 1992 6 sheet having a label sheet adhering or laminated thereto, the label sheet being capable of being peeled from the support sheet with adhesive remaining on the rear face of the label sheet where in said label sheet has a printing foil overlying the front face of the label sheet, characterized in that said label sheet is manufactured from a vinyl or polyethylene derived base.
Preferably the base is a polyvinyl chloride; most preferably MATTE CLEAR SOFT PVC 70101 JAC.
The printing foil may be adapted to receive printing ink and is preferably at least partially opaque.
10 The printed foil is most preferably KURZ V911 white foil which is heat and pressure fused onto the label sheet.
The adhesive for laminating the label sheet to the support sheet is preferably an acrylic adhesive having the following properties:- 15 Adhesion FTM 1 >9/2.5cm Initial Tack (loop tack) FTM 9 5-7 N/625mm 2 Cohesion (lkg/5cm 2 >100 minutes S. Application Temperature Temperature Resistance Minimum Temperature -30 C Maximum Temperature 1300 (Applied to substrate 1 hour) Depends on Print Carrier temperature resistance mwspe#6840 16 June 1992 7 The label sheet layer of the laminate may be segmented with a series of cuts or indentations to effect a backing sheet having a series of discrete labels removable therefrom.
The application of the printing foil may be discretionary with only part of the label sheet of a given discrete label being overlaid with the printing foil in order to effect a label having partial clear vinyl and partial opaque printing foil.
The printing foil may also be applied in the form of a symbol, word or other instructing format.
10 In its most preferred form the labels are adapted for marking cables and have a rectangular form with a portion of the clear label sheet overlaid with printing foil such that instucting information may be applied to the foil whence the label may be folded around a cable and back upon itself such that the clear remainder of the label sheet folds back over the foil to fully protect the instructing information.
Possible and preferred features of the present invention will now be a described with particula; reference to the accompanying drawings. However it i is to be understood that the features illustrated in and described with reference a to the drawings are not to be construed as limiting the script of the invention.
In the drawings: Figure 1 is a schematic diagram of an apparatus for continuously manufacturing labels according to the present invention, Figure 2 is a fragmentary view of border portion removal and the remaining support sheet with foil printed labels thereon.
Figure 3 is a schematic cross-section of a label.
mwape#040 16 Juno 1992 8 The apparatus illustrated provides means for carrying out the various steps according to the method the present invention as described above.
Therefore the construction and operation of the illustrated apparatus will be readily understood by referring to the preceding description in conjunction with the component designations marked on the drawings.
The advantages of the method, apparatus and product according to the preferred embodiment of the present invention as herein described and illustrated include the provision of an opaque label or area of label. That is, the labels can be manufactured so that there is no substantial visibility of a support 0 to which the adhesive label may be applied which in turn could have led to visibility or legibility difficulties. The method and apparatus enable the labels to be manufactured more economically compared to the prior technique of manually overlaying plastic tape. The labels can be continuously manufactured or can be manufactured on sheets e.g. for provision in "book" form.
S 15 The labels produced according to the inveniion are particularly suitable for applications where a clear or translucent portion of the label is desired. For 9 example each label may be printed with approximately half of the label being clear or translucent and the remaining half being printed with a solid colour foil, e.g. a white foil. Such labels can be applied to narrow elongated objects such as electrical cables with desired information being printed or written on the foil and the foil section of the label being first applied to the object. The label can then be wrapped around the object so that the clear or translucent portion overlies the foil section having the printing thereon, the clear or translucent section thereby covering and protecting the printing on the foil.
Referring now to Fig. 3 it can be seen that the label comprises a support mwspe#6040 16 Juno 19192 9 sheet 1 having a vinyl label sheet 3 adhered thereto by adhesive layer 2 wherein the label sheet 3 has a foil layer 4.
The backing support sheet is preferably capable of both push and pull feed through computer printers and is most preferably KV75 having the following properties:- SILICONIZED GLASSINATED PAPER Standard backing paper on JAC paper and synthetic reel stocks. Strong glassine with resilient properties allowing for excellent diecutting results.

oeeoo The particular use of vinyl based labels provides a number of clear advantages over the prior art including high adherence to vinyl based cables which now include the majority of cables produced. The vinyl based labels also have improved resistance to tearing and a high resistance to sustained temperature elevations which may commonly occur in cables carrying high 15 current. The vinyl labels also resist scratching and physical damage.
