on the other side of the fiber beam are arranged «each this plate is movable around a horizontal one Axis which is parallel to the direction of movement of the transport organ «, each axis is further connected to the upper edge of the corresponding one Plate Tuck plates, which represent movable deflectors (guiding screens), are set in a synchronized oscillation movement, their frequency swisehen 240 and 600 vibrations per minute and which has such an angular amplitude that the Fiber beam transmitted oscillations the distribution of the fibers over the entire width of the transport organ enable",

Also known is the simultaneous use of one or more such devices for the production of fibers that sankrecht next to each other Direction of movement of the transport organ »Each of the movable deflectors is synchronized, but iaxi a phase shift operated so that at every moment the different fiber beams converge on the transport element.

The invention is based on the object of improving the devices of the type described, see above that one obtains fleeces or mats made of fibers which have a great boisogenicity, without having to use any movable distributing organs.

BATH 109846 / 1624-

To solve this problem, the invention is thereby characterized in that the spinneret or the spinnerets arranged above the transport member are below the level of the blowing organs with channels causing the drawing out of the thin streams or nozzles are provided which have two large surfaces of substantially planar shape, their Planes convergent in the direction of flow of the gaseous fluid and with respect to the major axis of these channels are symmetrical, the exit cross-section of the channels is at least equal to their entry cross-section, and the channels the channel gaseous fluid as well as induced air or induced fluid, such that the entrained fibers are distributed and their even distribution on the transport organ is effected »

By using these channels it takes place pulling out the thin streams of material by means of of the fluidity through the canals evenly, without the thin streams tending to change direction towards the center and differ from the Remove the edges of the canal, leaving fiber flavors It has been shown that the fibers obtained form a uniform whole at the exit of the canal, which makes a uniform whole Distribution of ßer fibers on the transpox organ

109846/16? / *

Another feature of the invention is that the channels are provided with means for selective pressing (constriction) which allow the shape of the outlet cross-section to be changed in such a way that the flow and sifting of the gas jets entrained by the fibers and thus the distribution of these fibers on the transport element be mn be influenced "

The means of pressing can be interpreted as robbing a set which act individually on the lower part of each large base of the canal and on one in front Channel independent fixed part are screwable.

Examples of how this can be done in detail are given below covers a large width at the level of the transport organ. In another case, on the other hand, the pressure is set in such a way that a considerable clear opening is obtained with parallel hands. It is then found that the track of the strands or bundles (tufts) on the transport element is much narrower, and it is true their width d in r order of the length of the spinneret itself "in

^: 109846/1624

in still another case one brings about in-between Positions such that you press the outer screws and loosen the central screw. You get then a bundle whose track on the transport = »organ approaches the circular shape Loosen the outer screws and keep the central screw pressed, the beam splits into two and the fibers are distributed on the transport organ in two places. One can do this by appropriately setting the AnpreSschraubsn received fiber beams that have different cross-sections and on these or that point of the transport organ are directed.

A further feature of the invention is that the spinneret, the blowing element and the fixed head, which are associated with one another, are arranged perpendicular to the direction of movement of the transport element. Because the chewing output can be regulated, it is possible to spread the fiber beam smoothly over the entire width of the transport organ. This procedure results in combination with the forward movement of the transport member to achieve homogeneous Faservli ie @ _e Because the channel se its output is adjustable, you came mm. In the same way, the two de ©

Another advantageous Kerkioal of the invention is that the channels such Profile gives that you can go from every opening of the spinneret through the blowing organ and the channel can see at least the full width of the transport organ *

Another advantageous feature of the invention is that two or more devices according to the invention are used, which are side by side are arranged along a common axis that is parallel to the direction of movement of the transport member is. In this way, each device creates an elementary fleece the width of the transport element, and the elementary! o these are superimposed on each other without affecting the distribution of the fibers in any way is disturbed. This avoids the presence of lira or tufts of fibers in the final product.

According to another important feature of the invention, one may adjust the directivity of each channel so that each of the spinnerets acts _t and only one zone of the conveying member that the totality of the channels causes a uniform distribution of the fibers on the whole surface of the transport organ.

FAn further feature of the invention is that the device has a Vert ei lungs · »and Formlingeorgan ,, the tiündet near the transport member and having SWEi large areas of substantially planar shape at least over part of their length in the Converge exit section adjacent zone o

This distribution and research organ can be placed directly below the level of the blowing organs which cause the fibers to be drawn out, and the ducts or nozzles according to the invention form an integral part of the two large surfaces of the substantially flat shape of the distribution and Forming organ.

According to the invention it is further provided that this organ »is arranged indirectly below the level of the channels or nozzles and that induction is effected by air in the interior of this organ between the exit from the channels or nozzles and the entry into this body "

Yet another feature of the invention is that uniformity, strength and decrease the speed of flow of the fibers entrained gaseous fluid in the distribution and

Formuugeorgan is secured by the united Effect of changing the cross-section of this organ and the introduction of additional fluids,

Another feature of the invention is that the means provided for introducing additional fluids are arranged and controlled in this way are that the amount of fluiduras based on the unit area through all cross-sections of the distributor treatment and shaping organ through essentially is constant β
