A denotes the feed device with which the prepared, arranged in layers one on top of the other Threads 1 j fibers and the like pushed forward will. This feed device A consists essentially of two adjacent packages B, C feed sheets 2, 3 » between which the threads 1, fibers and the like come to lie. Each feed sheet 2, 3 consists of a top plate, e.g. 3a, and a bottom plate, e.g. 3b (Figure 3), between which retractable and extendable gripper organs, e.g. 3c, are arranged. In the embodiment shown in the drawing, the gripper organs, e.g. 3c, have the shape of a claw or a barb.

These gripper organs, e.g. 3c, are on a tongue 3e arranged, which is mounted displaceably to the feed device of the threads 1, fibers and the like. The shift of this Tongues 2e, 3e take place, for example, with the aid of the pressure medium cylinders 4, 5, whose piston rods are connected to bearings 6, 7 are. These bearings 6, 7 are slidably mounted in carriers 8, 9, the latter under the action of pressure medium cylinders 10, 11 stand, with the help of which the packages B, C in the feed direction or can be moved back and forth in the opposite feed direction.

In the top and bottom plate, e.g. 3a, 3b, slots 3d are incorporated (Figure 6) through which one Position the gripper organs, e.g. 3c, reach through and thus protrude over the top and bottom plates 3a, 3b.

209842 / 0S34

21U859

If, on the other hand, the corresponding tongue, e.g. 3e, is moved in the opposite direction, the gripper organs are released, e.g. 3c, out of the slots 3d and in this way disappear completely between the top and bottom plates 3a, 3b of the Feed sheet 3.

This process can best be compared to extending or retracting a cat's claws.

With 12 an endless, intermittently revolving needle belt is referred to, the needles are mounted so that they are in Point in the direction of the end face of the fiber stack consisting of the individual layers of the threads 1 and the like.

The feed device A is assigned a frame 13 (FIG. 1) which can be adjusted in the feed direction and which is adjustable in the feed direction Fibers 1 protruding beyond the feed blades 3 hold together.

The lower edge of the frame 13 eats a pivotable Counterholder 14 assigned (Figure 7).

The reference numeral 15 denotes a plate which is displaceable in the horizontal direction and which the needle tape 12 in FIG punctures the end of the fiber stack.

A cutting device is indicated by C, which at the embodiment shown in the drawing is designed as a lifting and lowering band knife. By lowering this Cutting device C the fiber staple is cut in such a way as shown in FIG. 7 of the drawing. The needle tape 12 with the cut fibers 1 is guided over a roller 28 and fed to a gelling device D. In this case, an adjustable roller 16 provided with elevations equalizes those in the needle tape 12 stuck fibers.

A carrier is inserted between the two rollers 17, 18, on which a layer of binder has previously been applied became. The needle tape 12 with the fibers and the like stuck in it is now together with the carrier 19 via a The heating drum 20 is guided, then passed through a cooling section 21 and fed to a release roller 22.

The pile is then wound onto a roller 23, while the needle tape 12 freed from the fibers is in the area of the Feed device A is guided.

Instead of the carrier 19, a removable and reusable coating pad can also be used if there is no carrier Tracks are to be produced.

The mode of operation of the device according to the invention for carrying out the method is as follows

The starting point is that position which the individual parts of the device in FIG. 1 assume. The end face of the fiber stack is at a certain distance from the needle tape 12; it is now necessary to move the end face of this fiber stack up to the needle tape 12 with the aid of the feed device A. For this purpose, the gripper elements 2c, 3c are moved into the operating position by the associated pressure cylinders 4, 5, in which case these gripper elements 2c, 3c pass through the slots, e.g. 3d, and in this way over the top plate, e.g. 3a, and the bottom plate , e.g. 3b, protrude. The gripper members 2c, 3c penetrate the fibers of the fibers lying on both sides of each feed sheet 2, 3. Then the pressure medium cylinders 10, 11 are actuated in such a way that the packets B, C _{lying next to one another are moved to the right 9} in the figure of the drawing, that is, in the direction of the needle belt 12.

Then, the gripper members 2c are corresponding movement of the gripper tongue 2e in the space between the upper and lower plates 2a, 2b retracted, so that the connection between the G _r jealous organs and 2c is achieved the fibers. 1 The package B then moves to the left in FIG. 1 of the drawing, the feed blades 2 sweeping past along the corresponding fiber layers with practically no resistance. In the end position, the gripper organs 2c are then extended again and thus penetrate the fibers 1.

Now the gripper members 3c are in the inoperative position transferred so that they separate from the fibers 1. The package C is then moved to the left in Figure 1 of the drawing, wherein in the end position the gripper members 3c are transferred into the operating position such that in this position the Gripper organs 2c, 3c of both packages B, C grasp the fibers again and are ready for the feed again.

The stationary needle tape 12 is now pierced into the end face of the fiber stack by means of the plate 15. A pressure strip 27 keeps the edge of the fibers straight and enables the needle tape 12 to pierce properly.

Then the part with the cut fibers of the needle tape 12 and the cutting device C are put into operation, the cutter C moving downward during the movement of the needle tape 12. Through this movement becomes performs a section as shown in Figure 7 of the drawing. The cut is of course made so that the knife does not Needles of the needle tape 12 hits. The corresponding section of the needle tape 12 is now full of threads and the like filled up. The part of the needle tape 12 covered with the cut fibers is moved over the driven roller 28 at the start of cutting deflected and led into a compensation loop.

The swiveling pressure bar holds during the cut 27 the lower edge of the fiber stack firmly.

After the cutting process is finished, take the cutting device C and the plate 15 in turn their starting position. At the same time, the feed device A also re-enters Action.

Then the one provided with a binder layer Carrier 19 inserted between the rollers 17, 18 and pressed against the needle tape 12 filled with pasers and the like. Of the The fiber-filled sections of the needle tape 12 together with the carrier 19 are then passed over the heating drum 20 and, after deflection, fed to the cooling section via a further roller 24. Through the heat and cold treatment, the fibers become bound in the binder layer of the carrier 19, wherein the hold between these parts is so great that the fibers bound in the binder layer of the carrier 19 by means of the release roller 22 can be detached from the needle tape 12 and wound onto a roller 23 and the like. Now that again The needle tape 12 that has become free then moves in turn to the feed device A, where it is stopped and only when it is inserted of the cutting process is set in motion again «. The needle tape 12 always moves only with the device C. and the plate 15 together when these after the cutting process go back to the starting position.

A rotatable brush 25 cleans the needle tape 12, which is additionally equipped with a pipe that is acted upon by compressed air 26 can be cleaned.

It is useful to make the needles of the needle tape 12 shorter than the pile height by the adhesive bed depth. It exists but also the possibility of dimensioning the needles of the needle tape 12 to be the same length or longer than the cut pile fibers.

209842/0934

21U859

It is also within the scope of the invention, the needle tape 1.2 with needles of different lengths, the longer needles being pointed, the shorter ones being round. The Koni city, the strength and the density of the needles of the needle tape 12 are expediently chosen so that the pierced, cut Pole material is held in an upright position »Only the longer needles pierce the adhesive layer and the carrier.

You can pierce an insert with long needles in the needle tape 12, which is elastic and so thick is that the remaining free length is around the adhesive bed depth is shorter than the pile fiber height to be cut,

That part of the band knife which the roller 28 is facing, is ground hollow, the radius of the hollow ground approximately equal to the radius of the roller 28 with needle tape thickness is.

The cut, in the needle tape 12 anchored pile fibers leveled before immersion in the adhesive bed.

The needle tape 12 with the cut pile fiber material is advantageously looped around a roller, the needles pointing in the direction of this roller in order to pass through in this way Belt tension to generate the required hold-down pressure.

According to a somewhat modified embodiment of the invention, the pile material can be used in twice the amount of the pile are advanced and cut, with a second needle tape piercing after the deflection and the pile material between these two needle ribbons is cut.

The binding and gelling device continues to run, while the feeding and cutting device runs in batches work.
