In the area of the knife 25 can be seen that in the immediate vicinity of the knife, when the latter is in his extended position, as shown hatched in FIG is arranged, a sturdy slide, which has enlarged passages that the maximum holding tape width can accommodate »The slide 34 is S-shaped and arranged so that the tape tom over part of the Federal is transported away. At the bottom of the slide there is a pair of air-operated drive retractors 35 and 36, between which the tape is aligned, and which serves to hold the tape over the remainder of the length of the chute to force upwards.

The slide and the rollers are adjustable and are connected to a base 37 for this purpose, the has vertical projections which restrict the base and chute from vertical movement. These base protrusions lie between vertical guide plates 38 and 39 which are part of the frame 19 · A piston-cylinder unit 41, which is attached to the upper end of the guide plates 38 and 3ü, has its piston rod end connected with the base 37 for the vertical adjustment of the slide 34 relative to the tape into a tape-receiving position and off this out. At the top of the slide is 19 on the frame a scrap chopper 42 attached, in which the retaining strap is guided and which has the shape of any commercially available Scrap chopper as described, for example, in US Pat. 2,500,772, issued to E Reed on March 11, 1950. The tapes fall after from that behrottzerhacker are cut into short lengths, into a Collection station 43, where they can be removed at any time.

It should be noted that the hold-down roller 12 and the rollers 35 and 36 are covered with rubber,

so that they have a maximum driving effect on the hand and It is equally important to determine that the air motor drives the pinch rollers 35 and 36 allow the motors to stall when the hold-down roller 12 is not driving the tape at one speed drives forward, which corresponds to the speed of the holle 35 and 36 after breaking the tape. Although not part of this invention, a brief mention should be made of this device, especially since the drawing forms part of the Device to which tape is fed shows. In this regard, the horizontally arranged guide 4-1 recognize, which serves both to lift the front end of the tape from the collar and it as it runs to a Cut off processing plant 45 including the first of several tape feed and bending rollers.

A brief explanation of the above apparatus will now be given. Assume that a bundle C lies on top of the Hollen IU and 11 of the hoist and is raised to the position shown in the drawing. As previously mentioned, the Hold-down roller 12 by actuating the piston-cylinder unit 32 are moved to move according to the different heights of the collars as a result of their different To adjust the diameter. As already mentioned, the holding strap B is in the collars so that it falls directly under the knife 25 of the holding strap removal device. After this the roller 12 touches the collar and the tether, the piston cylinder 29 is actuated, whereby the hammer head 28 hits the knife carrier 24, which was previously lowered by actuating the piston-cylinder unit 27 and causes that the knife 25 cuts the tether. As soon as this happens, the piston-cylinder unit 27 lifts the knife 25 in its rest position, the hold-down roller 12 is actuated to feed the tape and the holding tape in the direction on the processing plant. It should be noted that the rollers 10 and 11 were previously rotated so that the

The end of the tape is held at a point between the rollers 12 and the guide 44, which supports the tape running to the processing system. Thus, 35 and 3Ü forced upon rotation of the roller 12, the front end of the tether to Einlaul into the chute 34 and the pinch rolls, which has been descended by the piston-cylinder unit Al to the position shown in Fig. 1 position. When the chute is in this position, the retaining band B is bent from the collar C by the pushing and pulling action of the roller 12 and at the same time the front end of the band is fed via the guide 44 to the processing system 45 do not correspond to the speed of the drive rollers 35 and 36, the air motors for driving the free rollers switch off until a sagging has formed in the holding band between the drive rollers and roller 12, whereby these can drive the band further into the chute 34. As soon as the front end of the tether runs out of the upper end of the rod 34, it is picked up by the scrap chopper 42 and divided into short lengths, which then fall into a mutton station 43. In the meantime, the tape has been fed to the processing plant . Here, if is usually involved more than one complete binding, wirü thereby ensuring Ic ", the whole tether is under the roller 12 and the slips? 34 to the time when the shade 12 stops the forward motion of the tape. A little- collar is to be machining tet, k _n η roller 12 by actuating the piston cylinder unit be powered up 32 and the driving rollers 35 and 30 drove the rest of the retaining strap into the chute, where it is transported away quickly and automatically.

Normally, according to L.nt, the strap is removed from your Federal government actuated the piston-cylinder unit 32, whereby the iiahmen IT and thus the Holle 12 booted up by the dog
