It is known to use flexible connective organs, e.g. B. threads to attach to fabrics, especially textiles, by passing the two ends of a hairpin through the edge of the fabric Loop of thread running around the edges in the same direction pulls together through the thread loop. Such thread entanglements are used either to Attachment of labels or the like to lengths of fabric or as so-called MarMerfäden for identification of defects that can occur in textiles.

For attaching flexible binding organs, e.g. threads, to flat structures, especially textiles, a device is known with a thread cutter, with two longitudinally intersecting movement paths displaceable work organs, of which one is a vertical puncture needle for forming an open piercing the sheet-like structure Loop of the binding organ (thread) with the loop lying on the underside of the fabric is while the other is a gripper for reaching through the loop for the purpose of pulling the over the Flat structure upwardly protruding legs of the thread loop through the loop, as well as with an actuator for tilting and raising the loop over the edge of the fabric in FIG the trajectory of the second working organ, which can be carried by a single hand and the same hand-operated device has control means, which with the puncture needle and the gripper as well as with the steering element are connected in such a way that when the control means are actuated by hand the said organs execute coordinated movements to create a closed Form loop.

Experience with this known device has shown that the process of thread entanglement is fraught with difficulty. Often, the detection of the thread loop does not work properly in front of itself, and therefore incorrect entanglements occur.

In a device for attaching markings to laundry, items of clothing or the like. It is known to use a hook-shaped gripper for the thread loop. This well-known gripper leads the thread loop but after piercing through the textile web and the label only on the other Fabric side, but does not open the thread loop. In addition, this known gripper performs a intricate movement, which is not without noticeable effort, more space-consuming and more complicated, more mechanical Drive means can be realized.

Leg passed under the clamping spring above. The lever arm 93 has meanwhile come into contact with the lever arm 105 , and during the remaining downward movement of the housing part 16 the lever 104, 105 is accordingly pivoted. The movable shear blade 99 thereby moves upwards, so that the thread running through its notch, which is part of one leg of the loop formed by the needle 22, is cut. ίο The housing part 16 can now be pivoted upwards under the influence of the springs 19. The cams 36 and 37, which had previously made one complete revolution, remain here thanks to a ratchet clutch at rest, while the cutter 99, the arm 94 and the pusher 69 return to their original position. The tissue can now be pulled out of the device together with the closed thread loop formed by the device, which is located at the edge of the tissue. The device can easily be used again for the production of a new thread loop ready because the thread coming from the bobbin is between the clamp spring and the spine of the underlying fixed shear blade 98 is clamped and in front of the loop-forming Needle 22 passes through it. By a simple pushing movement on the housing part 16, the closed Loop can be made completely. In summary and on the basis of FIG. 3 to 8 considered the closed loop is formed as follows: Piercing through the plate 71 and the textile fabric 100 , the needle 22 carries the thread 101 forming a loop with it and brings it in front of the hook 58 of the bracket 56 (FIG. 3). The bracket 56 shown in Fig. 3a is guided by a plate 102 behind and along the plate having the slot 57, in front of which the slide 61 is located. This engages the shorter leg of the bracket 56 and pulls it as the next operation to the left with reference to the drawing (FIG. 4). The hook 58 engages the thread loop 101, the longer leg of the bracket 57 guided in the arcuate slot 57 and having the hook rising and bringing the loop 101 in front of and around the edge of the textile fabric 100 . At the same time, the needle 22 retracts and, thanks to the helical profile of the notch of the hook 58, the loop spreads somewhat laterally. This allows the latch needle 24 to reach through the loop in the following operation (FIG. 6) and to grasp the two strands of thread protruding from the textile fabric. By advancing of the slide 61, the bracket 56 has meanwhile returned to its starting position. To close the loop 101 , the latch needle 24 is finally withdrawn (FIG. 8). In the meantime, the thread has been cut to the desired length by the cutting device, not shown here. Claim: Device for attaching flexible binding organs, e.g. threads, to fabrics, especially textiles, with a thread cutter, with two longitudinally intersecting movement paths displaceable work organs, one of which is a vertical puncture needle to form an open loop of the binding organ (thread) penetrating the fabric on the underside of the fabric lying loop, while the other is a gripper for reaching through the loop for the purpose of pulling the leg of the thread loop protruding upward over the fabric through the loop, as well as with an actuator for tilting and raising the loop over the edge of the Flat structure in the path of movement of the second working member, the device which can be carried by a single hand and operated by the same hand has control means which are connected to the puncture needle and the gripper and to the actuator in such a way that when actuated the control means execute said organs by hand in coordinated movements to form a closed loop, characterized in that the actuator has the shape of an approximately U-shaped bracket (56), one leg of which is pivotably mounted on a slide (61) and the other, somewhat longer, leg provided with a hook (58) at the end is guided in a curved link (57) on the device housing, the hook (58) provided on one end of the bracket for raising and spreading the thread loop (101) only detects a limb of the loop of thread, and that the and of the two is configured as a latch needle (24) over the sheet upwardly projecting loop legs by the thread loop (101) again recyclable gripper needle insertable through the spread and superscript thread loop (101) under seizure.
