    The invention relates to the textile industry, in particular, to mechanisms for forming fabric edges in weaving. A device is known for forming a mortgage edge on a tailless loom with weft feed from stationary reels containing means for holding and retrieving weft thread, two cutting the lengths of thread, one above the other, means for laying the cut end of the weft thread into the machine's shed and the clamp of the weft thread comprising two plates, one of which is connected to an elastic element volume, and the friend has an emphasis for weft thread G. A disadvantage of the known devices is low reliability of operation. The purpose of the invention is to increase reliability. .. The goal is achieved by the fact that in a device for forming a mortgage edge on an shuttleless loom containing means for holding and selecting a weft yarn mounted on a carriage, two knives for cutting the thread, placed-. one above the other, means for. laying the cut end of the weft yarn into the machine's shed and the weft yarn clamp, including two plates, one of which is connected to the elastic element and the other has a stop for the weft yarn, the lower knife has a stop for the yarn, the clamp is mounted on. this knife by means of a screw joint, and the plate with the stop is shaped like a knife and has a gripping surface for the thread placed; Perpendicular to the direction of movement of the knife, with one clamping plate connected to an elastic element made in the form of a clamp, which bends around the knife from the end of the blade and fixed at one end on the knife, and the elastic element is designed in the form of a plate spring fixed on the free end of the scby and in contact with the gripping surface of another clamp plate. FIG. 1 shows the device, a general view; in fig. 2.- side cutter knives with gripping mechanism; in fig. 3 a device, a plan view4 The device comprises, a housing 1 of control mechanisms of the cutting device and a catch hook 2. Weft yarns 3 descend from the feeding containers; located beyond the borders of the pharynx, and pass through the eyes of the chain 4 for weft selection. All weft yarns 3 are fixed in the edge 5 of the fabric being fabricated 6. The device also contains a guide grip 7 a cover 8 of the pattern. The cutting device includes two knives 9 and 10, placed one above the other. The lower knife 10 includes a plate 11, to which the blade 12 with a protruding eye 13 is attached, the Plate 11 and the blade 12 are fixed to the knife 10 by means of screws 14. The upper part of the plate 11 has a gripping surface 15 located flush with the cutting edge 16 of the blade 12.. The gripping surface 15 is perpendicular to the direction of movement of the lower knife 10. The leaf spring 17 is attached to the end 18 of the supporting rod 19, which exerts pressure on the knife in the area of the ear 13. The support bar 19 from the upper part of the ear 13 passes along the side of the blade 12 and its the tail portion enters from the lower side of the plate 11 into the guide slot, in which it is fixed by screws 14. When loosening the screws 14, the position of the rod 19 can be changed to control the pressure force of the spring 17 on the surface 15. To the fixed part 20 of the cutting device one end of the rod 21 is rigidly attached to hold the weft yarns 3, directed parallel to the edge 5 of the fabric 6, the tail part 22 of the rod 21 is folded perpendicularly to the edge 5 of the fabric. Function; Qi of rod 21 consists in ensuring that all weft yarns 3 are in the same zone as the weft of the weft 3, even if they are attached to the edge 5 of the fabric at different points so that the hook 2 MOH can grip the thread. This happens when all the threads 3 round the rod 21, which thus fixes the position from which all cut weft threads depart from the fabric b. The body 1 is not rigidly attached to the frame 23 of the loom, so it can make movements parallel to the edge 5 of the fabric b, making it possible to position the engagement zone 24 in a convenient place relative to the edge 25 of the already made fabric b. It is obvious that the proposed device greatly facilitates the operation of. folding the ends of the U1x1 yarns inserted into the throat to obtain a folded edge. During operation, the device, when placing the means 4 for selecting the weft yarn 3 in front of the guide behind it, the grip 7, engages this thread and inserts it into the throat formed by the weft yarn. mi, with the result that the weft thread gets the direction shown by the position, 3. The selected weft thread is passed through the eyelet 13 of the blade 12 of the lower knife 10, which at this moment is raised. The thread is then
    placed between the gripping surface 15- and the spring 17, where it is fixed. After that, the upper knife 9 is lowered, the thread is cut. The replaceable thread is cut, or rather the segment between the edge 5 of the fabric 6 and the gripping elements 15 and 17, can no longer be confused with: a bunch of other weft threads. The cuttable thread is cut tightly tightened in the engagement zone, enclosed between the part 22 of the retaining member 21 and the gripping members 15 and 17. At the same time as the cutting operation, the pick hook 2 moving to the engagement zone with the cut under the interchangeable thread is moved. -.
    The lower knife is then lowered, and it causes the exchangeable thread to be fastened by the exciting replacement part of the catch hook 2, which, on the return stroke, causes the cut replaceable thread to pass through the warp by moving it away from the catch Elements, and all weft threads 3 and 3 passing through the selector remains attached to the edge 5 of the fabric when they pass through the free zone A formed by the knives 9 and 10 after bending around the vertical part 22 of the retaining element 21. On the other hand, both knives 9 and 10 can only be rotated in the direction In about a common axis of rotation C.
    When it is necessary to enter the weft yarn, for example, yarn 3, the selector leads it to a guide clamp or gripper 7, which grips it when making a turn in the direction indicated by the arrow. 0 Simultaneously, the lower knife 10 pivots from the lower position to the working one, at the same time raising the eye 13. When the lower knife 10 (FIG. 1) is raised together with the eye 13, the weft thread 3 is gripped by the locking 7. The windrow 3 is ready to enter the open shed E formed by the base yarn. Obviously, after the capture of 7 working stroke, the specified thread Z will take position 3. The guide
    0 grip 7, continuing to make its move, t there is no fixed parts O and GI of the thread connected by edge 5 of fabric b and fixed behind the gripping elements. Other part 3
    The 5 strands coming from the spool, on the contrary, lengthen. At this stage, the upper knife makes a movement down and cuts the thread. The loosened portion of the specified yarn is pulled off
    This is 7, while the other part remains tight.
