Looms are known per se in numerous embodiments. In particular there are weaving machines which remove the weft thread from stationary bobbins. Such looms are with a sley, shuttle shuttles that have an entrainment device that takes up the weft thread, and reed, with devices for moving the sley to and fro and for driving the shuttle across the sley through the chain thread compartment and with devices for the chain thread feed and provided for feeding and discharging the weft thread at the ends of the sley.

In weaving machines of the last-mentioned type, the shuttle is designed as a rapier, and the weft thread is fed from devices arranged outside the shuttle in order to be cut off later to become. This enables a variety of shots.

However, such weaving machines are not free from disadvantages. If you use different wefts, so the holder of the shuttle at the ends of the sley is not enough to get into it to be able to introduce selected weft yarns.

The invention aims to eliminate this disadvantage of known weaving machines and provides a special one for this purpose trained take-away device.

According to the invention, this entrainment device is to be introduced into the shuttle Carrier formed, which at the end of the respective flight direction of the shuttle across the sley to and from the web shuttle to a pickup provided at each end of the shop will.

The invention achieves an extremely firm holding of the carrier in the transducers, which in turn makes it possible to choose from a plurality of weft yarns via a corresponding Weft yarn aid arrangement to bring a selected weft yarn into the carrier and this to interweave. This makes it possible to keep a plurality of weft yarns on each side of the sley, selected weft yarns by actuating the aid arrangement accordingly a predetermined pattern can be entered into the fabric.

The invention can also be practically implemented in various ways. As functional has proven to be the carrier for holding the weft yarn from a slide rail provided with two hooks build up in a slot that is slidable between a sheet and a shoe it is provided that in two positions of the sliding loom

The carrier must of course also be reliably attached to the shuttle so that it cannot be detached from it along its path between the pickups. According to a preferred embodiment of the invention, this is achieved by a pair of grippers on springs which are fastened with their ends on both sides of a groove in the shuttle. These springs can be stretched in a simple manner to release the carrier, but reliably hold the carrier in their normal position.

According to an expedient embodiment of the invention, the sensors consist of an The ends of the rails are forked with two prongs, and the carrier is held between the fork prongs. In addition, the transducers are themselves movable. This mobility of the transducer is achieved on the one hand by their pivotable mounting on a rack and on the other hand by that the rack itself is movable in its longitudinal direction via a gear.

Basically it belongs to the state of the art, the weft yarns behind one provided with teeth To feed the weaving sheet to the shuttle via weft yarn aids. For this measure, therefore, in No protection is sought within the scope of the invention. After loading

A second groove 610 (Fig. 6, 7) is provided on the other in engagement with the bifurcated end 624, 626 of the shuttle 554 side. The groove 610 receiver 556 (FIG. 19), the carrier 544 acting with a rib 627 (FIG. 10) at the entry end of the receiver 556 exclusively in the one shown in FIG. 14 of the contactor box together and acts as a guide and 15 position shown is locked. When the shuttle 554 enters the shuttle 554 its way into the protective shuttle box. In addition, the top of the box 532 continues, the grippers 548, 552, standing under the load of weaving shuttle 554, slide an inclined surface of the springs 584, 586 over 612 (Fig. 4), which with the pick-up 556 or 557 the carrier 544, until its ends interact freely with the carrier 544 to give it to receive the carrier and its grip is released. It is known that the gers 544, as will be explained in more detail later, do not normally align the web shutters to exactly the same thing. The grippers 548 and 552 are normally followed in any movement by the springs 584, 586 of the sley 500 in the course of the sley 500, and therefore devices are urged in the closed position in which they hold the carrier to align the shuttle 554 with the 544, as shown in FIGS. 4, 6 and 7 can be seen, captured transducers 556 and for aligning the receptacles. When the receiver 556, 556 and the shuttle 554 come together, however, the carrier 554 engages in such a way that the carrier 544 engages precisely with the forked receiver 556 or 557 and becomes the end of the hooks 624, 626 of the transducer 556 occurs.

As one can see from the further devices, through the FIGS , 552 of the running shuttle, align the carrier 544 held on the right-hand side of the sley 500 with 40 zens as soon as one of the rails, forked at one end 616, enters the shuttle box 532. In 614, which is pivotable at its other end on this connection, it should be noted that a lug 618 is attached which extends from a spring 634 (Fig. 18, 19), one end of which in a rack 620 so that it extends over which lies a corresponding hole in the rack 620 of the sley 500. The tooth 45 and its other end in a bore in the rod 620 can sit within a gear box 622, rail 614 of the receiver 556, rigidly attached to the sley 500 freely longitudinally which is pressed to slide normally the bifurcated end sley. The extension 618 of the rack 620, 624, 626 of the rail 614 from the gear box 622 in FIG. 19 extends through a slot in the gear box 622 which extends in the longitudinal direction and which is fully shown in FIG. In this connection, it should be remembered that the rail 614 of the receiver 556 in the longitudinal direction is that the rail 614 is rotatably arranged on the sley 500 with the toothed rack 620 supported by the attachment 618. The contact who will. The way in which the rack 620 in the longitudinal rail 614 with the gear box 622 is used as a direction within its gear box 622 is actuated to limit the extreme position of the stop is to be explained in more detail later. 55 track 614.

stand from the selvage. The air jet is maintained until the shed closes again, so that the blown free end of the weft yarn 642 is held by the closed shed and can no longer slide out of the fabric. As soon as the sley 500 moves further backwards and the shed opens further, the shuttle 554 is driven over the sley by the picker 528 and picks up the carrier 544, so that the weft 642 sitting in it to the receiver 556 on the right Side of the loom is guided. The carrier 544 is received on the right-hand side of the loom at substantially the same point in time of the loom cycle as on the left-hand side of the loom; that is, as soon as the sley begins to move forward. The operating sequence is now repeated with the only exception that in this case the weft yarn 642 is cut off by the knife and the weft yarn 644 is cut off by the slide rail 560 of the carrier 544. By repeating these processes, the cloth is woven. The foregoing has described a weaving process using a single weft on each side of the loom. It will be understood by those skilled in the art that many colors can be provided on each side of the loom, provided that each color is fed by a separate aid from a separate supply spool or the like. Each color extends across the fabric and from a selvedge of the fabric to the feeder and, if one desires a particular color of weft yarn, all one has to do is operate the appropriate tool to pull the yarn into the end of the hook 560 'of the carrier 544 to be introduced.
