At least two fixed wefts ; - :, cn-jaws, one for jsdss UJobsrschif f, are on each ', cics verzusshsn, resulting in a minimum requirement of four packs to supply the weaver ships and at least four weft feeders, two on each side of the loom in order to feed the thread to the loomed looms.

,. The task of the innovation is to determine the number of weft packages and to reduce weft feeders needed to operate a loom that has an upper and a lower grapple weaver used.

According to the innovation, a loom in which the warp threads are divided into upper and lower sheds and an upper and lower rapier loom is shot through the upper and lower shed, respectively, characterized in that the upper and lower loom are simultaneously each of an opposite one. A. The lying side of the loom is shot to get through

move the upper or lower compartment and each weaver ship Weft thread is fed through a weft thread dispenser, the provided on each side of the loom and movable upwards is't "to" feed the upper loom and after can be moved below to supply the lower l'leberschiff.

The innovation is described in detail with reference to the accompanying drawings.

In the drawings mostly the loom in Fig. 1 for manufacturing won Fabric, e.g. velvet fabric, surface to surface including Carpets, a comb drawer 2 reciprocated by any device (not shown) for carrying out the Strike, which is formed with a longitudinal piece 4, a sheet 6 and a sheet cover or handrail 8. Warp thread run from a suitable supply through the sheet 6 to a Case 1 o of a fabric to be produced 12. These warp threads are § by suitably actuated (not shown) strands in upper, middle and lower panels 14, 16 and 1B, respectively, split to form an upper compartment 20 and a lower compartment 22. An upper one Greif er-UJeberschiff 24 and a lower Greif er-UJeberschif f 26 are shot in opposite directions, mac means that the weaver ships at the same time from opposite rides of the loom shot through the upper and lower compartments will. The upper weaver is supported by (not shown)

Firing devices alternately shot from the upper rifle box 28 a and 28 b, the lower lüeberschiff being shot equally from the lower rifle box 3o a and 3o b.

The gripper ships can be of any type. Appropriate ujeisa may be of the type described in our pending British Patent Application No. 8678/69

is described, in which the lüeberschiff has an elongated body which is formed with a recess in its upper side which contains a gripping device which can be opened in order to release a captured Sci'.ußräden when a side is down movable cam lever 32 (Fig. 2) protruding from the body is pushed inwardly of the body when the cam lever abuts one side of a contactor box. This gripper device contains two pairs of jaws which face each other and each pair

a stands from an upper cheek, which on one of its sides υοη a ■ cooperating lower jaw diuerges to a |

Provide thread-receiving gap between and the lower Jaw movable downward in response to inward movement of the cam lever and upwardly by a spring arrangement can return to the upper jaw.

Weft thread 34 and 36 υοη a yarn pack 34 a or 36 a is carried through each Uieberschiff on each side of the loom

tubular encoder eyelets 38 bzuj. 4o fed each to a Transmitter arm 42 (Fig. 3) are mounted which is screwed into a slide 44 which in a generally upright Tube 46 slides formed with elongated arm 42 receiving slots 48 and 5o. Through the Donor eyelets 38 or 4o υοη weft thread running upwards and downwards is raised by opening the slide 44 to feed yarn to the closed, upper UJeberschiff and ujird lowered by downward movement of the pusher 44 to feed yarn to the lower submarine. Each tube 46 is through a bracket 52 attached to an opposite side of the longitudinal piece 4 of the comb box 2. A sheath 54 of a pull rope 58 j-containing cable pushes into a on one side

\ the lower end of the tube 46 screwed closure 56 on. The

. Pull cord 58 runs freely through a passage in the lock

56 and through a passage in a screw 6o to one

j rope nipple 62, which engages on one side of the screw 6o, the

£ is screwed into a hole in the underside of the slide 44. A helical compression spring 64 surrounding the tension cable 58 presses on one side against a head of the screw 6o and on the other side against the closure 56. Another end 54a of the casing 54 (FIG. 4) is attached to a holder 66, which is mounted on a lower member 68 of the loom frame behind the comb drawer. The end of the pull rope 58 runs uon the end 54 a through a passage down into a

Screw 7o to a cable nipple 72 which abuts a screw head 74. The screw 7o is with a lock nut 76 screwed into a bolt 78, which can be pivoted in a fork-shaped bracket 8o is received, which is provided on a lower end of a lever arm 82 which schuienkbar at 84 on a fork-shaped bracket 86 is attached, which is held by an upper member 88 of the UJebstuhlrahmens. The lever arm 82 carries a rotatable cam follower 9o, which by the action of a tension spring 92 on the circumference a transducer cam 94 which is mounted on a rotationally driven half speed shaft 96 well known in the art is. When the encoder cam rotates, a peripheral part presses 94 a, the lever arm 82 to the left in Fig. 4 in order to exert a train on the pull cable 58, which in turn, the encoder eye 4o pulls against the action of the spring 62 into the lowered position in FIG. UIf the cam continues to rotate, join in Peripheral part 94 b in engagement with the cam töss el 9o, the arm swings back under the action of the spring 92 right, in order to relieve the tension cable 58 and thus to allow the spring 62 to expand and the eyelet 4o in the lifted Raise position zl. The extent of the lifting of the eyelet wi ^ d through the position of an adjustable stop 98 which is screwed into the upper end of the tube 46 is controlled. A similar Cable, lever and encoder cam assembly is provided to the

Raise and lower eyelet 3B, however, is the cam arranged offset by 18o with respect to the cam 94, so that consequently one transmitter eye is lifted and the other at the same time lowered.

Cutting knives 1oo and 1o2 for the weft thread are each attached next to an opposing ribbon of the loom 12 and are attached to a rail 1o4 which extends along the loom on its front side over a support plate 1o6. If SrrTitgeujebe is practiced, the rail 1o4 can be the well-known [Ylüßschiene for the pile height of the velvet fabric. Each cutter is of the type illustrated in Figures 5-7, which depicts cutter 100. The cutting knife usually has an upright front plate 1o8 with an elongated slot 11o in order to receive one or more bolts (not shown) which fasten the cutting knife to the rail 1o4. The front plate 1o8 holds a base plate 112 and two spaced apart, essentially parallel and upright side plates 114 and 116, which are each formed with a guide slot 118 to which a slide pin 12o is attached, which connects a freely rotatable wheel 122 with a Groove 124 carries. One end of the slide pin 12o runs freely through a knife arm ",?. & For the weft thread, which is formed with a nose 128 and a knife blade 13o for the

Weft thread with a cutting edge 132 picks up. This knife is outside the compartments and the cutting edge 132 points in the lateral direction of the loom away from the warp thread. A second pin 134 extending through the lower portions of plates 114 and 116 is attached to their front forehead lugs and passes freely through an L-shaped trimmer arm 136 for the bandage attached along plate 116 with an upper end 138 of trimmer arm 136 extends at the guide slot 118 i'Drbei. A lower branch of the arm 136 receives a generally vertical trimmer blade 14o for the sliver which extends through a slot 142 in the base plate 112 and has a knife blade 144 facing the rear of the loom. One extending downward on the Handle ^ ste 8 attached beater plate is arranged to hit the wheel 122 and push it (as shown in Fig. 5) towards the plate 1o8 when the comb box moves in the direction of the case 1o (Fig. 1) during weaving and 2) moved forward. This movement of the wheel drives the pin 12o forward in the direction of arrow A (Figs. 5 and 6) along the slots 118 and moves the arm 126 in the same direction, causing the tab 128 to be fixed on the side plate 114 To run up the pick-up block 148 and thus pivot the knife blade in the direction of arrow B over the weft thread

to lift, which is moved to the fall by the comb drawer ir μ "em (in the following with reference to Fig. 12-15 bssr- ri ..bsnsn). When the pin 12g moves forward, a roller 15o on it hits the end 138 of the arm 136, which swivels in order to swing the trimmer blade 14o for the Salband upwards in the direction of the arrow H into the position shown in FIG

* labeled attached to the ribbon. Accordingly, that cuts

Swinging the blade 14o upwards into the ribbon woven wefts to trim a strip 152 (Fig. 1) thereof and a pleasing edge of the on the fabric Leave 12 remaining ointment. To ensure that this remaining ointment is firm, it is preferred that the Form ligaments through a Linon-llJebart by the Warp thread of the ointment during weaving a linon movement is granted. A down from the base plate 112

Extending bolt 154 may be provided adjacent to blade 14o

to deflect the strip 152 from the main portion of the fabric. Another down from plate 112 extending bolt 156 may be provided to the Deflect the warp threads from the knife blade 13o for the weft thread. When the comb drawer returns rearward, the striking plate 146 disengages from the wheel 122. The pin 12o then returns through the Action of a return spring 158 surrounding the pin 134 along the

- 11 -

Slits 118 back, the return spring 158 having legs 158 a and 158 which press against the groove 124 or against the base plate 112. The return of the Gieitstiftes 12ü lowers the knife blade 13o in a substantially vertical position at a small distance from the case where the blade is held by a ^r Eder 16o against accidental upward displacement. The trimmer blade 14o is lowered by a return spring 162 surrounding the pin 134, which has a leg 162 a tensioned against the base plate and another leg 162 b which is hooked into the cutting arm 136 for the bandage.

A curved protective plate 1o1 is arranged over each cutting knife 1oo and 1o2 = the protective plate 1o1 can for example be made of a clear plastic material and is pivotally mounted on a rod1o3 which extends over the Rail 1o4 is arranged. The edges of the protective plate 1o1 are attached in grooves in blocks 1o5, which are on the head rail 3 are attached, these blocks 1o5 slide along the edges of the protective plate 1o1 when the comb drawer back and forth moved here.

From the yarn pack 34 a or 36 a yarn runs through one Tensioner 164 or 166 before it reaches the encoder eye 38 or 4o. Each tensioner is the same, illustrated in Figures 9 and 10

Design and is reversed L-shaped with a support Cross-section formed, which is fixedly attached to the loom by bolts 1 7 ο or the like (Fig = 11) is replaced. Correctly enough, this can be a double cam each with a general teardrop shape, ujobei their lugs 192 a are arranged offset from one another by essentially 18o are. The tensioner arm 174 is raised when one of the noses 192 a touches the cam follower and is lowered, ujenn Peripheral parts 192 b of the tensioner cam 192 touch the cam follower. The tensioner arm 174 therefore turns per revolution the H. ^ lbgeschtuindigkaitainlle raised and lowered twice.

A triangular-shaped weft thread guide ader eyelet 194 from the Example wire is attached to arm 174, by itself one vertex of the triangle extends downwards. UJenn der When the tensioner arm is lowered, the eyelet 194 is between a pair of stationary, hollow, open, conical-shaped

• Thread guides 196 on the 19o side of the carrier ι

are attached, with the cone tips facing each other.

A pair of guide plates 198 for the weft thread from the Example porcelain is between the stationary storage packs arranged for the weft thread and the eyelet 194. Both guides 198 are free at internal centers on a spindle 2oo fastened, which is fastened on the side 19o. A leadership position is by an excessively strong coil spring 2o2

- 13 -

pressed against the other, which hits a fixed stop 2o4 on the spindle . The spring pressure is such that the weft thread is almost pinched by the guide plate 198 in order to prevent the thread from being pulled by the package when the eye 194 is raised by the arm 174. When the arm 174 is lowered, a beveled end 2o6 of a hook-shaped bolt 2o8 fastened on the arm 174 is pressed between the guide plates 198 in order to separate them from one another and to release the thread. The thread is also passed through known guide eyes 21r and another pair of guide lugs 212, one of the plates being pressed onto the other by a spring.

The guides 194 and 196 are with diuerging sides designed to deflect the weft and prevent it from moving around these guides and the tensioner arm To tangle, sudden raising and lowering of guide 194 should cause swaying of the line.

Another tensioner cam, hinge, and cable arrangement actuates the arm 174 in the tensioner 164 and in this case the cam is arranged in the same position as the cam of the Tensioner 166 so that both tensioner arms 174 are raised and lowered simultaneously.

- 14 -

The raising and lowering of the donor loops 38 and 4o and the Tensioner arms 174 are with the shooting of UJeberschiffe 24 and 26 and the flapping of the comb drawer 2 coordinated, to produce a sequence shown in Figs. 12-15, in which, for the sake of clarity, only the lower web 18 of the warp threads and the lYlesser blade of the cutting knife are shown

1
1o2 is denoted by 13o in order to distinguish it from the lYlesserkinge 13o of the cutting knife 1oo.

In Fig. 12, the comb chest 2 is in the rear position, the upper UJeberschiff 24 and the lower UJeberschiff 26 are in the upper and lower contactor box 28 a and 3o b and the encoder eyes 38 and 4o are in the upscale bztu. lowered position. Eeide Tensioner arms 174 are lowered, with the bolts 208 on them holding the guide plates 198 apart.

The grabber-submarines are simultaneously uon opposite Sides of the loom shot and when passing the donor eyes, the upper UJeberschiff 24 grasps the weft thread 34 and the lower one UJeberschiff grasps the weft thread 36. The weft thread 34 is carried in the upper compartment and the weft thread 36 in the lower one Academic subject. A section of the stretch from UJeberschiff 24 to the Salband of the fabric 12 extending weft thread 34 thus counteracts

1
the lyless blade 13o is pulled and severed, while the weft thread 36 is equally severed by the riless blade 13o. The state shown in FIG. 13 has now been reached.

- 15 -

On opposite sides of the loom, the Uieberschiffe 24 and 26 enter the upper and lower gun boxes 2S b and 3o a, ω ir in Fig. 14 dargRf3tRl.lt, and release the weft threads, which by the forward movement the comb tray 2 can be moved in the direction of the case 1o. When the comb tray 2 moves, the Tensioner arms 174 are raised simultaneously and pull portions of the weft threads between the conical guides 196 across to the general direction of movement of the thread upwards. This upward movement of the A.me 174 triggers the guide plate 198, which grasp the weft threads, so that the train of the tensioner arms 174 a longitudinal pull in the weft threads used last back through the compartment over a certain distance, to be drawn during the forward movement of the sheet 6 s hit f and the length of the loose ends protruding from the ointment bands to decrease the weft threads. This tightening of the wefts results in a more tightly woven fabric that is more pleasing Look. When the ca'im drawer 2 has reached the case 1o, the filess blades 13o, indicated in dashed lines

1
and 13o raised to avoid the weft threads which run underneath. The trimmer blades 14o described with reference to Figures 5-8 are also raised to trim the sash bands by cutting through the weft threads previously woven into the sash bands.

- 16 -

The switching of the warp thread now takes place and the comb drawer moves n. <ch behind. This allows the knife blades

1
13o, 13a to fall off, ujie shown in Fig. 15, and hook behind the portions of the weft threads 34 and 36 r) which extend from the ointments to the loops 38 and 4o, which now move into the lowered and raised position, respectively, then the arms 174 are lowered and push the guide plates 198 apart. The state is now essentially the same as that shown in FIG. 12, except that the transept 26 will pull the weft thread 34 through the lower shed on the next shot and the weft thread 36 is inserted through the weaving ship 24 into the upper shed.

A big advantage of the above with reference to the drawings described loom is that the same encoder can be used on each side of the loom to both To supply over-ships with thread from the same pack.

If desired, weft threads of various materials, Colors, qualities, etc. on one or both sides of the Loom are provided, each thread having its own encoder, which can supply both Uieberschiffe, but also has a movement that the feeding of a
