Needle loom. The subject of the present invention (l; ing forms a needle weaving chair in which, in a known manner, those from both sides of the chain or goods inserted in the compartment (church swinging catch or loop needles held weft thread loops by swinging bent at the free ends Entry needles are fed and at least one of these needle elements on the breast tree is appropriate.

The resulting great regularity of the aisle and the density of the goods is further supported by (On the one hand, leave the catch needles, which are expediently used to avoid Work thread breakage without influencing springs, in the longitudinal direction (leg goods, according to the movement of the drawer by means of an intermediate link or the like can and on the other hand the needles, which are bent forward in a known way, Swing out so briefly and quickly and in such a position that they stretch the Needles cannot get in the way and when the needles come in after your them Fast atisscliivingen given by a kind of curve guidance ini essential be kept still. As a result of the inclined position that results expediently of the entering needles becomes the tension spring connected to the insertion needles attached on its inside and causes in conjunction with one of the thread movement after each failure the following thread guide and with the support of the weft thread along the beak-like free lind of the needles entering the vach, who can insert the loops from opposite sides at the same time.

As can be seen from Elen's drawings, the loom is for simultaneous Weaving a relatively large number of narrow woven goods which can be either elastic or non-elastic depending on the R "un, with for each individual goods are each a pair of needles in a known manner, uni in the compartment formed by the warp threads, two loops of the wefts at the same time to be able to enter which of each pair of the loops capturing pins are maintained in position until the four loop layers of the weft of the on the drawer are recorded and posted. The needles are moved simultaneously in opposite directions around the two wefts to be placed in each compartment as soon as it is formed; accordingly are the two steel edges of the finished goods of a similar appearance. The needles are outside the edge warp threads on eitici- fixed 1 'uterlage or a bearer on a breast tree rotatably mounted and are moved by oppositely movable slides or the like, their movement by eccentrics or lifting disks arranged at one end of the loom goes out. In order to save space and in a relatively large number of the weaving . To produce goods or fabrics on a loom of a given length, it is advisable to the adjacent needles of two adjacent tissues on the same Axle to be mounted rotatably, and you can, if desired, the same pivot for use both needles. Each needle consists of a rotatable between its ends attached lever, the long arm of which has eyelets at its end for attaching the weft thread possesses, while the shorter lever arm with a slot. is provided, the for inclusion a pin or an attachment on a slide used to move the needles or the like. The two slides are arranged side by side and are proportionate narrow, so that they can possibly be attached in the same guide. Each pusher is used to move the needles of each pair.

The loop engaging pins for each pair of wefts are rotatably arranged on their supports and are grounded in their movements from to the fixed carrier located guides out. They are below as a whole placed at the level of the finished goods, where they are not in the way of your weaver. In As the reed moves forward, the pins are retracted or removed from the loops so as not to engage the path sheet. Each pair of these pins is mounted in arms which share a common hub or an aluminum sleeve, and the individual sleeves or hubs are adjustable a rocking shaft arranged by one located at the end of the loom Eccentric are moved.

The embodiment shown here as an example in particular has a chair frame that have any design and construction can. The frame is expediently arched or with hangers provided, on which devices can be arranged, for example, to the to store large bobbins or Kötzer i i for the weft threads. The weave style is with a drawer 12 is provided which has as much road leaves as woven goods are made nerds. The webs are separated from each other so that there are spaces between they remain, and the length of each individual path is slightly greater than the width of the \ Vare to be produced. The loading is made from the crankshaft 14 driven. Any suitable forming device, including the shafts 15, is used to hold the warp threads to form a smooth, patterned one Fantasy or pile ware o. (Hl. J e as desired. On the front of the loom is the usual chest tree "150, as well as suitable devices for winding up of the finished goods, the description of which is superfluous here.

The weft threads inserting the weft threads and the loop pins for grasping the 1-thread loops are arranged on the belt. For this purpose, a number of arms 16 are attached to the inside of the chest tree, which arms have essentially the shape shown in FIG. Are on their upper sides two fixed angeoranete, a guide free between transmitting guide rods 17 and 18, "moose in a substantially disposed parallel to the upper surface of the breast beam lying plane, and through which the finished product, such as from -6b. 3 can be seen being moved. On the rod or rail 17, the various pairs of needles entering weft are rotatably arranged, as indicated, for example, at ig and 2o. The needles rg are located above the rail 17 and the needles 20 directly below it. The adjacent needles rg and 20 of the two adjacent pairs are arranged on the same pivot pin -, i, which goes through the rail 17. By means of a screw 22 and washer 23 attached to each end of the pivot, the needles and pivot are kept in place. Each needle consists of a thin, flat handle a, which is curved to the right or left as required and is provided with two eyelets b at the ends. On each needle shaft there is a thicker part c with an annular collar surrounding the opening for the pivot pin. The part c protrudes from the pivot pin, has a slot d and extends at an angle to the right or left as required. The parts c belonging to the needles 2o have ends inclined to the left and are somewhat longer than the parts c of the needles ig. In order to move the needles of each pair in opposite directions at the same time, use is made of z, four slide rails 24, 25, which are relatively thin and narrow and are arranged in the space between the two guide rails 17, 18. The rail 2d. is with erect, zg entering the slots d of the needles Pins 2 () v. While the rail downwardly directed pins or lugs 27 load sits, which in the slots d of the Nadelft 20 enter. It can be seen that the Slots d of the needles with reference to the loading plane of movement of the two rails 24 and 25 are arranged at an angle so that a wedge effect on the walls of the slots exercised and the movement of the needles is accelerated. The two rails 24, 25 are like this (light on the pivot 2i for the Needles arranged that a relatively short longitudinal movement of the rails is agile, uni the needles around an arc to swing. which is necessary, uni the shot to enter the thread correctly in the compartment. As can be seen from Fig. 4, extend the Slide rails 24, 25 over the front frame on put an end to the loom and are with loving 28, 29 connected to that on one at this frame seated arm 30 rotatably are brought. Levers 2-8, 29 are with Rollers are provided, which in eccentric grooves in the outer surfaces of the lifting thumbs 31, 32 step which on the one from the front after the back of the chair through Sit shaft 33. This shaft rests in bearings 3.1, 35 and is equipped with a bevel gear 36 sclien, which with a corresponding Drive wheel 37 on the short shaft 38 in handle occurs and in turn from the one on the Crankshaft seated, thus engaging Gear 39 is driven. This tooth wheels are all in translation ratio i: i shown so that the shaft 33 itself for every rotation of the crankshaft once unidrelit. The eccentric grooves are so arranged in the lifting disks 31, 32, that the slide rods 24, 25 automatically after opposite directions are moved. If necessary, the slide rods 24, 25 by dividing it transversely into two parts disintegrate which differ from opposite Extend the sides of the chair inwards, in which case the levers 28, 29, the disks hen- 31, 32, the shafts 33 and 38 and the Gears 36, 37 and 39 on your other Be repeated at the end of the loom. If the drawer is moved forward so that the world sheet is in its extreme forward whose position b (-finds, as in _Xl) acc. ; Iar- is set, the needles are in the position shown in this figure, being approximately at right angles to the Slide rails 17 are directed. after the Charging returned and the compartment formed is, the needles are in the position of the Fig. 5 moves, with the shots entered and always a loop close to that At the end of the subject. From this Position the needles back into the Position of fig. (-) moved back, whereupon the (_a <le is moved forward in order to cast on the two thread loops of the two weft threads, as will be explained in detail later.

To prevent the loops of the wefts from being pulled back by the outward or severing movement of the needles, use of the loop-engaging pins which engage the wefts and hold the loops in place. Two of these pins, which can be seen at 350, are provided for each item to be woven. Each of these SS pins or needles "350 is straightened.

@t ie can be seen in Fig. 8 and is fixed in a gap block 360 rotatable on an arm 370 . The two arms 370, 370 consist of rods which are provided at their ends and which are screwed into openings of the hub 38o which have internal threads. These hubs are all arranged on a rocking shaft 39o, and each is split and provided with a clamping screw 4o to adjust it in the longitudinal direction and further to arrange it rotatably with respect to the rocking shaft, and is then locked in the desired position.

Each individual arm 370 can be inserted into a particular hub. do adjust it with respect to the other arm. tnn the device - to be able to use it for goods of different widths. In addition, in one embodiment, each Arin 370 can also be adjusted in the longitudinal direction with respect to its receiving sleeve and then secure it in its day by means of an adjusting screw 400. The rocking shaft 390 is supported in arms 16 and is provided at one end with a lever or lever 41 (see Fig. 10) which gives it the rocking motion - «arranged eccentric 42 and a lever 43 finite a roller 44 entering an eccentric groove in the outer surface of the eccentric 4.2. This lever is rotatably seated on a short shaft 45 and is rotatably connected to the arm 41 by an intermediate member 46. An am hrustbauin An internal guide arm 47 holds the lever 43 against lateral movement. The pins 350 are located directly on the outside or next to the edge chain threads and pass through guides 48 through which are fastened to the rail 17. In (lcr rest position As can be seen from Fig. 8, the:; needles below the surface @ lcit \ @ elnt-are: but when the shaft 390 is swung, the needles are straightened and pass through the loops of the weft threads h, as from the Ahb. 5 and 6 can be seen. They remain in this position when the needles are withdrawn from your shed, and as the ark and the reed on it move forward, the needles are gradually withdrawn and lowered into a position in which they are released As a result of their rotatable connection with the arms or supports 37o, the working ends of the needles receive a longitudinal movement with respect to the warp threads during the movement of the arms 370 about their axes, with the result that when the needles, As can be seen from Fig. 8, are in the rest position, their working ends come to rest in front of the front moving end of the reed; on the other hand, when the needles are advanced into their working position, their working ends move upwards behind the last weft threads, which in the goods have been struck firmly, and are in the position in which they grasp the weft threads, which from the needles in there s tray have been loaded.

From the above description it can be seen that one means a very simple device insert the weft threads in the shed and them in hold on to the same until the reed is able to to pound them into the end of the tray. By putting the needles on the outside the Sahlkanten located points rotatably attaches and their ends in the illustrated When bent over, it becomes necessary to move the needles around relatively short arcs, and one is thereby able to use slide rails, which directly with the needles are connected by a slot and pin connection. The longitudinal movements As noted earlier, the slide rails are relatively small.

In Fig. 3, the warp threads with the inclusion of the elastic and inelastic threads are denoted by e and shown in the position corresponding to the shedding. The weft threads, of which two are drawn, for example, are denoted finite f. They are drawn off, for example, by Kötzern ii and pass through a thread guiding device 5o, the details of which are not to be described here; but it should be noted that the device can be designed like a sheet in order to keep the weft threads apart. From the thread guide 50 the weft threads pass under the guide rail 51 and from there between the rods 13 of the reed and then below the guide rod 17 and 18 according to tensioning devices designated as a whole by 52. From there the weft threads go backwards and pass through eyelets attached to the resilient guides 53 and finally get into the eyelets b of the needles. The resilient guides 53, 53 consist of an elastic piece of wire, the free end of which is suitably rolled up to form a guide for the threads, while their other rolled end is fastened to the rod 17 by means of a screw 54. When the needles 1 and 9, 2o in and pass through one compartment, the guides 53 are resilient enough to as 5 can be seen, depending on the pressure exerted on the yarn train, as shown in Fig.5, against each other vibrate in Fig. To can. As soon as the needles move outwards or in the opposite direction from one another, the guides 53 also move outwards, uni the thread between the. # \, Aclelti and the tensioning devices straf z ;. draw. The resilient guides 53 therefore act not only as guides, but also as thread take-ups. Each of the tensioning devices 52 can be designed in any suitable manner. In the exemplary embodiment shown, however, the device has a sleeve 54 'which is mounted on the cylindrical rod 55 over which the finished fabric passes to the take-up roll. The sleeve 54 'is provided with an arm 56, from which a pin 57 protrudes laterally, on which the two conically shaped clamping devices 58 are attached. These sit loosely on the part 57, are rotatable thereon and are held against one another by a spring 59, which is located between one half of the device and an adjusting screw 6o which is adjustable on the threaded rod 57. As a result of this arrangement, the piece of weft thread located between the tensioning device and your Kötzer can be kept relatively taut by only pulling the thread through the tensioning device as required. Any decrease in tension that occurs here occurs only between the needles and the tensioning devices and is picked up by the guides of the receiving device 53.

When working with a chair of this type, the needles are in place in the position shown in Fig. 5, -when the drawer is in its rearmost position away from the breast tree. In this position the needles are, as can be seen, gone all the way through the weft and their ends are in front of the compartment. While a rotation of the crankshaft, starting from the just mentioned position of the needles, the loops engaging pins will begin to move upward have, further i @ cwegt so that they get into the loops of the weft enter. Then the needles containing the weft threads are in position the Ahb. <, while the pens that capture the loops are temporarily immobile stay and then begin your outward direction gracefully while the ark is forward emotional. While the ark has reached the front end of its movement, the the weft-detecting pins pulled out of the loops of the weft thread, and the "-eliliIatt has struck two loop layers of each weft thread, as can be seen from Fig. 7. As soon as the pins engaging the weft loops Let go of the Schtil.lschleife, the ends of the loops move a little inwards, so (let them be inside the outer edge warp threads and the loops in the finished product are not visible. The loops of the weft threads are entered in each compartment created by the imaging device so that accordingly there are four loop bends in each compartment and the goods are not produced this chair is done very quickly. The parts are all, as far as possible, so built and arranged. (Let sideways shaking movement of the chair prevented will. The needles are arranged in pairs. and move in opposite directions Directions, so (let the st () 13 of one movement compensate for the thrust of the other; the rails moving the needles are simultaneously in opposite directions moves, so that here too the impact of one movement compensates for that of the other can. The device is very simple. The H. eccentric for moving the needle rails and for putting the loops into operation the pins are on the same Shaft placed at the Kntle of the loom, and the movement of the various parts is thus brought into agreement. (Let the most desirable successes be achieved -will.

The arrangement of the tension devices love the needles is of great advantage, especially if they are used in conjunction with flexible thread take-ups used for those parts of the weft threads. which between the needles and the Tension devices lie.
