Description

Circular knitting machine The invention relates to a circular knitting machine with a needle circle and with a device that works with the needles for the purpose of forming the loops, which a device for feeding a main thread to the needles and a device for feeding an auxiliary thread only to certain Needles and a clamping and cutting device for the main thread and a special one Has clamping and cutting device for the auxiliary thread.

For circular knitting machines it has already become known, special Provide clamping and cutting devices for the auxiliary thread so that this auxiliary . or reinforcement thread clamped and i can be cut off. This took place clamping and cutting this auxiliary thread at a time when he except Effect has been taken.

It is also already known the thread cutting and clamping devices to let work outside the needle ring, if there is space inside this ring is no longer free, a needle disk was arranged above the needle cylinder. With these well-known. Machines are the clamping and cutting devices by controlled by special fingers that are operated from the sample drum. At a A circular knitting machine is such a sample drum for the production of a stocking rotated intermittently by individual steps, but does not serve to. the introduction and To bring about removal of a thread while forming individual courses. So when working with these known machines, a thread is put into the machine introduced and then remains over a large number of courses, in progress, whereupon it is removed. Such a large number of courses can, for example to produce the length of a stocking.be-, used, and the thread can thereafter removed during the formation of the heel.

Finally, it is also belianntgewor, a clamping and cutting device where an auxiliary or reinforcing thread is inserted in each row of stitches and should be cut off. It has also already been proposed that the device to arrange the reinforcement threads outside of the needle roller and cage assembly, so that the reinforcement thread is kept outside the needle rim for any length of time can be.

According to the invention, one comes close to the needle circle Part, such as a tongue ring, for use in order to be determined beforehand Times the Take up auxiliary or reinforcement thread, so be accidental engagement with the needles is avoided. This tongue ring is here according to the invention finite a slot serving to receive the auxiliary thread Mistake. In the embodiment of the In accordance with the invention, the machine has a device to reduce the slack in the thread take up, this device has the consequence that the thread in the to his Recording certain slot of the tongue ring occurs.

Preferably here is between the receiving device and the A tension device attached to the auxiliary thread supply, which holds the thread during the Entangling releases. The arrangement according to the invention is particularly suitable for Circular knitting machines with thread guides.

The machine shown, which is a machine with a rotating needle cylinder is, has an elongated cylinder 2, dmeir around an upright axis is rotatable and provided with longitudinal slots which slidably hold the needles 6, which have feet 8 of different lengths, as well as intermediate pushers io, which likewise are provided with feet 12, and lower pusher 14 accommodate which with removable Feet 16 are provided and have strips 18 at their lower end. The needles and the intermediate pushers slide in a vertical direction in said slots, and the needles are held in these slots by the usual spring straps, while the intermediate pushers in the slots by engaging the cylindrical Surfaces are held by certain control parts. The lower pusher 14. slide and vibrate in vertical radial planes around points between the upper ones and lower ends of these pusher lie. For this purpose the bottom pushrods are formed on their inner cages in such a way that a point 19 is present is, around which the bumpers can swing when they are acted on by control units. The lower The pusher is held in place by a single spring strap that you click on but does not rely to keep the pusher in a certain position when this spring band also has the tendency to hold the pusher so that its lower Ends protrude outwards.

The usual gear 2o is attached to the needle cylinder, which is driven by means of an idle wheel through the spur gear 5o, which is controlled by a suitable device of a type known per se, in order to perform both orbital movements as well as to induce back and forth movements. The wheel 2o is in the part 2z of the frame stored.

To provide a support for the individual parts of the device, a plate 24 is provided, which from the lower part 22, of the frame by suitable Post is worn. A bearing block 26 supported by the plate 24 carries a shaft 28 (Fig. i), on ″ on which a bearing arm 30 is pivotably mounted; the latter wears a ring 3z. There is a hook on the front part of the bearing arm 34 hinged, which engages with a pin 36 of an upright standing bearing arm 38 is carried around said ring in its lower position to keep. By moving the hook 34, the latter is released from its pin 36, whereby the ring can be lifted up in the usual way. A suitable one The spring serves to balance the weight of the ring and keep it in the open Able to hold. The usual control ring 4o, which controls the actuation of the Has circuit boards is used; this control ring has the usual play, to allow vibratory movements caused by the engagement of stops be limited with the post 38.

A bearing block 42, which is pivotable on the shaft 28, is on his the front end is provided with a downwardly projecting part 44 which has openings, pass through the head screws 46 which are screwed into the bearing arm 3o are (Fig. 2). A spring 47 keeps the weight of the bearing block 42 in balance, so that the latter seeks to remain in the position shown in FIG. when it is held in its lower position by the screws 46. When he's through these screws is attached to the tongue ring, said ring and the Pedestal can be raised as a unit by pulling the hook 34 off the pin 3 6 solves. The bearing block is in its raised position and 'is the tongue ring alone in the working position, a smooth knitted fabric can be produced, while, when the bearing block 42 and the parts carried by it are also in the lower Laying threads around the needles to create patterns occurs.

The shaft 48, which carries the gear 50 , which in turn drives the wheel 2o by means of an idle wheel, protrudes upwards and carries at its upper end a gear 52 (FIG. I) which in turn meshes with a gear 54; the shaft of this gear 54 has a universal joint connection with one part 56 of a split shaft on which the other part 58 sits by means of a tongue and groove. The upper part 58 has a universal connection with the shaft which carries a gear wheel 6o and which is mounted in the bearing block 42. The gearwheel 6o meshes with a gearwheel 62 which is attached to the part 64 carrying the folding thread guides.

The part 64 has a plate 66 which is provided with support pins 68 on which the coils 70 sit. A plate 74, which serves as a carrier for the tubes 72, is attached above these coils 70. The plate 74 has bores through which the tubes extend and which are held in place by nuts. Each of these tubes (Fig. 3) carries at its outer end a resilient tension member 76, the upper arm of which rests on the upper end of the tube in order to tension the thread which passes between said arm and the tube. Thread guide tubes 78 extend through part 64 and protrude below the parts (FIG. 9) which feed the threads to the eyes of the folding thread guides 8o. These thread guides 8o are carried by a head which constitutes the lower part of the device and which preferably consists of a single part comprising cylinders 82 and 83 which have vertical slots in alignment; a groove is provided between said cylinders, which has a semicircular, radial cross section in order to receive the semicircular projections 86 on the folding thread guide and thus to provide a support point for these thread guides. The weft fingers are held in said slots 82, 83 by a spring band 88.

The threads from the bobbins 70 run up through the bores in the tubes 72 (Fig. 2), then under the springs 76, so that the springs are stretched, and then down through the tubes 78 and finally through the eye of the thread guide. The lower ends of the thread guides are twisted in the usual way, so that when the thread guide is through the needle circle liin- "through moved outwards, he on one side of the needle passes with which he as a result of the controlling action of the hook at deal end the needle cooperates, and then on its return movement due to the control action of the needle hook passes on the other side of the needle.

The thread guides are provided with feet 9o at their upper ends, which occupy two different positions in the present machine; on the Feet acts in the upper position of the control arm 92, while in the lower position the feet of the control arm 94 acts. These control arms are on an upright standing Pins 96 are pivotably mounted and are guided by the feet of the thread guide Springs 98 forced away; the limit position is determined by suitable stops. The different feet go to the. Thread guides ensure the possibility of a larger pattern change, since by controlling the control arms 92, 94 fingers Can optionally be selected to be independent of the selected uplift of the needles to be effective or ineffective. It can of course also be a larger number of feet with a corresponding number of control arms similar to arms 92 or 94 may be provided.

To control the action of the control arms 92, 94, the latter are with Projections ioo (Fig. Io) are provided, which are detected by the control levers 1o2, 104 «-Earths, which are pivoted at 1o6 and on the upright levers 1o8, i io act (Fig. 9). Springs 115 hold these levers 102, io4 in such a way Position that they act on the projections ioo so that the control arms 92, 94 are in the correct position to act on the feet go, reducing the lower Ends of the thread guides are moved outwards. The return movement of the thread guides, such that their lower ends are moved inwardly with respect to the needle circle, becomes by the action of the edge 113 of a control part 112 all places below the bearing pin 86 brought about.

The levers io8, i io are at i i i on your upright post l07 pivotally mounted, and the levers 114, 116 act on their lower ends from the former from the upright tube i 18 that goes into the machine frame is supported, while the latter is supported by a shaft 120 which lies within the tube 118. The tube 118 is at its lower end provided with a lever 122 on which a control part 123 acts, that of the control drum 126 is carried, while the shaft 120 carries a lever 12.4 on which a control part 125 of said control drum acts. When the levers 122, 124 by their associated Control members 123, 125 are swung outward, so they cause the Lever 1o8, i io move levers 1o2, 1o4 against the action of springs ii5 and thus have the consequence that the latter out of engagement 'with the associated control arms 92, 94 come. The action of the springs 115 on the other hand has the consequence that the control parts 92, 94 move inward and act on the feet 9o. The control arms 92, 94 (Fig. 2) are carried by the pedestal 42 so that when the latter is lifted the arms will be lifted up.

The bearing block 42 is kept steady in its operative position in that a conical bore in the shoulder 130 engages a conical pin 128 which protrudes from the upper end of the post 107. A leaf spring 132 (Fig. 2) which is fully supported by the lug 130 is provided with an opening which engages over the pin 134 which is fully supported by the post 107 so that a freely movable latch is formed around the pedestal to hold in its lower position before it comes into contact with the screws 46.

In Fig.17 a development of the lock and control parts is shown, which act on the feet on the needles and on the plungers. Since only one yarn feed point is provided, only one lock or a single set of lock parts is present at this feed point. This lock has an upper lock part 136, a lower lock part 138 and the side triangles i4o, 142 and the end lock parts 161, 163 together with the usual lock parts which are combined with the latter in order to move the needles in the correct manner for the purpose of forming the loops . The side triangles 40, 142 sit on slides of conventional design (not shown) so that the needles can be brought to the same hell. In order to enable the production of gusset tips, lock parts 144, 146, 148 are provided on one side of the feed point, while lock parts 150, 152 are provided on the other side of the feed point. The lock parts 144, 146 are carried together by a single support member, the lock part 144 only cooperating with the long feet, while the lock part 1q.8 can grasp both the middle and the long feet of the needles. A channel 145 for the needle feet is provided between the lock parts 144, 146. The cam part 148 serves to lift only the needles with long feet, while it lets out needles with short feet and middle feet. These lock parts can be moved inwards and outwards, as will be explained in more detail below. The lock parts 15o, 152 not only work for the purpose of producing gussets, but also perform the function of the usual switch triangles. The end lock part 116 is a somewhat unusual distance away from the side triangle 140 and leaves a space 159 free through which the feet can move in a deeper plane. This is done in order to take into account the cutting and clamping device for the reinforcing sole thread (double sole thread), the said device, when it is in effect, protruding over the needle circle.

A lowering driver or increasing finger 154 and a lifting one Drivers or minor fingers 156, 158 of conventional design are also provided.

Below the individual lock parts described is a continuous one Ring of control parts 16o (Fig.id) available, which serves to the intermediate ram 1o to keep within the slots of the needle circle. The surface of these control parts, which form the ring 16o sees the usual end control parts 161, 163 for the needle feet before. There is also a control surface 162 on the lower part of the ring 16o, to act on the feet 12 of the intermediate pushers 1o; this control surface has 162 to the other control parts a position that emerges from FIGS. 17 and 2o.

The angular position between the needle lock parts and the control parts the actuation of the thread guides can also be seen in FIGS. 17 and 20; the parts 92, 9q described above. and 112 take their effective positions a.

A control part 164 can be mounted on the shoulders 18 of the lower pushers 14 act. The effective area of this control part 164 is shown at 166, which indicates the height to which the shoulders i8 are raised. A beveled one upper projection 168 on this control part serves to lower the lower ends of the lower Move the push rod inwards, thereby releasing the shoulders 18 from the control parts after the pusher for the purpose of cooperation with the transfer thread guides in their highest position have been raised. Those pusher whose lower ends previously have been moved inward are not detected by the control part 164; the others slide onto the control part 218 and then onto the control parts 164 to 166, the control members 218 and 164 being separated for convenient adjustment are trained. A safety control part 172 prevents those from overflowing Pushers which have been depressed by the control part 162. This control part serves here to keep the pusher in a position to be followed by the control part 174, which has an independently sloping surface 176, which in turn serves to engage the shoulders 18 step and align the pusher so that the feet 16 attached to it are in the required position Work together with the individual levers 18o, 182.

A safety bevel 170 prevents the control part from breaking the feet: 218 during backhand knitting. A suitable control member, not shown, holds the lower ends of the pushers inward until they are swung out by the control member 178 which serves to swing the lower ends of the pushers outward prior to actuation of the levers 18o (FIG. 16).

From Fig. 5 it can be seen that the lock parts 14q., 146 by a lever 184 are supported, which is pivotally mounted on the frame at 186 and the Inward movement is limited by a suitable adjusting screw, which with a fixed part of the machine comes into engagement. The lever 184 carries a pin 188, which engages with a fork that is formed on an angle lever igo which is pivotably mounted on the frame at 1g1. A spring 189 presses move the igo lever in a direction opposite to that of the clock. A handlebar -192 connects one arm of the lever igo with a lever 194, which is of a Shaft 196 of a set of hollow shafts is carried in upright bearings rest and sit together. The lower end of the shaft 196 carries a lever 198, act on the appropriate control parts zoo carried by the control drum 126 will.

The lock part 15o, the position of which is best shown in FIGS. 17 and 2o can be seen, is carried vori a piston 2o2 (Fig. 5), while the lock part 152 in a similar manner from. a piston 204 is supported. These pistons that slidable in the radial direction in a frame attachment and prevented from rotating are, become common by suitable springs, not shown pushed outwards. Control parts -2o6 and 2o8, which are best shown in Fig. 2, act on pistons 2o2 and 2o4 to move the latter inward at the appropriate time. These control parts are carried by the upper end of the posts, which on a hopf 21o are attached, which is usually pressed by a spring 212 downwards is engaged to either a lug 21d1 carried by the head with the surface of the main control disk or in contact with suitable ones seated on it Bring control parts 216. The control parts 2o6, 208 are on their support posts adjustable in the vertical direction, so that the timing of the lock parts 15o, 152 can be conveniently regulated during their inward or outward movements.

The control part 16.1 (Fig. 7 and 7a) is carried by a block 218, which can be adjusted with respect to the control part by means of suitable adjusting screws 22o is. The block 218 is carried by a slide 2.22, which in the radial direction is adjustable in the lower bracket of the frame; the detection of this slide in the set position takes place by clamping a screw that is held by a elongated slot of the slide passes and engages in the bearing block.

The control part 178, the effective part of which is indicated in FIGS. 17 and 20, has the shape of a lever which is articulated on a stationary, upright post 223 . The arm of the lever 178, which lies opposite the active end, is adjustably fastened to an arm 226 by means of a clamping screw 2a4, through which an adjustable set screw 228 is screwed (FIG. 6), which rests on the hub of the lever 1 78 . Since the screw 22: 1 is a clamping screw, the lever 226 forms an extension of the lever 228, so that in reality a single lever comes into engagement with the handlebar 230. The arrangement described has the purpose of providing a fine adjustment of the inner radial position of the effective end of the lever 178. By loosening the clamping screw 22q. For example, the arm 226 can be swung out with respect to the lever 178 until the set screw 228 abuts the hub of the lever 178 in its correct set position. When this correct position is reached, the clamping screw 22.1 is tightened. A spring 231 presses the lever 178 in the clockwise direction. In order to counteract this spring and bring the operative end of the lever 178 in a position to engage the pushers 14, the link 23o connects the lever 226 to an arm 232 which is supported by one, 231, of a series of nested sleeves will be carried; the lower end of this sleeve 234 carries an arm 236 which can be grasped by the control part 238 on the control drum 126 «can be grounded.

As already mentioned, a set of control levers i 8o, 182 is provided, the lowest of which is labeled 1.82, especially since it has different functions and has connections than the others. This lever is controlled by a handlebar 240 (Fig. 6) with an arm 2,42 of another tubular socket of the mentioned socket set connected, which carries at its lower end a lever 244 on which a control part 246 of the main control disk 126 acts.

Springs 2.18, which comprise an upright stationary shaft, are attached at their ends to the individual control members 18o to the left of the journal 223 (FIG. 6), so that they usually influence these control members so that their effective ends inwardly and in engagement be guided with the feet 16 of the pusher 14. The various control members 18o are provided with projections which engage the feet of pins carried by a pin wheel 250 ; the latter is of the usual type and has pins, the feet of which are broken away as desired in accordance with the desired patterns to be produced. The wheel 25o is provided with a series of ratchet teeth 252 which, with the exception of one tooth 254, extend the full amount radially outward. A pawl 256 acts on the ratchet teeth 252, 254 and is pressed inward by a spring 257 and carried by a lever 258 (FIG. 6); the latter is connected by a link 26o to the upwardly extending arm of an angle lever 262, the other arm of which engages tabs 264 which are present on a pattern chain 266 which in turn goes around a sprocket 268 which is stepped through in the usual manner Engaging is moved with a pawl which is attached to a swinging pawl 27o, which receives an oscillating movement with each revolution of the needle cylinder. A cover or protective member 272 is hinged on the skin of the wheel 25o. This protective member is in the form of a plate with the outer edge tapering off in a series of steps 27-1, 276 and 278. If step 27: 1 is opposite the region of the effective end of pawl 256, that pawl will engage all teeth including tooth 254 so that its reciprocating motion gives wheel 25o a step. On the other hand, if the step 276 is opposite the free end of the pawl, the pawl is held outwardly such that while it is engaged with the full size teeth 252 it will omit the shorter tooth 254. Thus, if step 276 cooperates with the pawl, as long as the ratchet wheel is operating, wheel 25o will also be incrementally rotated until tooth 254 is able to be gripped by the pawl. If this occurs, the pawl moves back and forth ineffectively, while the wheel 25o stops in a fixed position. When the outermost step 278 (Fig. 8) is brought into engagement with the pawl 256, no tooth will be detected and the pawl will ineffectively reciprocate without imparting 250 movement to the speech.

The protective plate 272 is supported by a handlebar 28o with a lever 282 (Fig: 6 and 8) connected, in turn by a handlebar 2284 with an Arrri 286, which of the outermost tubular sleeve of the nested Sleeve is carried, which at its lower end carries an arm 288, which comes into engagement with a control part 29o which is adapted to the guard plate 272 holds in its various positions.

The projections on the control levers 18o, which are engaged by the feet on the pin spine 250 , are to the left of the post 223 (FIG. 6). The engagement of a foot with one of the control levers 18o will thus cause an outward movement of its operative end, so that it leaves the associated foot 16 of a pusher 14 out. It is desirable to have the outward movement of the operative ends of the levers 18o by the feet on the pin spout as well as by other means so that greater variety in patterning can be achieved. For this purpose, three levers 292, 294, 296 (FIG. 2) are positioned vertically one above the other. pivotally mounted on an upright post and moved in the clockwise direction (as viewed in plan view) by springs 298. Each of these levers is provided with a protrusion of substantial vertical extent for engaging the tails of a plurality of control levers. However, this protrusion on the lifter 1296 does not engage the control lever 182, although it may engage a plurality of control levers 18o immediately above it. Even if only three such levers are indicated in the drawing, more or fewer of them can also be provided.

The levers 292, 294 and 296 are connected by links 300 to arms 302, 304, 306 which are attached to three of the nested flutes which form the above-identified group of shafts. The lower ends of said shafts carry arrrie 308, 31o and 3r2 which engage control members 3I4 3I6 and 3z8 carried by the sample drum 126 . By influencing these various levers 29: 2, 294, 296 through the intermediary of the aforementioned control parts, the corresponding groups of the individual control levers 18o are caused to leave the feet 16 on the pushers 14 regardless of the setting of the pin wheel 25o.

In FIGS. 11 to 15, the devices for changing and feeding the yarn are shown. The yarn feed device and the devices for cutting and presenting are designed in such a way that a disruptive engagement of the main threads and their cutting and clamping devices with the folding threads is avoided. They are of a known type per se and therefore do not need to be explained in more detail, except with reference to the modification by means of which a correct cooperation with the feed device for the double-sole thread and the clamping and cutting device is made possible. In Fig. 13 there are two thread guides 32o, 322 which are pivotable about a pin 334 and are arranged so that they can be raised and lowered by known means. The thread guide 32o is provided with a plurality of eyes so that a corresponding plurality of threads can be fed to the needles in the clad position. A hook 324 and a press 326 act to guide the threads from the thread guides initially across the needle circle so that they can be grasped at the right time when a thread change is to take place. A stationary blade 328 cooperates with a movable blade 330 to cut the main thread, while a clamp 332 in the form of a flexible plate is placed on the movable blade 330 and serves to clamp the main threads after they have been severed.

On the stationary shaft 334 the thread guide 336 for feeding the double-sole thread is pivotably mounted, which lies next to the main thread guides 320, 322 and is provided with an attachment 338 which is grasped by the upper end of a lever 34o which carries a roller 3.12, which in turn comes into engagement with a control cam 344 during the rotation of the needle cylinder, which in turn is carried by the revolving sinker ring. The engagement of the roller 342 with the control part 344 serves to raise the thread guide 366 out of position when the needles which the upper part of the foot A spring, which is indicated in Fig. 4 at 343, usually presses this double-sole thread guide down into the operative position.

During the formation of those parts of a stocking that do not require the double-sole thread, it is necessary to leave the thread guide in its ineffective upper position without. Keep in mind the continued rotation of the control member 344. For this purpose, the inner end of the lever 3.16 engages under the thread guide 336, and the lever 346 carries an adjustable stop screw 3.18 which is gripped by the upper end of a piston 35o which extends through the machine frame (FIG. 4) extends below and is in engagement with suitable control parts of the main control disk.

Since the double-soled thread has to be cut and tightened during each revolution of the needle cylinder, it is evident that the main cutting and fastening device is insufficient for the correct action on the double-soled thread. Accordingly, a special cutting and clamping device is provided. This cutting and clamping device is arranged so that it can be moved away by the needle cylinder at the right time to prevent the needles from interfering with the loop formation. For this purpose, a lever 352 is pivotably mounted on the upper bearing arm at 35.1 and is pressed by a spring 356 in a direction opposite to the clockwise direction (as seen in the plan view). A link 358 connects the lever 352 to an arm 36o carried by the solid inner shaft 362 of the aforementioned shaft set; the shaft 362 is provided at its lower end with a finite arm 36.4 which engages finitely suitable control parts 366 on the drum 126. A type of bearing '368 is attached to the inner end of the I-lever 352, on which a horizontal pin 370 can be pivoted an angle lever 372 , which at its inner end carries a driven part 37.4 which finitely supports the control parts 376, 37.9 in Intervention comes - which are attached to your sinker ring, so that they turn with the latter during the rotation of the needle cylinder. An adjustable stop 38o attached to the upper end of the angled lever 372 (Fig. Ii) is arranged to engage devices which govern the clamping and cutting devices so that the latter occurs with each revolution of the needle cylinder being affected.

Hinged to the stationary post 382 carried by the bearing arm 368 is the hub 384 of a supporting bearing arm 386 which is moved by a spring 388 in a counterclockwise direction (when viewed in plan) to engage an adjustable stop screw 390 in FIG Engage a post 392 attached to support arm 368. The clamping and cutting device (FIGS. Ii and 12) has three stationary blades 394, 396, 398. A clamping sheet 4oo, which has an inner, L-shaped end, goes back and forth between sheets 39.1 and 396, so that it grips the double-sole thread feed from your thread guide 336. Between the blades 396 and 398 there is a knife blade 402 which cooperates with one of the stationary blades, which works as a stationary knife in order to cut the thread. The sheet 402 is L-shaped at its inner end. Sheets 4oo and .402. which together can slide, are provided with feet 404 at their outer ends; these feet enter a slot of a slide .1o6, which is pressed outwards by a spring 408 to bring its outer end 410 into engagement with the stop 380. When the spring .408 moves the leaves .40o and 402 outward, it seeks to cut and clamp the double-soled thread. The inward movement of the stop 380 as a result of the action of the control parts 376, 378 on the driven part 374 releases the thread and moves the sheets into their open position. As will be explained in more detail below, one of the movements mentioned is caused by the control part 376 . an ineffective one, especially since the double-sole thread is then caught by its cutting and Kletnniglieder. The light spring 112 serves here to keep the stop 380 in engagement with the end 4io of the slide in order to keep the latter under control. This spring is lighter than the spring 408 and does not prevent it. that the spring 408 urges the slide outwards. It is important that the double-sole thread is controlled so that if it is not knitted it will not be caught by the needles. In order to avoid an accidental engagement of loose thread loops of this thread with the needles, an inclined undercut slot 414 of the shape shown in FIGS. 12, 13 and 14 is provided in the inner surface of the ring 3a, in which the sole thread lies when the thread guide 336 is out of action, the end of this double-sole thread being clamped in the cutting and clamping device. Instead of using an undercut slot, as shown at 414, which has a relatively limited depth, a slot can also be provided, which is shown in FIG and is attached to one side of a cut-away part. This plate naturally forms a flat extension of the: a surface of the ring and is actually a part of it. The plate was made as a special part only for the purpose of simple construction and formation of a deep slot.

To further ensure that the double-sole thread does not loop ejects that at an undesirable time approximately from. the needles is detected a thread tensioning and take-up device is provided (Fig. 4, 5, 18 and ig). These Device has a lever 42o that sits on shaft 362, which, like Explained above, the lever 36o carries, which in turn moves the arm 352 granted. A pin 422 extends upward from the arm 4.2o and is arranged so that it can engage the lower part of a tension disk 424, around the latter from a stationary disk 426, which is from a stationary part of the Frame 428 is carried away when lever 420 is in the clockwise direction (seen in plan view) swings out. If the pin 4a2 does not the washer 424 touched, the latter is moved towards the stationary disk 426 by a helical spring 430 pressed, which surrounds a horizontally extending post on which one Nut 432 is screwed on, which can be adjusted inwards or outwards, to regulate the tension of the spring. The double-sole thread goes through from the supply an eye 434 through it, then between the disks 424 and 426 and then through an eye 436 and through an eye 44o carried by the arm q.2o and through another fixed eye 438 to the thread guide 336. The eye 44o moves between the two fixed eyes 436 and 438 to provide a thread take-up device, which acts to take up slack in the double-sole thread when the arm 42o moves in a direction opposite to the clockwise movement (in plan view shown) moves. From the arrangement described it can be seen that when the cutting and clamping devices as a result of swinging arm 352 in one of the Move clockwise in opposite direction outward, except pin 422 Engagement with the disk 424 comes, whereupon the tension of the spring 430 takes effect comes to cling this thread resiliently. The thread take-up acts at the same time 440 to pull this thread back through the thread guide, whereby this Thread is picked up and caused to lie within slot 414 comes. If the thread-picking movement is too great, the thread will be removed from the Supply withdrawn between disks 424 and 426, the spring 43o granted Tension is relatively easy.

After the individual parts of the machine have been described, its mode of operation in the manufacture of a stocking will now be explained. The needles, which have hitherto been generally designated 6, consist of three Groups (Fig. 20). The complete set of needles consists of needles 6a with short feet, Needles 6b with medium-long feet and needles 6 with long feet. The needles with short Feet extend over i8o °, while the needles with long and medium length Feet form the remainder of the circle; this circle is designed in such a way that that he has a group of needles with medium-long feet, which the middle Form part of the semicircle and these needles are the tip of the toe part of the Knit stockings. Sets of needles with long feet flank this middle one Row of needles with medium feet, with the needles with long feet covering the gusset form in the toe part. Then needles with medium-long feet are lined up again between the long needles and the ends of the row of needles with short feet lie. The needles with short feet knit the front part of the length and the upper part of the foot, while the needles with long and medium-length feet den back part of the length, the high heel, the heel, the sole and the toe part knit.

The stocking that can be made with the machine has a the upper part of the margin, which, as usual, is done on a marginal machine manufactured and transferred to the needles of the present machine. Next to this upper one Edge part is an elongated edge part, which is made up of a plurality of circular knitted courses. This is followed by the lengths in which finite the present machine patterns are made by plain thread; these patterns extend through the length, the ankle portion and the top of the foot and end behind the ankle part on the upper part of the heel. The patterns run preferentially through the high heel, although if so desired, at this point can end. The ankle part of the stocking becomes finite of the present machine circular knitted, and the high heel is different from the remaining parts of the ankle part through the insertion of the thread, the above with double-sole thread has been designated. The heel of the stocking is made by the usual diminishing and Several formed and, as explained above, on the needles with long and made of medium length feet. The foot of the stocking is knitted in the round made in a similar way to the ankle part; the bottom of the foot part is through Insertion of double soles reinforced. At the end of the knitting of the foot part the extended toe is made by circular knitting. The top which formed on the needles with long and medium-length feet is first through Lessen produced by needles being deactivated one after the other, whereupon all needles with long feet come into effect and a gusset on these needles is knitted, and as the weakening progresses, all the needles become long Feet set as a unit out of effect, whereupon the increase takes place. The stocking is then made by circular knitting of the loop stitches that go around completed. The needles and the tongue ring are then brought to the same height 32 is lifted, whereupon your -needle cylinder gives several turns "-earth to the To push off stitches from the needles. A thread guide remains at the end of this work 322 in the working position and naturally goes up with the tongue ring. The lengths as well the upper foot sheet of the stocking can, if so desired, from a plurality be formed by threads in a cladding layer.

When the machine is at a standstill, the needles are brought to the same height in order to take up the elastic edge. At this time, the thread guides 320 and 336 are inoperative, with the thread guide 322 in the knitting position and ready to knit the extended edge portion while the side triangles and cam portions 142, 144, 146, 148 and 152 are retracted from the knitting position are such that all these needles form a complete circle in a predetermined plane. At this time, the control surface 276 of the guard plate 272 comes into engagement with the working end of the pawl 256, whereby, despite any movement of this pawl 256, the pin wheel 250 is not given any rotation, since the low tooth 254 is opposite the pawl that was used during the completion of the previous stocking has been brought into this position. The control members 92 and 94 have been withdrawn by the action of the control members on the main control drum so that they do not engage the turn-over thread guides and thereby avoid movement of the turn-over thread guides during the initial formation of the extended edge portion. The upper sole thread remains within the slot 414, and the clamping and cutting device for this thread is withdrawn by the lever 352 in a direction opposite to the clockwise movement (as seen in plan view), while at the same time the double sole thread is withdrawn by the combined action of the tensioning forces. and the thread take-up device (Figs. 18 and 19) is prevented from opening a loop.

After placing the elastic edge on the at the same height If the needles are located, the tongue ring and the transfer thread guide head are lowered and operating the machine to produce the elongated edge portion, wherein the needle cylinder in a direction opposite to the clockwise movement (in seen from the top view). The extended edge part is knitted by a thread, which is fed through the thread guide 322 and which is initially across the needles is laid by hand. The side triangles are in effect in the usual way set by lying against the needles with short feet, so that needles with medium-length feet are the first to start knitting. The remaining Parts assume the positions already indicated. During the knitting of the extended Edge part, which in the usual way consists of a plurality of rounds, is the Pawl 256 due to the action of the tabs 264 of the pattern chain on the driven one Lever 262 go back and forth ineffectively. Because the control lever i 8o at that time are preferably ineffective, then the various pushers, their lower Ends protrude outwards, on the control part 164 in the folding position slide up. But there is no turning over because the turning thread guides are in their inner position are held by the ineffectiveness of the control parts 92, 94. Of the Control part 178, which is only effective when a pattern is taking place, is located also ineffective. As a result, the majority of the lower jacks with their lower ends remain in the inner layer; the spring band is generally not strong enough to move the pusher, which with considerable friction in the Fit slots.

Upon the formation of the extended edge part, a yarn change takes place by replacing the yarn guide 322 with the yarn guide 320 , which contains one or more yarns of the desired type for the purpose of forming the length. The control parts 92, 94, which control the action of the folding thread guides, are now optionally brought into action so that they can act on the feet of the folding thread guides. The feet are adjusted in a predetermined manner to produce the desired pattern in conjunction with the needle selection made. The arrangement in the present machine is such that a folding thread guide can be provided for each needle, so that, if so desired, all needles can be provided with folding threads and consequently very intricate patterns can be achieved.

During the formation of the elongation, the control levers 18o, which are on the feet of the lower jacks act as a result of the optional release by the Control parts 292, 29q. and 296 brought into effect. The mentioned control parts292, 294 and 296 are optionally available under the control of the associated control modules the control drum so that through several steps the pattern drum during formation the lengthening and of course also during the ankle part and the foot a control from the upper, middle and lower sets the control lever iSo is reached with the result that a longitudinal change in the folding thread pattern is achieved. For example, two sets of control levers can be used during the i8o Formation of the upper part of the length in effect to produce vertical stripes. If then make the usual knitted ornament on the side of the stocking which begins in the middle of the length and runs downwards, one can Set of control levers ineffective and the third set in effect, to regulate the outline for the knitted ornament. It should be noted that the working of these control levers is negative in one sense, d. H. a pusher whose If the lower end is pressed inwards by a control lever, a transfer thread becomes a thread omit, especially since it does not slide on the control part 166 to remove the thread from his include associated thread guide when this thread guide outwards and then is swung inwardly by the control members 92 or 94 and 1i2. The transaction of the pin wheel is here such that pattern despite this. negative work produced from which in turn it follows that very intricate patterns can be produced, when few control parts remain in progress.

After the pattern formation takes place on those needles which has been raised by the action of the control parts 2z8 and 164 on the lower pushers the lower and middle pushers are lowered by the control surface 1.62, while the needles are lowered through the upper guard control part to pass through the Knitting zone with needles that are not provided with folding threads to go through.

At the beginning of the formation of the length, the protective plate 272 is moved, so that its lower part is opposite the path of the reciprocating movement of the pawl 256 is located. The pawl is thereby made effective to incrementally move the pin wheel 25o according to the manner permitted by chain 266.

When the point for the beginning of the high heel is reached, get the drum r26 one step of movement to effect various new works; the needle cylinder continues to rotate in the same way as before. First of all, it can it is desirable that the patterning does not take place through the high heel, while on the other hand the thread is passed through the front part of the ankle from which length must continue to the top of the foot. In this case those are lower pusher 14, which belong to the sole needles (which of course the high heel form), provided with feet which come into engagement with the control part 182, the, now brought into effect and kept in effect during the formation of the high heel will. Accordingly, the various sole needles are controlled by the control parts 218 and 164 on the lower jacks are not raised, and consequently they are not up to take up the threads from the folding thread guides. The one with the sole needles unified thread guides continue to move across the needle circle like this by the control parts 92, 94 is determined. although, in the event the illustration is such that it is not adversely affected by this Removal of a control part, for example the control part 94, from the area of action can be avoided, so that then only the Umlegefadenführer, which with the Needles for the foot upper sheet are united, in their laying the thread paths through the control part are moved, which remains in effect. The lower feet will be jo in this case full of all thread guides that are united with the sole needles, omitted.

N. \ 'Enii the insertion of the threads through the high heel further is to take place, the control lever 182 is held inoperative until knitting of the sole part begins. Since the formation of the high heel takes place through circular knitting, so in this case the turning of the threads will take place as before.

The knitting locks keep their previous positions so that the The main thread or threads are knitted in the same way as before. In addition to these threads, the double-sole thread is now introduced, but only through the sole needles are knitted, cut off and clamped on after the feeding of the thread to the sole needles with each revolution of the needle cylinder is finished.

In order to ensure the effectiveness of the thread guide 336, which carries the double-sole thread and must be moved downwards in action in order to introduce this double-sole thread into the needle circle in front of the first sole needle, and which must be withdrawn, whereupon the last sole needle passes, is made possible that the thread 346 falls down by sliding the piston 350 from a control part of the main control disk, which up to this time has held the lever 346 and the thread guide 336 up. The thread guide 336 is now exposed to the action of the lever 3.1o, which is swung out with each revolution of the machine by the control part 344, which is carried by your sinker ring (FIG. 4). This control part is arranged so that, by its action, it lifts the thread guide 336, thereby preventing the supply of the yarn full of it to the needles for the foot top sheet, but which allows the thread guide 336 to fall down at the correct time so that the double-sole thread can be fed to the sole needles; the thread is trapped between the last needle for the upper foot and the first sole needle and removed after the thread is fed to the last sole needle before it has the opportunity to go to the advancing needle for the foot upper. Provision is preferably made to cut and clamp the double-sole thread during this work. The arm 352, which carries the cutting and clamping device for the double sole thread, is swung out in the clockwise direction simultaneously with the release of the tension on the double sole thread. The timing of the cutting and clamping device is such that immediately after the thread guide 338 has been activated and the first sole thread needle is provided with thread, the clamp releases the end of this double-sole thread so that it can move around the needle cylinder can. When the thread guide 336 has been brought up inoperative, the thread is drawn into the jaws of the cutting and clamping device, which is then actuated by the spring .fob, whereupon the driven part 374 is released by the control part 376 , so that the double-sole thread cut off and its end held by the jaws while it is guided by the upward movement of the thread guide 336 to a position above the needles to prevent it from being caught by any of the needles for the top of the foot. The clamping and cutting device 394 to 402 moves transversely to the needles into the position which is indicated at 159 in FIG. While two control parts 376, 378 are provided, these control parts act as a single one; the split is only because the timing of the machine is such that the cutter and clamp is swung inward at a time when the space between these control members is opposite the driven member 374 which of course does not move outward could if a single contiguous control part were provided. The idle movements of the cutting and clamping device resulting from this arrangement have no effect. The resilient position of the cutting and clamping device prevents damage to the machine in the event that an overhead needle accidentally engages the cutting and clamping device. The storage is here such that the cutting and clamping devices swing against the tension of the spring 388, should an obstacle of the type mentioned above occur.

During the formation of the high heel, the pin wheel 25o continues its step-by-step Movement in the usual " 'free way since the pattern at least is continued through the foot top sheet. The double-sole thread interferes with this the insertion into the threads through the high heel does not. After completion of the high heel, the feed finger for the double-sole thread becomes ineffective made to be raised by lever 346. At the same time, the clamping and cutting device for the double sole thread by swinging the shaft 362 withdrawn to the outside, whereby the tensioning device q.24 and the thread take-up device 440 can be made operative to clamp the thread and keep excited. Since the thread guide 336 is now completely raised, the thread between the retracted clamp and the finger gets into the slot 414 is withdrawn, even where it cannot engage the needles.

The heel of the stocking is made by reducing and multiplying in the usual way, while the sole needles do not knit here. Until the formation of the heel, the needles for the upper foot and the sole or the needles for the upper foot alone, depending on the conditions discussed above, have executed the pattern which is to be continued in the upper foot after the heel has ended and during of circular knitting of the foot. In order to ensure that the pattern is continued without interruption, the protective plate 272 is moved so that the overlying part 2.78 comes into lingual with the pawl 2.50 , which is now prevented from acting on the teeth of the ratchet wheel. As a result, the pawl 2,56 goes back and forth ineffectively while the pin wheel 25o remains in its position for the continuation of the pattern after the heel is finished. In order to prevent the movement of the thread guides, both control parts are disabled; This is necessary because the needles with short butts were brought up during the formation of the heel to an ineffective level in which they are usually able to take up pattern threads. The control members 18o are overridden by the members 292, 29q., 296, and the control member 178 is also withdrawn to avoid engagement with the pushers during the reciprocating movement.

At the last movement of the needle cylinder in the clockwise movement opposite direction and before the first clockwise reciprocation the needles with short feet are taken out of action while the needles with long and medium-length feet with the exception of the preceding needle in the row Remaining working position to go through the knitting point and the heel thread record, which simultaneously with the removal of the thread for the lengths in Effect is brought about, with the thread for the heel part in the present machine is the same thread that is used to form the elongated edge portion. To ensure that needles with short feet can be removed from the area of action, the combined lock part 1q. ¢, 146 receives an inward movement, so that the lock part 146 engages needles with long and medium-length feet. The Castle Part1152 gets a full movement inwards, while the lock part 1So turns to the same Time moved outwards. The driver or increase finger intended for lowering is located itself in its ineffective position between the effective and ineffective levels of the Feet. The position of the lock parts described requires the needles to be depressed with long and medium-length feet through the lock part 146, whereupon the upward movement follows the needles through the upper control part 161 of the control ring 16o. The needles with long and medium-long feet are therefore on a level below the lowest The end of the lock part 152 is lowered and is consequently over the lock parts 142 and 163 above and below the middle triangle and the side triangles 136, 14o go to form the stitches. The needles with short feet, on the other hand, slide via the control part 161 and are not detected and moved by the lock part 146 therefore at a higher level, so that they are captured by the lock part 152, whereby they are lifted up above all parts of the lock at the main supply point and then during the formation of the heel part in the inoperative upper level remain. However, the previous sole needle does not go through the knitting point during the first clockwise movement during the formation of the heel part, since it is detected by the ascending driver 158 and consequently in the ineffective Level is brought. With each reciprocation, the needles become the sole group engage with an ascending driver so that these needles are sequentially be put out of effect for the purpose of mitigation. The return movement follows immediately in the direction opposite to the clockwise movement, with the lock part 152 needles with short -; zen feet raises, whereupon the lock part 152 and the like the side triangles 144 and 146 in the ineffective position as well as the lock parts 15o and 148 are withdrawn. All sole needles guide the knitting process further out with the exception of those which are brought in by the said driver have been.

Upon completion of the decrease, the lowering driver 154 takes effect brought to lower two needles at the same time while introducing Drivers remain effective to raise the needles one by one. In this way the multiplying takes place for the heel, with the other parts in their previous ones Positions remain.

The unrotation of the needle cylinder becomes nlunilelir for knitting of the hu13teil resumed. All needles including the needles for that The upper sheet of the foot and any sole needles that are in the raised position will be lowered by the inward movement of the lock part 15o in the working position. the other parts then assume the positions which they assumed during the formation of the Had taken high heels. d. lt. The plate 272 is moved to the lower To bring part 274 opposite the pawl 136, which in turn is effective to to advance the pin wheel; the control part 92 is again effective to feed the thread guide, which are associated with the needles for the foot upper leaf to move during the Thread guide for the double-sole thread and the clamping and cutting device in turn become effective so that the double-sole thread is knitted through the sole needles will; the main thread is changed to the previous thread or threads To bring threads for the L iillgeil into effect. The control parts 17 8, 18o are then made effective again.

The completion of the sole is followed by the knitting of the extended toe part, the thread for the extended edge part in turn being replaced by the thread for the length by lowering the thread guide 322 and by simultaneously moving the thread guide 32o upwards. The double solele thread is withdrawn into slot d-14 as before. At this time, both control members 92, 94 are withdrawn from their action to stop the turning of the threads. The guard plate 272 is moved to bring the interface 276 against the path of reciprocation of the pawl 256. As a result, the pin wheel 25o will continue to move gradually under the influence of the pawl until the low switching tooth 254 comes to rest opposite the pawl, whereupon the movements of the pin wheel come to a standstill and the pawl continues to go back and forth ineffectively. This position is easily reached during the knitting of the extended toe, but will be reached a little before the completion of the stocking, so that the pin wheel is brought into the correct starting position for the purpose of forming full of patterns in your next zli knitting stocking.

The control parts 178, 18o, 182 are now taken out of action, so that the lower pushrods do not climb up over the control members 218 and 164, it unless it happens by accident.

On the termination of the relocated toe part through manufacture a plurality of rows of stitches that go around empty in circular knitting are followed by diminishing for the toe part, the parts taking the same position as they were during the Had taken less of the heel part. After the lessening continued so far is that all needles with long feet as well as the end groups of the medium-length needles have been withdrawn from the work area, while the middle group of the Needles with medium-length feet will continue to knit the tip of the toe piece alone, thinks a movement of the control disk takes place in order to initiate the formation of the gusset. The parts shown in FIGS. 17 and 2o are in a position that they take while the needles are in action. To the right one To achieve adjustment of these needles, the lock part 15o inwards and then during the same movement the main control troninlel moves outwards. The weight rtslewegung takes place by such an amount that the control part only with the needles long feet, and also takes place at the time the middle group of needles with medium-length feet passes this point. The location of the parts in FIGS. 17 and 20, the return movement corresponds to that of the clockwise movement opposite direction immediately following the work mentioned. The middle Group of needles with medium-length feet together with the following group of needles with long feet go through the rope locks, and the driver 156 just got the last of the previous needles with long feet into the ineffective Position introduced. Before the previous group of needles with long feet the position of the lock part reaches 1:11, the latter is uni such an amount moved inwardly to engage these preceding long-footed needles comes and lowers her so that her feet go through the opening 1q.5 pass between the lock parts 144, 146. The lock part 144 will not catch needles with short and medium-length feet. At the next one Backward movement in the direction opposite to that of the clockwise movement will therefore be possible all needles with long feet together with the middle group of needles with medium length Feet remain in the effective position, while the needles with short feet and the end group of needles with medium-length feet continue to find themselves in the ineffective Move level further.

The lock parts 14q., 146 - are then again in their previous ones Positions moved out as soon as the needles are lowered, and the same applies to the lock part 15o.

Since the knitting back and forth now takes place, the gusset is knitted, while the lessening is continued, the needles successively inoperative bring to.

After completing the required rows of stitches for the gusset part the control members 148, 152 are moved inwardly by a sufficient amount to be able to with to engage the feet of all needles with long feet that remain in effect. As a result, all the needles are brought up into the ineffective level, whereupon the continued movement of the main control drum controls the control members 148, 152 be rendered ineffective. The parts will be in those positions that they ingested at the beginning of the heel augmentation. The lowering one Driver is now brought into action to lower every two needles while the uplifting drivers continue to uplift the needles one at a time, so that the toe part increases.

'Zach finishing the multiplication will put the parts in a position to Brought circular knitting; the rotation of the needle cylinder is resumed, while the cam member 150 moves inward to bring all of the needles into the knitting position bring to. Then the loop stitches going around are knitted by the same Main thread is used, which was previously used to form the extended edge part, the Heel and toe part was used. After completing the loop stitches going around the needles are removed by pulling the different parts of the lock back onto the same Brought height, with the tongue ring is brought up and through the continued Twist the stitches to be dropped from the needles. By arranging the described Feeding devices for the main thread and the double-sole thread becomes any disturbance between these feeding devices and the pattern devices avoided which in particular then, "run every needle is provided with a thread, one Form a cage of folding threads that extends up and inward from the needles. By using a slot that is used to accommodate the double-sole thread in the inner surface of the tongue ring, picking up the sole thread becomes one undesirable time avoided.

In the above description of the operation, the more intricate ones have become Explains operations that occur when threading the needles to manufacture of patterns are fed. In the simpler cases, in the case of no pattern threads are used, the thread guide head is brought up, while the tongue ring remains in its lower position, and the operation is then similar to that described with the exception of the operations determined by the folding threads. Even during part of the knitting process, such as during an attempt, and in the event that folding threads are not inserted, this is the correct angular position between the thread guides and the needles through the uninterrupted drive by means of the shafts 56, 58.

A feature of particular importance is the use of nested Shafts to simplify the connections between the control drum and the finally to provide parts to be influenced. The waves 118, 12o form the a set of the nested waves, while those waves that make up the Shaft 362 have a different set, creating a multiplicity of levers and handlebar connections are avoided.

The most varied changes are in the details of the construction possible without deviating from your feature of the invention.
