Definitions

  • the invention relates to a method for producing surface-patterned plush goods, according to the preamble of claim 1, and to a circular knitting machine particularly suitable for carrying out the method according to the preamble of claim 4 or claim 5.
  • a color pattern can only be achieved by the detour that rows of individual colors are knitted in succession according to the number of colors of the pattern, each board forming only one plush handle within a color sequence.
  • only plush handles of the color that should be visible are formed in the goods, while the differently colored plush thread or the differently colored plush threads are processed in these surface areas in the basic goods without the formation of handles.
  • the result in the surface areas to be executed in a specific color is that the color is determined exclusively by the above plush thread forming the plush handles.
  • the handle density ie the ratio of the number of handles developed to knitted stitches, is constantly decreasing with a higher color number, or conversely the number of colors which can be processed is limited for a given handle density; because when processing about three colors, the handles of the color-determining plush thread can only be formed in every third row and must also cover the other two rows, in which the two plush threads that cannot be visually emphasized are incorporated into the basic fabric. Since this is of course only possible to a limited extent, the plush appears to be "sparse", and such an approach is therefore restricted in use.
  • pattern-based needle sorting it is possible to feed the plush thread only to those needles that are actually supposed to form plush handles. Where no plush loops are to be formed, the plush thread is not necessarily worked out into stitches. In principle, a material control on plush thread can thus be achieved with a needle control.
  • the last stitch formed can be unwanted, so that the last stitch slides over the closed tongue of one of the needles partially drawn off in the first system. Then the stitch wears the basic thread running in the hook opening and abruptly interrupts its supply to form the stitch, so that the basic thread inevitably breaks.
  • the movements of the needles selected for the detection of the plush thread and the unsorted boards are identical to the movements in the production of smooth or patterned plush goods.
  • needles not selected for grasping the plush thread remain in the concentric position, while all needles are expelled to produce smooth plush goods.
  • a float should in no case extend over more than about four to five stitches, which corresponds to a float width of 5 to 6 mm with a usual machine pitch of 18 or 20 needles per English inch.
  • the maximum width of a sample area in such a known method is thus limited to well below 1 cm, and larger sample areas cannot be produced.
  • an area-based pattern is generally possible, provided that shear plush is to be produced.
  • Such a proposal according to DE-C-671 333 consists in withdrawing that part of the needles not intended to receive the first plush thread fed in front of the basic thread under its thread guide, whereupon these needles are raised into the area of the thread guide feeding the second plush thread while the other part of the needles detects the plush thread that is fed in first and is then passed beneath the thread guide that feeds the plush thread.
  • the main disadvantage of this proposal is that, unlike in the method of US-A-2 715 824, the needles cannot be withdrawn to such an extent that the two groups of needles are at a sufficient distance from one another, in particular for the first plush thread without difficulty to be able to supply the provided needle group.
  • the needles not provided for receiving the first plush thread may only be withdrawn as far as is ensured that the needle heads are not closed. If needle tongues closed the needle head, there would be no possibility of opening these needle heads to receive the following basic thread or the second plush thread.
  • the first plush thread lies in a wave form between the needles, each driven out in a 1: 1 sorting, and is therefore exposed to very considerable tensions with regard to the movement required for the feed to the stitch formation point, which cannot be mastered in practice.
  • DE-C-671 333 in contrast to the also 1: 1 offset work of partial rows according to US-A-2 715 824, there is a double handle density, and thus also avoidance of the gas, but with a higher plush density.
  • the proposal of DE-C-671 333 theory has remained, since in particular the difficulties described as well as other difficulties could not be mastered in practice.
  • a method has become known from DE-A-2322 384, in which basic goods are formed both on cylindrical needles and on needles.
  • the knitted fabric formed by the needles lies on the side of the plush handles which are formed by the cylindrical needles.
  • this knitted fabric formed on the rib needles is not shown, so that it does not appear that the plush handles are actually covered by the knitted fabric formed on the rib needles, that is to say not at all can come. Since the plush handles must inevitably be in the opposite direction to the knock-off direction of the cylinder needles, and are thus aligned in the direction of the dial, any knitted fabric formed on the dial inevitably covers the plush handles.
  • DE-A-2 343 886 discloses a method with which plush goods with a similar pattern are also to be produced. Then all latch needles should first be driven out in the catching position. Tongue needles, sorted according to the pattern, are driven out of the catch position in the knitting position and capture a plush thread there. After a plurality of selection processes, in which different plush threads are picked up by correspondingly selected latch needles, the basic thread is fed in and knit off all the needles.
  • This process may be suitable for the production of the pile fiber fabric which is also to be produced according to DE-A-2 343 886, since here short pile fibers are inserted into the selected needles driven out in the knitting position, in which loop formation in the course of the knock-off movement of the cylinder needles is no longer necessary.
  • plush threads are to be supplied at the individual workplaces, there are insurmountable problems.
  • the sorting of the needles for picking up the plush threads at the various workplaces is intended to ensure that the needles selected for each plush thread only get this one plush thread put into the hook, while all the other supplied plush threads get on the back of these needles, so this sets ahead that the expelled needles let a plush thread that has already been fed slide off to the back of it. Even when using latch needles with plating heads, this is obviously not possible with the required certainty. Furthermore, the plush threads are then alternately in needle hooks and over the back of the needle over a plurality of workstations, but at the same time have to perform the feed movement required for stitch formation, which in no way leads to portable thread tensions. If, as Fig.
  • the plush thread is first fed to the back of the cylinder needles, where it is grasped by pulling hooks of a sinker ring reaching out between the driven out needles and pulled out to grinders between the driven out needles.
  • the plush thread is floated over a plurality of pulling hooks.
  • additional latch needles are driven into the areas of the floating plush thread and the main thread is fed to the latch needles thus driven out.
  • the plush handles can not be integrated as a stitch in this method, they are easily detachable from the basic fabric. Therefore, a product manufactured in this way requires a subsequent finish to fix the plush handles in the basic product. Furthermore, there is a problem that the length of the plush sleeves must not be less than a dimension corresponding to the needle tongue when the floating base thread is integrated as a stitch, since there must be space on the inside of the float for the closing movement of the needle tongue. This results in a high consumption of plush threads, whereby a subsequent shearing process would be necessary in the event that a low plush height is desired. For short-pile goods, this results in an extremely high consumption of plush threads, as should be avoided by using needle sorting compared to board sorting.
  • GB-C-462 662 refers to the possibility of providing catch meshes or floats in the non-plush areas of rows of stitches. With this proposal, a color pattern is made possible that is largely free of pattern restrictions, whereby pattern restrictions, similar to the circuit board control, result only from the pattern repeat of the pattern wheels for the circuit boards.
  • the needles either (1) remain in concentricity, or (2) are raised in the catching position, or (3) are driven out in the knitting position, the latter two needle groups but after deduction of the needles in the knitting position in the thread-laying position parallel above the feeder for the plush thread, so that both the basic thread and the plush thread are fed to these needles.
  • plush thread and base thread are either floated or plush thread and base thread are processed into fangs or stitches, but processing of the base thread in different ways compared to the plush thread is fundamentally excluded.
  • the plush handle must connect two adjacent stitches, there must be a stitch on both sides of each plush handle.
  • the invention is based on a method in accordance with US Pat. No. 2,710,527.
  • the advantages of this known method for achieving a plush fabric patterned in terms of surface area by needle sorting alone should also be retained within the scope of the invention.
  • the modification according to the invention of the generic method according to US-A-2 710 527 initially provides, according to the characterizing part of claim 1, that latch needles not selected for the detection of the plush thread - insofar as they do not remain in the concentric position anyway - before picking up the basic thread (either via the Knitting position in the thread laying position or in the catching position) are driven out, so that they can grasp the basic thread during the subsequent take-off movement. If this measure were used in the case of US-A-2 710 527, all the expelled needles, that is to say also the expelled needles not selected for plush formation, would catch both threads during the final tapping movement.
  • these latch needles have previously passed through the knitting position, the evasive movement to avoid the plush thread running into the needle head can easily lead to the extent that the stitch behind the tongue closes the tongue and thus provides a certain security against penetration of the plush thread. If the needles were previously in the catching position, the last stitch formed is still on the open tongue and therefore cannot close it even when the trigger is moved. It is therefore of particular importance in the context of the invention that these latch needles are withdrawn at the latest after feeding the base thread into a position in which the needle head is no more than about a hook height above the level of the plush formation edges of the (unsorted advanced) plush formation elements. In this way, the plush formation edges cover the hook opening alone or together with the closed tongue under all circumstances, so that unintentional grasping of the plush thread with these needles is certain to be ruled out.
  • the latch needles not provided for the detection of the plush thread are driven out before the base thread is picked up and these latch needles in their position driven out of the concentric position with their needle heads below the To pass the plush thread as it is being fed in and to withdraw it after the feed of the base thread into a position in which the needle head is at most by hook height above the level of the plush formation edges of the plush forming elements.
  • the base thread can be attached to the base fabric either in the form of tuck handles or loops.
  • all needles not selected for plush formation can be driven out of the concentric position and form stitches, so that a smooth basic fabric results, but single thread only from the basic thread without incorporating the plush thread that floats.
  • only every second, third or even fourth needle can form stitches, so that within a longer plush thread float, the base thread is floated over a small number of stitches and is only integrated into the base fabric by stitches at appropriate intervals (claim 2) .
  • a circular knitting machine with a needle cylinder and sinker ring for carrying out the method according to the invention is characterized by the characterizing features of claim 4 and claim 5, respectively.
  • the pattern slide only needs to transmit compressive forces to the needle shaft, and all retraction movements take place via lock parts acting on the control base of the needle shaft.
  • the retraction movement can be transmitted by the articulated connection from the pattern slide to the needle shaft.
  • the selection of the needles required for the method according to the invention according to their height can be achieved by the pattern device in such a way that the higher-standing needles the plush thread can be fed alone, while the lower needles are at most about hook height above the level of the plush formation edges and are thus secured against thread detection.
  • the sequence of movements of the plush sinkers is based on the generally known principle for producing smooth plush goods on machines with a needle cylinder and sinker ring.
  • the elements S of a pattern device are provided under the needles N in a manner known per se.
  • the stitch formation process begins in a known manner with the lifting of all needles by part H1 in the knitting position and the retraction by part R1 in the thread-laying position. The last stitches formed open the tongues, slide over them onto the needle shafts and are then pushed behind the needle tongues by pulling back the needles. Part R1 pulls the needles back so far that the needles are as low as possible, but the needles are not closed by the stitches behind them.
  • the unselected needles N2 are now pulled back by part R3 so far that their needle hooks are closed by the needle tongues and are at most at the height of the hook above the sinker lugs.
  • the available possible height difference determined by the tongue length of the needles, must be used to ensure that the needles N1 and N2 are guided separately. This means that the selected needles are lifted as high as possible, and the possibility that the supplied base thread can get onto the needle shaft must be prevented. Therefore, with such a selection principle, a part R2 is provided which pulls the selected needles N1 back a little shortly after part R3 has withdrawn the unselected needles.
  • Fig. 4 shows the feeding of the plush thread T. This is fed to the open needle heads of the selected needles N1. Since the hooks of the needles N2 are already closed, additional security is provided that the plush thread T is not caught by the needles N2 not selected.
  • the basic thread G is held in the throats of the sinkers in the needle heads of the needles N2 and on the tongues of the needles N1.
  • the needles N1 pull the needles N1 back to the needles N2 and all of them together in the knock-off position.
  • the needles N1 form common stitches from the base and plush threads, which are connected by the plush handles lying over the sinker lugs.
  • the needles N2 have formed single-thread stitches from the basic thread G. In areas of the needles N2, the plush thread T is nosed as thread floating over the sinkers.
  • FIG. 6 A further exemplary embodiment is shown in FIG. 6. All the needles are at least raised in the knitting position, the selected needles N1 by a part HS of the pattern device (see FIG. 13). A sufficient height difference is thereby achieved in order to safely control the needle groups N1 and N2 separately.
  • Part R1 pulls all unselected needles into the deepest thread-laying position
  • part R4 pulls all selected needles into the highest thread-laying position, as shown in FIG. 3.
  • the sinkers were withdrawn so that the basic thread can be fed in at D in FIG. 6.
  • the boards are then pushed with their noses between the needle shafts and at the same time the needles N2 are pulled through part R3 to such an extent that they are at most at hook height above the board noses. After the plush thread has been fed, all the needles are withdrawn by the needle sinker.
  • FIG. 5 A particularly favorable solution with regard to safe needle guidance and low thread stress is shown in FIG. 5.
  • a pattern device known per se is used, in which the control elements S of the selection device are pivotably suspended in the needles N, so that the needles can be lifted and retracted via the pattern device.
  • all needles are first lifted into the knitting position by the parts H1 and R1 and then withdrawn into the thread-laying position.
  • the sinkers were withdrawn so that the basic thread can be fed to all needles at the same height, as is done in the production of smooth plush goods.
  • the plush boards with their noses are pushed between the needle shafts.
  • the selection device selects those needles N2 which are not intended to capture a plush thread.
  • the needles N2 are therefore withdrawn into the position shown in FIG. 4 after the basic thread has been fed through the pattern device, while the needles N1 remain in the thread-laying position.
  • the plush thread T is fed, whereupon all needles are pulled back into the knock-off position by the needle counterbore.
  • Simpler patterns can also be worked according to the method described in FIG. 5 by using needle groups of different lengths that can be controlled separately.
  • a number of new pattern effects can be achieved with the exemplary embodiments described. Any effects can be achieved through different plush loops, depending on whether the plush loops connect two adjacent stitches or skip one or more stitches. In contrast to US-A-2 715 824, those areas in which the plush thread is not deposited can run over any number of stitches. This also applies to color patterns according to FIG. 22.
  • FIG. 22 a two-tone jacquard fabric is shown, in which a first plush material P1 and P3 with the basic threads G1 and G3 is knitted in the wales M4, M5 and M6, while in the wales M1 , M2 and M3 form the basic threads G1 and G3 alone stitches.
  • a second plush material P2 and P4 is knitted in the wales M1, M2 and M3 in the rows of the basic threads G2 and G3 lying between them.
  • the intermittent thread floatings that jump over the basic fabric lie on top of the plush side. They have to be removed to bring out the color swatch.
  • This is advantageously done by at least one shearing process after knitting. Such shear processes are provided several times for plush (velor), so that no additional effort is required in such cases. If care is taken during the patterning that the plush threads always deposit at least a certain number of stitches, it is also possible to cut open only the floats by making appropriate settings on the clipper.
  • the at least necessary number of stitches to be deposited by a plush thread depends on the machine division and the materials used and is to be determined by tests.
  • the plush handles are formed by latch needles, corresponding unproductive workplaces are to be provided in which only these needles are at full height have to be raised and pulled back without a thread to release the plush handles.
  • tongue openers are to be provided in order to open the needle heads to receive the plush material.
  • the needle control of the tongue needles forming the basic product can be carried out according to one of the exemplary embodiments described, the basic thread being fed behind the needle shafts of the needles forming the plush loops. Since it is always technically easier to select a needle in the cylinder, the basic product should be formed with the cylinder needles.
  • the latch needles in the dial are therefore replaced by so-called plush needles or plush boards L (cf. US-A-1 221 756).
  • the cylinder needles were controlled according to one of the previously described exemplary embodiments into an upper (N1) and a lower (N2) thread laying position or are at a height in a method according to FIG. 5.

  • the needles not provided for receiving a plush thread are withdrawn to such an extent that the needle head does not protrude beyond the plush elements if possible. 8
  • the plush thread T is then fed to the selected needles N1 and all the needles are brought into the knock-off position. When using plush needles or plush boards L, this remains driven out until the stitches are formed. Only then are they pulled back, thus releasing the plush bows.

  • the needles were sorted into different thread laying positions, or a sorting takes place after feeding the basic thread G (FIG. 5). Before the plush thread T according to FIG. 10 was fed in, all the needles N2 were pulled out of the area of the plush hooks. After the plush thread T has been fed in, the plush hooks are first pulled back and shortly thereafter the needles are pulled back by the needle sinker.

  • the plush thread is fed in and all the needles are withdrawn by the needle sinker SN. While in the plush areas all needles form basic and plush threads, the basic thread is only knitted by every second needle in the areas covered by the plush thread.
  • the floats of the base thread would lie behind three needles or stitches if a needle without a pattern foot were inserted between the needles with pattern feet F2 or F3.

Either those control slides of the needles previously raised only via one of the pattern feet or all of the needles not previously selected are brought into the area of a retraction part. After the feed of the base thread, this pulls the needles or control slides, which were previously only raised via one of the pattern feet, into a position in which the needle hooks protrude at most at hook height above the sinker lugs controlled between the needle shafts. The plush thread is fed to the needles remaining in the thread-laying position, whereupon all the needles are pulled back into the take-off position by a needle countersink SN.
  • the control in all three knitting positions for needle selection can be carried out using other control options (e.g. sample wheels). This also applies to the withdrawal of the needles, which also e.g. can be done by appropriately mounted sample wheels.
  • a colored patterned plush fabric is shown in Fig. 24.
  • the first plush threads P11, P12 and P13 are knitted with basic threads G11, G12 and G13 in the wales M1, M2, M3 and M4.
  • the basic threads G21 and G22 are integrated in every second wale as catch stitches, which are connected by thread floats.
  • the basic threads G21 and G22 form common stitches with the second plush threads P21 and P22, the basic threads G11, G12 and G13 being in every second wale (M6 and M8) as Catch mesh can be integrated. It is at the discretion of a specialist to move the integration of the basic threads to be tied alone in rows (M1 to M4) or to leave them unattached (M5 to M8).
  • inserting the plush thread over the sinker lugs after feeding the base thread below the sinker lugs achieves the highest level of safety in thread guidance, but sorting into two thread laying positions requires certain requirements (needles with a long tongue).
  • the selection and guidance of needles in two thread-laying positions can be avoided by inserting the plush thread in the knitting position before feeding the basic thread.
  • FIG. 17 An exemplary embodiment of this is shown in FIG. 17.
  • all needles are over Part H1 in knitting position, selected needles also raised. While the non-selected needles N2 are retracted as far as possible into the thread-laying position by part R1, the selected needles N1 are only retracted by part R4 after a plush thread T has been fed to them at position F in FIG this is shown in Fig. 18.
  • the basic thread G according to FIG. 19 is fed under the retracted sinker tabs and these are then controlled between the needle shafts. Due to the correspondingly high plush thread, this is still above the sinker lugs.
  • the unselected needles are then withdrawn to such an extent that the needle heads are at most at hook height above the sinker lugs. This means that the plush thread only comes into contact with the unselected needles shortly before all the needles are withdrawn by the SN needle counterbore.
  • known needles with a pre-bent plating head are used. This also makes it possible to dispense with separate guidance of the needles in the thread-laying position.
  • a needle control as described in connection with FIG. 13 has to be used. 14 to 16 can also be used for this purpose. Depending on the desired pile density, all needles are in the knitting position, or a part is lifted over one of the needle feet in the catching or knitting position. If the needles were raised in the knitting position, they are then withdrawn by part R1 in the thread-laying position. The pattern device then lifts selected needles to the knitting position or, if a secure thread feed is required, beyond. The plush thread T is fed in as shown in FIG.
  • the combination of the variously described feeding options for the plush thread makes it possible to bind two plush threads with one basic thread with a constantly changing needle sorting and with sufficient spacing of the individual needle groups from one another when feeding the plush threads.
  • FIG. 20 A corresponding exemplary embodiment is shown in FIG. 20.
  • a pattern device is used, by means of which the needles according to FIG. 5 can both be raised and lowered.
  • the selection device also raises needles.
  • Part R1 withdraws the unselected needles in the thread-laying position.
  • the selected needles are also withdrawn by part R4 in the thread-laying position, and the basic thread is fed (FIG. 20, position G).
  • the sinker noses are controlled between the needle shafts, the selected needles N1 are pulled back again by the pattern device to such an extent that they protrude above the sinker noses at most at hook height.
  • Another option for needle control is to raise all needles in the knitting position and to withdraw selected needles in the thread laying position. While a first plush thread is fed to the unselected needles and they are then retracted into their thread-laying position via their working foot F1, the first needle sorting is deleted and those needles are selected which were not previously selected. These needles, which have previously grasped the first plush thread, are now withdrawn so far, while the sinker lugs are being steered between the needle shafts, that their heads are at most at hook height above the sinker lugs. After the second plush thread T1 has been fed to the remaining needles, all needles are pulled back into the knock-off position by the needle counterbore.
  • all needles can first be raised to the knitting position and then retracted to the thread laying position according to FIG. 1. Then the pattern device lifts selected needles for receiving the first plush thread again and pulls them back after they have been withdrawn in the thread-laying position, a basic thread has been fed and the sinker noses are controlled between the needle shafts, so far that the needle heads are at most at hook height above the Circuit board lugs stand. After the second plush thread T1 has been fed to the needles remaining in the thread-laying position, all the needles are withdrawn by the needle sinker SN.
  • the goods shown in FIG. 25 can be manufactured according to one of the exemplary embodiments described above.
  • the needle control according to the invention can, however Needle sorting and therefore the number of stitches formed by the two plush threads can be changed in rows.
  • FIG. 26 An exemplary embodiment is shown in FIG. 26.
  • sample slides to be pivoted are hung by a pattern selection device known per se.
  • these pattern slides are pivoted into the working position (SM) or in the rest position (SH).
  • SM working position
  • SH rest position
  • those pattern slides are brought into working position SM, the needles of which are intended to grip one of the plush threads.
  • These needles N1 are lifted by the part HS1 into the knitting position via the pattern slide and retracted via the working foot F1 through part R1 into the thread-laying position.
  • those needles N2 with sample foot F2 are raised by part H2 in the catch position to open the tongues and withdrawn by part R7 in the concentric position.
  • a further selection of the pattern slides is carried out while the selected needles are withdrawn in the thread-laying position. Only those pattern slides remain in the SM working position, the needles N11 of which are intended to catch the first plush thread. For this purpose, they are brought back into the knitting position by part HS2, while the remaining needles N12 previously raised in the knitting position remain in the thread-laying position.
  • a first plush thread is fed to the needles N11 and part R2 pulls them back into the thread-laying position.
  • the needles N2 provided for catching the catch are lifted from the unselected needles to such an extent that their heads later protrude at most from the hooks at hook height.
  • the basic thread is now fed under the sinker lugs and the sinker lugs are controlled between the needle shafts.
  • the pattern slides in the working position are now pulled back with their needles N11 by part RS1 to such an extent that they protrude at most from the hooks at hook height.
  • the second plush thread is now fed to the needles N12 remaining in the thread-laying position, and then the needle sinker SN withdraws all the needles in the knock-off position.
  • the needles N2 provided for catching can also remain in the catching position after being raised in the catching position. This eliminates part R7, the needles N2 remain at a level with the needles N12 running in the thread-laying position. Since the needles N2 are not allowed to catch the second plush thread, it is necessary, after the HS2 part, to put either the pattern pusher needles N2 or all the pattern pusher that was inactive in the first selection into the working position, so that the needles N2 pass through their pattern pusher through part RS1 are pulled out of the area of the second plush thread guide. The same procedure must be followed if all or part of the needles are to form stitches with the basic thread alone in the areas deposited by the plush threads.
  • the pattern pusher needles N2 or all the pattern pusher that was inactive in the first selection into the working position so that the needles N2 pass through their pattern pusher through part RS1 are pulled out of the area of the second plush thread guide.
  • the same procedure must be followed if all
  • Needles with pattern foot F2 are raised by a corresponding part H2 or all needles above their working foot in the knitting position and withdrawn by part R1 in the thread laying position.
  • Selected needles N11 are now raised again via part HS2 via their pattern pusher. While they are pulled back through part R2 with the first plush thread fed in, the pattern slides are re-sorted.
  • those pattern shifters are now brought into the working position, the needles of which are also not intended to grip the second plush thread, so that these needles are pulled back by part RS1 before the supply of the second plush thread so that their needle heads are at most at hook height above the noses of the boards protrude.
  • the needle sinker SN retracts all the needles in the knock-off position.
  • a further possibility of the needle control consists in lifting the needles provided for receiving one of the plush threads or for knitting the base thread alone in the knitting position and then withdrawing all the needles not intended for receiving the first plush thread by another selection of needles in the thread laying position.
  • Non-selected needles of the first sort can be lifted by one of the pattern feet in the catch position.
  • a first plush thread is fed to the needles remaining in the knitting position, whereupon they pull back a retracting part in the thread-laying position.
  • the sinkers are withdrawn and the basic thread is fed, whereupon the sinkers are steered with their noses between the needle shafts.
  • a further sorting of the needles retracts all the needles which are intended to grip the second plush thread, so that they protrude above the sinker lugs at most at hook height. After the second plush thread has been fed, a needle counterbore pulls all the needles back into the knock-off position.
  • goods can also have rows of stitches of a known type, or threads of a known type can additionally be knitted.
