Definitions

  • a number of the listed options for manufacturing l ung patterned plush knitted fabrics has also been transferred to machines with needle cylinder and dial.
  • the task of the tabs to form plush handles is either one of the two rows of needles (e.g. DE-PS 706.809) or the plush boards used in place of a row of needles (e.g. DE-PS 1 221 756) or plush hooks (e.g. DE-PS 1 816 846, US Pat. No. 3,241,337, DE-OS 2 704 295, DE-OS 2 918 903).
  • Color patterns according to US Pat. No. 2,710,527 are distinguished by a high pole density. Since the basic threads of a pattern color bridge the pattern areas formed by the other ground yarns as floats, these Fadenflöttungen limit the width pure colored M u-ster lake: there - to the pattern to take full advantage - cut the floating pile threads and must be dissipated. Longer base thread floats can also be lifted and cut open, making the goods defective.
  • Patterned plush goods in which two plush threads were alternately knitted with a basic thread according to DE-PS 671.333, have the highest possible plush density, but the pattern is determined by the sequence of the two needle groups used, which must be guided independently in their own lock channels. Since the two needle groups capture their assigned plush thread at the same height, one needle group must be withdrawn after the first plush thread has been fed in, while the other is raised. Thus, the use of an ex because that only one F USS row sorted and thus only a movement with a needle group can handy selector from be performed. Another disadvantage is that the first plush thread must be fed between the needle heads of the two needle groups, which are only slightly separated from one another, and must pass with absolute certainty behind the lower needle heads of the one needle type.
  • the object of the invention is therefore to develop methods for patterning knitted plush goods, in which, by means of selection devices known per se, only the tongue needles intended for forming the basic goods can be sorted in rows at will, while the plush elements provided for the formation of handles - boards, plush hooks, needles - uniformly necessary for the formation of handles Perform movements.
  • the aim should also be that the basic thread is always guided safely below the sinker lugs and that no stress is caused by the needle tongues that it opens. It is also sought that the basic thread in the area of a plush thread exposed to any number of needles is grasped by all or part of these needles and is connected to the goods base alone or with another plush thread.
  • the needles which are controlled at different heights, are at a sufficient distance from one another so that the plush threads can be inserted safely and the needles that grip the second plush thread do not get into the area of the first plush thread.
  • the object is achieved either in that the basic thread is supplied in a manner known per se to all the needles withdrawn from the concentric position in the catch position or after full lifting in the thread laying position, whereupon those needles which only knit the basic thread are withdrawn so far that the needle tongues close the needle hooks and only the needle hooks stand over the sinker lugs that are simultaneously guided between the needles, so that the plush thread subsequently fed is only inserted into the predetermined needles, which are then pulled to the previously withdrawn needles and together with them in the knock-off position, or that the needles for receiving a plush thread are raised above the needles that only grasp the basic thread and a plush thread is fed to them alone, whereupon they are withdrawn to the needles already controlled in the thread insertion or catch position, a basic thread is fed in under the sinker tabs and the board ns between the needles are controlled, whereupon either all needles are withdrawn in the knock-off position or all needles with the previously inserted first plush thread and,
  • the advantages of these methods are that with any needle sorting there is a secure guidance of the base thread underneath the sinker lugs, the base thread is not claimed by opening the tongue, the base thread is entangled in the fabric base by any, always changing number of needles, while the Plush thread is deposited, whereby the pile density can be increased in the case of color samples by appropriate needle selection and control, the distance between the needle heads of the needles guided in different positions when a plush thread is fed ensures that the plush thread is inserted securely, so that when two plush threads are fed to a workstation, a needle selection is made by one A selection system known per se is sufficient, since the selected needle group is first raised above the catch or thread insertion position in order to grasp the first, plush thread fed in higher, and then this needle group is fed over the same sort after feeding the basic thread tion withdraws from the thread laying position, whereby the non-selected needles catch the second plush thread.
  • part of the needles can only process the basic thread, so that two workplaces with a total of four plush threads can form a complete course.
  • a Series of the already known goods structures with higher operational reliability and in addition many new goods, in particular patterned from different pole materials in high pole densities, can be produced without technical restrictions.
  • 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 the needles by part H 1 in the knitting position and the retraction by part R 1 in the thread laying position. The open The last stitches formed form the tongues, slide over them onto the needle shafts and are then pushed behind the needle tongues by withdrawing the needles. Part R 1 pulls the needles back so far that the needles are as low as possible, but the tongues are not closed by the stitches behind them.
  • the unselected needles N 2 are now withdrawn by part R 3 so far that their needle hooks are closed by the needle tongues and are at most at the level of the hook above the sinker lugs.
  • the available height difference determined by the tongue length of the needles, must be fully used to ensure that the needles N 1 and N 2 are guided separately. This means that the selected needles are lifted as high as possible, the possibility that the supplied basic thread can get onto the needle shaft must be prevented. Therefore, with such a selection principle, a part R 2 is provided which withdraws the selected needles N 1 somewhat shortly after part R 3 has withdrawn the unselected needles.
  • the needles N 1 and N 2 are at a large distance from one another, so that the plush thread can be fed between the needle heads with great certainty.
  • These needle positions are reached at C in FIG. 1.
  • the needles N 1 can also be selected after the feed of the base thread and after the plush sinkers with their noses have been steered between the needle shafts. 4 shows the feeding of the plush thread T. This is fed to the open needle heads of the selected needles N 1 . Since the hooks of the needles N 2 are already closed, there is an additional guarantee that the plush thread T will not be caught by the needles N 2 that are not selected.
  • the basic thread G is held in the throats of the sinkers in the needle heads of the needles N 2 and on the tongues of the needles N 1.
  • the needles N 1 are pulled back to the needles N 2 and all together in the knock-off position by the needle countersink SN.
  • the needles N 1 form common stitches from the base and plush threads, which are connected by the plush handles lying over the sinker lugs.
  • the needles N 2 have formed single-thread stitches from the basic thread G. In areas of the needles N 2, the plush faced thread lies as a float over the sinker noses.
  • FIG. 6 Another exemplary embodiment is shown in FIG. 6. All needles are at least raised in the knitting position, and the selected needles N 1 are also raised by the pattern device. A sufficient height difference is thereby achieved in order to safely control the needle groups N 1 and N 2 separately.
  • Part R 1 pulls all unselected needles into the deepest thread laying position
  • part R 4 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 N 2 are pulled off by part R 3 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 The ideal solution in terms of safe needle guidance and low thread stress is shown in Fig. 5.
  • This will be a known pattern direction used, in which the control elements S of the selection device are pivotally suspended in the needles N, so that the needles can be raised and retracted via the pattern device.
  • all needles are first lifted into the knitting position by the parts H 1 and R 1 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 N 2 which are not intended to capture a plush thread.
  • the needles N 2 are therefore retracted into the position shown in FIG. 4 after the basic thread has been fed through the pattern device, while the needles N 1 remain in the thread-laying position.
  • the plush thread T is fed in, whereupon all the needles are finally pulled back into the knock-off position by the needle sinker.
  • 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 described exemplary embodiments. 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 Pat. No. 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 samples according to FIG. 22.
  • a two-tone jacquard fabric is shown in FIG. 22, in which a first plush material P 1 and P 3 is knitted with the basic threads G 1 and G 3 in the wales M 4, M 5 and M 6, while in the wales M 1, M 2 and M 3 the basic threads G 1 and G 3 alone form stitches.
  • a second plush material G 2 and G 4 is knitted in the wale M 1, M 2 and M 3 in the intermediate rows of the basic threads G 2 and G 4.
  • 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 the mixes 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 raised to the full height and without Thread must be pulled back to release the plush handles.

  • the needle control of the latch needles forming the basic product can be carried out according to one of the described exemplary embodiments, with the supply of the basic thread 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 Pat. No. 1,221,756).
  • the cylinder needles were controlled according to one of the previously described exemplary embodiments into an upper (N 1) and a lower (N 2) thread laying position or are at a height in a method according to FIG. 5.

  • the needles were sorted into different thread laying positions, or this 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 N 2 were pulled out of the area of the plush hook. After the plush thread has been fed in, the plush hooks are first pulled back and shortly thereafter the needles are pulled back by the needle sinker.

  • they are brought back into knitting position by part HS 2, while the remaining needles N 12 previously raised in knitting position remain in the thread laying position.
  • a first plush thread is fed to the needles N 11 and part R 2 pulls them back into the thread-laying position.
  • the needles N 2 provided for catching the catch are raised so far from the needles not selected 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 must slide in the working position are now pulled back with their needles N 11 by part RSJ1 to such an extent that they protrude at most from the hooks of the sinker at hook height.
  • the needles 12 remaining in the thread-laying position are now supplied with the second plush thread and then the needle sinker SN retracts all the needles in the knock-off position.
  • the needles N 2 provided for catching the catch can also remain in the catch position after lifting. This eliminates part R 7, the needles N 2 remain at a height with the needles N 12 running in the thread-laying position. Since the needles N 2 are not allowed to grasp the second plush thread, it is necessary, after part HS 2, to bring either the pattern slides of these needles or all of the pattern slides controlled inactive in the first selection into the working position, so that these needles N 2 over their pattern slides are pulled out of the area of the second plush thread guide by part RS 1. 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.
  • needles with sample foot F 2 are raised by a corresponding part H 2 or all needles above their working foot in the knitting position and retracted by part R 1 in the thread-laying position.
  • Selected needles are now raised again via part HS 1 via their pattern pusher. While they're through Part R 2 are withdrawn with the first plush thread fed in, the pattern slides are re-sorted.
  • those pattern shifters are now brought whose needles are also not intended to capture the second plush thread, so that these needles are retracted by part RS 1 before the second plush thread is fed in so far that their needle heads do not exceed the hook height the tabs of the boards stick out.
  • 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 in, 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 have rows of stitches in a known manner, or threads can also be knitted in a known manner.
