Definitions

  • the invention relates to a method for producing an optionally patterned pile embroidery on a circular embroidery machine with tongue needles arranged in the needle cylinder, horizontally mounted sinkers and carding devices for combing the pile fibers, in which needles during the knitting of a pile fabric optionally combed with additional threads before the take-up of the base thread involve.
  • Circular knitting machines for the production of nonwoven fabrics are known from DE-PS 370 736. All needles are driven out at knitting height, i.e. that the last stitches formed behind the needle tongues reach the needle shaft and then the needles are guided at this height by the combing wheel of a carding machine which dissolves a sliver and is arranged on the machine per work system, whereby the fiber material gets into the needle heads. Then a basic thread is fed to the needles, the needles are withdrawn, knitting stitches from the combed fibers together with the basic thread.
  • needles remain in the knitting position until they have taken over a second pile material from a combing wheel of a second card. If more than two different pile materials are to be integrated in a row of stitches, the selected needles are withdrawn in the thread-laying position and the described needle control is repeated to take up further pile materials. As soon as the desired number of pile materials has been entered, after the last combing in, all needles that have already passed through this card area in the catch or thread insertion position are raised to the other needles in the knitting position, a basic thread is fed in and all the needles are withdrawn to form the stitch.
  • the air jets provided for aligning the pile material now cause the fiber pile to be blown sideways, so that it comes under the nose of the board when the previously withdrawn boards are pushed forward.
  • the sinker noses must hold onto the fiber web, because when the needles are subsequently driven out at knitting height, the fiber web must first open the needle tongues and then get behind the open tongues. Then a basic thread is fed and the needles are pulled back to form stitches.
  • a decisive disadvantage of the circular knitting machines known hitherto is the needle drive provided for combing in knitting height. This has a particularly negative effect on the last-described US Pat. No. 3,226,952. Combing the pile of fibers in the highest needle position is also necessary because the shape of the previously customary boards means that the bottom edge of the board lock cannot be arranged lower than the level of the knock-off edge of the boards. The height of the entire blank lock cap therefore requires a corresponding arrangement of the cards and thus a corresponding needle stroke. This needle stroke must therefore be largely maintained in the newer high-performance machines, although it could be reduced by shortening the hinge length of the needles. In this case, the needles must be raised beyond the stroke required for stitch formation.
  • the invention has for its object that the needles are driven out only as far as necessary to comb the pile fibers and to take up the base thread.
  • the object is achieved in that the needles receiving the pile fibers are passed through the combing wheel at least over part of this distance in a height position in which the open tongue ends extend below the tapping edge of the boards.
  • the carding wheels are, if appropriate, designed as bevel gears according to the angle of the needle path during combing or are mounted at an appropriate inclination.
  • the lock parts for the needle guide are shaped so that the highest needle output to release the last formed stitches can take place before, after or during the combing in of the pile fibers. This makes it possible to produce new types of goods using appropriate process steps.
  • the advantages to be achieved with the invention are that by shortening the needle stroke with the same combing width (card width) the system width is reduced and additional work systems can thus be arranged with the same cylinder circumference.
  • the lower arrangement of the sinker cap makes the entire stitch formation process visible and controllable from the front.
  • tongue holders can be dispensed with, which also avoids a source of contamination and errors.
  • the needles already provided with fiber pile can be guided much deeper than in the thread-laying position, so that the selected needles do not have to be raised beyond the catch position even in the following selection and combing operations. This facilitates the incorporation of fibrous web in the form of catch mesh.
  • the support in the outer sinker ring RA or ring part if the outer and inner ring form a unit - compared to the sinker support in the inner Ring or ring part RJ arranged lower.
  • This difference in height and that between the tapping edge A and the leading edge F of the angled board P should advantageously correspond to the height of the board cap consisting of board locks PS and lock carrier PT, so that the top edge of the board cap does not substantially project beyond the tapping edge A of the boards.
  • the length of the tapping edge A required by the movement of the sinker can have an adverse effect on heavy qualities, since the last rows of stitches formed lie horizontally on this level.
  • the fibrous web is thereby pressed upwards so that, with a corresponding amount of fibers, it reaches the area of the combing wheel, which is now arranged lower, and could be grasped by the latter. Since this must absolutely be avoided, it is suggested to work with split boards.
  • FIGS. 1a and 1b A two, side-by-side circuit board is shown in FIGS. 1a and 1b.
  • a fixed board PA guided by a foot C in the outer and by a corresponding shaping around the inner board ring, can fall off with its tapping edge A immediately after the needle back.
  • the movable circuit board part PB is guided exclusively in the outer circuit board ring and controlled via the foot V through the circuit board locks.
  • the board part PB has only the board nose and throat in the front area and resiliently lies against the fixed board part PA. When pushed forward, the board prevents the goods from moving with the rising needles (Fig. 1a), while withdrawn (Fig. 1b) allows the formation of stitches over the knock-over edge A.
  • the two board parts PA and PB are one above the other.
  • An overlap should only take place in the area of the knock-over edge and the nose of the sinker in order not to bring the goods between the sinker parts.
  • Such an arrangement would have the advantage over the side-by-side board parts that the board thickness in the guide area and therefore the control foot V would be larger.
  • a tongue holder can be dispensed with. Since the needles according to curve 1 are only raised to the catching position T, the stitches formed last open the tongues without releasing them. In this position, the combing wheel K combs the fiber web. After the card, the needles are driven out to the full knitting height L. With a corresponding arrangement of the basic thread guide - he feeds the basic thread before releasing the needle tongues at a height that prevents the basic thread from getting behind the tongue tip LS - a tongue holder is not necessary.
  • all needles are raised to the knitting height L and retracted into the thread laying position T during the combing-in process. After feeding the basic thread, all needles are pulled off into the knitting position.
  • the needles can be sorted by all known selection devices. Since the pile fibers are combed in the catching or thread insertion position, it is necessary to guide the needles not intended for receiving the pile fibers in a lower position - preferably in the concentric position.
  • the needles intended for receiving pile fibers were first raised to a knitting height L, a basic thread would have to be fed into the combing zone and all selected needles withdrawn. In order to avoid the resulting floatation of the base thread, one would have to enlarge the system width, so that after the selected needles have passed through the combing wheel, the other needles can at least be driven to the catch or knitting height before the base thread is fed. It is therefore more favorable to bring the needles N 1 provided for the pile pickup into the catch position T (FIG. 13) according to the needle curve 1 in FIG. 6 and then to let them run through the combing wheel in this position. Then these needles are raised to the knitting position L.
  • the needles are selected in such a way that, after the inclusion of the colors, fiber strength, fiber behavior, etc.
  • Different pile materials were formed by a corresponding number of card devices from each needle a stitch.
  • the nature and sequence of the as Basic threads to be integrated in catcher stitches are known to any person skilled in the art and, depending on the required requirements, can be determined by them.
  • the thread floatings between the individual catch meshes should not become too large so that longer thread floatations cannot be lifted up, which could cut them off in the subsequent equipment during shearing operations. This would lead to errors in the knitted fabric.
  • the needles N 2 (FIG. 13) that remained in the concentric position during fiber combing can, of course, in deviation from the needle path 2 of FIG. 6, also be raised together with the needles N 1 into the knitting position, while the remaining needles according to the needle path 3 in remain in the concentric position.
  • Fig. 7 shows that the needles of the needle track 2, as described above, after passing the needles of the needle track 1 through the combing wheel K and then all these needles are driven out in knitting position.
  • the needles of the needle path 3 are simultaneously driven out into the catching position T 1. After feeding the basic thread, all needles are withdrawn. If the pattern device permits, a further group of needles, which always remains in concentricity, can be provided.
  • FIG. 8 shows that the needles selected for receiving pile fibers are lifted according to the needle path 1 in the catching position T in order to rise in the knitting position by the combing wheel K during the pile combing. Due to the higher needle and combing wheel position at this point, it is now also possible to at least partially raise some of the needles according to the needle path 2 during the combing process into the catching position T 1.
  • the needles not provided for picking up the pile or for incorporating the floating base thread remain in the concentric position according to the needle path 3. This needle control only requires a slight increase in the system width.
  • the needles not intended for pile picking can at least partially controlled in knitting and / or catching position.
  • a further selection device for selecting the needles picking up the small pile must be present after or shortly before the combing ends.
  • the use of needles of different lengths and / or different foot heights is sufficient.
  • FIG. 19 shows a product manufactured according to FIG. 6 or FIG. 8. It consists of wales A 1, A 2 and A 3, in which the basic threads G 3, G 5 and G 6 form stitches together with a first pile material.
  • the basic threads G 1, G 2 and G 4 are alternately integrated as catch stitches and thread floats, while they are knitted in the wale stitches B 1, B 2 and B 3 with a second pile material to form common stitches and the other basic threads are alternately catch loops and Form thread floats. If stitches are formed instead of the tuck handles, the pile density is reduced, but the production output increases.
  • FIG. 9 An exemplary embodiment of the method according to the invention for producing such a product characterized by different pile materials is shown in FIG. 9.
  • the needles N 1 intended for receiving a first pile material are lifted over the pattern device according to the needle path 1 in the catching position, while all other needles N 2 remain in the concentric position (FIG. 13).
  • the needles are only pulled back so far that the needle head is slightly above the nose of the sinker (FIG. 14).
  • needles N 2 for receiving a second pile material in the catching position are now driven out of the concentric position according to the needle path (FIG. 15). In this position, they pass through the combing wheel K 2 of another card, in order to then be withdrawn to the needles already provided with pile. Now needles are sorted again from the concentric position into the catch position (needle path 3). A third pile material is fed through the combing wheel K 3. After passing through the combed zone, all needles with the combed pile material, possibly also a fourth group of needles, which does not incorporate a pile, are raised to the knitting position L, the basic thread is fed in and all needles are withdrawn, whereby the combed fibers form stitches with the basic thread .
  • FIG. 10 Such an embodiment is shown in FIG.
  • all the needles are raised according to the needle N 1 in FIG. 14, so that the needles not intended for picking up the pile are guided at a height.
  • the needles selected for the.Flor recording rise according to the needle path 1 to the catch height and pass through the first pile material in this position leading Kradenrad K 1. Then they are pulled back to the other needles.
  • Another selection apparatus selects those needles; which are lifted into the catching position for receiving a second pile material corresponding to the needle path 2 and pass through the combing wheel K 2.
  • the sinkers are only withdrawn during the feeding of the basic thread. Between the knitting points, they remain in their concentric position and thus support the combed fiber web, which must be kept separate from the goods, and which must be lifted up when the needles are driven out into the knitting position.
  • the needles are inserted into two needle groups, for example long and short shafts, which alternate individually and the needles of the first group N 1 are raised to the catch position (FIG. 13), while the needles N 2 of the second group are in the concentric position remain.
  • the combing wheel K 1 pile material then combs into the needles of the first group, whereupon the needles are withdrawn into the concentric position.
  • the boards are also guided outwards so that the needle heads pull the pile material onto the base material.
  • the sinkers are again controlled to M ash center and the needles N expelled 2 of the second group in the full knitting height L. Furthermore, a basic thread is fed and these needles are withdrawn again.
  • the needles N form 2 stitches which are connected by thread floats W. These thread floats W lie behind the needles N 1 on the combed pile material S. Thus, this material previously combed into the needles N 1 can no longer be lifted later with the needles.
  • the needles N 2 are raised to the catch height, it is combed in as it passes through the card K 2 pile material and the needles are then withdrawn into the concentric position. By retracting the sinkers during the needle retraction, the pile material is drawn to the goods unhindered. Now the needles N 1 are raised to the knitting position L, the thread floatings Wdas the pile material previously covered by these needles on the goods and prevents rising with the needles.
  • a basic thread is fed in and the needles N 1 are withdrawn so that they form stitches from the basic threads, which are connected by thread floatings behind the needles N 2, which the pile material previously combed into these needles when these needles are later driven out of the basic fabric hold.
  • the pile material S rests on the needle machines as a catch stitch and is bound by the sinker loops on both sides of the thread floats W.
  • One possible pattern would be to sort each of the two needle groups in front of at least two successive cards. Thus, all of the needles in one group of needles would have picked up pile material before the needles in the other group knit a basic thread and its floats prevented the fiber material from participating in later movements of the needles.
  • the pile material to be integrated as catch mesh can also be prevented from uncontrollable movements with the needle by the floating of a lining thread will.
  • the needle path 1 all the needles of a first group of needles are lifted into the catching position and the pile of fibers is combed in by the combing wheel K 1, whereupon the needles return to the concentric position.
  • the needles of the second group are raised according to the needle path 2 into the catching position T 1.
  • a corresponding sinker part has withdrawn the sinkers P, so that a thread guide FF can feed a feed thread below the sinker nose.
  • the sinkers are advanced, whereby the lining thread according to FIG.
  • FIG. 21 A product manufactured according to FIG. 12 is shown in FIG. 21.
  • the thread floats W of the lining threads F.1, F 2, F 3 and F 4 hold the pile material S together with the sinker stitches of the threads G 1, G 2, G 3 and G 4 forming the basic fabric.
  • the properties of the goods can be influenced in a known manner by the lining thread.
