Definitions
- the invention relates to a circular knitting machine for the production of cutting plush, according to the preamble of claim 1.
- the plush handles are cut open by exposing them to a knife-like sharp cutting edge under tension, which penetrates into the thread material as a result of the tension and thus cuts it.
- the cutting edge can be a continuation of the tapping edge for the plush thread on a plush board which is mounted in a board ring;
- the cutting edge can be provided in a manner shown in DE-OS 2 917 378 on a plush board mounted in the cylinder. The cutting edge is inclined with respect to the direction of movement of the sinkers and thus sets the thread as the pulling movement of the sinker increases, until it is severed above the cutting edge.
- such a cutting edge can be arranged on a plush hook below the hook opening, as can be seen, for example, from DE-OS 27 04 295. Then the bottom of the plush hook formed by the plush hook is fixed by a hold-down device, while the plush hook is driven out for the purpose of separating the plush handle and separates the thread due to the increasing tension. It is obvious that the application of increasing tensile stress to the plush handles to cut them is problematic in many respects and is relatively uncertain in terms of success. For example, a safe cut over a long period of time is only guaranteed if the plush material used is the thinnest, least twisted material with low tensile strength, which is also only very limited stretchable so that the thread is actually cut through the cutting edge.
- a movable knife-like cutting element is arranged between two plush hooks arranged immediately adjacent to one another, which keep the plush thread taut for cutting through the movable cutting element .
- the movable cutting element is provided with an upper oblique cutting edge and is moved upwards between the two plush hooks located in the cylinder between their heads in order to break up the thread stretched there. If considerable wear is still to be feared, the disadvantages described above are nevertheless substantially reduced in the case of such a circular knitting machine, but other disadvantages occur, which will be explained in more detail below.
- the plush handles are separated by the squeezing action of a squeezing wheel.
- the plush handle is formed over a board seated in the dial, the board is then supported from below and a squeezing wheel is applied from above to squeeze the thread.
- plush hooks seated in the dial plate pull the plush handle onto a web on which the thread is ground by a pinch wheel.
- the plush handles are formed over a curved sinker nose and migrate to the rear in the course of the further stitch formation, where they are grasped and ground by a pinch wheel.
- the squeezing or grinding of plush handles can only be used successfully if sufficient time is available. This is only possible on machines with low speeds. Particular problems arise when processing highly tear-resistant yarn.
- the plush handles are transferred to a separate cutting element and cut there.
- GB-PS 813 357 for example, by a correspondingly designed dial or according to GB-PS 849 710 by a displacement wheel, one of the two legs of the plush handle is moved to the other so that a take-over element can be inserted into the plush handle, which acts as a holder for serves the cut.
- Such threading of cutting elements or supports into the plush loops is, however, only possible with coarse machine divisions, since with finer divisions the two parts of the plush handle lie too close together and therefore cannot be brought into the different position with the required certainty.
- the plush handles are cut open using two mutually moving cutting edges.
- it is known from DE-PS 11 53 482 for example, to arrange movable plush sinkers in the dial and to provide at their end behind the plush handle with a projection which carries an upright cutting edge adjacent to the plush handle.
- a knife shank for a fixed counter knife is also arranged for the plush board, which has an upright counter cutting edge on the opposite side of the plush handle. If the plush board is drawn in, it takes the bow of the plush handle with its cutting edge in the direction of the counter-cutting edge and shears it off at the counter-cutting edge.
- a corresponding arrangement is known from DE-PS 1 585 051, the counter knife being slightly bent in the direction of the plush board, and so the counter-cutting edge is resiliently pressed onto the side surface of the plush board in order to avoid a gap between the cutting edge and the counter-cutting edge with greater certainty .
- DE-QS 24 23 700 it is known from DE-QS 24 23 700 to run the shaft of the plush board in a U-shaped knife, which carries two counter-cutting edges on both sides of the plush board at its front end; the one-piece, stable design of the knife should position the two counter-cutting edges cleanly on both sides of the plush board, in order to avoid a gap between the cutting edge and counter-cutting edge when cutting.
- the interaction of a cutting edge with a counter-cutting edge during the movement of the plush sinkers is intended to ensure that - unlike in the first group with only one cutting edge - the cutting forces do not have to be generated by excessive tensile stress on the plush handle, but by relative movement of two cutting edges without any significant additional Tension of the plush handle can be achieved.
- the cutting edges do not need to be designed as drawing edges over which the plush handle scrapes with high tension, so that a cutting concept with cutting edges that can move against one another both reduces wear and prevents the plush thread from wholly or partially being run over the cutting edge is scraped up.
- the disadvantage here is in particular that the plush board and the counter knife, which in the case of DE-OS 24 23 700 is also arranged on both sides of the shaft of the plush board, lie in a common guide channel and must be kept movable relative to one another therein.
- Mutual mobility presupposes that there is no excessive mutual contact pressure.
- the game required for easy mutual mobility on the other hand has a detrimental effect on the cutting process, since then the cutting edge and the counter cutting edge must either have a corresponding mutual play, as in the case of DE-OS 24 23 700, or can be bent away from one another relatively easily Such as in the case of DE-PS 1 153 482.
- the plush board and the counter-cutting board can each be only about 0.25 mm thick. This means that there is no sufficient contact pressure between the two cutting elements, nor is there sufficient stability of the cutting edges, so that such small element thicknesses are impractical in practice. This leads to a corresponding need for a coarser needle pitch.
- a common problem for all known possibilities for cutting open the plush loops integrated into the knitting process is to achieve a uniform stitch pattern, in which the basic thread covers the plush thread on the stitch side by plating.
- the needle stitches are widened by sliding over the needle face and the tip of the tongue, and when pulling out, by pulling through the needle head. Since the needle stitch bows from the basic threads are connected laterally and one above the other with stitches, they then return to their original shape. If, on the other hand, the plush loops are cut immediately after they have been formed, there is no longer any possibility of retensioning the widened loop of the plush thread after the subsequent stitch has been formed. When integrating the plush handles in the needle stitch it is therefore necessary to achieve a smooth stitch pattern that the plush loops remain at least partially stretched until their stitches have been knitted through another row of stitches and no change in the stitches can be made by resting on the moving needles.
- each stitch row is formed only by part of the needles and plush elements; However, this means that only a partial row and not a complete row is generated at each workstation, thus smoothly halving the productivity of the circular knitting machine.
- Each plush handle is only severed by means of a squeeze wheel after the subsequent plush handle has been completely knitted off in the course of shaping the plush handle after that, so that the cut plush handles are then released from the sinker nose and are removed in the course of the goods take-off with the knitted fabric produced so that the goods withdrawal forces are thrown away Let the knitted plush handles slip into the effective area of the crushing wheel.
- the invention is based in the preamble of claim 1 of the circular knitting machine according to DE-OS 2 535 197, in which latch needles are stored in the dial and plush elements in the cylinder, and in which each plush element here consists of two parallel, closely adjacent plush hooks - each a relatively movable cutting member for cutting the plush handles is assigned.
- each plush element here consists of two parallel, closely adjacent plush hooks - each a relatively movable cutting member for cutting the plush handles is assigned.
- the invention has for its object to provide a circular knitting machine of the type specified in the preamble of claim 1, with which, in case of need of fine machine division, a commodity construction can be made by knitting basic and plush threads together without disturbing the stitch formation by the cutting process .
- the plush elements Due to the fact that the plush elements have a cutting edge arranged at a distance below the plush formation area, the cut of each plush arm takes place according to the selected distance between the plush formation area and the cutting edge, possibly with a delay, only after at least one plush arm lying behind the plush arm to be severed together with the basic thread is knitted.
- This aspect corresponds essentially to the concept known from GB-PS 891 973 of avoiding the influence of the stitch formation process by the cutting process in that the cutting process is delayed compared to the stitch formation process and can therefore no longer adversely affect the stitch formation process.
- the cutting edges of the plush elements are upright, that is to say arranged essentially parallel to the axis of the cylinder and cooperate with counter-cutting edges of the cutting element.
- the plush elements therefore do not simply serve to tension the plush thread for the cutting edge of the knife-like cutting process, but rather form a cutting edge itself which interacts with the cutting edge of the cutting member as a counter cutting edge.
- the movement of the cutting member runs in the direction transverse to the longitudinal extent of the cutting edge, that is transverse to the axis of the cylinder, and not parallel to it as in the case of DE-OS 2 535 197.
- Both the distance between the plush formation area on the one hand and the upper end of the cutting edge on the other hand, as well as the length of the cutting edge of the plush element and the substantially corresponding length of the shear bar of the cutting element, can be dimensioned sufficiently so that a plurality of initially uncut plush legs initially exist above the cutting edge and then reaches the area of the cutting edge.
- the distance between the upper end of the cutting edge and the plush formation area is to be chosen regularly so that the plush thread is integrated in such a way that a retensioning of the to achieve a smooth stitch pattern previously formed stitch is possible, so the cut is delayed in the manner described.
- This is also advantageous in the case of a catch, in order to counteract warping of the plush loops, but not always necessary; rather, the distance between the puddle area and the cutting edge can be reduced so far that the cut is made immediately after the plush handle to be cut is formed.
- the distance should be chosen with the aim of fine machine division so that the cut is made at the cutting edge below the plane of the needles, so that the mutual distance of the needles need not be increased for the cut.
- each plush handle is cut immediately as soon as it comes into the axial area of the cutting edge of the plush handle and the cutting cycle is carried out, but this also results in redundancy that prevents malfunctions even in the event an impairment of the cutting action, for example due to wear, since an uncut plush handle can move on the cutting edge and is then repeatedly exposed to the influence of the interaction between the cutting edge and the shear bar at the same point on the arch of the handle.
- the cutting movement can only take place intermittently after a plurality of rows have been knitted off, in order then to grasp a corresponding number of plush loops present together on the cutting edge, so that the redundancy described can be partially eliminated in favor of reducing the number of cutting movements .
- a circular knitting machine according to the invention in the usual way has a cylinder Z, in which plush elements 1 are held, and one not shown in FIGS. 1 and 2, but in FIGS. 4 , 12 and 13 indicated dial R, in which needles N designed as conventional latch needles are horizontally movable.
- dial R in which needles N designed as conventional latch needles are horizontally movable.
- a knitted fabric G is produced with the needles N and is drawn off on the inside of the plush elements 1 and the cylinder Z in the direction of the longitudinal extent of the plush elements 1, according to the arrow W drawn therein, the plush elements 1 with their plush formation areas designed as pulling hooks in cooperation with the needles N by pulling back during stitch formation into a position as shown schematically in FIG. 2, produce plush handles H on the outside of the knitted fabric G, as is known per se.
- the needles N are supported at a corresponding distance above the upper end of the cylinder Z.
- the plush elements 1 in the corresponding guide channels of the cylinder Z can be actuated M if necessary. Otherwise, the vertical movement of the plush elements 1 takes place by means of corresponding lock parts via a foot 1d.
- Each plush element 1 is assigned a cutting element 2, which is arranged in the same plane as the plush element 1 in the same shaft 2a and which has a thickness corresponding to the plush element 1.
- the cutting member 2 has a cutting head 2b with a counter cutting edge 2c which, in the manner explained in more detail below, lies at the level of the cutting edge 1c of the plush element 1 and cooperates with it.
- the cutting head 2b is bent out of the plane of the shaft 2a via an offset 2d and lies laterally next to the plush element 1 in the region of the cutting edge 1c thereof. If the plush element 1 is retracted in its guide channel in the cylinder Z in the manner shown in FIG.
- the cutting member 2 pivots away with its cutting head 2b and thus lies above the guide channel, which is indicated at FK.
- the cutting head 2b is either in the position shown in FIG. 1 above the cylinder Z and thus the guide channel FK, or in the position shown in FIG. 2 radially outside the guide channel FK, so that its width only corresponds to the thickness the plush element 1 or the shaft 2a of the cutting member 2 needs to be dimensioned.
- the latter In order to achieve the pivoting movement of the cutting element 2, the latter is held so as to be pivotable via a driver head of the plush element 1 and a driver opening 2e of the cutting element 2, which engages around the driver head le in a round contact surface, and is thus displaced vertically together with the plush element 1.
- horizontal pressure lock parts On the feet 2f and 2g of the cutting element, horizontal pressure lock parts, not shown, act to selectively pivot the cutting element 2 back and forth between the positions shown in FIGS. 1 and 2.
- the counter-cutting edge 2c on the cutting-blade-like cutting head 2b is, as will be explained in more detail below in connection with FIGS. 4 to 7, both inclined at an angle to the cutting edge 1c of the plush element 1 and crossed, so that when the counter-cutting edge 2c passes the cutting edge 1c when transferring the cutting head 2b from the position according to FIG. 2 to the position according to FIG. 1 in the manner known from scissors to obtain an exclusive point contact under mutual pressure, which ensures a clean severing of the plush handles H in the area of the cutting edge 1c. Since the entire force required for the cut is generated by pressurizing the feet 2f and 2g of the cutting member 2, no thread tension of the plush handle is required for cutting.
- the needles N and the plush elements 1 are driven out to form stitches.
- the plush elements 1 are advantageously driven out in front of the needles N in order to prevent movement of the knitted fabric G with the needles N by being supported thereon.
- the plush elements 1 are driven out to such an extent that they are guided through the plush handles H with their clamping arches 1b.
- the plush elements 1 are withdrawn somewhat, so that the plush loops adjacent to the tensioning arches 1b pull any previously widened loops of the plush thread onto the needle shaft.
- Previously formed plush handles H slide further downward in the course of the manufacture of the goods and reach the effective area of the cutting edge 1c which is arranged upright on the plush element 1 and is at a distance a from the plush formation area 1aa.
- the cutting pivotal movement of the cutting member 2 is generated over the foot 2f of the cutting member 2 and a corresponding pressure lock part, so that the counter-cutting edge 2c is entangled on the cutting edge 1c and thereby plush handles H present in the area there are cut.
- the knitted fabric G is released from the plush elements 1 and can contract and be pulled further in the direction of the goods take-off W.
- Fig. 1 the position at the end of the cut is illustrated.
- the cutting edges 1c and 2c are arranged in such a way that at least the plush handles H of the last two rows formed are retained as loops for re-tensioning. This later enables the tensioning of stitches drawn over the needle head.
- the needles N are brought into the thread-laying position.
- base and plush threads can now be fed in at about the same time, after which the needles N and the plush elements 1 are withdrawn until the position according to FIG. 2 is reached.
- the cutting member 2 should be pivoted back into the position according to FIG. 2 by means of a pressure lock part via the base 2g, so that it is possible to guide the plush elements 1 precisely with a cylinder which extends as far up as possible. without the cutting heads 2b getting into the guide channel FK.
- the embodiment described above has the advantage that a cutting movement takes place only when the formation of a plush handle H is provided, so that unnecessary cutting movements are omitted if a corresponding pressure lock action on the foot 2f of the cutting member 2 does not take place.
- a plush element 1 may only remain inactive for a few rows or it must be ensured that the plush handles H are cut regularly by own cutting systems in which all the plush elements 1 but no needles N are expelled.
- the needles N according to curve NV, the plush elements 1 with the cutting members 2 axially mounted thereon according to curve V and the cutting movement of the cutting members 2 according to curve Vla can be controlled according to FIG. 3, the curve Va indicates the position of the cutting edge 1c, which cannot be changed in the radial direction. As previously described, all the plush elements 1 are fully driven out and pulled back a little for retensioning. A selection device begins shortly before the end of the cutting movement with the withdrawal of the plush elements 1 not provided for forming plush loops according to curve Vs.
- the cutting elements 2 instead of taking the cutting element 2 on the plush elements 1 by means of its driving head le in the axial direction, it is also possible for the cutting elements 2 to rest only loosely on the plush elements 1 and to always keep them at the same height, so that they only have the pivoting movement required for cutting carry out and the cutting head 2b always remains above the cylinder Z.
- the cutting element 2 can rest on the radially outer narrow side of the shaft of the plush element 1; alternatively, however, the shafts of the plush elements 1 can also be widened such that they protrude radially from the associated guide channels FK and form their own guide channels between them, in which the shafts 2a of the cutting members 2 can be arranged without this widening the guide channels FK in Requires circumferential direction of the cylinder Z and leads to a coarser machine division.
- a major advantage of the arrangements explained is that even with fine machine divisions, sufficiently stable plush elements 1 and cutting elements 2 can be provided.
- the arrangement of the two elements on top of one another can be provided, with a corresponding widening of the guide channel FK.
- the knitted fabric G is drawn off parallel to the plush elements 1 by the stitch formation in the dial R. There is therefore no need for any further aids in order to gradually lead the plush handles H down from the plush formation area 1a into the area of the cutting edge 1c.
- the distance of the cutting edge 1 from the underside of the needles N seated in the dial R or from the plush formation area 1 a - depending on the row density - can roughly determine the number of further rows after which the plush handles H enter the cutting area. Since the plush handles H cannot leave the plush element 1 between them, but are at least partially held under tension by them, the correct plating position of the base and plush threads relative to one another is also ensured.
- the described embodiment requires a very long plush element 1 and a relatively complex control of both the plush element 1 and the cutting element 2 because of the illustrated assignment of the cutting element 2. Since a vertical movement of the cutting elements 2 is not necessary, the storage of the cutting elements 2 outside the To a certain extent, cylinders instead of boards are made in a guide ring such as a board ring.
- FIGS. 4 to 7 Such an arrangement is illustrated in FIGS. 4 to 7. Since the arrangement of a plate ring for cylinder Z is generally known, these two parts have not been shown in order to improve the clarity of the illustration.
- the plush element 11 there also has a plush formation area 11 a designed as a drawing hook, a tensioning bow 11b and a cutting edge 11c c, while the cutting member 12 there also has a shaft 12a, here guided in the sinker ring, a cutting head 12b and a counter-cutting edge 12c, and a control foot 12f.
- a guide projection 1 h is provided on the plush element in the embodiment according to FIGS.
- a guide projection 12h is provided on the cutting member 12, which secures the desired relative position between the cutting member 12 and the plush element 11 when the cutting member 12 is retracted, and ensures a clean run-up of the cutting edges 11c and 12c on one another.
- the plush elements are controlled vertically by a separate control foot (not shown in more detail) or by a selection device.
- a sinker ring is provided in which the cutting members 12 are mounted instead of sinkers and are driven out or retracted in a horizontally controlled manner via the control foot 12f.
- the front end of the Cutting elements 12 with the counter-cutting edge 12c can be angled in whole or in part to the axis of the plush element 11 in order to obtain an inclination angle ⁇ illustrated in FIG. 5.
- the cutting members 12 are flat or planar for this purpose and are mounted in the sinker ring to form the setting angle ⁇ .
- the shafts 12a of the cutting members 12 are mounted exactly vertically in the sinker ring, but the cutting heads 12b are bent correspondingly with respect to the plane of the shaft 12a and the guide projection 12h, as seen from the top view of FIG Cutting member 12 in Fig. 6 is readily apparent.
- the counter-cutting edge 12c has an angle of attack a with respect to the cutting edge 11c, as can be seen from FIG. 4; this applies to all exemplary embodiments.
- the plush handles H are formed as in the exemplary embodiment according to FIGS. 1 and 2. After forming the last row of stitches, as illustrated in FIG. 4, the plush elements 11 and the needles N are driven out. By appropriately controlling the plush elements 11, the tensioning of the plush handles H takes place through their tensioning arch 11b after the stitches have reached the needle shafts from the needle tongues. While the needles N are now withdrawn in the thread-laying position, the cutting movement takes place by advancing the cutting members 12 via the control foot 12f by means of corresponding lock parts, as is illustrated in FIG. 7. Before or during the feeding of basic and plush threads. behind the plush element 11, the cutting member 12 is withdrawn again.
- the needles N and the plush elements 11 are completely retracted to form loops or loops, as can be seen again from FIG. 4.
- Appropriate arrangement of the cutting members 12 below the needles N ensures that at least the plush loops H of the last stitch row formed are not cut immediately.
- the needles N, the plush elements 11 and the cutting members 12 are preferably controlled in accordance with the movement sequence described previously in connection with FIG. 3.
- the plush handles being integrated as catch stitches, which is not necessary, but is certainly possible in the manner described below.
- a part of the needles N according to curve NI becomes, and all plush elements 11 according to curve V are driven out. Since re-tensioning is not necessary when the plush handles H are tied in, the cutting movement of the cutting members 12 can take place at such a small distance a below the level of the N that the plush handles H are cut immediately after formation. then plush elements 11 not provided for receiving the plush thread P are withdrawn according to curve Vs, while the needles N are driven out into their position required for forming the plush loop.
- the plush thread P is now fed by the plush thread guide FP to the plush elements 11 which are still driven out, whereupon these are withdrawn according to curve Vp for loop formation.
- the plush elements 11 are no longer in the area of the needles N, at least some of the needles N which have previously remained in the roundness can be brought into the knitting position according to curve N2 and / or into the catching position according to curve N3.
- Predetermined needles can remain in the concentric position according to curve N4.
- the basic thread guide FG feeds the basic thread. Then all needles are pulled back to form stitches.
- the plush elements 11 can be dispensed with for the production of unpatterned (smooth) cutting plush goods
- the plush elements With a plush formation area, the plush elements then protrude between the expelled needles N in the dial R.
- the distance between the plush formation area in the form of a contact surface of the plush elements for the plush thread when the plush legs are formed and the tapping edge of the dial disc determine the length of the plush legs H.
- a change in the handle height can be achieved by changing or predetermined use.
- such an embodiment has the advantage that no cylinder locks are used Movement of the plush elements are required.
- the cutting process is largely independent of the stitch formation process, in the case of fixed plush elements at all.
- the movement of the cutting members 2 and 12 should take place with the least possible movement of the plush elements 1 and 11, i. H. preferably in their concentric or driven position.
- a cutting process must be provided at least after forming a few rows of stitches.
- a cutting movement of the cutting elements can only be provided at predetermined work stations or systems of the circular knitting machine. This reduces wear on the cutting edges.
- a cutting movement can also be carried out in the same or predetermined change with only a part of the cutting elements. This also protects the cutting edges.
- it is possible to work with a smaller number of plush elements and cutting elements than knitting tools are arranged. Are each formed only on every fourth needle plush loops and in aufgorifoigenden systems integration into the center offset, whereby each second needle never takes part in the formation of pile loops, so need in the cylinder and Platinenrin g only half of plush elements 1 and 11 and cutting elements 2 or 12 may be stored. Due to the fact that only half as many guides are necessary, they can be wider, which means that stronger plush elements and cutting elements can also be used.
- the plush handles H are looped around the plush element 1 or 11 in such a way that, in the event of malfunctions in the functional sequence due to inadequate abutment of the cutting edges against one another, high tension of the plush handle or other influences, the counter-cutting edge 2c or 12c can be pushed away from the plush handle H. .
- This can be prevented if the plush handles H do not wrap around the cutting edge 1 c or 11 c in contact with the cutting edge 1 c or 11 c by appropriate shaping of the contact surface of the plush element 1 or 11.
- 9 to 11 illustrate two possibilities of how the plush elements 21 and 31 there are formed in two parts, at least in the region of the cutting edge 21c and 31c, the counter-cutting edge 22c and 32c of the cutting element 22 and 32 there, respectively, between the two parts is passed through.
- the plush element 21 consists of two individual parts which lie flat against one another with their flat sides, namely a partial element 21f which is more solid in the example and a thin partial element 21g which are congruent in the side view (not shown).
- Both sub-elements 21f and 21g are shaped in the area of the passage of the cutting member 22 carrying the counter-cutting edge 22c, for example sub-member 21f is recessed and part 21 g is bent so that the cutting member 22 bearing against the cutting edge 21c is passed between the sub-members 21 and 21 g.
- the cutting member 22 is pushed as it passes through the slot 21h remaining between the sub-elements 21f and 21g and also bends out the thin sub-element 21 g. It is therefore advantageous if the partial element 21g rests against the partial element 21f. In the axial region of the cutting edge 21 c, the thin, resilient partial element 21 g is radially set back with respect to the cutting edge 21 c with respect to the cylinder axis, in order to prevent the plush thread from getting caught in the course of the cut on the right-hand side of the cutting element 22 in the illustration according to FIG. 9 .
- the plush thread spans the slot 21 h and is not in direct contact with the wall surface having the cutting edge 21 c, but is spread apart by the latter by the opposite partial element 21 g, so that there are more favorable cutting conditions and pinching of the plush thread between the cutting edges 21 c and 22c is reliably avoided in the case of poor cut.
- the plush element 31 is almost completely formed by the partial element 31f, and the resilient partial element 31g between the cutting edge 31c and the plush formation area 31 is firmly connected to the flank of the partial element 31f, below the cutting edge 31c, however, is supported loosely resiliently.
- excessive shaping of the plush handles is avoided without impeding the movement of the counter-cutting edge 32c and the cutting member 32.
- Due to the corrugated shape of the upper part of the plush element illustrated at 31b the re-tensioning of previously formed plush loops is achieved.
- the front edge of the partial element 31g is also opposite to that Cutting edge 31 of sub-element 31 is set back somewhat, as has already been explained above in connection with the embodiment according to FIG. 9, on the one hand to hold the plush thread over slot 31 h and to spread it away from cutting edge 31 c, but on the other hand on that of cutting edge 31 c opposite side of the cutting member 32 to avoid pinching the cut end of the plush thread on the sub-element 31g.
- FIGS. 12 and 13 illustrate plush elements 41 and 51 which do not have to be moved vertically during operation and how the plush elements work, which are already described in connection with the embodiment according to FIGS. 4 to 7 as an alternative possibility without vertical displacement .
- the plush elements 41 and 51 are expediently pivoted about a pivot point 41 e and 51 e.
- longer plush legs are formed faster because the needles N and the plush elements 41 and 51 simultaneously perform an opposite movement and the movement of the plush elements 41 and 51 is adjustable.
- the plush element 41 is provided with a partial element 41 g, corresponding to the above considerations for FIGS. 10 and 11, and guided radially on the cylinder Z with a guide projection 41 h.
- the plush element 41 is held in its position by a lock ring 9.
- the plush element 41 projects downward from its guide in the cylinder Z with a lower control foot 41f.
- the control foot 41f is guided in a path formed by lock parts 8a and 8b.
- the lock parts 8a and 8b are fastened on a displaceable carrier 8c. By adjusting the lock part carrier 8c, the lock parts 8a and 8b control a different pivoting movement of the plush elements 41. This results in an adjustable pivoting movement of the plush elements 41 in the area of the loop formation, by means of which changes in the handle length of the plush handles can be set quickly.
- the plush element 51 is pivotally mounted in the cylinder Z about the pivot point 51e and has an additional control foot 51d, by means of which the plush elements 51 can also be displaced in the longitudinal axis. Further control feet 51f and 51'f interact with pressure lock parts which pivot the plush element 51 into the position desired for the formation of loops. If the plush elements 51 have control feet 51 d of different heights or different arrangements, then predetermined plush elements 51 of such different design can be used accordingly and can be raised differently, for example higher than plush elements 51 of different design. As a result, the control feet 51'f are also sorted to different heights. Due to the differently acting pressure lock parts, plush handles of different lengths can be formed in a row.
- the plush elements 51 can also be selected by a selection device known per se.
- a selection device known per se.
- the handle lengths are not different Contact surfaces of the plush elements 51 are fixed for each system or each work place, but can be set optionally at each work place.
- selected plush elements 51 can be designed in such a way that the production of loop and cut pile goods is possible in a pattern.
