Producing knitwear having stitches from hard, inelastic thread material on a knitting machine provided with knitting needles and holding-down/knocking-over sinkers comprises raising knitting needles at knitting systems to pick up threads, taking down the raised knitting needles into an intermediate position to pre-form the picked-up threads over the sinkers to form loops of pre-selected lengths, and forming the stitches by drawing down the knitting needles from the intermediate position into a lowermost position and raising the sinkers in an opposite direction. An independent claim is also included for a knitting machine comprising a support, in which knitting needles (2) and holding-down/knocking-over sinkers (3) are disposed alternately beside one another, and knitting system(s) (8a, 8b), having a raising cam (22, 23) to raise the knitting needles, tread guide(s) to lay a thread into the raised knitting needles and a stitch-formation section with cams to assign opposite movements to the knitting needles and the sinkers to form stitches from the laid-in threads, wherein the butting system has between the raising cam and stitch-formation section a specific drawing-down edge (27a) drawing a raised knitting needle down into an intermediate position to form thread loops over the sinkers.

Description

The invention relates to a knitting machine and a method to be carried out thereon for the production of knitwear having stitches, in particular of hard, inelastic thread material, using knitting needles and these associated include / tee boards.

The need for technical, knitted or made from knitwear Textiles are increasing more and more. This also applies to knitting machines, knitted fabrics, in particular circular knitting machines, on the other hand for Products made of hard, little or not elastic thread materials such. B. spun metal wires made of staple fibers, monofilament, e.g. B. made of copper or Brass-made continuous wires or the like. Are manufactured. One so far not The avoidable disadvantage is that such thread materials Knitting machines can only be processed with difficulty and especially at higher ones Processing speeds often lead to thread breakage.

It has therefore been known for a long time (DE-PS 516 317) for processing hard To provide a circular knitting machine in which the threads in front of the actual stitch formation (Kululation) over additionally existing inclusion and Teeing boards are preformed into loops. This preforming takes place in that the knitting needles after the thread take-up in an intermediate position be pulled off to the threads thereby over assigned high sinker edges to lay or to draw. At the same time, the boards are preferably in raised in an opposite direction to preform the loops with perform the needles and sinkers together. Following this, the formed loops transferred to the tapping edges of the boards, whereupon the The usual stitch formation takes place by a further deduction of the knitting needles alone. The advantage of the thread material which is made possible by the preforming Preparation of the stitch formation has the disadvantage that neither Length of the preformed loops still changed the size of the stitches formed can be. In addition, no patterns can be made.

The preforming of threads into loops is also used in the manufacture of knitting machines of plush goods generally known (e.g. DE 31 45 307 C2, DE 40 33 735 C2). The The length of the basic thread loops can thereby be made adjustable (e.g. DE 41 29 845 A1) that the basic threads are laid over special drawing edges of boards and then the boards with the help of adjustable lock parts of different distances be advanced radially. In contrast, the plush threads on the same machine placed over the top edges of the boards and with the help of adjustable lock parts subtracted from the knitting needles to different depths. This results in a comparatively complicated machine design used for the production of While plush goods can be justified, mostly thread-making Knitwear made of metal threads or the like. But would be too expensive.

There are also processes and circular knitting machines suitable for their implementation known (DE 33 11 361 A1), which work with the so-called relative technology and themselves characterized by the fact that the knitting needles and inclusion and knock-down boards during mesh formation (opposite) Carry out movements. On the one hand, this makes the use of less steep Lock parts for the knitting needles and sinkers possible. On the other hand, with higher speeds can be worked without the risk of thread breaks consists. In principle, such circular knitting machines would therefore also have to gentle processing of inelastic threads. In addition, the additional advantage can be used that with relative technology there is the possibility to form stitches of different lengths and / or make patterns depending on requirements (DE 33 48 030 C2, DE 34 33 290 C2, DE 39 28 986 C2). That stands however the disadvantage compared to that such knitting machines do not preform the Allow threads to loop.

Based on this prior art, the present invention is technical problem, the process and the knitting machine of the beginning designated genera to make it suitable that with little technical Effort and with extensive protection of the thread material used knitwear with different mesh sizes and with patterns if necessary can be produced.

The features of claims 1 and 5 serve to solve this problem.

The invention makes it possible for the first time to take advantage of the preculation with To combine advantages of the so-called relative technique. This combination will according to the invention also with simple constructive means and without giving up an optional change in the stitch length or the creation of binding patterns achieved in particular by the three-way technique (knitting, non-knitting and catch) are possible. The decisive factor for this is that, according to the invention, if there is a need for a sample, then the preculation takes place and at the end the stitch formation using the relative technique he follows.

Further advantageous features of the invention emerge from the subclaims.

The basic structure of a circular knitting machine according to the invention is shown in FIG. 1 to 3 using the example of a circular knitting machine and one currently considered the best Embodiment shown. The circular knitting machine contains a carrier 1, z. B. a conventional needle and sinker cylinder in a lower area Axially parallel guides has between the knitting tools in the form of z. B. Knitting needles 2, here in particular latch needles, parallel to the axis of the carrier 1 are slidably mounted. In an upper area is the carrier 1 with others Provide axially parallel guides, between which the usual containment / knock-off boards 3 are stored. The boards 3 can be moved parallel to the axis of the carrier 1 stored and can also transverse to the usual radial inclusion movements carry out. The sinkers 3 have the same pitch as the needles 2 arranged in the carrier 1, but are with the needles 2 on gap, so that one Board 3 comes to rest between two needles 2.

The carrier 1 is in a machine frame, not shown, on a Support ring 4 supported and with its axis coaxial to a not shown here vertical machine axis. The support ring 4 is together with the carrier 1 rotatably mounted about the machine axis and with an outer ring gear 5 provided which is engaged with a drive pinion, not shown, which of a drive motor of the circular knitting machine can be rotated.

In a stationary support ring 6, a base plate 7 is attached, on which the carrier 1 surrounding stationary lock casing 8 is mounted. There are 8 on this lock casing lock parts 9, 10 and 11a facing carrier 1, explained in more detail below, 11b, the feet 12 of the needles 2 and 14 projecting radially outward and 15a, 15b of the circuit boards 3 cooperate. The arrangement is corresponding the so-called relative technology so that the needles 2 and 3 boards to Purpose of stitch formation with the help of feet 12, 14 and lock parts 9, 10 in parallel Movements to the machine axis, but in opposite directions can execute. In addition, the circuit boards 3 can additionally by means of the feet 15a, 15b and lock parts 11a, 11b can be pivoted radially to the carrier 1.

Furthermore, the circular knitting machine has a plurality of brackets 16 which are supported by means of supports 17 are supported on the support ring 6 and carry a thread guide ring 18, of which Hang thread guide 19, by means of which threads, not shown, are known in a conventional manner Way raised needles 2 can be supplied.

Circular knitting machines of this type are generally known (e.g. DE 33 11 361 C2 and DE 39 28 986 C2) and therefore do not need to be explained in more detail.

As particularly shown in FIGS. 2 and 3, the needles 2 of a circular knitting machine according to the invention each have a foot 12a, 12b, 12c and 12d, hereinafter referred to as a selection foot, in one of four planes lying one above the other. In a middle plane, each needle 2 is also provided with a foot 20, hereinafter referred to as a knitting foot. Correspondingly, on at least one knitting system, preferably on a plurality of knitting systems, the lock casing 8 has a first segment 8a serving for needle selection and a second segment 8b serving for stitch formation, with segment 8a in the direction of rotation of the carrier 1 (arrow v in FIG 3) is arranged in front of the segment 8b.

As can be seen from FIG. 3, the segment 8a cooperates in particular with the selection feet 12a to 12d of the needles 2 and, for this purpose, has four needle tracks 21a to 21d, one above the other and formed by lock parts, instead of the lock part 9 in FIG. The needle paths 21a and 21d are expulsion paths and are delimited from below by an expulsion part 22, which lifts needles 2 with the selection feet 12a and 12d to a fully extended knitting position. The needle track 21b acts on the selection feet 12b, is delimited on the underside by an expulsion part 23, which lifts the associated needles with selection feet 12b into a catching position, and is also an expulsion path. The needle path 21c is a continuous path and has a lock part 24 which guides needles 2 with the feet 12c in such a way that they remain in a continuous or non-knitting position. In the area of the knitting feet 20, the segment 8a has a recess 25 which is so large that the knitting feet 20 remain unaffected regardless of which of the selection feet 12a to 12d the associated needle 2 is provided with. Otherwise, the needle tracks 21a to 21d each end in the direction of the arrow v at a height which is above the height corresponding to the passage height which they have at the beginning of the segment 8a, as can be seen in FIG. 3. This serves for the correct transfer of the knitting needles 2 when changing from segment 8a to segment 8b.

According to FIG. 3, segment 8b has a needle path 26 assigned to knitting feet 20. This is delimited from above in a section adjoining the segment 8a by a first deduction or precuring part 27 and then by a second deduction or finishing section 28 following this. First pulling part 27 has, as shown in particular in FIG. 3, a pulling edge 27a and then a holding edge 27b adjoining in the direction of arrow v , which runs essentially horizontally and the associated knitting needles 2 with their knitting feet 20 in a position between the catch position and leading intermediate position. The two edges 27a, 27b are formed in the exemplary embodiment for the sake of simplicity on a single lock part, although they could also be attached to two adjacent lock parts.

According to the invention, the trigger part 27a is assigned an eccentric 29 (FIG. 3) which is attached to a pivot pin 30 passing through the segment 8b. At one end of the pivot pin 30, which is accessible from the outside of the segment 8b, an adjusting knob 31 (FIGS. 1 and 2) is fastened, with which the first trigger and pre-pusher part 27 and in the exemplary embodiment with it the trigger edge 27a and the retaining edge 27b parallel to Machine axis (arrow w in Fig. 3) can be adjusted up or down. In the circular knitting machine according to the invention, on the other hand, the second take-off and finishing section 28 is preferably arranged in a stationary manner and is therefore not adjustable. Viewed in the direction of arrow v , it preferably initially contains a pull-off edge 28a, only indicated in FIG. 4, which at the end of segment 8b merges into a substantially horizontal section 28b and then into a slightly rising section 28c, which relaxes serves newly formed meshes.

3 that the needle paths 21a to 21d and 26 so far as possible by counter-lock parts that the lock parts 22, 23, 24, 27 and 28 with a distance corresponding essentially to the height of the respective feet 12, 20 stand opposite, are formed as closed needle tracks around the needle feet 12, 20 even at very high speeds of the carrier 1 safely and almost positively to be able to lead. In addition, the lock parts 22, 23 and 24 are preferably lightweight interchangeably attached to the segment 8a so that the feet 12 depending on desired pattern different lock parts can be assigned.

The boards 3 are according to FIGS. 1 to 3 except with the feet 14 and 15a, 15b each provided with a sinker head 33, which in the usual way has a tapping edge 34, a throat 35 intended to enclose the stitches and an upper edge 36 has, on a board section delimiting the throat 35 from above is trained.

The feet 14 of the sinkers 3, hereinafter referred to as expulsion feet, cooperate in the area of the lock segment 8a with a through path 37 which runs in a horizontal plane and leaves the sinkers 3 unaffected. In the region of the segment 8b, this continuous path 37 is initially continued by a path section 38 to a point which is in the direction of the arrow v shortly before a point at which the holding edge 27b ends. The web section 38 is then adjoined by a web section 39 which is delimited from below by an expulsion part 40 and lies essentially in the direction of the arrow v where the extraction part 28 has its extraction edge 28a (FIG. 4). Finally, the drive-out part 40 is followed by a path section 42 formed by a continuous part 41, which is arranged essentially where the wedge part 28 has its horizontal section 28b.

According to the invention, the ejection part 40 is assigned an eccentric (not shown), analogous to the trigger part 27, which is attached to a pivot pin which projects through the segment 8b. At one end of the pivot pin, which is accessible from the outside of the segment 8b, an adjusting knob 43 (FIGS. 1 and 2) is fastened, with which the drive part 40 can be adjusted upwards or downwards parallel to the machine axis (arrow w in FIG. 3) , The lock part 41 is, however, arranged to be stationary. It also follows from FIG. 3 that the circuit board tracks 37, 38, 39 and 42, analogous to the needle tracks, are preferably designed as closed tracks by corresponding counter-lock parts. A section of the segment 8b formed by the web sections 39, 42 on the one hand and the second take-off or finishing part 28 on the other hand is referred to hereinafter briefly as the stitch formation section.

The webs adjoining the needle webs 21a to 21d in the segment 8b are there, where the selection feet 12a to 12d are acted on, with sufficiently large ones Provide recesses so that the selector feet 12a to 12d with the help of the Knitting feet 20 caused needle movements do not cause collisions and im Segment 8b remain unaffected (see e.g. a recess 45 in the extension the track 21d).

The feet 15a, 15b of the plates 3, which are referred to below as swivel feet, act with the associated swivel lock parts 11a, 11b (Fig. 1) together and become for this purpose, along corresponding paths through the segments 8a, 8b. There the resulting radial pivoting of the plates 3, among other things from the Document DE 39 28 986 C2 is known, which is hereby incorporated by reference The disclosure of the present application is made in more detail Description of the lock parts 11a, 11b dispensed with.

The various components of the circular knitting machine described are designed in this way and so arranged relative to each other that the following with reference to FIGS. 4 to 15th described mode of operation is possible.

In Fig. 4 a knitting system formed by the segments 8a and 8b (Fig. 3) is shown schematically and enlarged. In this case, those lines 46 to 48 are indicated with solid lines, on which hooks 2a of the needles 2 can be guided under the control of the lock parts 22 to 24 according to FIG. 3. Furthermore, a path 49 is indicated by a dashed line, on which the tapping edges 34 of the sinkers 3 are guided under the control of the paths or path sections 37, 38 or the drive parts 40, 41 according to FIG. 3. The movements take place on the one hand in the direction of arrow v and on the other hand perpendicular to it in the direction of arrow w. Finally, a path 50 of the board heads 33 is indicated in the upper region, which are pivoted radially to the machine axis in the direction of an arrow x by means of the feet 15a, 15b of the boards 3 and the lock parts 11a, 11b according to FIG. 3.

It is initially assumed that all selection feet 12a to 12d in FIG Expulsion part 22 is assigned. All needles 2 therefore follow the line I - I in Fig. 4 entering the knitting system segment 8a of the web 46 so that they are first driven out to a line IV - IV in Fig. 4, when passing the Thread guide 19 pick up a thread 51 and then up to line V - V in FIG. 4 are pulled off again somewhat along a track section 52. The old mesh initially lie in the hooks closed by tongues 2b of the knitting needles 2 2a and in the throats 35 of the boards 3 (Fig. 5 and line I - I in Fig. 4). At the Expulsion of the needles 2 into the highest position (Fig. 8 and line IV - IV in Fig. 4) The old stitches then gradually slide under the opening tongues 2b the needle shafts, so that the new thread 51 when passing the thread guide 19 in the open hook 2a can enter. Due to the partial withdrawal of the needles 2 lengthways of the web section 52, the tongues 2b are closed again by the old meshes.

The needles 2 now reach the area of the first trigger and pre-curling part 27 and its holding edge 27b (FIGS. 3 and 4). Is the trigger part 27 by means of Eccentric 29 set in its highest position, then follow the needles 2 between the lines V - V and VIII - VIII in Fig. 4 of a dash-dotted track 27b1. The Trigger edge 27a is practically ineffective, so that the needles 2 are from FIG. 9 apparent and when reaching the trigger part 27 existing intermediate position in essentially retained and therefore the thread 51 only with comparatively short Loops 53 is drawn over the upper edges 36 of the boards 3 (Fig. 9 and line V - V in Fig. 4). However, the deduction and pre-processing part 27 is at its deepest Position set, then the needles 2 follow one shown in solid line in Fig. 4 Path 27a2 - 27b2, whereby the new thread 51 over the upper edges 36 is comparatively long loops 54 is drawn (Fig. 10 and line VI - VI in Fig. 4).

Of course, by means of the eccentric 29, everyone between FIGS. 9 and 10 can also be used possible loop lengths can be set continuously.

In the further course, the needles 2 remain in those shown in FIGS. 9 and 10 Intermediate positions so that the preformed loops 53 and 54 until they are reached the line VIII - VIII in Fig. 4 remain essentially unaffected.

Approximately from a line VII - VII and until a line IX - IX is reached in FIG. 4 there is a radially outward pivoting of the previously radially to inside pivoted boards 3, which is due to a common effect of the swivel feet 15a, 15b and pivot parts 11a, 11b (Fig. 1) is brought about. This will cause it to slip the previously preformed loops 53 and 54 gradually from those for preforming (Preculation) used upper edges 36 on those of the stitch formation (finished formulation) serving tapping edges 34 of the boards 3, as in Fig. 11 for the area the line IX - IX in Fig. 4 is indicated.

At the same time, the needles 2 and sinkers 3 run into the stitch formation section of the Lock segment 8b, which is approximately between lines VIII - VIII and XI - XI in Fig. 4 and is defined by the lock parts 28, 40 and 41 (Fig. 3). As a result, the boards 3 are driven out axially parallel on the one hand on the other hand, the needles 2 withdrawn axially parallel, thereby the old stitches over the newly formed loops 53, 54 knocked off and new stitches 55, 56 (Fig. 12 or 13) formed (finished formulation) until approximately the line X-X in FIG. 4 is reached. Around ensuring a good shape of the new mesh 55, 56, it will Expulsion part 40 is set as precisely as possible by means of the adjusting knob 43 (FIG. 1), that the combined withdrawal and expulsion movements of the needles 2 and sinkers 3rd as precisely as possible of the length of the loops 53, 54 set during preforming (Fig. 9, 10) correspond. Therefore z. B. when finishing the loop 53 a comparatively low expulsion height selected for the expulsion part 41, so that the Boards 3 are guided along a continuous path section 42a (FIG. 12 and line X-X in FIG. 4), while when finishing the loops 54 a greater expulsion height selected according to a dashed path section 42b (see FIG. 13 and line XI-XI in FIG. 4). After that, the educated Stitches 55 and 56 slightly relaxed along the path section 28c of the needles 2 (Fig. 14), so that the needles 2 again their starting positions as in line I - the Fig. 4 take. The sinkers 3 are also at the end of the knitting system (Fig. 15 and Line XII - XII in Fig. 4) have been returned to their starting position, which they too had taken at the entry into the knitting system (line I - I in Fig. 4). The described type of stitch formation can therefore in a subsequent knitting system be repeated.

The type of preculation according to the invention is in particular from FIGS. 16 to 18 seen. 17 shows the pre-formulation of the short loops 53 (cf. also Fig. 9) and Fig. 18, the formation of the long loops 54 (see also Fig. 10) accordingly a dimension x1 or x2, which by the distance of the upper edges 36 of the Boards 3 is determined by the needle hooks 2a holding the loops 53, 54. The maximum loop length x2 (Fig. 18) is due to the location of the old stitch the tapping edge 34 determines that the hooks 2a are only as deep during the pre-formulation be subtracted so that they remain in the old mesh, that is not be knocked off, otherwise a new stitch would already be formed. In the loop length is also advantageously adjustable by a single one Lock part, namely the first deduction and pre-part 27 set.

19 to 21 show, analogously to FIGS. 16 to 18, the process of finishing the transfer of the loops 53, 54 to the tapping edges 34 of the circuit boards 3 the combined axis-parallel movement of the needles 2 and sinkers 3 should be chosen in this way be that in the stitch formation between the tapping edges 34 and Needle hooks 2a the same distances x1, x2 as in the pre-formulation between the Upper edges 36 and the hook 2a result. The advantage here is that the Mesh length determined by a single lock part, namely the expulsion part 40 becomes. Although there are others to measure the loop and loop lengths Opportunities are given, the solution described is preferred because with comparatively simple constructive means can be realized and a comparatively simple and quick adjustment by the operating personnel.

3 and 4 show, selected needles 2 can also with the help of the lock parts 23, 24 are influenced in segment 8a, so that in FIG. 4 they are the catching or non-knitting web Go through 47 or 48. When traversing the trajectory 47 (Fig. 7 and Line III - III in Fig. 4), the needles 2 also take up the thread 51, so that the Precuring is carried out in the same manner as described above. In contrast, when passing through the web 48 (Fig. 6 and line II - II in Fig. 4) the Thread 51 is not inserted into the needle hook 2a, but over the relevant one Boards 3 placed. The needles 2 moved on the web 48 are, however, in the Line V - V of FIG. 4, like the other needles 2, the first withdrawal and pre-processing part 27 fed.

In FIG. 23, in comparison to the case described above from FIG. 22, in which all needles 2 form a stitch, a float pattern is shown. It is assuming that in Fig. 3 three consecutive needles 2 in one Passed track 21c and z. B. three of the four needle tracks 21a to 21d can be realized by a continuous part 24. Against every fourth needle 2 through a knitting track 21a, which is defined by an expulsion part 22. The Knitwear obtained with this type of knitting is characterized in that according to FIG. 23 only on every fourth needle 57 a stitch 58 is formed and in between over three Needles 2 extending floats 59 arise.

Since the preformed loops 53, 54 have to be transferred from the upper edges 36 to the knock-over edges 34 of the sinkers 3 before the stitch formation according to FIG. 11, the thread parts 51a located behind the last knitting needle (e.g. 57a in FIG. 23) are directly connected to a thread section 51b coming from the thread guide 19. Therefore, if the next knitting needle (e.g. 57b in FIG. 23) picks up the thread 51 at the very moment when the loop to be processed by the needle 57a slides from the upper edge 36 onto the tapping edge 34 of the relevant board 3, then there is a risk that the preformed loop will regress and be at least partially pulled into the new loop via the floatation. This creates errors that are visible in the finished knitted fabric. In order to avoid this, it is provided according to the invention that the holding edge 27b (corresponding to the distance of the lines V-V and VIII-VIII in FIG. 4) between the expulsion part 22 and the second draw-off part 28 has a certain minimum length L (FIG. 23) give. This length L is preferably chosen to be so large that there is at least one needle 57a, preferably two or three needles 57a, 57c and 57d, which have already formed a pre-formed loop 58 before another needle (here, for example, 57e) is used Loop formation is used. Conversely, the length of the floatings is chosen to be smaller than the length L. This ensures that the loop located in each case in the transition from the upper edge 36 to the tapping edge 34 of the circuit board 3 (eg needle 57e in FIG. 23) cannot be removed by pulling from the next knitting needle 57b. In the exemplary embodiment in FIG. 23, the holding edge 27b has a length L for this purpose which corresponds to a multiple, preferably at least 12 times a needle spacing.

The invention is not limited to the exemplary embodiments described, which are based on can be modified in many ways. This applies particularly to those in the Individual choice of path for the various needle and sinker feet, because there are numerous different options. For example could the first trigger part 27 be formed so that its trigger edge 27a to extends to the point at which the knitting needles 2 reach their highest position, and therefore also contains section 52 in FIG. 4. Also the arrangement of the feet 12 the needles 2 are arbitrary per se, although it is preferred to use the feet 12a to 12d in Let carrier 1 alternately follow each other. In addition, the invention not limited to the circular knitting machine described, but can in Corresponding modification also on circular-edge knitting machines, circular knitting machines with stationary support 1 and rotating lock jacket or on flat knitting machines be applied. Also an application of the described Principles on knitting machines with pusher needles are possible. It is clear that everyone these machines also for processing other than metal wires or the like. can be used. Finally, it is understood that the different characteristics also used in combinations other than those described and illustrated can be.
