- a third device of this type ( DE 102 11 231 C1 ) has the knitting needle under the needle hook on a slot into which a horizontally and vertically movable downwardly movable transfer hook is penetrated.
- the front bearing surface of the transfer hook is movable in its relative to the needle hook relative upward movement about the depth of the slot engaging portion of the transfer hook perpendicular to the needle hook.
- the mentioned known devices have as a common feature a downwardly directed transfer hook for holding the last formed stitch through which a new thread is pulled (emulated). This arrangement has several advantages over the usual stitch formation.
- a slider needle which has a slot in its needle breast and at a distance to a recess.
- the needle is associated with a slider having an extension extending into the recess.
- the recess and the extension have sliding surfaces arranged obliquely to the needle longitudinal direction, so that the slider, when moved longitudinally relative to the needle, experiences a sideways movement.
- the slider has a reduced width mesh receiving portion that fits into the needle slot. The mesh receiving portion serves to temporarily hold a loop in stitch formation.
- the object of the invention characterized in claim 1 is to provide a stitching arrangement in which the control of the knitting elements and also the knitting elements for advanced pattern applications are simplified with high performance and safety, and a larger one Stability of the transfer hook with a self-cleaning effect when dipping into the needle slot for the finest needle designs are possible.
- the invention is basically used advantageously for all mentioned machine variants. It offers versatile patterning options even for the finest pitches with the goal of strong knit fabrics.
- a knitting or warp knitting machine can be provided with at least one continuous thread which is looped through the previously formed loop to form the new loop stitch by means of the hook portion of a knitting needle Transverse movement of the transfer hook and the movement of the needle is arranged by arranged at the shaft end and engaging in cam tracks control feet during mutually relative longitudinal movement of the two stitch forming elements is effected.
- the knitting elements are non-positively connected by the coupling elements, by the inward-transverse movement of the upward transfer hook within the needle channel or (in warp knitting machines) below the Abzzikammes during the forward movement is controlled such that after leaving the Kulier ein the needle and release the old stitch from the transfer hook the stitch forming elements are jointly advanced in their upper position, such that the control foot of the Transfer hook over a synchronous increase in the machine lock intercept the coupling impact of the needle.
- the development according to claim 2 facilitates the mesh transfer from the needle breast to the holding section of the transfer hook for the finest needle designs and the controlled lifting the transfer hook from the needle slot with a self-cleaning oblique movement.
- the control feet of the transfer hook defined by the patterning are controllable with a mechanically or electronically operated backward pulse such that by coupling the stitch forming elements Needle hook and transfer hooks perform the required small return stroke together.
- the old stitch can pass from the transfer hook to the new thread inserted in the needle hook before the needle makes its further return stroke, released from the coupling with the transfer hook.

- the stitching assembly may be used on a flat knitting machine having two straight long angled and longitudinally displaceable needle beds which are aligned with their channels during the stitching.
- the transfer hook parts can consist of two parallel lamellae. For the transfer process to the other side of the bed a transfer hook can be moved to the middle of the free opening of both needle beds and then the needle with the hook of the other bed, the transferring stitch and their holding lamellas pierced and expand, so that after the withdrawal of the transferring Transfer hook blades all stitches are on the receiving needles.
- the stitch forming elements can be accommodated in two independently controlled bars of a warp knitting machine and the transfer hook parts can have a slightly prestressed spring area, so that the relative transverse movement of the two bars results in the required transverse movement of the transfer hook due to sliding contact of the loop forming elements.
- Both knitting elements can also be accommodated in a bar and the transfer hook parts can be longitudinally displaced without tension, wherein the relative movement of the transfer hook parts to the needles via a control rail and the transverse movement of the transfer hook or the coupling of both elements by guide recesses and associated finger-like projections on the shaft.
- the oscillating movement of the transfer hooks and / or the needles can be effected in each case by subdivided into sections oscillating systems, which is generated via radial cam, axial cam or rocker arm and transmitted from a control rail on the transfer hook.
- the development according to claim 3 allows the trouble-free coupling of the stitch-forming elements.
- the development according to claim 4 stabilizes the outward position of the transfer hook.
- the development according to claim 5 ensures the transverse movement of the transfer hook.
- the development according to claim 7 is suitable for very fine needle designs and avoids friction losses.
- the Fig. 1 shows the needle 1 with needle shaft 3 and needle hook 2, which has already taken a thread F.
- the upwardly directed transfer hook 12 is arranged with its shaft 11.
- the shaft 3 of the needle 1 has a recess 6 which is connected to the finger-like elevation 16 (FIG. Fig. 2 ) of the transfer hook 12 corresponds.
- the recess 6 on the shaft of the needle 1 terminates at the top with the rising surface 7 and at the bottom with a partially beveled recess 8.
- This sliding surface facilitates in cooperation with the bevel 17 of the likewise bevelled finger 18 (FIG. Fig. 2 ) of the transfer hook shaft 11 the mutual engagement.
- the rising surface 7 in the needle shaft 3 and the bevel 17 in the transfer hook shaft 11 are arranged so that they engage in certain positions of the needle and shaft 11 of the transfer hook 12 in operative connection.
- a recess 8 Below the rising surface 7 in the needle shaft 3 is a recess 8. In relative movements of the needle 1 and transfer hook 12 to each other, these two elements (1 and 12) by the amount x moved away from each other.
- Z shows the vertical movement tolerance of the elements (needle 1 and transfer hook 12) in which the inward position of the transfer hook 12 in the needle face 4 is ensured.
- Fig. 1 begins the transverse movement of the transfer hook 12 characterized in that the shaft 11 of the transfer hook 12 slides with its increase 16 of the rising surface 7 along and leaves the positive connection with the needle shaft 3. In this case, the coupling of both elements (1 and 12) is released.
- the recess 6 In order to obtain the outward position of the transfer hook 12 during the retraction of the needle, the recess 6 must be set back by the amount y (corresponding approximately to the needle path). The old stitch is on the transfer hook 12 located in the area in the needle slot 5 (in Fig. 2 visible) of the needle breast 4 is temporarily performed, lateral settlements 10 has.
- the Fig. 2 shows the Kulier ein of the needle hook 2 with the formed into a new loop thread F, while the transfer hook 12 remains in its upper outward position. Also, the recess 6 and the increase 16 no longer interlock. The old stitch is located just above the tee edge A.
- the stitch formation thus takes place, as in the precursor embodiments, in four, now in three process steps of the two elements.
- the return stroke of the transfer hook 12 which releases the mesh held by him.
- the third phase contains the upward movement steps of the needle 1 and the transfer hook 12, d. H. during the advancement of the needle 1 is a coupling with the transfer hook shaft 11 within the needle channel and then the common feed to the upper position.
- the coupling within the needle channel has the important advantage of safety when immersing the transfer hook 12 in the needle breast 4 and allows the tolerance compensation of existing deviations in the needle channels.
- the advantageous small transverse movement of the transfer hook 12 takes place without control in the needle lock solely by the mutual relative longitudinal movement of the two shaft parts. These are simply structured components in the same shaft thickness without settling and overlapping. The required accuracy can be ensured with today's punching technique, since no bending operation is provided. Typical needle making operations are only necessary in the front part of the hook and the subsequent zashing.
- the invention enables a small increase in the breast, ie small stitches and greater freedom in the design of needle hook 2 to the chest height.
- Fig. 4 shows a new stitch, which has formed by advancing the needle 1.
- the elevation 16 on the transfer hook shaft 11 returned to the recess 6 in the needle shaft 3.
- This coupling action causes the inward transverse movement of the transfer hook 12 into the needle slot 5.
- both elements move together into the upper one Position of the Fig. 1 ,
- FIGS. 1 to 4 located in the rear of the needle shaft 3 as well as in the rear of the shaft 11 of the transfer hook 12 is not shown control foot.
- the last stitch formed is held on the needle face 4 in the holding area of the transfer hook 12 at the tee edge A of the needle cylinder or bed.
- the retraction of the needle 1 begins.
- a transverse movement of the transfer hook 12 occurs, which is lifted out of the needle breast 4, so that the needle hook 2 can be passed smoothly on the transfer hook 12.
- the needle shaft 3 and the shaft 11 of the transfer hook 12 have to the channel bottom K ( Fig. 3 ) parallel bearing surfaces, which complement each other positively in the coupled state. In the front area these are offset by the dimension x of the desired transverse movement of the transfer hook 12.
- FIGS. 5 and 6 illustrate - again enlarged 2 times - the important advantage of the oblique transverse movement of the transfer hook 12 in the needle slot 5, which is especially in fine needle designs of Bedeufung.
- This is located with its holding area b - b ( Fig. 6 ) in a recess 9 behind the needle breast 4.
- DE 10152856 C1 and DE 10211231 C1 is a slight inclination of the transfer hook 12 is required for the transition from the lead to the holding section, which slightly widen the mesh.
- the embodiment of the invention avoids this disadvantage and creates a smooth transition.
- the shaft 11 opens in full strength into the holding region b - b of the transfer hook 12, so that the centering of the tip can easily be carried out for the introduction region a - a.
- the mesh passes without sliding resistance on the holding area b - b.
- the transverse movement of the transfer hook 12 obliquely to the needle 1 is self-cleaning in the needle slot 5.
- transverse movement in a known device DE 2909963 C2
- Fig. 7 which shows a section through the insertion area a - a, as previously suggested, the zipper width can be extended beyond the shaft thickness.
- the Fig. 8 shows a section through the holding area b - b.
- the Fig. 13 concerns the knitting function "catch".
- a new thread F has been inserted into the needle hook 2, by the control foot of the transfer hook 12, not shown, as a result of the coupling both knitting elements (needle 1 and transfer hook 12) so far behind the tee A moved back that the above the transfer hook 12th From this loop slides, resulting in the subsequent stitch formation process accordingly Fig. 1 to 4 the new loop and the old stitch in the needle hook 2 and then get on the transfer hook 12.
- the choice of which needles to make when passing through a lock "catch" happens with known technology by control feet different height, which are assigned in the needle locks cams.
- the invention has further advantages.
- the styling needle In contrast to the now common technology makes the styling needle always the same movement. If a tuck stitch occurs, after insertion of the new thread and before the backward movement of the styling needle, a small return pulse is applied to the control foot of the transfer hook 12, whereby both elements are frictionally guided around the transfer hook length to the rear. The previous stitch thus passes from the transfer hook 12 back into the neck of the needle to the newly introduced thread, which is then copied.
- the invention also makes it possible to control individual needles in a freely programmable manner.
- actuation magnets come with extremely short. Response time to the application, because the time cycle within a needle pitch at the high speeds is minimal, so that very short control movements are a prerequisite.
- FIGS. 14 and 15 show how the driving path can be limited to the order of a millimeter.
- Fig. 14 be after the Austriebswolf ( Fig. 1 or Figure 10 ) with inserted new thread F all needles in the machine lock on the not shown control foot of the transfer hook 12 by the amount m back.
- the old stitches are then still in the front region of the transfer hook, so that the passage of a new thread for stitch formation after the sector f ( Fig. 16 ) is possible.
- the snap function is to be executed, the controlled path n in the size range of one millimeter is sufficient for the execution of this pattern operation ( Figure 15 ).
- the Fig. 16 shows the greatly enlarged section principle representation in a plan view of the Sch.bahn s.
- the catch function runs in the direction of the arrow when the control feet pass.
- an area is provided before the return stroke of the needle, in which, for example, electronically controlled according to a design pattern, the required return pulses on certain needles Fangmaschen arise. If no Fangmasche arise, the flow remains in the Fig. 10 shown position.
- the coupled retraction of both mesh-forming elements takes place from the in Fig. 10 shown position in the Figure 13 shown position, with electronically controlled needle selection first for all needles of the in Fig. 10 shown position in the Figure 14 shown position and then pulse controlled individual needles of the in Fig. 14 shown position in the Figure 15 shown position.
- Fig. 17 to 20 the process steps for the transfer of stitches in flat knitting machines are explained.
- the stitch formation according to the invention can likewise be advantageously used for flat knitting.
- There are - analogous to the cylinder and the dial of the circular knitting machines - two straight long needle beds, each with a needle 1 and a transfer hook 12 at an angle of 100 degrees inclined, so that in the gaps each a needle of the other bed intersect.
- the needles 1 For longitudinal bed offset the needles 1 must be withdrawn.
- the last formed stitches are suspended on the transfer hook 12.
- the needle channels of both beds are exactly opposite each other during the transfer process.
- Fig. 17 is the right transfer hooks 12 with its slats moved forward so far that the loop to be transferred hanging approximately in the middle of the free opening between the two needle beds.
- the needle beds for the knitting operation have been brought into their basic position "needles to gaps".
- a new thread is inserted in the left needle hook 2 and is then pulled upon withdrawal of the left needle 1 by the stitches held by the left transfer hook 12.
- the Fig. 21 to 23 show a peculiarity of the needle hook 2.
- the lateral displacement of the needle beds over several needle pitches creates a considerable traction in the transverse direction of the stitches, so that the receiving needle can bump with its head on thread sections, instead of hitting the mesh opening.
- a shoehorn-like approach 21 on the needle hook 2 finds just below the transfer hook 12 sure the mesh at this point and the needle head 2 prepares for the transfer process the way.
- an additional diameter reduction 22 is provided on the still unbent front part of the needle hook 2, so that it has flat shape after the subsequent pressing in the transverse direction of the needle 1 half the hook thickness.
- Fig. 22 shows the pressed reduction 22, which is pressed in the transverse direction of the needle 1 to the width of the needle hook 2 in alignment with the later bent inner course of the hook 2, so that after the hook bending corresponds to the 180 degrees bent back front part of the hook thickness and in Fig. 23 shown hook design arises.
- Fig. 24 shows the top view of the back of the slats in the region of the needle slot and the subsequent extension to the channel width in the recess 9 (FIG. FIGS. 5 and 9 ).
- FIGS. 25 to 29 are exemplary embodiments of the stitch forming elements according to the invention for warp knitting machines. These are there in rows in the rear shaft area - clamped in so-called bars - over whose front edge they protrude in the desired fineness corresponding pitches.
- the problem with this is that the free shaft parts of both ingots have to be exactly aligned with each other over their considerable length.
- Various influences, but especially the thermal expansion in the machine play an important role. It is therefore necessary to bring the interacting elements into each other at the important points, as for example with the in the Needle slot engaging tongue-like approach has been proposed.
- a small guide bracket 24 encompassing the shaft is a friction-favorable alternative because the two shaft designs have the same thickness.
- This can be analogous to the tongue attachment in knitting needles eg attach to the shaft 11 of the transfer hook 12 in which two in alignment with the mounting hole 25 against each other acting punch journal stubs press as in the known tongue bearing from the side panels in the mounting hole 25.
- the Fig. 26 illustrates the attachment in a section a - a der Fig. 25 ,
- the Fig. 25 is a schematic representation of the arrangement of both mesh forming elements in separate needle bar. These are pivotally mounted about transverse to the needle elements arranged at a greater distance axes of rotation, so that the elements on a circular path in the longitudinal direction corresponding to Figure 10 move to13.
- the needles 1 are individually stretched in channels of the needle bar, not shown, while the complementary slide parts, cast in sets of the same division in the holding assembly 23, are housed in the second, also not shown ingots together.
- the protruding from the holding assembly 23 shaft is formed in its continuation as a spring 26 which is slightly biased so that in this relative position of the two bars to each other the transfer hook 12 in the needle breast 4 Fig. 25 ), while in the other positions of the transfer hook 12 by sliding the elevation 16 on the rising surface 7 on the upper edge 3 of the needle 1 retains its outward position.
- a control rail 27 is provided over the entire bar length, which engages in the groove 11 corresponding to the transfer hook 12 in the groove.
- the coupling of both knitting elements takes place, as in 10 and 11 represented by means of the projection 14 on the transfer hook 12, which engages in a groove 15 on the end face of the recess 9.
- FIGS. 30 and 31 are schematic representations of the arrangement of the control rail 27. It can be dispensed with the previously heavy swinging construction for the attachment of the bars. It is sufficient to run in a lightweight design vibration system with low mass movements.
- the control rail 27 can be divided into sections that can be easily removed to replace the transfer hook parts.
- a guide beam 30 arranged parallel to the entire billet length of the needles contains guide elements, for example at suitable section distances, e.g. Linear Bushings 31.
- U-shaped oscillating elements as rail supports 32 which have a fastening platform 34 for the control rail 27 at the top and are configured below for the vibration drive, can be moved up and down with the bolts 33 fastened therein.
- the oscillating elements 32 are laterally connected to an axle 35, which can be used for the vibration drive. Also in section distances are mounted on the guide support 30 side bearing plates 38 for the vibration drive.

Neben den Vorteilen, die sich aus der Lösung der Aufgabe ergeben, ist die Erfindung grundsätzlich für alle genannten Maschinenvarianten vorteilhaft einsetzbar. Sie bietet auch für feinste Teilungen mit dem Ziel fester Maschenstoffe vielseitige Musterungsmöglichkeiten.In addition to the advantages arising from the solution of the problem, the invention is basically used advantageously for all mentioned machine variants. It offers versatile patterning options even for the finest pitches with the goal of strong knit fabrics.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are specified in the subclaims.
Mit der erfindungsgemäßen Maschenbildungsanordnung kann eine Strick- oder Kettenwirkmaschine zum maschinellen Maschenbilden mit mindestens einem kontinuierlichen Faden geschaffen werden, der mittels des Hakenteils einer Strick- oder Wirknadel jeweils durch die zuvor gebildete Masche zum Bilden der neuen Masche als Schleife hindurch bewegt wird, wobei die Auswärts-Querbewegung des Transferhakens und die Bewegung der Nadel durch an deren Schaftende angeordnete und in Schlossbahnen eingreifende Steuerfüße während der zueinander relativen Längsbewegung beider Maschenbildungselemente bewirkt wird. Die Maschenbildungselemente werden durch die Kupplungselemente kraftschlüssig verbunden, durch die die Einwärts-Querbewegung des nach oben gerichteten Transferhakens innerhalb des Nadelkanals bzw. (bei Kettenwirkmaschinen) unterhalb des Abschlagkammes während der Vorwärtsbewegung derart steuerbar ist, dass nach Verlassen nach der Kulierstellung der Nadel und Freigabe der alten Masche vom Transferhaken die Maschenbildungselemente gemeinsam in ihre obere Position vorbewegbar sind, derart, dass der Steuerfuß des Transferhakens über einen Synchronanstieg im Maschinenschloss den Kupplungsstoß der Nadel abfängt.With the stitch forming arrangement of the present invention, a knitting or warp knitting machine can be provided with at least one continuous thread which is looped through the previously formed loop to form the new loop stitch by means of the hook portion of a knitting needle Transverse movement of the transfer hook and the movement of the needle is arranged by arranged at the shaft end and engaging in cam tracks control feet during mutually relative longitudinal movement of the two stitch forming elements is effected. The knitting elements are non-positively connected by the coupling elements, by the inward-transverse movement of the upward transfer hook within the needle channel or (in warp knitting machines) below the Abschlagkammes during the forward movement is controlled such that after leaving the Kulierstellung the needle and release the old stitch from the transfer hook the stitch forming elements are jointly advanced in their upper position, such that the control foot of the Transfer hook over a synchronous increase in the machine lock intercept the coupling impact of the needle.
Die Weiterbildung nach Anspruch 2 erleichtert den Maschenübergang von der Nadelbrust zur Haltesektion des Transferhakens für feinste Nadelausführungen und das gesteuerte Herausheben des Transferhakens aus dem Nadelschlitz mit einer selbstreinigenden Schrägbewegung.The development according to
Bei einer mit der erfindungsgemäßen Maschenbildungsanordnung versehenen Maschine sind für die Musterungsfunktion "Fang" vor dem allgemeinen Rückhub der Nadel mit eingeführtem neuen Faden die durch die Musterung festgelegten Steuerfüße des Transferhakens mit einem mechanisch oder elektronisch betätigten Rückwärtsimpuls steuerbar, derart, dass durch Kupplung der Maschenbildungselemente der Nadelhaken und Transferhaken den erforderlichen kleinen Rückhub gemeinsam ausführen.In a machine provided with the stitch forming arrangement according to the invention, for the patterning function "catching" prior to the general return stroke of the new thread inserted needle, the control feet of the transfer hook defined by the patterning are controllable with a mechanically or electronically operated backward pulse such that by coupling the stitch forming elements Needle hook and transfer hooks perform the required small return stroke together.
Die alte Masche kann vom Transferhaken zum im Nadelhaken eingeführten neuen Faden gelangen, bevor die Nadel ihren weiteren Rückhub, gelöst von der Kupplung mit dem Transferhaken, ausführt. Der Vorteil besteht vor allem darin, dass die Kuliernadel immer denselben Bewegungsablauf macht.The old stitch can pass from the transfer hook to the new thread inserted in the needle hook before the needle makes its further return stroke, released from the coupling with the transfer hook. The advantage is mainly that the styling needle always makes the same movement.
Nach erfolgter Kupplung der Maschenbildungselemente sind diese durch den Steuerfuß der Nadel phasenbegrenzt gemeinsam vorbewegbar. Durch den Steuerfuß des Transferhakenschafts sind sie phasenbegrenzt gemeinsam (für Fang) rückbewegbar. Die Kupplung beider Maschenbildungselemente ist durch die unabhängige Rückwärtsbewegung der Nadel lösbar und für die Einwärtsbewegung des Transferhakens kann eine am Nadelschloss angeordnete Gleitkufe vorgesehen sein.After the coupling of the stitch-forming elements, these are together by means of the control foot of the needle phase-limited vorbewegbar. Through the control foot of the Transferhakenschaft they are phase-limited together (for Fang) rückbewegbar. The coupling of both knitting elements is releasable by the independent backward movement of the needle and for the inward movement of the transfer hook can be provided on the needle lock arranged skid.
Die Steuerung der Maschenbildungselemente für verschiedene Musterungseffekte und die Querbewegung des Transferhakens können so verbessert werden.The control of the knitting elements for various Pattern effects and the cross motion of the transfer hook can thus be improved.
Die Maschenbildungsanordnung kann an einer Flachstrickmaschine mit zwei geradlinig langen, abgewinkelt gegenüber stehenden und in Längsrichtung versetzbaren Nadelbetten verwendet werden, die bei der Maschenumhängung mit ihren Kanälen fluchten. Die Transferhakenteile können aus zwei parallelen Lamellen bestehen. Für den Übertragungsvorgang auf die andere Bettenseite kann ein Transferhaken bis zur Mitte der freien Öffnung beider Nadelbetten vorbewegt werden und anschließend kann die Nadel mit dem Haken des anderen Bettes die übergebende Masche und deren haltende Lamellen durchstoßen und aufweiten, so dass sich nach dem Rückzug der übergebenden Transferhakenlamellen alle Maschen sich auf den übernehmenden Nadeln befinden.The stitching assembly may be used on a flat knitting machine having two straight long angled and longitudinally displaceable needle beds which are aligned with their channels during the stitching. The transfer hook parts can consist of two parallel lamellae. For the transfer process to the other side of the bed a transfer hook can be moved to the middle of the free opening of both needle beds and then the needle with the hook of the other bed, the transferring stitch and their holding lamellas pierced and expand, so that after the withdrawal of the transferring Transfer hook blades all stitches are on the receiving needles.
Dadurch wird das Umhängen von den Maschen bei Flachstrickmaschinen ohne komplizierte Änderungen an den Maschenbildungselementen ermöglicht.This allows the knitting of the loops in flat knitting machines without complicated changes to the knitting elements.
Die Maschenbildungselemente können in zwei unabhängig gesteuerten Barren einer Kettenwirkmaschine aufgenommen sein und die Transferhakenteile können einen geringfügig vorgespannten Federbereich aufweisen, so dass über die Relativbewegung beider Barren zueinander die erforderliche Querbewegung des Transferhakens durch Gleitkontakt der Maschenbildungselemente erfolgt. Beide Maschenbildungselemente können auch in einem Barren aufgenommen und die Transferhakenteile darin spannungsfrei längsverschiebbar sein, wobei die Relativbewegung der Transferhakenteile zu den Nadeln über eine Steuerschiene und die Querbewegung des Transferhakens bzw. die Kupplung beider Elemente durch Führungsvertiefungen und zugeordnete fingerartige Vorsprünge am Schaft erfolgt.The stitch forming elements can be accommodated in two independently controlled bars of a warp knitting machine and the transfer hook parts can have a slightly prestressed spring area, so that the relative transverse movement of the two bars results in the required transverse movement of the transfer hook due to sliding contact of the loop forming elements. Both knitting elements can also be accommodated in a bar and the transfer hook parts can be longitudinally displaced without tension, wherein the relative movement of the transfer hook parts to the needles via a control rail and the transverse movement of the transfer hook or the coupling of both elements by guide recesses and associated finger-like projections on the shaft.
Dadurch wird die Anwendung in einer Kettenwirkmaschine mit zwei unabhängig voneinander gesteuerten bzw. nur einem Barren ermöglicht.This allows the application in a warp knitting machine with two independently controlled or only one ingot.
Die Schwingbewegung der Transferhaken und/oder der Nadeln kann jeweils durch in Sektionen unterteilte Schwingsysteme erfolgen, die über Radialnocken, Axialnocken oder über Schwinghebel erzeugt und von einer Steuerschiene auf den Transferhaken übertragen wird.The oscillating movement of the transfer hooks and / or the needles can be effected in each case by subdivided into sections oscillating systems, which is generated via radial cam, axial cam or rocker arm and transmitted from a control rail on the transfer hook.
Dadurch wird die Schwingenkonstruktion für die Befestigung der Barren vereinfacht und das Auswechseln der Transferhakenteile erleichtert.This simplifies the swing construction for the attachment of the ingots and facilitates the replacement of the transfer hook parts.

Unterhalb der Anstiegsfläche 7 im Nadelschaft 3 befindet sich eine Aussparung 8. Bei Relativbewegungen von Nadel 1 und Transferhaken 12 zu einander werden diese beiden Elemente (1 und 12) um den Betrag x von einander wegbewegt. Z zeigt die vertikale Bewegungstoleranz der Elemente (Nadel 1 und Transferhaken 12), in welcher die Einwärtsstellung des Transferhakens 12 in der Nadelbrust 4 sichergestellt ist.Below the rising

Die Maschenbildung erfolgt also statt wie bei den Vorläuferausführungen in vier, jetzt in drei Verfahrensschritten der beiden Elemente. Auf die Rückwärtsbewegung der Nadel 1 mit eingeführtem neuen Faden erfolgt der Rückhub des Transferhakens 12, welcher die von ihm gehaltene Masche freigibt. Die dritte Phase enthält die Aufwärtsbewegungsschritte der Nadel 1 und des Transferhakens 12, d. h. während der Vorbewegung der Nadel 1 erfolgt eine Kupplung mit dem Transferhakenschaft 11 innerhalb des Nadelkanals und anschließend der gemeinsame Vorschub in die obere Position. Die Kupplung innerhalb des Nadelkanals hat den wichtigen Vorteil der Sicherheit beim Eintauchen des Transferhakens 12 in die Nadelbrust 4 und ermöglicht den Toleranzausgleich der in den Nadelkanälen vorhandenen Abweichungen.The stitch formation thus takes place, as in the precursor embodiments, in four, now in three process steps of the two elements. On the backward movement of the
Die vorteilhafte kleine Querbewegung des Transferhakens 12 erfolgt ohne Steuerelement im Nadelschloß allein durch die gegenseitig relative Längsbewegung der beiden Schaftteile. Diese sind einfach strukturierte Bauteile in gleicher Schaftstärke ohne Absetzungen und Überschneidungen. Die erforderliche Genauigkeit läßt sich mit heutiger Stanztechnik gewährleisten, da keine Biegeoperation vorgesehen ist. Typische Nadelfertigungsarbeitsgänge sind nur noch im vorderen Teil des Kulierhakens und der anschließenden Zasche notwendig. Die Erfindung ermöglicht einen kleinen Brustanstieg, d.h. kleine Maschen und größere Freiheit in der Gestaltung von Nadelhaken 2 zur Brusthöhe.The advantageous small transverse movement of the

Beim Kupplungsvorgang ist es bei den hohen Geschwindigkeiten wichtig, die ankommende Nadelbewegung mit einer kurz davor beginnenden Transferhakenbewegung zu harmonisieren.When coupling, it is important at high speeds to harmonize the incoming needle movement with a transfer hook movement just beginning.

Wenn der Transferhaken 12 beim Rückhub der Nadel 1 aus dem Brustbereich auf die jeweilige Hakenhöhe herausgehoben wird, eröffnet sich zusätzlich ein problemloser Übergang von der in die Brust eingetauchten Einführungssektion des Transferhakens 12 zu Haltesektion, ohne die bisher kleine Maschenerweiterung in Kauf nehmen zu müssen. Außerdem, das ist ein weiterer Vorteil, sind hier die Anstiegsflächen leicht herstellbar. Es ist nur noch ein kurzer offener Schlitz in der Nadel notwendig, welcher in eine kleine Vertiefung hinter der Brust mündet. Darin befindet sich die Haltesektion des Transferhakens 12, wenn seine Einführungssektion in die Nadelbrust 4 eingeschwenkt ist. Die Einwärtsbewegung des Transferhakens 12 geschieht innerhalb der seitlichen Führung des Nadelkanals, während der Toleranz-ausgleich in Querrichtung durch den Kupplungsvorgang beim Vorbewegen der Nadel 1 gewährleistet ist.When the

Für die Verwirklichung von Fangmaschenmusterungen hat die Erfindung weitere Vorteile. Im Gegensatz zur jetzt gebräuchlichen Technologie macht hier die Kuliernadel immer denselben Bewegungsablauf. Soll eine Fangmasche entstehen, erfolgt nach dem Einführen des neuen Fadens und vor der Rückwärtsbewegung der Kuliernadel ein kleiner Rückimpuls auf den Steuerfuß des Transferhakens 12, wodurch beide Elemente kraftschlüssig um die Transferhakenlänge nach hinten geführt werden. Die vorherige Masche gelangt dadurch vom Transferhaken 12 wieder in den Nadelhals zum neu eingeführten Faden, der anschließend kuliert wird.For the realization of Fangmaschenmusterungen the invention has further advantages. In contrast to the now common technology makes the styling needle always the same movement. If a tuck stitch occurs, after insertion of the new thread and before the backward movement of the styling needle, a small return pulse is applied to the control foot of the
Die Erfindung ermöglicht auch, frei programmierbar einzelne Nadeln anzusteuern. Dazu kommen Betätigungsmagnete mit extrem kurzer. Ansprechzeit zur Anwendung, weil der Zeitzyklus innerhalb einer Nadelteilung bei den hohen Geschwindigkeiten minimal ist, so daß sehr kurze Steuerungsbewegungen Voraussetzung sind.The invention also makes it possible to control individual needles in a freely programmable manner. In addition, actuation magnets come with extremely short. Response time to the application, because the time cycle within a needle pitch at the high speeds is minimal, so that very short control movements are a prerequisite.

Bei dieser Technologie sind durch Versatz der Nadelbetten in Längsrichtung und anschließendem Umhängen von Maschen auf die andere Bettenseite, vielseitig verschiedene Musterungseffekte erzielbar. Das Umhängen selbst ist ein komplexer Vorgang, der komplizierte Zungennadeln mit seitlichen Aussparungen und Federelementen erfordert, die von den zu übernehmenden Nadeln durchstoßen werden, so daß beim anschließenden Rückzug der abgebenden Nadel die Masche auf die andere Bettenseite übertragen wird. Im Gegensatz dazu läßt sich die Umhängung jetzt grundsätzlich ohne Änderung der zum Stricken verwendeten Nadeln 1 durchführen, wenn der Transferhaken 12, wie bei einer bekannten Vorrichtung dieser Art (

Bei sehr feinen Nadelausführungen ist ein den Schaft umgreifender kleiner Führungsbügel 24 eine reibungsgünstige Alternative, weil die beiden Schaftausführungen dieselbe Stärke aufweisen.
