Description

Technical area

The present invention relates to a needle for knitting a knitting or warp knitting machine, a knitting or warp knitting machine having a plurality of such needles, and a method of manufacturing such a needle.

State of the art

The invention is a further development of the German patent no. 10 2007 039 973 of 23.08.2007, which realizes an advantageous control of the opening and closing movement of a longitudinally guided tongue member without the need for slide needles second castle track. The patent was intended to avoid the disadvantages of the latch needle with ever-finer needle pitches, ie a needle technology without pivoting tongues should be pointed out.

Mechanical pulp production, in contrast to the loom process created thousands of years ago, which made possible components made of wood, is based on new materials created in the technical age for precisely controllable knitting elements, which are used to develop the last stitches created. These elements mentioned elements could only be made of metal, so that their development can be seen as state of the art in metalworking. In 1589, for the first time, hook needles, also called spikes or knitting needles, were created, the reed pin in 1856 and the needle at the beginning of the 20th century.

In particular, it was the latch needle, which prevailed dominant for the mass production of knitted fabrics. The prerequisite for this was hardenable steel, which could only be produced in the required quality from the middle of the 19th century. With this technology, it is an advantage that the thread in stitch formation inevitably takes over a control task by the movement of the tongue and thereby-apart from patterning effects-only one control foot must be provided on the needle. In addition, the pivoting-tongue needle is designed as a ready-to-install functional unit that can be easily inserted and replaced by the operator in the machine. With increasing increases in rotational speeds in circular knitting machines and simultaneous multiplication of the knitting systems, however, the described advantage proves to be a weak point for production safety. Therefore, intensive considerations have been made to find new ways to eliminate the storage-related disadvantages of the pivoting tongue. In this case, found as an alternative to the reed needle technology two-piece knitting elements in which the thread by means of the hook part of a knitting needle or knitting each held by the held on the tip of the complementary element loop as a loop and forms a new stitch, the old stitch over the head the needle is dropped. Thus, for special applications, for example, in warp knitting machines with the extremely short cycle times, this type of needle could already prevail. The disadvantage of this technology in knitting machines, however, is that for each element a special control cam is necessary for its control foot, which must be accommodated in each case in the lock systems. For the double-surface application with the cramped lock constructions there is an additional problem.

From the publication DE 2241 769A Two-part knitting elements are known, which both the phased holding of the slide by a retaining cam and the Stop by braking effect in the needle channel. For the implementation but a considerable length of the slide member is necessary to accommodate the stops for the relative movement of the slider to the needle. The handling in practice for inserting the slider in the machine requires a manageable length of this component. The two-part solution was too complicated for general use and therefore could not prevail over several decades against the latch needle.

The in the published patent application DE 2245 731A Although described embodiment comes without retaining cam on the slide part, which was already anticipated by the former publication. However, this solution is out of the question due to the disadvantages caused by the heating due to the braking action of the slide for high performance machines.

The common technology of stitch formation with latch needles builds on a development period of more than one hundred years with a multitude of different machine types. In order to take advantage of the pivotless loop-forming elements for the various applications with high-performance machines, not so much development time with correspondingly large design effort as previously available. This increases the pressure on innovative new developments.

In order to use in knitting machines, the advantages of the reed needles technology as a functional unit with the advantages of the needles and at the same time to avoid the disadvantage of having to use an extra controlled complementary element in user-friendly size in the machine, is in the DE 10 2007 039 973 .A vibrating-needle technology is provided in which the long shaft of the slider element is transformed into a mini-board member reciprocating within the needle. This is moved in phases along with the needle and on the other hand by the Machine controlled phased stopped. From the point of view of implementation, the longitudinal guide is always more complex than the fulcrum bearing of a component. With usual design models, this would be here as well: the board should have a leadership approach and be secured with tongue and groove laterally against falling out of the needle shaft smoothly, which limits the fineness of execution in addition to these difficulties in mass production. The smaller the board should be, the more complex is a solution suitable for mass production. However, it would be desirable because of the approximation of the movement from the holding state to the movement phase, an approximately massless execution of the longitudinal tongue element. The problematic longitudinal storage with the smallest size is simplified in that between the vibrating member and the needle body, a central connecting bracket is provided which ensures both the relative movement of the oscillating member to Nadelköper and its lateral guidance and on the sliding surface in the needle. In this way, analogous to the up and zuschwenkenden tongue in the needle reciprocating mini-board member realized with the important difference, not by the thread, but to be controlled by the machine.

The central component known from the mechanical watch industry inspired the elevator spring to form a mini-link between the needle body and the thread transfer element. There were unusual needle designs, which reduced the longitudinally movable tongue member to a size comparatively with the pivoting tongue and solved the previous problems of linear guidance of the vibrating member. Thus, as an important prerequisite for the enforcement of this technology in practice, embodiments of functional units that can be produced with less specialized manufacturing processes.

In a design after o.a. Patent is avoided for the leadership of the transmission element, especially in fine versions, the otherwise required high technology. This means as an advantage a hassle-free mounting option of the transfer element to the functional unit, which is possible without loss of quality in manually operated operations. However, the flat structured transfer member requires lateral settlements, which require a not very simple additional operation in the mini components, as is true even with the guide grooves on the needle shank. In another type, which is an interesting alternative for very fine needle sizes, the components are somewhat more complicated and the assembly to the functional unit is only possible by hand, which requires skill.

In both types, the phased arrest of the transfer member during the stitch formation is done by a holding balcony of the issued patent within the needle lock on a stop tooth of the transfer member acts. However, the application of both types would be possible on a much broader basis if no additional elements were required within the lock systems. The machine designs would then be possible on those of the previous latch needle. This would also allow the implementation of the process for double-sided knits. The inwardly tapered knitting systems for the dial exclude other components. In addition, has proven to be a disadvantage that lint particles can penetrate into the gaps of the components that do not remove themselves, but can settle in it and continue to build. The points of view pointed out the basic ideas on which the current invention is based. They have significant implications for the realization in new machine designs and advantages for the manufacture of the knitting elements called needles.

Summary of the invention

The object of the invention characterized in claim 1 is to provide a needle for stitching on a knitting or warp knitting machine, which has a simple, stable and compact construction and can be produced in a simple manner. Moreover, the invention provides a knitting or warp knitting machine with a plurality of such needles according to claim 11 and a method of manufacturing such a needle according to claim 17. Preferred embodiments of the invention follow from the dependent claims.

The needle for knitting on a knitting or warp knitting machine according to the invention comprises a base body, a needle hook and a transmission member or tongue member which is movable in the longitudinal direction of the base body relative to the base body and the needle hook and is adapted to the needle hook by a relative movement to the base body to close and open. The needle further comprises a connector which engages around the transmission member or tongue member along at least a portion of the length of the transmission member or tongue member such that the relative movement of the transmission member or tongue member is guided to the body by the connector, the connector engaging with an upper portion of the body Basic body is connected.

The connecting element may be a U-shaped connecting element. The transmission member or tongue member may be received in the recess of the U-shaped connecting element. In this case, the U-shape of the connecting element engages around the transmission member. In particular, the connecting element may be formed as a U-shaped bracket.

The needle according to the invention makes it possible to effect the control function for the opening and closing movement of a transmission member outside the needle movement system. Another advantage is to be able to influence the positioning of a plating thread in the needle hook. The structure of the functional unit needle with longitudinally guided transmission member is compact, so that no dirt particles can penetrate within the system. Since the connecting member is provided so as to be connected to an upper portion of the main body, the needle can be easily manufactured. Moreover, the needle has a simple and stable construction.

The longitudinal movement of the transfer member or tongue member in the needle may occur during needle movement by phase-limited stopping on an engagement member, such as a cut or bump, of the transfer member or tongue member outside the knitting systems by means of holding blades, for example, lined up around a needle cylinder.

This results in some embodiments, the front of a transfer finger of the transfer member or tongue member on the needle hook by means of a notched projection on its front section. The transfer finger height is advantageously larger and more stable due to a reduction, and its underside can also be formed for the exact positioning of a plating thread. This is an important advantage of one aspect of the invention because plating forms the basis for a large number of pattern types. In this case, two different threads must be supplied separately to the needles and cover a cover thread as the basic thread. This requires a precise positioning of the threads in the needle, which must be preserved in the stitch formation. In trials of various users with the known needles has Surprisingly, it turns out that safety is less here than with tongue needles. The result was that this type of needle could not prevail in knitting machines. This shows what imponderables are to be expected when entering the thread and how unmanageable small differences play a decisive role. It can only be presumed that the tongue shaft widened for storage is a feature of importance.

The design possibility of the widened transfer finger favors the fulfillment of the high demand uniform positioning of the separately supplied threads in the needle hook.

The connection of the invention of the connecting element with the upper portion of the body allows easily replaceable needle elements, which types of knitting arise that extends the scope for double-surface generating circular knitting machines to flat knitting machines in designs from coarse to fine.

The transfer member or tongue member of the needle becomes the rod-shaped profile of a compact design which together with the main body or needle body forms a prismatic body without interruptions or recesses which completely fills the needle channel and thereby prevents the ingress and seizing of dirt particles. The stop tooth on the tongue member within the knitting system and the corresponding holding balconies can be replaced by measures outside the knitting systems. Instead of the stop tooth, at the top, in particular at the top, a narrow holding recess or alternatively a bump may be provided in a shank of the transfer member or tongue member, in which during the downward movement of the needle to close the needle hook an engaging unit of the knitting or warp knitting machine, such as the projection one Blade section outside the castle, engages. These blade sections can be supplemented at the top of the lock to form a ring around the needle cylinder. These are simple platinum parts that line up in a stop recess on the upper side of the lock and can be fixed there using familiar technology, including gluing. To close the needle hook, for example, a second section projection can be used, which stops the transmission finger on the transmission member or tongue member in the needle-down movement. The arrangement allows the simplest realization of the desired relative movement of the transmission member or tongue member to the needle body without additional controls. In this way, completely new machine conceptions can be made possible. The transmission member or tongue member becomes easy to manufacture component and can then placed both with device handling and automatable placed over the needle body, above, in particular perpendicular, the connecting element, such as a particular U-shaped connecting bracket inserted and, for example, beyond the tongue member base protruding leg be fastened in fixing recesses on the needle shaft. The stitch-forming function corresponds to that described in the starting patent.

The fact that inside the lock systems no holding balconies must be provided, the application of the transfer element or tongue member technology is possible on a broader basis. In particular, in RR machines, where the rib locks taper backwards, the clear control outside the lock is important.

The invention is basically applicable to all machine variants and is particularly advantageous for the finest pitches and lowest mesh heights with the aim of solid mesh fabrics.

In some embodiments of the present invention, the main body has the upper portion immediately adjacent to the needle hook in the longitudinal direction of the main body, a central portion immediately adjacent to the upper portion in the longitudinal direction of the main body, and a needle foot extending longitudinally of the main body to the middle section adjoins. The needle foot can connect directly to the middle section in the longitudinal direction of the main body.

The gap may lie in a plane or extend in a plane which is parallel to the plane in which the needle curvature of the needle hook extends.

The transfer member may have at an upper end thereof in the direction of the needle butt on the needle hook to a transfer finger, which is adapted to close and open the needle hook by the relative movement of the transfer member to the base body.

The transmission finger may have an upper portion and a lower portion which adjoins the upper portion directly in the longitudinal direction of the main body.

The upper portion of the transfer finger may have a smaller lateral extent perpendicular to the longitudinal direction of the main body than the lower portion of the transfer finger, so that a step is formed between the upper portion and the lower portion.

The needle may be arranged so that the step of the transfer finger forms a stop surface for a lower end surface of the needle hook, so that the relative movement of the transfer member to the main body upwards, ie in the direction of the needle hook, is limited by the step.

In contrast, the execution of the FIGS. 18 to 20 a clear design of a single knitting machine without blanks. Instead of this, the turns of a spring-ring spiral engage with a pitch corresponding to the pitch above the knock-off edge of the needle cylinder from the back of the needle into the intermediate spaces of the needles. Instead of the sinker ring, the smooth bearing point (ball bearing) for receiving horizontal guide segments for fixing the spring ring spiral is provided on a downwardly extending journal, which in Outer diameter is so large that the turns engage in the interstices of the needles and so hold down the stitches in the needle upward movement.

Fig. 1 shows in a side view and plan view of the needle body or base body 1, which has the needle-specific features needle hook 2, needle face 3, needle slot 4. Behind this is the offset 5, which is up to the end stop 6 for the transmission member 11 (FIG. Fig.2 ) in its rear position extends. The needle hook 2 includes a zipper at the top for receiving the transfer finger 12. Lateral fixing recesses 7 are for mounting and fixing a connecting bracket 8 (FIG. Figure 3 ) is provided with its attachment zone of the open legs 9.

The Fig. 2 is also a side view of the transfer member 11, which forms a prismatic body as a flat component without depositions to the end face 15 which completely fills together with the needle body 1 within the needle channel and merges with the transfer 12 at the front of the transfer finger 12a. In the vicinity of the end face 15 of the retaining recess 13 is provided.

In addition, shows Fig. 3 schematically a welding point through which the connecting bracket 8 is connected to the upper portion of the main body or needle body 1.

In the Fig. 4 is shown in a side view of the fully assembled compact functional unit Längszungennadel. The transfer member 11 is thereby in the front closed position of the needle hook 2 by the transfer finger 12 due to the abutment of the offset 12a at the front edge of the needle hook 2. In this position Penetrating thread particles at the rear end of the transmission member 11 can not build up. They are pushed at the opening of the needle hook to the stop 6, where they pass through its bevel again from the needle channel.

The Fig. 5 shows the front part of the Fig. 4 in 20x magnification. At this time, the transfer finger 12 widened around the step 12a supports on its lower side the separate positioning of the plating yarn from the main yarn for the knitting operation of the plating. For this purpose, the bottom may have a Leitkufe L, which directs the Plattierfaden to the bottom in the hook 2 and the transfer finger 12 leads exactly to the hook center.

Fig. 6 is the schematic representation of the thread inlet during the plating process in 4 phases. Plating or covering forms the basis for a large number of pattern types. In this case, the two different threads must be supplied to the needles exactly separated from two thread guides. In this case, the cover yarn D is fed at a more acute angle relative to the background yarn G and passes during the relative movement of the needle hook 2 to the transfer finger 12 on the underside of which ie closer to the needle shank and to the knock-off edge as the introduced in the needle hook 2 ground yarn G.

The Fig. 7 is the graphically enlarged 3D principle representation for the arrangement of the functional parts for opening and closing movement of the transfer finger 12 with respect to the needle hook 2. The needle cylinder N contains the top 16 in the channel side walls of the piercing 16 before the steel band section 17 and in the cycle of the needle positions the projections 18th , once in the retaining recess 13, the other times on the end face 15 of the transmission member 11 are in operative connection. For better understanding, the channel side walls are hidden. The The direction of rotation of the cylinder is clockwise. The steel belt section 17 is an example of an engagement unit of the knitting or warp knitting machine.

The Fig. 8 is a schematic diagram of the arrangement of a steel band section 17 at the top of the lock system in a stop recess 20. In addition, a steel band cover 25 may be attached unusually glued, so that there is a gap in which the steel band section 17 is held under tension.

• In Fig. 9 befindet sich die Nadel 1 in der Einlaufzone des Stricksystems. Die letzte Masche wird über der Nadelbrust 3 mit dem darin befindlichen Übertragungsfinger 12 (Fig.10) in Austriebsstellung gehalten, d.h. das Übertragungsglied 11 befindet sich in der hinteren Stellung am Anschlag 6 der Nadel 1 und ein neuer Faden wird in den Nadelhaken 2 eingeführt. Der erste Haltevorsprung 18 der Stahlbandsektion 17 befindet sich im Halteeinschnitt 13 des Übertragungsgliedes 11.

FIGS. 9 to 13 show schematic representations of the stitch formation in a section through the needle channel under the action of the fastened on the top of the lock steel band section 17 with the retaining projections 18 in the back and forth movement of the functional unit Längszungengliednadel on the relative movement of the transfer member 11 to the needle 1. Here, with Z is the section through the Needle channel with therein Längszungengliednadel 1 and designated S the section in the upper region of one of the rows of cylinders on the cylinder surface knitting system. As a needle passes through the knitting system, it performs the following functions:

• In Fig. 9 the needle 1 is in the inlet zone of the knitting system. The last stitch is placed over the needle face 3 with the transfer finger 12 (FIG. Figure 10 ) held in Austriebsstellung, ie the transfer member 11 is located in the rear position on the stop 6 of the needle 1 and a new thread is inserted into the needle hook 2. The first retaining projection 18 of the steel belt section 17 is located in the retaining recess 13 of the transmission member eleventh

During the further rotation of the cylinder to Fig. 10 the needle 1 was withdrawn. In this case, the transmission member 11 with its holding notch 13 by sliding along on Holding projection 18 stopped, so that in this phase of the return movement, the last stitch on the transfer finger 12 passes and thereby the new thread is included. The retaining recess 13 is now at the beginning of the first gap on the steel belt section 17th

Fig. 11 shows the state in which by further return movement of the needle 1 of Fig. 10 to Fig. 11 the holding recess 13 was located above the first gap of the steel belt section 17, so that the needle 1 moved together with the forwardmost transfer member 11 in the Kulierstellung. During this process, the old mesh is thrown off the transfer finger 12, so that now a new loop in the needle hook 2 depends. Before the movement reversal of the needle 1 to the front, the second retaining projection 18 of the steel belt section 17 is already above the end face 15 on the transmission member 11th

Fig. 12 shows the state in which by the forward movement of the needle 1 of Fig. 11 to Fig. 12 the transfer member 11 was stopped with its end face 15 from the second retaining projection 18 and the transfer finger 12 the needle hook 2 opened, ie this gets back into the needle breast 3. The face 15 is already at the beginning of the second gap of the steel belt section 17. The new mesh passes from the needle hook 2 to the breast rise 3. The groove 16 in the channel side wall of the needle cylinder is visible.

Fig. 13 shows the final phase, ie the state of Fig. 12 to Fig. 13 , in which no retaining projection 18 of the steel belt section 17 is present, ie needle 1 and transmission member 11 come together in the Austriebsstellung. The retaining recess 13 runs in the next knitting system again in the retaining projection 18 of the steel belt section 17 a.

Between the representations according to FIGS. 12 and 13 There is also the possibility with the same selection technique as with tongue needles, to make Fangmaschen. This is also a particular needle 1 is not like Fig. 9 shows fully, but only expelled so far that the end face 15 is below the steel belt section 17. In the subsequent return movement of the needle 1 together with the transfer member 11, the transfer finger 12 remains in the needle breast 3, so that the mesh located there again enters the needle hook 2, in which a new thread has already been captured.

The FIGS. 14 to 17 illustrate the two different arrangements of the steel belt sections 17 on the lock system, the holding projections 18 project once from the inner surface and the other times are flush with this. This also causes differences in front of the transfer member 11 and the needle cylinder N.

In the Fig. 14 on the left is the retaining projection 18 of the steel strip section 17 in engagement of the holding recess 13 on the transfer member 11 to its stop in the return movement of the needle 1, while in the Fig. 14 on the right, the second retaining projection 18 above the end face 15 stops the transmission member 11 during the forward movement of the needle 1.

The Fig. 15 above shows in a section of the cylinder and the upper lock area the engagement of the lock inner surface protruding holding projections 18 in the recess 16 of the channel webs of the needle cylinder N. The bottom view is the top view of the cutout with a view of the needle channels and the detection of holding projections 18, which protrude into the invisible puncture 16 of the side walls.

In Fig. 16 the transfer member 11 instead of the holding incision 13 on a bump 14, which in the left Fig. Below and in the right Fig. above a Active connection with the holding projections 18 on the steel strip section 17 is received. The retaining projections 18 do not protrude beyond the inner surface of the needle lock. For the space requirement of the hump 14 in the return movement of the needle 1, a recess 19 is provided below the retaining projections 18 in the needle lock.

The Fig. 17 Above shows in a section of the cylinder and the upper lock area corresponding to the needle cylinder outer diameter retaining projections 18 on the recess 19 on the needle lock for the forward and backward movement of the hump 14 on the transfer member 11 and the bottom in plan view, the visible holding projections 18 of the steel belt section 17th

In the Fig. 18 It can be seen how the spring ring spiral 55 is guided in the guide segments 56, on the other hand, are received around a smooth bearing 52 on the bearing pin 53 in a retaining ring 54. Thus, the retaining ring 54 rotates by the engagement of the spring ring spiral 55 in the needle gaps in synchronism with the needle cylinder.

The Fig. 19 is the top view of Fig. 18 into a guide segment 56 for the spring ring spiral 55 with the representation of the engagement of some turns of the spring ring spiral 55 in the needle gaps.

Fig. 20 is a section through the needle cylinder N after the withdrawal of the needle 1, in which the bump 14 closes by engaging the retaining projection 18 of the steel belt section 17, the needle hook, as shown in Fig. 18 is apparent.

The FIGS. 21 to 26 are schematic representations of the stitch formation of a single circular knitting machine using conventional boards and based on the in Fig. 20 shown new machine concept in one Section through the needle channel and the attached circuit board ring.

Fig. 21 shows the position of the board P to the needle 1 at the beginning of the thread inlet. The last stitch is located in the inclusion throat of the board P. Above this, the board P has a guide nose 29 for the thread inlet in the needle hook 2.

In the Fig. 22 has the board P so far moved back during the return movement of the needle 1 that their Leitnase 29 for the thread is still behind the needle hook 2 and the thread passes during inclined sliding past within the needle hook 2, so that this before closing the needle hook. 2 was safely introduced there by the transfer finger 12.

By further withdrawal of the needle 1 according to Fig. 23 The old stitch was brought from the base of the inclusion throat to just before the tee position and the new thread was formed into a loop. The board P was moved back slightly.

The Fig. 24 shows the Kulierstellung the needle 1 with simultaneous ejection of the old stitch from the needle hook 2. In this case, the board P goes back completely, so as not to hinder the formation of the new stitch in the needle hook 2.

In the Fig. 25 the needle 1 has already advanced a bit and the board P assumed its front position, so that after further forward movement of the needle 1 for Fig. 21 located in the needle hook 2 new mesh is retained by the Leitnase 29 of the board P and passes to the needle breast 3.

The Fig. 26 shows on the left the view from the front on the thread guide, like the thread afterwards as a result of the thread feed forms an angle in the Kulierung and right as in the side view of the needle hook 2, by the Leitnase 29 on the board P, the thread is introduced into the interior of the needle hook 2.

The Fig. 27 is a sectional view of the 3D representation of the needle cylinder N with the pressed-on circuit board ring 22 as an assembly unit that allows a new machine design. Below the sinker ring 23 is the recess 16 in the side walls of the needle channels.

The Fig. 28 is in 3D representation the front view of the Fig. 27 , It can be seen how the board slots are arranged between the needle channels. The embodiment of the sinker ring 22 with carbon fiber material may be advantageous.

The Fig. 29 is the 3D representation of an advantageous single-circular knitting machine with individually controlled boards P through the disposed above the sinker ring 23 control cam 27, which can be adjusted radially by means of a control screw 25.

Fig. 30 is the 3D principle representation of a RR circular knitting machine with needle technology according to the invention. In this case, instead of the sinker ring a dial R is provided, in which so-called Rippnadeln are provided on the gap to the cylinder needles. In this way, double-surface knits can be produced. The execution of the transmission member 11 is here after the Fig. 16 shown with hump 14.

FIGS. 31 to 37 For the sake of completeness, the use of features of the invention is also apparent for latch needles. In this case, the larger needle path in the mesh formation in the eye, which affects less systems. Instead of the usual boards, which gives an insight into the stitch formation there are mesh holders / sliders here that make an accessible machine concept possible. The Fig. 31 Fig. 3 is a view of the side surface of a mesh slider 22 which is in its forward position through the forward slide 33 of the previous system. When pushing the needle 1, the retaining lug 24 formed by the limited upward entrainment by means of the loop stitch to the cylinder upper edge a gap Sp, so that the old mesh could slip through. The illustrated Vorwärtsgleitscheibe 33 is still the previous system, that is no longer effectively present, so that upon further rotation the spring steel 31 in action in the recovery section 30 in action until the mesh sliding element 22 in his in the Fig. 32 shown Rückwärtsendstellung passes. At this point, the Federstahlleitband 31 on the upper side surface has a bulge 34 under this effect, the retaining lug 24 is pressed by means of the rocking movement of the shaft bottom on the tee edge A. Thereafter, from about the middle of the system with further cylinder rotation in the segment control attachment 29 no spring steel band housing 32 longer exists and the forward slide 33 now occurs in action, as in the Fig. 33 is shown.

FIGS. 34 and 35 are additional explanations of the type after the FIGS. 31 to 33 for the Segmentsteueraufsatz 29. This contains the housing 32 with Federstahlleitband 31 and the recording of Vorwärtsgleitscheibe 33. The housing 32 is in the Fig. 34 in the central elevation section of the control block 29 shown as a side view. Also, a mesh slider / holder 22 inserted into the slit ring 23 is shown as a side view in FIG Fig. 34 pictured at the rear end in its rear position. In this case, caused when the needle 1 advances the entrainment of the retaining lug 24 caused by the thread loops, bounded by the cover rail 35, the gap Sp to the Abschlagkante A ( Fig. 31 ). The Federstahlleitband 31 is engaged in the Rückholausschnitt 30 of the mesh slider / holder 22, which is due to the upward movement of the retaining lug 24 in the lower tilted position.

Fig. 35 is the top view of the right-handed slot ring 23 in which the rear portion of a mesh slider / holder 22 is inserted in the slide slot 21 in the reverse position and the view of the fixed segment control cap 29 without the cover rail 35, so that in the upper half of the housing 32 and in the lower half of the forward sliding plate 33 is recognisably mounted in the segment control attachment 29. A recess 36 in the housing 32 results in two side bars whose slots 37 correspond to the return path of the mesh slide / holder 22 with distances to the axis of rotation. The illustration also shows that the spring steel guide band 31 protrudes beyond the housing 32 side webs in the region of the forward sliding plate 33 and there the spring steel 31 has a bulge 34, under this effect, the mesh slide / holder 22 presses with its retaining lug 24 on the tee edge A ( Fig. 32 ).

Fig. 36 is the right partial top view of the side surface of the Federstahlleitbandes 31, in the right end of the bulge 34 is recognizable on the upper edge.

Fig. 37 shows how in a recess of the tee A, a spring wire ring 40 is received, which is inserted in a groove on the front side of the cylinder Z, wherein the seat fixation is ensured by phased contact pressure from the retaining lugs 24.

In today's fierce competition, only a few needle manufacturers are left to meet the increasing precision requirements. Intensive preoccupation with constant changes and the stimulation of other technologies have created an exceptionally well-constructed needle concept Realization hardly has any relation to the introduced operations. The basic idea here is a needle that consists of two functional sections, which are combined with laser technology. The result is vaccine needles that can significantly reduce inventory levels in family groups. Connected with this are new ways of making needle, which can also entice newcomers to deal with it, because the mastery of the previous production is not a prerequisite. On a needle body, which can be used as known in the machine, different stitching sections can be seeded. In the course of the long development time of the most diverse mesh applications, various textile machine concepts have arisen, in which the invention can play a central role.

An embodiment of a needle according to this new technology is disclosed in U.S. Pat FIGS. 38 to 43 shown. The FIGS. 44 to 47 and 48 to 50 show two examples of applications of such new needles.

The Fig. 38 is the representation of this overall concept knitting or knitting needle 40 consisting of needle body 41 and mesh section 42, in which the transmission tongue 43 is longitudinally movably contained. The mesh section 42 is an embodiment of the fastener according to the present invention. The flat sides of the U-shaped mesh section 42 go forward in the split needle breast 3 and the two-part needle hook 2 over. The needle body 41 can either be offset on both sides in front, so that the mesh section 42 introduced above is laterally flat, or as shown, are placed on the shaft of the needle body 41 adapted to the interior of the U-shaped mesh section 42. It is then expedient to provide a small U-bracket in the region of the foot in order to stabilize the weaker shaft of the needle body 41 as it moves in the needle channel.

Fig. 39 is the representation of the needle body 41 and the small stabilizing U-bracket for the needle foot for movement in the needle channel of the textile machine, wherein just in the needle body 41, a recess for receiving the transmission tongue 43 is provided.

Fig. 40 is the side view of the U-shaped bracket of the mesh section 42, in which the two-sided course of the flat sides merges forward into the chest and hook halves (polished steel surfaces instead of milled surfaces). The lower edges are welded to the lower edge of the needle body 41 by laser technology. In this case, in particular a laser weld seam can be formed for connection.

Fig. 41 is the side view of the transmission tongue 43, which has just the transmission finger 12 and the shaft below the retaining tooth 45.

Fig. 42 is the view of the development of only flat board of the U-shaped bracket of the mesh section 42 in Fig. 40 with stop breakthrough 44 for the holding tooth 45. From there above and below, a narrow zone of the central axis is soft annealed by laser technology, so that the U-bend to the mesh section 42 can be performed.

The stop breakthrough 44 may be formed so that it the relative movement of the transmission member or the transmission tongue 43 to the base body upwards or forwards, ie in the direction of the needle hook, and / or down or back, ie in the direction of the needle foot , limited. This limitation is achieved by an interaction of the Anschlagdurchbruchs 44 with the holding tooth 45th

Fig. 43 Below shows the view from the front of the split needle head, which was welded in the base area and in the area of the transfer finger 12 a this adapted having a bent bed and Fig. 43 Above shows the view of the split side surfaces of the mesh section 42, which are welded together unifying front and just, not visible, form the receiving bed for the transfer finger 12.

The needle hook thus has two halves, the two halves being separated by a gap.

Intensive reflection on the opportunities and risks of the technology based on lateral thinking was the reason for identifying further advantageous applications that should not disappear in the drawer. The following further embodiments are the result of the supplement.

In flat knitting machines, transferring stitches to other needles is an important way of designing versatile patterns. To solve this problem, complex Umhängenadeln have arisen for the existing technology, in which the accepting needle pierces laterally in a mesh expansion of the donating needle and so the mesh transfer occurs during withdrawal of the donating needle.

In the FIGS. 44 to 47 is the mesh transfer to a needle of the other needle bed of a flat knitting machine, without having to make complicated effort on the needle, can be seen. For this process, the two needle beds are brought to each other in the alignment position of the needle channels and in the Fig. 44 the donor and the accepting needle are shown in the starting position, each with a loop in the needle hook.

In the Fig. 45 has moved on the right side of the donor needle so far that the thread loop located in the hook over the needle breast of the mesh section 42 and thus also slides over the transmission tongue 43. The Flat sides of the mesh section are inflected on their underside to the center, so that in Fig. 46 advancing the inner surfaces of the receiving needle hook halves by advancing over the outer surfaces of the stitching section 42 to engage the overlying loop to be dispensed thereon, which subsequently engage the flat sides of the needle breast of the receiving needle. With the return movement of the donating needle closes her needle hook and on further return movement to the Fig. 47 the stitch to be dispensed reaches the needle breast of the receiving needle.

Figures 48 to 50 show the representation of the stitch forming center of the significant pulp production of a warp knitting machine. In this machine design, the needles are not housed individually movable in needle beds, but firmly clamped in so-called needle bar in a certain division. To stitch, all needles move together. Patterns that are based on the basic functions of knitting, non-knitting and tufting are not possible here. Parallel to the needle bars, the needle closing elements are provided in a second bar system in the machine. This requires many functional parts in a confined space. The use of laser technology based function needle with two-piece hook after the FIGS. 38 to 43 avoids the second ingot. Instead of this occurs over the bar length provided holding rocker 50, which the effect of in FIGS. 16 and 17 shown retaining projection 18 on the bump 14 takes over. Instead of the recesses in the holding projections 18, the pivoting of the holding rocker 50 occurs.

The Fig. 48 shows the needle bar B in the upper position. The recorded in a fixedly connected to the machine bearing rail 51 holding rocker 50 is pivoted and its retaining projection 18 is located under the bump 14 of the transmission tongue 43rd

The holding rocker 50 can be provided continuously over the entire length over which the needles are arranged.

The pivoting movement of the holding rocker 50 is synchronized with the up-and-down movement of the needles.

In Fig. 49 the needle bar B was swung back and thereby closed by stopping the hump 14 on the transfer member 43 of the needle hooks. Thereafter, the holding rocker 50 is swung out, so that in the further downward movement of the bump 14 on the retaining projection 18 is moved past how the Fig. 50 in the lower needle bar position represents.

During the upward movement of the needle bar B, the controlled settling of the holding rocker 50 is an analogous process.

An interesting further development is to carry out the holding rocker in a lamellar manner in order to influence the stitch formation for desired patterns by means of control magnets on individual needles.

All of the needle designs described so far are based on manufacturing technology that has been formed and improved over decades. Few needle manufacturers have survived the tough global competition to meet the increasing demands for precision. The constant accompaniment of the changes and impulses of other technologies has resulted in an exceptionally manufacturable needle concept, which is starting from Figure 38 was presented. This results in new ways of needle production, which can also be used by newcomers.
