Definitions

  • Slider needles for stitch-forming textile machines have been well known to those skilled in the field of textile technology for many years.
  • Stitch-forming textile machines in which slider needles are used are, for example, circular knitting machines, flat knitting machines or warp knitting machines.
  • Slider needles essentially comprise two individual parts, a slider and a needle body, both of which extend predominantly in a longitudinal direction. The slider is arranged so that it can be moved relative to the needle body. At the front end of the needle body there is a hook with an interior hook space that is open at the top. By means of a suitable relative movement of the slider, this interior hook space can be opened and closed depending on the position of the slider relative to the needle body.
  • Slider needles therefore differ from other needles for stitch-forming textile machines mainly in the way in which the interior hook space of their hook is closed.
  • stitches are formed using slider needles. To do this, a yarn is first inserted into the interior hook space and a half stitch is formed by a pulling-in movement of the slider needle. During a subsequent expulsion movement of the slider needle, the slider is then moved relative to the needle body in such a way that the hook interior is opened and the half stitch slides along the shaft of the slider needle out of the hook interior. A yarn is then again inserted into the open hook interior.
  • a half stitch and a stitch differ in the number of their Binding points, where the binding points are those points at which a (half) stitch touches the (half) stitches preceding and/or following it.
  • a half stitch is in contact with only one previous stitch at two points and therefore has two binding points on the stitch feet.
  • a stitch on the other hand, is in contact with a previous and a following (half) stitch at two points each. A stitch therefore has four binding points.
  • the EP131709A1 shows a typical slider needle for stitch-forming textile machines, which has a needle shaft in which a U-shaped groove is formed that opens upwards in the vertical direction.
  • the groove is delimited laterally by two shaft walls and downwards by a groove base.
  • a slider is accommodated in the groove so that it can be moved longitudinally, whereby the slider can slide on the groove base.
  • the groove is at least partially closed by a guide web. It is known that lint and dirt particles can penetrate the groove of a slider needle during knitting operation, which leads to an increased power requirement of the knitting machine and increased wear of the slider needle. In order to ensure that lint is removed, the groove therefore has an additional opening in its base or in one of the shaft cheeks.
  • a compound needle according to the invention comprises a needle body with a needle shaft which extends predominantly in a longitudinal direction.
  • the needle shaft can have a substantially rectangular cross-section with preferably rounded edges.
  • the needle shaft can also have a substantially oval or round cross-section.
  • a hook is connected to the needle shaft, the hook enclosing a hook interior that is open upwards in a height direction perpendicular to the longitudinal direction.
  • the needle shaft comprises a groove, which is an elongated depression in the needle shaft that has an opening directed upwards in the height direction and is delimited downwards in the height direction by a groove base.
  • the groove can have a U-shaped cross-section.
  • the width direction runs perpendicular to the longitudinal direction and perpendicular to the height direction.
  • a slider of the slider needle rests on the groove base and is guided in the groove so that it can be displaced in the longitudinal direction in such a way that it can close and open the hook interior in the height direction with its front end in the longitudinal direction.
  • the slider is supported in the height direction on the groove base. It is often advantageous if the slider only rests or is supported on the groove base in the vertical direction.
  • the slider has a working area that at least partially delimits the slider in the vertical direction upwards and that enables the transport and discarding of a half stitch during knitting.
  • the transport of a half stitch is understood, for example, to mean the sliding of a half stitch along the longitudinal direction of the slider needle.
  • the discarding of a half stitch is understood by the specialist in the field of textile technology to mean the sliding of a half stitch over the closed interior of the hook and off the slider needle so that the half stitch no longer has contact with the slider needle.
  • a discarded half stitch or stitch does not wrap around the slider needle.
  • the working area is the area of the slider that has direct contact with the half stitch during knitting. The working area of the slider therefore includes, among other things, the part of the slider with which the interior of the hook can be closed.
  • the slider is guided in the groove in such a way that a half stitch in knitting operation can exert a force on the working area of the slider, which is directed downwards in the vertical direction and leads to an increase in the pressure force of the slider on the groove base.
  • the force can preferably be exerted by direct contact of the half stitch with the working area of the slider. This guides the slider securely on the groove base and prevents the formation of a gap between the slider and the groove base, into which large amounts of fluff and dirt could penetrate and remain.
  • the force is preferably in the The force can be exerted on the slider in the area of the longitudinal extension of the groove. The direction of action of the force then intersects with the base of the groove.
  • the force can preferably be exerted on the slider when the hook interior is open, when the half stitch slides along the needle shaft during knitting. When the hook interior is open, the slider is displaced as far as possible in the longitudinal direction away from the hook relative to the needle body. A force can also be exerted on the slider in this position with a half stitch.
  • the slider usually has no projections or elevations in the working area that prevent a half stitch from sliding along or that cause a half stitch to widen.
  • the slider usually also has no projections or elevations in the working area that can be used to exert a control force acting in the longitudinal direction on the slider, with which the longitudinal movement of the slider can be controlled.
  • Stitch-forming textile machines usually have a needle channel that is delimited in the width direction by groove walls. The needle body and the slider of the slider needle can advantageously be guided together in the needle channel of a stitch-forming textile machine so that they can be displaced in the longitudinal direction, with the needle body and the slider also being displaceable in the longitudinal direction relative to one another.
  • Slider needles according to the invention can be operated in such a way that a half stitch is formed with a yarn in their hook interior.
  • the yarn is usually inserted into the hook interior for this purpose when it is open.
  • the half stitch formed slides longitudinally away from the hook along the needle shaft out of the hook interior.
  • the slider needle When operating in a stitch-forming textile machine, the slider needle preferably makes an expulsion movement - the hook of the slider needle moves longitudinally out of the needle channel. With the half stitch, which has previously slid out of the hook interior, a force is then exerted on the working area of the slider, which is directed downwards in the vertical direction and increases the pressure force of the slider on the groove base.
  • the slider Due to the increased pressure force, the slider is held particularly firmly on the This means that no gap can form between the slider and the groove base during operation. The entry of lint, dust and dirt into the groove of a stitch-forming textile machine can be reduced particularly effectively in this way. In addition, a particularly uniform stitch pattern is produced.
  • the needle body has two shaft walls which delimit the groove over its entire length in the longitudinal direction in the width direction, which runs perpendicular to the longitudinal direction and perpendicular to the height direction, at least on one side, but preferably on both sides.
  • the shaft walls make it possible to position the slider firmly in the width direction. The slider is therefore not displaceable in the width direction relative to the needle body.
  • the shaft walls are two parallel legs of the U-shape which are connected to one another at their ends by the groove base, with the cutting edge of the groove base running at least partially perpendicular to the cutting edge of the shaft walls.
  • the at least two shaft walls of the slider needle have a recess and the working area of the slider projects beyond the recess in the vertical direction or is flush with the recess in the vertical direction.
  • the working area preferably projects beyond the recess or is flush with it when the slider is in a position in which the hook interior is open.
  • the slider is then in a retracted state.
  • the slider is thereby displaced to the maximum in the longitudinal direction away from the hook relative to the needle body.
  • a particularly large force can be exerted on a slider that projects beyond the recess or is flush with the recess with a half stitch if the half stitch slides along the shaft in the area of the recess.
  • the at least two shaft walls of the slider needle can have at least one elevation.
  • the elevation protrudes above the working area of the slider in the vertical direction.
  • the working area of the slider preferably projects beyond the recess at least when the slider is in a retracted state. If the shaft walls also have a recess, the elevation is arranged in the longitudinal direction between the recess and the hook.
  • the slider needle can have a guide bar that is connected to at least one of the shaft walls and at least partially closes the opening of the groove in the vertical direction. If the shaft walls of the slider needle have a recess, the guide bar advantageously adjoins the recess in the longitudinal direction, pointing away from the hook.
  • the guide bar is preferably an integral part of the needle body. It is particularly advantageous if the guide bar is a part of at least one of the shaft walls that is bent in the width direction.
  • the guide bar increases the stability and in particular the rigidity of the slider needle. Slider needles with such a guide bar are particularly suitable for high-speed stitch-forming textile machines.
  • the half stitches formed with a slider needle are usually widened or stretched when they slide from the hook interior onto the needle shaft.
  • the slider needle can be designed in such a way that the widening is as small as possible.
  • a needle breast which limits the needle body upwards in height and which is connected to the hook, can have a diagonally rising course in the longitudinal direction away from the hook. Due to the diagonally rising course, the stitch is initially continuously stretched as it slides along the needle breast. This prevents the half stitch from stretching too quickly or abruptly.
  • the slider needle can also be designed with a groove. The groove is a depression in the needle back and overlaps with the working area of the slider in the longitudinal direction.
  • the needle back usually is the area of the slider needle that limits the needle body downwards in height.
  • the needle back is designed to rest on the bottom of the needle channel of a stitch-forming textile machine.
  • the groove can be arranged in such a way that it extends lengthwise only in the working area of the slider - i.e. it completely overlaps the working area in the lengthwise direction.
  • the widening of the half-stitch also influences the amount of force that is directed downwards from the half-stitch onto the slider in the vertical direction. It has been shown that by reducing the expansion of the half stitch, the friction between the slider and the needle body can also be reduced. The slider needle then requires less power during operation and enables energy to be saved.
  • Slider needles are usually driven by engaging in a cam part of a stitch-forming textile machine.
  • the cam parts have at least one groove-like depression along a cam curve.
  • Drive feet of the slider needle protrude into these groove-like depressions and are driven to move longitudinally during knitting according to the course of the cam curve.
  • the needle body preferably has a needle drive foot on its rear end of the needle shaft pointing away from the hook, which projects above the surrounding areas of the needle shaft in the vertical direction and is suitable for engaging in the at least one groove-like depression of a cam part.
  • the needle body can also have more than one needle drive foot.
  • the slider of the slider needle has a slider drive foot on its rear end pointing away from the working area, which projects above the surrounding areas of the slider in the vertical direction and is also suitable for engaging in a groove-like depression of a cam part.
  • the slider can also have more than one slider drive foot.
  • the slider drive foot and the needle drive foot usually engage in different groove-like recesses in the cam part.
  • the needle drive foot and the slider drive foot are suitable for absorbing the drive forces of a stitch-forming textile machine to drive the slider needle. The drive forces are advantageously provided by a cam part of a stitch-forming textile machine and transferred to the drive feet.
  • Slide needles are usually suitable for being guided in a groove-like needle channel of a stitch-forming textile machine.
  • both the needle body and the slider can be supported on the walls of the needle channel at least over sections of their longitudinal extension in the width direction.
  • the slider can have a slider shaft which adjoins its working area in the longitudinal direction and which has the same width in the width direction as the needle shaft.
  • the working area of the slider is tapered in the width direction compared to the width of the slider shaft in such a way that it can be inserted into the groove of the needle body.
  • the slider shaft is therefore wider than the working area of the slider.
  • the widened slider shaft also increases the stability of the slider.
  • Such slider needles are therefore particularly advantageous for use in high-speed stitch-forming textile machines.
  • the working area of the slider then usually has a width that is at most as large as the width of the groove or the distance between the shaft walls in the width direction.
  • a slider needle according to the invention is used in a stitch-forming textile machine, the slider needle advantageously engages in a further groove-like depression of a cam part, the cam part being suitable for transmitting a driving force acting in the longitudinal direction to the slider.
  • the slider needle can advantageously be moved in the width direction relative to the cam part.
  • the slider needle slides along in the groove-like depression and is moved in the longitudinal direction depending on the course of the groove-like depression. In this way, the movement of the slider needle can be controlled with the cam part.
  • at least the slider engages in a groove-like depression of the cam part. The movement of the slider can then be controlled via the cam part. Further advantages arise if the needle body also engages in a groove-like depression of the cam part.
  • the movement of the needle body can then also be controlled via the cam part. It is particularly advantageous if the slider and the needle body engage in different groove-like depressions of the cam part. The movement of the slider and the movement of the needle body can then be controlled independently so that they can move relative to each other.
  • the Figure 1 shows a slider needle 1 with a needle body 2 and a slider 10.
  • the needle body 2 has a needle shaft 3, the main direction of extension of which is in a longitudinal direction z.
  • the needle body 2 has a hook 4, which encloses a hook interior 5.
  • the hook 4 is suitable for forming half stitches 12 with a yarn during knitting. With the half stitch 12, a force 13 directed downwards in the vertical direction y can be exerted on the slider 10.
  • the hook interior 5 is open upwards in the vertical direction y.
  • the slider 10 is, however, displaceable in the longitudinal direction z in a groove 6 (see Fig.4-6 ) of the needle body 2 so that it can open and close the hook interior 5 depending on its relative position to the needle body 2.
  • both the slider 10 and the Each needle body 2 has a drive foot, the drive foot of the slider 10 being referred to as the slider drive foot 21 and the drive foot of the needle body 2 being referred to as the needle drive foot 20.
  • a drive force acting in the longitudinal direction z can be exerted on the needle body 2 and the slider 10 via the drive feet in order to control the movements of the needle body 2 and the slider 10 independently of one another.
  • Fig.2 three positions 30, 31, 32 of the slider needle 1 are shown, which typically occur when used in a stitch-forming machine during operation of the slider needle 1.
  • the representation of conventional machine elements known from the prior art, such as sinkers, is omitted.
  • Such elements can nevertheless be advantageously combined with the slider needle 1 according to the invention in stitch-forming machines, in particular for holding down and knocking off stitches.
  • the slider needle 1 according to the invention runs through the Fig.2 shown positions 30, 31, 32 in the order from left to right to form stitches. The order is symbolically shown by arrows 28 between the individual positions 30, 31, 32. Since the same slider needle 1 is shown in all positions, not all components of the slider needle 1 have been provided with reference symbols in every position shown for better clarity.
  • the half-stitch 12 exerts a force 13 directed downwards in the vertical direction y on the slider 10.
  • the slider 10 is pushed into the groove 6 (see Fig.4-6 ) of the needle body 3.
  • the hook interior 5 is opened and a yarn 24 is inserted into the hook interior 5.
  • the slider needle 1 makes a retraction movement 29 in the longitudinal direction z, by means of which the slider needle 1 is drawn further into the needle channel 23.
  • the slider 10 is moved relative to the needle body 2 in such a way that the slider 10 closes the hook interior 5 with its front end in the longitudinal direction z.
  • the half stitch 12 then slides during the drawing-in movement 29 along the needle shaft 3 and the slider 10 over the closed hook interior 5 and off the slider needle 1, which is connected to the Fig.2 shown intermediate position 31.
  • the sliding down of the half-stitch 12 from the slider needle 1 is also referred to by those skilled in the art as a throw-off because the half-stitch 12 in question then no longer has direct contact with the slider needle 1.
  • a loop is pulled through the half-stitch 12 and in this way a new half-stitch 12' is formed.
  • the previously formed half-stitch 12 thus becomes the stitch 26.
  • the new half-stitch 12' and the stitch 26 are shown in the illustration of the drawing-in position 32.
  • the slider needle 1 In the drawing-in position 32, the slider needle 1 is drawn the furthest into the needle channel 23. This means that the distance of the hook 4 from the needle channel 23 in the longitudinal direction z is the smallest in this position. In this position, the new half stitch 12' is still in the hook interior 5.
  • the slider needle 1 makes an expulsion movement 33 in the longitudinal direction z out of the needle channel 23.
  • the slider 10 is moved relative to the needle body 2 in such a way that the hook interior 5 is opened.
  • the slider needle 1 continues its expulsion movement 33 until it has reached its expulsion position 30 again.
  • the new half stitch 12' slides out of the opened hook interior 5 onto the needle shaft 3.
  • the stitch formation process described above starts again at this point. In this way, one stitch after the other can be formed to produce a knitted fabric.

  • the slider 10 is partially covered by the shaft wall 9. Its covered contours are shown in dashed lines for clarity.
  • the hook interior 5 of the slider needle 1 is shown closed. This means that the working area 11 of the slider 10 is positioned relative to the needle body 2 in such a way that it completely covers the opening of the hook interior 5.
  • a diagonally rising needle breast 17 adjoins the hook 4 in the longitudinal direction z.
  • the needle breast 17 is the area that limits the needle body 2 upwards in the height direction y.
  • the diagonally rising course of the needle breast 17 ensures a continuous, slow and therefore gentle widening of a half stitch 12 when it slides out of the hook interior 5 onto the needle shaft 3.
  • the needle body 2 has a groove 19 on its needle back 18, which limits the needle body 2 downwards in the height direction y.

  • the elevation height 25 is greater than zero if the elevation 15 projects above the slider 10 in the height direction y.
  • a half stitch 12 can slide over the elevation 15 as shown without coming into contact with the slider 10. This is particularly advantageous when the hook interior 5 is open, because it can prevent the half stitch 12 from touching the tip of the slider 10 and possibly being damaged by the tip.
  • Fig.3 As can be seen further, the elevation 15 is followed by a recess 14 in the needle body 2.
  • Fig.5 shows the section BB in the area of this recess 14.

  • the half-stitch 13 exerts a force 13 on the slide 10, which presses the slide 10 more strongly against the groove base 8 of the groove 6. This prevents a gap from forming between the groove base 8 and the slide 10 during operation, into which dirt and lint could penetrate.
  • a guide bar 16 is attached to the recess 14.
  • the height of the needle shaft 3 is increased in the height direction y. This area is therefore not suitable for coming into contact with a half stitch 12 during knitting. The half stitch 12 would then be widened too much.
