Definitions
- the invention relates to a machine knitting needle for use in a knitting machine, for example a circular knitting machine.
- Machine knitting tools are known in different configurations.
- Machine knitting needles for example latch needles or compound needles
- a lock of the knitting machine acts on a foot part of the machine knitting tool in order to position or move the machine knitting tool in its longitudinal direction.
- the knitting cylinder with the machine knitting needles is rotated relative to the lock in a circumferential direction, or vice versa, and the foot parts of the machine knitting needles are guided in a lock path.
- Other machine knitting tools such as sinkers or slides of compound needles, are moved or positioned by means of a suitable drive device during knitting in a knitting machine.
- the machine knitting tools In order to meet the requirements of a productive knitting process and, on the other hand, to ensure a long service life, the machine knitting tools must meet a large number of, in some cases, competing conditions. High productivity requires high movement speeds or accelerations of the machine knitting tools. As a result of these accelerations, no excessive signs of wear such as fatigue fractures on the machine knitting tool must occur. Replacing a defective machine knitting tool requires the knitting machine to stop and leads to a loss of productivity. It is just as important that the machine knitting tool can be positioned precisely so as not to cause any errors in the formation of the loop. This positioning accuracy must not be disturbed by impurities that can accumulate in the guide or needle channel, especially in the channel base. In order to do justice to these various boundary conditions, the machine knitting tool as a whole must have a design that takes all aspects into account and fulfills them as well as possible.
- U.S. 5,154,069 A discloses a machine knitting needle with a shaft part and a foot part projecting away from the shaft part for moving the machine knitting needle. Between a front end of the machine knitting needle and the foot part, the shaft has a multi-curved, arch-shaped, resilient section. This section is intended to have a dampening effect when accelerations occur. Also are out U.S. 5,231,855 A or DE 69 218 303 T2 Meandering shaft sections are known in order to dampen the influence of jerky accelerations on the machine knitting needle and to avoid damage.
- the relevant section of the shaft part has no contact with the base of a needle channel of a knitting machine in these sections serving for damping, so that impurities can collect.
- the relevant section of the shaft part has no contact with the base of a needle channel of a knitting machine in these sections serving for damping, so that impurities can collect.
- machine knitting tools which have a short overall length, there is the problem that such an arcuate or meandering shaft section reduces the effective working length of the machine knitting tool available for loop formation and holding one or more loops on the shaft.
- DE 2 229 858 A discloses a latch needle for knitting machines.
- the latch needle has two foot parts which are arranged at a distance from the latch needle in the longitudinal direction and a separating zone which is arranged between them and extends down to below the level of the upper edge of the needle shaft.
- this foot part section of the latch needle, in which the two foot parts are arranged can additionally on the underside grooves of the needle shaft are present.
- grooves can be present in the transition from the foot parts to the shaft part on the upper side of the needle shaft. This weakening of the needle shaft in the foot section is intended to dampen shocks caused by the acceleration of the needle, which is introduced via the foot sections.
- GB 2074614 A describes a punched knitting needle that is designed as a latch needle.
- the latch needle has recesses that penetrate transversely through the shaft and are delimited all around by webs remaining on the shaft.
- U.S. 4,036,036 A relates to a latch needle with a shaft which is pierced in the transverse direction by at least one slot and / or at least one hole in order to achieve a damping effect.
- DE 2610078 A1 relates to a latch needle with a shaft assembled from several shaft parts.
- the shaft parts are positively connected to one another.
- EP 1 229 158 A1 discloses a compound needle with a needle shaft and a slide which is mounted displaceably guided in a longitudinal recess of the needle shaft.
- the machine knitting needle according to the invention is a latch needle.
- the machine knitting needle has a shaft part which extends in a longitudinal direction and which has a bearing surface on an underside.
- the support surface is set up to rest on the base of a guide or needle channel in a knitting machine.
- the shaft part has a front end to which a front end section is connected. In the front end section the shaft part has a means for loop formation, in particular a needle hook.
- the shaft part has a rear end opposite the front end portion in the longitudinal direction. Outside the front end section, the support surface extends continuously to the rear end within a single plane - wherein the support surface can merge with a radius into the rear end.
- the shaft part has a total length from the front end to the rear end which is preferably a maximum of 100 mm.
- the front end section which is set up for loop formation, has a maximum length of 5% of the total length of the shaft part.
- the front end section preferably does not extend beyond the tongue bearing and ends, for example, between the needle hook and the tongue bearing.
- the machine knitting needle has a front guide section in which a guide arm protrudes in a height direction away from the shaft part, and a rear guide section in which a further guide arm protrudes in the height direction away from the shaft part. Between the two guide sections there is a foot section in which a foot section protrudes from the shaft section in the vertical direction.
- the foot part is designed to work together with a lock or another drive of a knitting machine in order to move the machine knitting needle in the longitudinal direction within a needle or guide channel of the knitting machine.
- Each guide arm has an arm limb which, with the area of the shaft part arranged below it in the vertical direction, delimits an intermediate space which is open in the longitudinal direction on the side facing away from the foot part.
- the boom leg can extend parallel to the longitudinal direction or at an angle of inclination of less than 15 degrees or 10 degrees relative to the longitudinal direction.
- the guide arm and the shaft part form, so to speak, a fork-shaped area of the machine knitting needle in the respective guide section.
- the machine knitting needle Due to the inventive design of the machine knitting needle with a continuous flat support surface, which is in particular free of elevations or depressions or perforations, there is no space available in the area of the needle shaft in which impurities can collect and the alignment or guidance of the machine knitting needle in the guide channel or Can affect the needle channel. It also avoids that by an accumulation of dirt, increased friction or increased wear and tear occurs when the machine knitting needle moves in the guide channel.
- the machine knitting needle is designed and suitable in particular for knitting a staple yarn or a cotton yarn. With such yarns, a particularly high level of soiling occurs in the knitting machine due to yarn remnants from the staple fiber yarn. The machine knitting needle is therefore particularly insensitive to such soiling and is particularly suitable for knitting such yarns.
- guide sections are provided on both sides of the foot part or the foot part section, wherein the distance between the guide sections from the foot part or from the foot part section can be the same or different.
- both guide sections can directly adjoin the foot section.
- one of the guide sections and in particular the front guide section can directly adjoin the foot section, while an intermediate section can be located between the other guide section and in particular between the rear guide section and the foot section.
- the guide arms support the needle against forces occurring in the vertical direction and / or in a transverse direction which is oriented at right angles to the height direction and at right angles to the longitudinal direction.
- the intermediate space between the boom leg and the area of the shaft part located therebelow creates a spring-elastic effect when forces act on the boom leg in the vertical direction. These forces therefore do not act directly on the shaft part, but can be at least partially elastically received or supported in the guide arm. This results in very precise guidance and positioning of the machine knitting needle.
- the refinements can also reduce tilt tendencies about an axis extending in the transverse direction and / or an axis extending in the longitudinal direction.
- each guide arm has a connecting leg which connects the arm leg to the shaft part.
- the connecting leg can include an angle of inclination with respect to the longitudinal direction which has an amount in the range from approximately 20 degrees to approximately 90 degrees, preferably from approximately 25 degrees to approximately 65 degrees.
- the connecting leg of each guide arm preferably extends obliquely from the shaft part and at the same time away from the foot part.
- each guide arm in a transition section to the shaft part has a width which is at least twice as large as the maximum shaft height of the shaft part.
- the width of the guide arm is measured lengthways in the transition section.
- the shaft height of the shaft part is the distance between the bearing surface on the underside and an upper side of the shaft part that is opposite in the vertical direction.
- the width of the guide arm in the transition section is twice as large as the shaft height in the respective guide section.
- the boom leg can have a width at right angles to its direction of extension which is as large as the shaft height of the Shank part in the respective guide section.
- the shaft height is preferably constant in each guide section.
- the boom leg of the rear guide boom has a free end which has the same position in the longitudinal direction as a rear end of the shaft part.
- the arm leg of the rear guide arm and the shaft part are flush with one another. It is thereby achieved that the guide sections or the guide arms have the greatest possible distance from one another in the longitudinal direction without increasing the overall length of the machine knitting needle.
- the distance between the front guide arm and the foot part can be smaller than the distance between the rear guide arm and the foot part.
- the front guide arm can be arranged as close as possible to the foot part in order to maximize an effective working length of the shaft part from the front end section to the front guide arm.
- a front shaft portion of the shaft part can be connected to the front end portion, which is at least partially protruded from the front guide arm.
- This front shaft section is ready for receiving a loop, which can slide along the front shaft section in the front end section and in the front shaft section up to the connection point of the front guide arm with the shaft part, with a maximum of about half the length of the front shaft section for receiving stitches in conventional knitting processes is used. In one embodiment, half the length of the front shaft section is set up to receive stitches.
- the foot part can have a transition area to the shaft part Have foot part base, the length of which in the longitudinal direction is smaller than the length of an upper foot part area of the foot part adjoining in the height direction.
- the foot part base can for example form a constriction of the foot part in the longitudinal direction. This measure makes it possible to reduce a load which acts on the foot part when a force is introduced to accelerate the machine knitting needle in the longitudinal direction.
- the damping effect can be further improved in that the bearing surface rests over the entire or almost the entire length of the shaft part in the guide channel of the knitting machine.
- a base height of the foot part base is greater than a shaft height in the guide sections. Additionally or alternatively, the base height can be smaller than the guide jib height of the guide jib.
- the guide boom height is the maximum distance between an upper side of the boom leg and the underside of the shaft part.
- the base height is the height of the foot part base starting from the adjoining upper side of the shaft part. The foot part base and the adjoining upper foot part area merge at the point at which the foot part has reached its maximum length in the longitudinal direction.
- the foot part base has a curved section on each of its two longitudinally opposite sides.
- the curved section facing the front guide section can merge directly into the front guide bracket and in particular the connecting leg of the front guide bracket.
- the rear guide boom is preferred at a distance from the curved section of the foot part base facing it.
- At least one or both of the curved sections can have a constant radius of curvature or a changing radius of curvature.
- the changing radius of curvature can be greatest in the region of the curved section which, viewed in the height direction, adjoins the shaft part.
- the foot part has at least one foot part recess.
- the foot part recess can be arranged at a distance from the shaft part in the height direction and is located in particular outside the foot part base exclusively in the upper foot part area.
- the foot part recess viewed in the vertical direction, can be open on the side opposite the shaft part.
- the total weight of the machine knitting needle can be reduced by the at least one foot part recess. If the foot part recess extends completely outside of the foot part base, an excessive weakening of the foot part can be avoided, since forces that frequently change in the longitudinal direction act on the foot part to accelerate the machine tool.
- the shaft part in the foot part section can have a shaft part height that is a maximum of 1.1 mm.
- the shaft part height in one or both guide sections is smaller or at most as large as the shaft part height of the shaft part in the foot part section.

- the shaft part 12 has in the height direction H on an underside, a support surface 20 which extends predominantly in a single plane E and, apart from a roughness, has no projections or depressions with respect to this plane E. Only in the front end section 18 and in a transition radius to or at the rear end 14 can the underside of the shaft part 12 deviate from the extent from the plane E, for example in order to set up the front end section 18 for loop formation, in particular to form the needle hook 15.
- At least the underside of the shaft part to form the bearing surface 20 is designed so that it extends continuously without a recess within the plane between the foremost point at which the underside of the shaft part lies in plane E and the rearmost point at which the underside of the shaft part lies in plane E E extends.

However, the free length of the shaft part 12 in the front shaft section 19 dampens shocks and vibrations, which in particular via the foot part 27 into the Machine knitting needle 11 are initiated.
- the machine knitting needle 11 can pass through the lock and / or the opposite channel walls of the guide or needle channel in the transverse direction Q at points spaced apart from one another in the longitudinal direction L both in the height direction H and in the transverse direction Q a knitting machine are supported.
- centrifugal forces occur due to the rotation of the knitting cylinder relative to the lock, as well as forces acting laterally on the foot part 27.
- the machine knitting needle 11 is accelerated in the longitudinal direction L through the lock path of the lock by means of the foot part 27.
- the forces acting in the longitudinal direction on the foot part 27, which are introduced in particular via the two foot part edges 30, 31, can be dampened, so that the stress on the machine knitting needle 11 is reduced and deviations in the positioning accuracy during loop formation are reduced become.
- the guidance and positioning of the machine knitting needle 11 is further supported by the guide arms 47, the arm legs 49 of which extend in the height direction H at a distance from the shaft part 12, forming an intermediate space 50.
- the boom legs 49 can move elastically relative to the region of the shaft part 12 lying therebelow. Forces acting in the height direction H on the boom legs 49 through the lock are therefore at least partially absorbed by the elasticity of the boom legs 49.
- the machine knitting needle 11 in a guide or needle channel of a knitting cylinder with the support surface 20 rests very well on the base of the needle channel or the guide channel.
- This improvement in the positioning accuracy is also improved in particular by the fact that the bearing surface 20 is free of depressions and recesses in which dirt can collect during knitting. This is particularly advantageous when knitting with staple yarns.
- the invention relates to a machine knitting needle 11 with a shaft part extending in a longitudinal direction L and having a support surface 20 on an underside. Outside of a front end section 18 set up for loop formation, the support surface 20 extends continuously in a plane E up to the transition into the rear end 14 of the shaft part 12 opposite the front end section 18. Between a front guide section 45 and a rear guide section 46 there is a foot section 26 a foot part 27 is present. In each guide section there is a guide arm 47 which projects away from the shaft part 12 in a height direction H and delimits an intermediate space 50 between a arm leg 49 of the guide arm 47 and the area of the shaft part 12 arranged below it.
