Definitions

  • the invention relates to a tool, in particular a knitting tool for the assembly of ingots in textile machines, in particular knitting machines.
  • a knitting tool for the assembly of ingots in textile machines, in particular knitting machines.
  • Under knitting tool is understood here a tool for the production of knitted fabric, in particular a knitting needle.
  • Textile machines e.g. Tufting machines, stitchbonding machines or knitting machines have bars with tools for producing textile surfaces.
  • a tool according to the invention can be held by a bar of such a or a similar textile machine.
  • Knitting machines usually have at least one bar which contains many knitting tools, e.g. Holding needles in parallel alignment.
  • the barre is an elongated carrier which extends transversely to the knitting tools and performs a predetermined movement. All the knitting tools resting on the support perform the same movement.
  • the knitting tools are held to the bar at certain distances from each other. These distances determine the division.
  • a measure of the division is the so-called fineness, which is stated in number of knitting tools per English inch.
  • the fineness E40 designates 40 needles per English inch.
  • the bar has a slot for each knitting tool in which the knitting tool is held and clamped.
  • units can be achieved from E40 to E44. At higher subtleties, this concept comes up against the limit.
  • the existing between the slots web walls and / or the tool shanks are so thin that they are no longer able to cope with the mechanical requirements.
  • the bar receives the knitting tools clamped between a bed and a clamp. Both the bed and the clamping piece are provided with a flat toothing.
  • the toothing is formed by triangular cross-section grooves whose width exceeds the width of the knitting tools.
  • the knitting tools are tapered wedge-shaped on their narrow sides in order to better find their way into the triangular grooves.
  • the knitting tool according to the invention has on its body a positioning means with which it can be positioned according to a predetermined pitch.
  • the positioning means makes the previously provided between the knitting tools web walls superfluous. It positions that Knitting tool on the bar regardless of web walls or channels, as they were previously required to accommodate the tool shanks. As a result, the space previously used for the web walls is now available for the ceiling of the knitting tool bodies or their tool shanks which form bearing sections. Very high finenesses of, for example, E50 can be achieved without problems with the rigidity or strength of the knitting tools.
  • the provided on the knitting tool positioning serves to bring the knitting tool with respect to its transverse direction in a defined position and set in this position.
  • the positioning means is formed by at least one projection provided on the body.
  • This projection is formed by a longitudinally extending rib on the body.
  • This rib is preferably arranged on a narrow side of the body.
  • a groove is provided on the bar, in which fits the rib.
  • At the barre are go stunt.yakere Provided grooves which are oriented parallel to each other and determine the pitch of the needles.
  • the grooves are narrower than the tool shanks or bearing sections. They serve only to receive the ribs.
  • the knitting tools at least in the region of its stitch-forming part has a width which is smaller than the width of the bearing portions which are held on the bar.
  • width is understood to mean the distance of the side surfaces of the respective bearing section or of the stitch formation section transversely to the longitudinal direction to the knitting tool. The transverse direction is parallel to the longitudinal extent of the bar. But it is also 'possible to provide knitting tools whose mesh-forming part has the same width as the bearing section or is slightly larger. This is possible when alternately knitting tools are provided on the bar, the mesh-forming parts have different spatial orientations, eg by pointing alternately obliquely upwards and obliquely downwards.
  • the stitch forming portion may include a shaft that terminates in a hook at the end.
  • the shaft can have a uniform or different heights. The height is measured perpendicular to the longitudinal direction of each needle.
  • a slot may be provided, for example, for a slider. This can be held on a different bar, wherein, this slide can be designed according to the same principle as a needle and held in the bar. The slides, the needles or other mesh forming elements are thus knitting tool in the sense of the claims.
  • FIG. 1 is a barre 1 of a knitting machine illustrated.
  • knitting tools 2 here exemplified by means of needles 3, shown.
  • the needles 3 are held in parallel alignment next to each other on the bar 1.
  • Each knitting tool 2 has, as FIG. 2 can recognize, a working section 4 and a bearing section 5.
  • the working portion 4 has a stitch forming portion, a stitch forming portion.
  • the working sections 4 are narrower than the bearing sections 5, ie they have a smaller width.
  • the width is to be measured in the transverse direction Q, which coincides with the longitudinal direction of the bar 1 and is perpendicular to the longitudinal direction L of each knitting tool. Because of the smaller width of the working sections 4 is between the working sections 4 adjacent knitting tools 2 even then a sufficient gap 6 and a free space available when the bearing sections 5 are very close to each other or with their flat side surfaces 7, 8 abut each other.
  • a narrow gap 9 may be present between adjacent side surfaces 7, 8, a narrow gap 9 may be present. This can be in the range of a few microns up to about a tenth of a millimeter or, if necessary, be sized larger.
  • the gap 9 is preferably empty, ie open. In individual cases, it may also be useful to arrange in the gap further elements, such as elastically or plastically resilient damping elements or the like. In any case, no elements are provided in the gap 9, which would pretend or define the division of the knitting tools 2.
  • the pitch denotes the center distance T of adjacent knitting tools 2. The higher or greater the fineness E, the smaller the pitch T. In the present exemplary embodiment, the pitch T is, for example, 0.5 mm (approximately E50).
  • a positioning means 11 is provided on the body 10 of the knitting tool 2.
  • the positioning means 11 is formed by a recess extending in the longitudinal direction L in the form of a slot 12, which leads from the needle top, a narrow side 13 of the bearing portion 5, starting in the body 10.
  • the slot 12 is preferably limited to the bearing section 5.
  • the end provided, for example, with a hook 14 working section 4 of the knitting tool 2 protrudes from the bar 1 out and so far contains no positioning. It may be provided with a slot 15, for example, for receiving a slider (not shown) and thus is part of the stitch formation system.
  • the bar 1 has a preferably flat bearing surface 16 against which the bearing section 5 rests with its narrow side 13.
  • FIG. 1 and 4 let recognize the knitting tools 2 are clamped by a clamping bar 24 against the support surface 16.
  • the clamping strip 24 presses, for example via a damping element 25 against the back, a narrow side 26 of the knitting tool. 2
  • a foot 27 can be provided on the bearing section 5, which preferably protrudes away from the narrow side 13 of the bearing section 5 having the slot 12.
  • the foot 27 fits into an axial positioning groove 28 which extends in the transverse direction Q along the bar 1.
  • the setting of the corresponding division thus comes about through the interaction between the positioning means 11 and the fixing means 29.
  • FIG. 5 illustrates a tool according to claim 1.
  • the positioning means 11 is formed by a projecting from the lower narrow side 13 of the bearing portion 5 preferably longitudinal rib 32 which is narrower than the width of the bearing portion 5, which is the distance between the Side surfaces 7, 8 to measure.
  • the rib 32 engages in a groove 33 which is provided in the bar 1 and forms the fixing means 29.
  • the adjacent bearing sections of adjacent knitting tools 2 are arranged close to each other except for a slight gap 9.
  • the working section 4 and the bearing section 5 are aligned. It should be noted, however, that the sections can not only be offset from each other in parallel but can also be arranged at an angle to one another.
  • the working portion 4 may be formed cranked in any desired direction.
  • the working section 4 of the knitting tool comprises the stitch-forming region of the knitting tool 2 and can be of different lengths depending on the application.
  • One end of the stitch forming area 4 comprises the end of the knitting tool 2 when formed as a needle 3, the hook 14, the other end of the stitch forming area 4, depending on the application before, exactly on the border to or in the storage section 5 end.
  • a knitting needle or other knitting tool 2 designed in particular to achieve particularly fine pitches has a narrower working section 4 and a wider bearing section 5, wherein the bearing section 5 is provided with the positioning means 11 in the form of a rib 32.
  • the knitting tool 2 is assigned a fixing means 29 in the form of a groove 33 on the part of the bar 1.
