Definitions

  • the invention relates to a knitting tool holder with a plurality of knitting tools, each of which has a working area, a fixing area and two narrow sides pointing in opposite directions, wherein the knitting tools are arranged parallel to each other and at a predetermined distance from each other between two cover boards.
  • Such a tool holder is out DE 677 602 C known.
  • the cover plates have grooves, in which the knitting tools can be inserted.
  • a knitting tool holder In knitting machines, it is often customary to combine several knitting tools in a knitting tool holder.
  • a knitting tool holder then often has a width of one or two inches and, depending on the fineness, a correspondingly large number of knitting tools.
  • knitting tool here is a short name for those elements of a knitting machine, in particular a warp knitting machine, which are involved in the stitch formation in producing a knitted fabric. It is therefore not only the actual knitting tools, such as knitting needles, slides, sinkers and the like, but also to thread guide elements, such as hole needles, comb boards or the like.
  • DE 196 18 368 B4 describes a knitting tool holder with a carrier having a groove.
  • the groove is filled with a curable filling material, in which the knitting tools are used, as long as the filling compound is not yet cured.
  • the invention has for its object to provide a knitting tool, which requires a small space with high rigidity.
  • the knitting tools with the desired pitch are arranged side by side and positioned, for example in a corresponding teaching. You can then apply an adhesive on a narrow side of the knitting tools or on one side of a cover plate and then the cover plate stick with the knitting tools. The same process then repeats itself on the other narrow side. Of course, you can run both gluing at the same time. The result is a sandwich-like composite of the two cover plates and the knitting tools. The bonding of the knitting tools on the narrow sides is surprisingly sufficient to provide a knuckle tooling available that has a low mass and in any case after attachment of the knitting tool holder to the corresponding knitting tool bar sufficient rigidity.
  • Each knitting tool preferably has a shank in the attachment area and the cover boards are glued to the shank. This creates a defined investment area for the cover plates on the knitting tools. This facilitates the production.
  • the shaft has on at least one narrow side a projection which projects beyond an end face of the cover plate, wherein the projection has a contact surface which is glued to the end face.
  • the projection may be formed so that it covers only a part of the thickness of the front side, so that a corresponding small adhesive surface is formed. But it can also be designed so large that the contact surface has an extension which is at least as large as the extension of the front side. In this case, the adhesive connection is made over the maximum possible area.
  • the knitting tool is then held, so to speak, in two different directions in the knitting tool holder. Thereby results in an increased stability.
  • the assembly is facilitated because the projection defines a position at which the cover plate can be brought to bear.
  • the projection comprises the outside of the cover plate, wherein the projection on the outside of the cover plate is glued to the cover plate.
  • the projection has a small groove which is slightly larger than the thickness of the cover plate. The cover plate is then inserted into this groove, so that the knitting tool, the cover plate in the region of the projection U-shaped surrounds.
  • three adhesive surfaces between the knitting tool and the cover plate are available with each knitting tool, which results in a very high stability.
  • a spacer is arranged between the cover plates, which has a thickness which corresponds to a distance between the narrow sides in the attachment region of the knitting tools.
  • the cover plates are connected to the spacer, for example also by gluing.
  • the cover plates are not only attached to the knitting tools, but also on the spacer on which the cover plates can create surface. This results in a very high stability of the active tool holder.
  • the spacer ends at a side facing away from the working area end of the shaft.
  • the area between knitting tools is therefore not filled by any additional parts or elements of the spacer.
  • the spacer is made of a light metal or a plastic.
  • the mass increase can be kept small by the spacer.
  • the spacer forms at least one stop. If you mount the knitting tool holder on a knitting tool bar, then the stopper helps with the positioning.
  • the stop is guided through a cover plate.
  • the cover plate has the advantage that the spacer and the cover plates can still positively connect with each other, which further increases the stability of the active tool holder.
  • the stop projects on the side facing away from the knitting tools from a space between the cover plates.
  • the spacer can be designed with a simpler contour.
  • the distance between the narrow sides is greater than the sum of the thicknesses of the cover boards.
  • the size of the knitting tool holder can be kept very small.
  • the cover plates contribute virtually nothing to a significant increase in size.
  • the coversheets are formed of a sheet material having a thickness in the range of 0.1 to 0.8 mm.
  • the cover plates can be practically designed as films. Although the coversheets are very thin, they can ensure sufficient stability due to the bond with the knitting tools.
  • the sheet material steel or plastic optionally reinforced with fibers.
  • the surface material only has to have sufficient tensile strength in order to be able to withstand the stresses during operation of the knitting machine.
  • the knitting tools preferably protrude a maximum of 10 mm from the cover plates. Thus they have only a relatively short free length, in which they can be deformed. This keeps on the one hand the effort when reworking small, for example, when straightening knitting tools. On the other hand, the adhesive connection between the knitting tools and the cover plates is claimed only relatively low, because only a short lever arm is available.
  • the active tool holder is constructed symmetrically to a plane between the cover plates. So you have to pay attention during assembly of the active tool holder no special orientation of the active tool holder against the knitting tool bar.
  • Fig. 1 shows a knitting tool holder 1 with a plurality of knitting tools 2, which are arranged parallel to each other and at a predetermined distance 3 to each other. From the effect tools 2 you can in Fig. 1 only recognize a narrow side 4. If you have the in Fig. 1 Assigns visible narrow side 4 a front, then there is a corresponding narrow side 5 at the back. The narrow sides 4, 5 thus have in opposite directions.
  • the knitting tools 2 which are present here in the form of hole needles, flat. You can for example be punched from a sheet of appropriate thickness.
  • the knitting tool holder has two holes 6, 7, can be guided by the screws with which the knitting tool holder 1 can be attached to a knitting tool not shown.
  • the knitting tool holder 1 has a width of, for example, 1 or 2 inches. Since it is possible to arrange the holes 6, 7 relatively far apart from one another, this results in a good alignment possibility of the knitting tool holder 1 on the knitting tool bar.
  • the knitting tool holder 1 is formed like a sandwich.
  • a first cover plate 8 is glued to the front narrow side 4 of the knitting tool 2.
  • a second cover plate 9 is glued to the narrow side 5 at the back of the knitting tool 2.
  • the terms "front” and “back” are used here only to facilitate the explanation.
  • the knitting tool holder 1 is formed symmetrically to a plane between the two cover plates 8, 9, so it can in the illustrated orientation or in a direction offset by 180 ° to be mounted.
  • the knitting tool 2 has a working area 10 and a fastening area, which is formed here by a shaft 11.
  • the cover plates 8, 9 are glued only in the region of the shaft 11 with the knitting tool 2.
  • an adhesive 12 between the shaft 11 and the cover plates 8, 9 is arranged in each case.
  • the spacer 13 has a thickness which corresponds to the distance between the two narrow sides 4, 5 in the region of the shank 11, that is to say in the fastening region. Accordingly, the two cover plates 8, 9 may be flat over their entire extent.
  • the cover plates 8, 9 are connected to the spacer 13 surface, for example by gluing. But they can also be point or line connected to the spacer 13.
  • the cover plates 8, 9 are formed of a relatively thin sheet material.
  • they may be formed as steel foils having a thickness between the range of 0.1 to 0.8 mm, preferably in the range of 0.1 to 0.5 mm.
  • Both steel and fiber-reinforced plastics have a relatively high tensile strength, so that the adhesive bond between the end faces 4, 5 and the cover plates 8, 9 is sufficient to keep the knitting tools 2 reliably in position.
  • the spacer 13 may also be formed of a plastic. You can also use a light metal. Of course, the holes 6, 7 also penetrate the spacer 13.
  • the spacer 13 has a pair of stops 14, 15, that is to say a stop 14 on the front side and a stop 15 on the rear side. Another pair of stops, of which only one stop 16 can be seen on the front, can be provided in the region of the other edge of the knitting tool holder 1.
  • the stops 14, 15 are guided through corresponding openings 17, 18 in the cover plates 8, 9. They cause a positive connection between the spacer 13 and the cover plates 8, 9th
  • the spacer 13 has at its the knitting tools 2 edge facing no profile, but it is smooth. In particular, there are no elements or projections of the spacer 13, which protrude into the interstices 3 between the knitting tools 2. These gaps 3 are between the cover plates 8, 9 free.
  • the stops 14, 15 can be used as an aid to position the knitting tool holder 1 on the knitting tool bar.
  • Fig. 2 It is shown that the adhesive 12 protrudes slightly beyond the knitting tool 2 inwardly between the cover plates 8, 9. This will come in many cases can not be avoided, but is not necessary in principle.
  • Fig. 3 shows a modified embodiment, which differs from that of Fig. 1 and 2 differs in that the spacer 13 has stops 19, 20 which protrude on the side facing away from the knitting tools from a space between the cover plates 8, 9.
  • the knitting tool holder 1 after Fig. 3 also has a material recess 21 which is used for mass reduction.
  • Fig. 4 shows a side view of the knitting tool holder 1 Fig. 3 ,
  • Fig. 5 shows a modification of the knitting tool holder 1 after Fig. 4 ,
  • the knitting tool 2 has at its the work area 10 facing the end of the shaft 11 at the Front 4 a projection 22 and on the back 5 a projection 23.
  • the projections 22, 23 each form a contact surface 24, 25.
  • the contact surface 24, 25 has an extension in a direction from the front 4 to the back 5, which is greater than the thickness of the cover plates 8, 9.
  • Knitting tool 2 also in the area of the contact surfaces 24, 25 with end faces of the cover plates 8, 9 to glue. This results in an adhesive connection in two different directions, namely once along the longitudinal extent of the knitting tools 2 and once across it. This results in increased strength and thus improved rigidity.
  • Fig. 6 shows one opposite Fig. 5 modified embodiment of a knitting tool holder 1 in side view.
  • the projections 22, 23 of the knitting tool 2 each have a groove 26, 27, so that the projections 22, 23 can cover the cover plates 8, 9 in a U-shape.
  • These grooves 26, 27 are formed so that the cover plates 8, 9 can be inserted with little play. This game is so large that you can still accommodate an adhesive between the cover plates 8, 9 and the walls of the grooves 26, 27, so that the knitting tool 2 with the cover plates 8, 9 along the walls of the groove 26, 27 can be glued ,
  • the cover plates 8, 9 are, as stated above, very thin.
  • the distance between the narrow sides 4, 5 in the mounting area, ie on the shaft 11, is greater than the sum of the thicknesses of the cover plates 8, 9. Accordingly the thickness of the knitting tool holder 1 is determined mainly by the width of the knitting tools.
  • the cover plates 8, 9 hardly contribute to the thickness.
  • the cover plates 8, 9 are not thicker than the knitting tools. 2
  • the knitting tools 2 are at most 10 mm from the cover plates 8, 9 before, preferably even only 5 mm or less. This results in a relatively short free lever arm on the knitting tools 2, so that moments that could lead to a loosening of the adhesive bond between the knitting tools 2 and the cover plates 8, 9, also can be kept small. In addition, the risk of deformation of the knitting tools 2 and the associated need for alignment of the knitting tools 2 is small.
