Definitions

  • the advantage of this solution is that micro-movements between the rigid cemented carbide insert and the relatively more elastic gripper body are possible.
  • the gripper body remains flexible, bending stresses being largely kept away from the cemented carbide insert.
  • the solution finds its limitations when the use is very brittle, so that it could be damaged when deforming the edge of the bag.
  • the coating applied in the pocket thus forms a wear protection element, which is comparable in terms of wear protection effect to the hard metal elements used in the earlier prior art.
  • the wear protection element is applied by a spraying method such as plasma spraying, flame spraying, arc spraying. It is liable by itself without the aid of auxiliaries. No solder or glue is required. Also, no subsequent mechanical machining operations, such as plastic deformation of the edge of the pocket, are required to secure the wear protection element.
  • the narrow side 10 is limited seen from below a loop receiving space 12, which is bounded on the one hand by the hook-like end 7, at the top by the narrow side 10 and at the end 7 opposite side by a step 13.
  • the loops 11 received by the loop receiving space 12 can be cut open, for example by a suitable knife, if cutting pile is to be produced in the course of a tufting process.
  • a suitable knife is in Fig. 1 indicated by its dashed contour 14. It has on its front side a cutting edge, with the loop 11 can be cut in cooperation with the loop taker.
  • the wear protection element 15 is formed by a sprayed coating which preferably completely fills the pocket 16, i. the floor 18 completely covered.
  • the coating has a flush surface 5 with the flat side surface 19, which is preferably also flat.
  • FIGS. 5 and 6 show variants of different embodiments of the pocket 16, the edge 17 and the wear protection element 15a, 15b.
  • the edge 17 need not necessarily be formed as a steep step. He may also be formed flat leaking, such as Fig. 5 suggests.
  • the surface 19 may also be slightly below the side surface 5 and connect by a rounding at its edge yet flush to the side surface 5, such as Fig. 5 also indicates.
  • FIG. 7 shows another embodiment of a tool which is used for example in the manufacture of carpet with velor-like surface use.
  • the tool cuts the loops produced and thus acts like a knife.
  • the knife has a tool body 2, the front portion of which forms a section 3 for the processing of loops and the rear portion of which forms a holding or fastening section 4.
  • the section 3 is rectangular in shape and essentially forms the extension of the fastening section 4.
  • the section 3 is bounded by the flat side surfaces 5 and 6 and by the narrow sides 8 and 10 and its end 7. At the end 7, a cutting edge 20 may be formed.
  • the narrow side 10 and the end 7 are connected to each other via a narrow side 23.
  • the narrow side 23 is to the narrow side 10 and the end 7 at an angle to each other. The result is a recess which serves to optimize the cutting function of the tool 1, since this is arranged at an angle to the loop taker 1 in the tufting machine.
  • the tool 1 is provided with a wear protection element 15, which protects or forms the special stress exposed areas of the side surface 5 of the narrow side 10 and in particular of the end 7.
  • the wear element 15 is mounted in a corresponding region 22 of a corresponding pocket 16 of the main body 2.
  • This pocket 16 extends as a shallow recess over the side surface 5 and is bounded by an edge 17, which is formed for example by a step.
  • the edge 17 connects the narrow sides 10 and 8 so that the pocket 16 occupies the entire width of the tool 1.
  • the width of the tool 1 the distance of the narrow side 10 is considered to the narrow side 8.
  • the bag 16 is a three-sided open pocket, longitudinally is limited by the edge 17.
  • a tool 1 which has a wear-reducing coating on its tool base body 2, which serves as a wear-protection element 15.
  • the tool body 2 is provided at a suitable location with a recess on the bottom of which the coating is built up, for example, by plasma spraying.
  • the coating used is preferably an oxide-ceramic material.
