Definitions

  • the bearing shafts of the sectional warp beams are divided in corresponding sections to enable the operator to put the heavy yarn beams in the machine by hand or mechanically. These bearing shaft sections are afterwards coupled in the machine and driven simultaneously by a yarn supply gear.
  • Another object of the invention is to facilitate the mounting and dismounting ofthe individual sections of the beam shaft.
  • the coupling is rigidly connected with the associated end of a shaft section, and the end of the adjacent shaft section is provided with a peg adapted to be inserted into the coupling and clamped by a cover or a half shell of the coupling.
  • FIG. I shows, with a considerable reduction of scale compared to the other figures, the general layout of two sectional warp beams,
  • FIG. 2 is a sectional elevational view oh an enlarged scale of the coupling zone of FIG. 1,
  • FIG. 3 is a sectional side view of FIG. 2 as seen from the left.
  • FIG. I Two bearing shaft sections 1 and 2 of a sectional warp beam are shown in FIG. I to be journaled on the right side in a bearing 3 and on the left side in a bearing 4.
  • the left section is driven by a yarn feeding gear 5.
  • Both abutting sections are connected by a central coupling 6.
  • FIGS. 2 and 3 show details of the coupling according to the invention. Both ends ofthe bearing shafts l and 2, designed as hollow shafts, are provided with a rigidly attached end cover 7 and 8, respectively. One half 9 of a sleeve coupling is connected to the end cover 8 by screws 10 and has a receptacle for the peg II of the end cover 7. The unit formed by parts 8 and 9 is supported by a ball bearing 12 in the central traverse 13.
  • the coupling 9 is rigidly mounted to the shaft section 2, while the peg 11 of shaft section I is inserted into the coupling and clamped by the cover or shell 14. This is effected by screws 15.
  • This design results in a very narrow central traverse l3 and also a narrow coupling 9.
  • the two sectional warp beams (not shown) can be arranged with an extremely small mutual distance.
  • the shell 16 for the ball bearing is unscrewed and the shaft is removed transversely upward.
  • a warp knitting or Raschel machine comprising sectional warp beams supported by corresponding hollow shaft sections, end covers rigidly attached to adjacent ends of said shaft sections, one of said end covers being provided with a cylindrical peg, one half of a sleeve coupling connected to the other of said end covers and having a substantially semicylindrical receptacle for said cylindrical peg, and a substantially cylindrical shell or cover adapted to be screwedl on said coupling half to removably clamp said peg in said coupling.
  • a warp knitting machine according to claim 1, bearing means for supporting said coupling, and removable means for attaching said bearing to the machine.
