Definitions

  • the invention relates to a heald frame with shaft rods made of an aluminum profile and with side supports, wherein the side supports on the end faces of the shaft rod ends each engage with a projection in cavities of the aluminum profile and are anchored therein by means of screws.
  • a heald frame is described in DE-A-3017629.
  • the invention has for its object to form a heald frame with shaft rods made of an aluminum profile so that a secure connection of the side supports to the shaft rods and good power transmission from shaft drive to the shaft rods and the side supports is achieved.
  • the object is achieved with a heald frame of the type mentioned at the outset in that the projections of the side supports have the same thickness as the shaft rod at least in the region of the anchoring screws and protrude into suitable end-side recesses in the shaft rod and in that the anchoring screw has its head on one each on the narrow side of a shaft rod, the cheeks are placed on the outside and the other end is screwed into the threaded bore of a jaw inserted into a cavity of the shaft rod profile.
  • the projections of the side supports can expediently rest at least approximately over their entire circumference on the edges of the matching end recess of the associated shaft rod end.
  • the connecting projections of the side supports are thicker than in conventional heald frames, so that they allow the formation of larger through-bores for stronger anchoring screws.
  • the projections are no longer just on the side walls of the shaft rod hollow profile and on fastening jaws, but are supported by the system against the edges of the end recess formed in the shaft rod end over their entire circumference and thus tilt-proof on the shaft rod.
  • the jaws placed on the outside of the narrow side of the shaft rod allow a good distribution of the forces transmitted via an anchoring screw to the shaft rod.
  • the cheek placed on the outside can also be formed by a shaft drive piece, the anchoring screw serving at the same time for fastening this shaft drive piece.
  • the anchoring screw serving at the same time for fastening this shaft drive piece.
  • the tilt-proof seat of the projections of the side supports in the shaft rods can be increased by an extension of the projections, which has a smaller thickness than the shaft rod and fits into a cavity of the shaft rod profile. This extension creates additional force transmission surfaces on the inside of the shaft rod.
  • connection points of the side supports with the shaft rods of a heald frame designed according to the invention are explained in more detail with reference to the attached drawing.
  • the one side wall 12 is extended beyond a lower narrow side 16 of the shaft rod 10 to a holding part 17 which, according to FIGS. 2 and 3, can have larger cutouts 36.
  • shaft rods 10 form the upper and lower frame legs of the heald frame in a known manner and are also advantageously provided with profiled but narrower side supports 18 connected to each other.
  • FIG. 2 shows the lower right corner and FIG. 3 the upper right corner of a heald frame, where a side support 18 is in each case connected to a shaft rod 10.
  • the side support 18 is provided at both ends with a solid web-like lateral projection 19 and 20, which has the same thickness B as the shaft rod 10.
  • Both projections 19 and 20 also have an extension 21 and 22, which has a smaller thickness, which corresponds to the inside width of the cavity 14 of the shaft rods 10.
  • both the lower shaft rod 10 visible from FIG. 2, and the upper shaft shaft 10, shown in FIG.
  • the heald frame are provided with an end-side recess 23 and 24 which, except for the corners, conforms exactly to the shape the projections 19, 20 are adapted so that the projections 19 and 20 can be inserted without tilting into the recesses 23, 24 of the shaft rods 10 formed by milling, the extensions 21 and 22 being immersed in the adjoining cavity 14 of the shaft rods 10.
  • the projections 19 and 20 are thus supported almost over their entire circumference at the edges of the cutouts 23 and 24 and thus on the side walls 11 and 12 of the shaft rods 10.
  • the projection 20 (and in the same way also the lower projection 19 of the shaft rod 18) is provided with a through hole 25.
  • the through hole 25 serves to pass an anchoring screw 26 or 27.
  • the other end provided with a thread 27.2 of the anchoring screw 27 is screwed into a threaded bore of a second jaw 29, which is inserted into the cavity 15 of the shaft rod 10 and held there by means of a dowel pin 30, which is held by a transverse bore in the jaw 29 and with it aligned holes in the side walls 11 and 12 of the shaft rod 10 protrudes.
  • the anchoring screw 26 serves at the same time for fastening a shaft drive piece 31 placed on the upper narrow side 13 of the shaft rod, on which the shaft drive device acts, but whose known structure is of no further interest.
  • the base 31.1 of this shaft drive piece 31 here forms the jaws, against which the head 26.1 of the anchoring screw 26 rests, the threaded other end 26.2 of which can be screwed into the threaded bore of a second jaw 32 which is inserted into the cavity 15 of the shaft rod. While the jaw 28 shown in FIG.
  • the side supports 18 can be easily and quickly released from the shaft rods 10.
  • the jaws 29 and 32 serving to anchor the clamping screws 26 and 27 with their threaded bores are expediently made of steel. Anchoring of the screws in the relatively soft aluminum material of the shaft ends 10 is thus avoided.
  • the jaws can be easily replaced if the threads of their holes are damaged.
