Definitions

  • the invention relates to a heald frame with releasable corner connections between the side supports and the shaft rods, which form essentially rectangular hollow bodies, in the cavity of which a projection formed on the side support engages in a pin-like manner with each corner connection and is clamped by means of a screw.
  • Heald frames with detachable corner connections of this type are known, for example, from DE 37 02 524 AI and have the advantage that they can be released very stably and quickly if the heald frame has to be dismantled and reassembled in the weaving operation.
  • the heald frames of the heald frames today mostly consist of profiles made of different materials such as aluminum, fiber-reinforced plastic or steel, and the fastening of the side support by means of a clamping screw held in the profile and acting on a pin-like projection arranged on the side support is a proven solution because of the wall thickness of the profiles used is sufficiently strong for clamping.
  • the invention was therefore based on the object, also for such a shaft rod made of steel and with thin side walls to find a solution to use the proven corner connection with a clamping screw.
  • the heald frame has the features according to claim 1.
  • Preferred embodiments have the features according to the dependent claims.
  • the insert preferably forms a rectangular housing consisting of two blocks parallel to the longitudinal straps of the shaft rod and two reinforcement walls connected to them, one block of which has a threaded bore for receiving the clamping screw, which presses the projection of the side support against the other block of the insert.
  • the reinforcing walls of the housing-shaped insert are at least partially firmly connected to the thin side walls of the shaft rod, preferably welded to one another, the forces occurring in weaving operation and to be transmitted from the side support into the shaft rod are directed as tensile forces onto the thin shaft rod side walls.
  • the thin side walls of the shaft rod that are firmly or partially connected to the reinforcing walls of the insert cannot bulge, which would be the case without the firmly connected insert.
  • the upper and lower longitudinal parts of the shaft rod are technically referred to as so-called straps and the thin side walls as so-called shear fields, which can absorb a very high load if one achieves that remain perfectly flat or cannot bulge, which is achieved by the measures according to the invention.
  • the thin side walls of the shaft rod, which are now subjected to tension, are thus able to distribute the large forces occurring evenly over the longitudinal straps of the shaft rod.
  • a horizontally extending projection 2 is formed, which is plug-like inserted into the hollow space 3 of the shaft rod 4 visible in FIG. 1 b to produce a corner connection and is clamped by means of a clamping screw 5.
  • the principle of this known corner connection is suitable for a shaft rod consisting of a light metal hollow profile.
  • the shaft rod 4 shown in FIG. 1b consists of interconnected steel parts, namely one upper longitudinal belt 6, an angled lower longitudinal belt 7, which carries the heddle support rail 8 and made of very thin side walls 9 and 10 fastened to the two longitudinal belts 6 and 7. These parts are preferably connected to one another by means of laser welding.
  • the cavity of the shaft rod is filled with a core preferably made of foamed material, which is not shown in the drawing and with which the very thin side walls with a material thickness of 0.5 mm or below are glued so that they remain level.
  • an insert 11 is arranged at the end of the shaft rod 4.
  • 2a consists of an upper block 12, which extends parallel to the longitudinal belt 6, and a lower block 13, which extends parallel to the longitudinal belt 7, and two reinforcing walls 14 and 15, which are approximately 3-6 times thicker Have wall thickness than the shaft rod side walls 9 and 10.
  • the blocks 12 and 13 and the two reinforcement walls 14 and 15 are joined together, for example by means of spot welding, to form a rectangular housing according to FIG. 2b.
  • the pin-like projection 2 of the side support 1 then fits into the cavity 3 present in this insert 11 from the side.
  • the upper block 12 has a threaded bore 16 for the clamping screw 5.
  • the clamping is therefore only in use 11, the clamping screw acting from the block 12 on the projection 2 of the side support and pressing it against the lower block 13.
  • the reinforcement walls 14 and 15 are firmly connected to the thin side walls 9 and 10 of the shaft rod 4, at least partially or even over the entire surface, preferably by means of welding, which is not shown in the drawing.
  • the thin side wall plate is expediently connected to the reinforcing walls of the insert by means of laser welding, along welding lines arranged along the surface.
  • laser welding allows the thin sheets and the belts to be connected in such a way that the desired effect of the invention comes to fruition.
  • the parts 11 can also be connected by rivets or screws for the production of the insert 11.
  • the firm connection between the thin side walls 9 and 10 of the shaft rod and the reinforcement walls 14 and 15 of the insert 11 can also be made by gluing, in particular if parts of the entire arrangement consist of fiber-reinforced plastic.
  • a modified embodiment shown in FIGS. 3a-4b differs from the previously described only in that the somewhat longer reinforcement walls 14 and 15 of the insert 11 extend to the longitudinal straps 6 and 7 of the shaft rod 4 and are firmly connected to them .
  • the insert 11 shown in FIG. 4b in this case points parallel and inward from the end edges of the reinforcement walls 14 and 15 with them Forming a housing firmly connected blocks 12 and 13 and the edge regions 14a and 15a of the reinforcing walls projecting beyond these blocks are firmly connected to the longitudinal belts 6 and 7 of the shaft rod, for example by means of a weld seam extending over the entire width of the reinforcing wall.
  • the thin side walls 9 and 10 of the shaft rod 4 have cutouts 18 and 19 in the size of these connecting edge regions 14a and 15 at the upper and lower edges. Otherwise, the thin side walls 9 and 10 of the shaft rod 4 are fixedly connected to the reinforcing walls 14 and 15 of the insert 11, preferably welded, in the same way as in the first exemplary embodiment.
