  • WARP-THREAD STAND FOR TEXTILE DRAWING-IN MACHINES Filed May 15, 1964 United States Patent 3,280,442 WARP-THREAD STAND FOR TEXTILE DRAWING-IN MACHINES Hugo Meierhofer, Uster, Switzerland, assignor to Zellweger Ltd., Uster, Switzerland, a corporation of Switzerland p Filed May 13, 1964, Ser. No. 367,123 Claims priority, application Switzerland, May 20, 1963, 6,440/ 63 7 Claims. (Cl. 28-44)
  • the invention relates to a warp-thread stand for textile drawing-in machines.
  • a known warp drawing-in machine the warps are put over a movable frame which can be placed by the machine relative to the machine in such a manner that the warp threads come successively within the range of a thread-separating mechanism whereafter the threads are individually separated and drawn into heddles.
  • Frames or stands of this type are designed to receive a warp beam or two warp beams, when drawing in doublebeamed warps, since the warp beam or beams must move along with the frame during the drawing-in operation. Although such frames can be movable they cannot be moved through the weaving rooms because of their size.
  • the warp beam must be placed on the stand by some means before drawing-in and must be removed from the frame together with the drawn-in harness, after the drawing-in has been completed.
  • Trucks which can be driven directly to the loom are used to transport the warp beam with the drawn-in harness.
  • the transfer is complicated and time-consuming since the warp beams have a considerable weight and since the drawn-in warp must be handled carefully.
  • An object of the invention is to obviate the drawbacks of conventional warp drawing-in machines.
  • a warp-thread stand or frame for textile drawing-in machines comprising a first component for accommodating the section of at least one warp to be drawn in and a second, traveling component for accommodating at least one warp beam, the two components being capable of being separated or being connected to each other in such a manner that the first component is carried along by the second component when the second component is moved.
  • FIG. 1 shows an elevation of a warp-thread draw-in frame according to the invention.
  • FIG. 2 is a part-sectional side View of the frame shown in FIG. 1, the two components of the frame being separated from each other.
  • FIG. 3 is a part-sectional plan view of the frame.
  • the illustrated frame comprises a first component intended to accommodate the section of the warp which is to be put in.
  • This first component comprises a U- shaped bottom portion 1 which travels on four swivel casters 2.
  • Two columns 3 whose upper ends carry bearing pins 6, are mounted on the lower portion 1.
  • Lateral supports 4 are rotatably mounted on the pins 6.
  • These lateral supports 4 are interconnected by warp clamping rods 5 and constitute a frame which can be positioned horizontally for fixing the warp and then brought into a vertical position for drawing in the warp threads.
  • the frame is maintained in the aforesaid positions by locking devices, not shown.
  • a second movable component serving to accommodate the warp beam comprises two side pieces 7, each of which is supported by two swivel casters 8.
  • the side pieces 7 are connected by two telescoping tubes 9 and 10, the tubes 9 being rigidly connected to one side piece 7 and the tubes 10 being connected in a similar manner to the other side piece 7.
  • Each side piece 7 is provided with a bracket 11 which has a bore at its end to receive a coupling pin 12.
  • the bottom part 1 has bores 13 into which, when registered with the bores of the brackets 11, the coupling pins 12 extend.
  • the tubes 9 and 10 also serve as a support for the warp beam.
  • Each side piece 7 has a column 14 with an aperture at its upper end for accommodating a rod 15.
  • the rods 15 receive and support the drawn-in harness frames and carry holders 16 for the droppers of the warp threads.
  • Brake blocks 17 are longitudinally displaceably mounted on the columns 14 and can be secured in a desired position by clamping screws 18.
  • the first component which is intended to accommodate that section of the warp which is to be drawn in remains close to the drawing-in machine, while the second component is used to fetch the warp beam.
  • the tubes 9 and 10 are displaced with respect to each other in such a manner that the second component has a length corresponding to the length of the warp beam and that the holes in the brackets 11 are spaced by a distance which suits the spacing of the holes 13 on the bottom portion of the other first component.
  • a warp beam 19 is then placed on the tubes 9 and 10 and travels with the second component to the first component.
  • a locking device prevents the tubes 9 or 10 from sliding into each other during such travel.
  • the two components of the frame are then brought into the position relative to each other shown in FIG. 3 and linked together by the coupling pins 12.
  • a suitable portion of the warp 20 is then unwound from the beam 19 and stretched, in known manner, over the frame formed by the lateral pieces 4 and the clamping rods 5.
  • the brake block 17 on each side piece 7 is pressed against discs 21 of the warp beam 19 and maintained in this position by means of the clamping screws 18.
  • the stand as a whole is moved away from the drawing-in machine, whereafter the drawn-in shafts can be slid upon the rods 15. If, on the drawing-in machine, also droppers have been drawn in simultaneously, the dropper carrier rails must be placed into the holders 16 prior to moving the shafts onto the rods 15.
  • the warp beam with the drawn-in harness can then be moved either directly to the loom or into the store or drawn-in warp, rotation of the warp beam being prevented by the brake blocks 17.
  • a stand for warp drawing-in machines comprising:
  • a first component for accommodating the section of at least one warp to be drawn in
  • each of said components having means affording independent movement of said components
  • a stand for warp drawing-in machines comprising:
  • a first component for accommodating the section of at least one warp to be drawn in including a bottom portion supporting a frame structure carrying a plurality of warp clamping rods,
  • a second component for accommodating at least one warp beam including a pair of side pieces supporting means for carrying at least one warp beam,
  • said side pieces each being provided with fastening means secured to one end thereof, and
  • said first component further includes a pair of columns mounted on said bottom portion, said frame structure being pivotally supported on said columns.
  • a stand for warp-drawing in machines comprising a first component for accommodating the section of at least one warp to be drawn in,
  • a second component for accommodating at least one warp beam
  • each of said components having means atfording independent movement of said components
  • said second component being provided with supports for drawn-in harness frames, and with brake means for preventing rotation of the warp beam.
  • a stand for warp-drawing in machines comprising a first component for accommodating the section of at least one warp to be drawn in,
  • a second component for accommodating at least one warp beam
  • each of said components having means affording independent movement of said components
  • said second component comprising two side pices provided with said means affording movement of the second component, and means interconnecting said side pieces, said means including means for varying the distance between said side pieces.
