Definitions

  • a carrier or support for thread bobbins having a spindle provided with a resiliently supported abutment. The abutment supports one or more bobbins on the spindle at the same height regardless of the number of bobbins supported.
  • the present invention pertains to apparatus for the transport and storage of weft thread bobbins of the type which remain outside the shed during weaving and which are customarily employed in gripper shuttle looms.
  • weft thread bobbin rack or the like on the picking side of the loom which contains two bobbins for each type or color of weft thread employed, the weft thread being pulled off the free end of these bobbins.
  • the tail end of the thread on one bobbin is connected to the head end of the thread on the other.
  • the invention provides a light and readily handled device by means of which transfer of the weft thread from the Winding machines to the looms can be efficiently carried out, and which surmounts the disadvantages above referred to.
  • a spindle which is held or suspended upright in a suitable carrier and which has a support for the bobbins which is movable lengthwise of the spindle, this support being elastically stressed against the bobbins so as to permit the carrying of a number of bobbins on the spindle.
  • the elastic means are so stressed by the action of even 3,472,466 Patented Oct. 14, 1969 one of the bobbins that this support is pressed down by approximately the height of one bobbin for each bobbin loaded onto it.
  • the support rises on the spindle by the same distance. Consequently, the uppermost of the spools on the spindle is always at substantially the same level close to the top of the spindle.
  • the length of the spindle is advantageously so made that bobbins can be put onto and removed from it at a convenient position for the operators, for example at chest height for the operator.
  • the elastic means above referred to takes the form of a rubber cord or filament which is fastened to the upper end of the spindle and to the movable bobbin support. There is a substantially constant ratio between the stretching of such a rubber cord and the weight which it carries.
  • Other elastic media such as tension springs may be used instead.
  • a carrier is provided for a spindle or spindles to be inserted therein.
  • This carrier may form part of a wagon or truck which can take a number of spindles and which can be moved down the aisles between the looms.
  • the apparatus of the invention may include further a stationary carrier for a spindle to be inserted therein, this carrier constituting a part of a bobbin replacement store.
  • This carrier can, for example, be constructed to accept four spindles and is located adjacent to the warp beam of the loom near the loom rack for the bobbins from which the warp thread is drawn by the shuttles.
  • the carrier is arranged for the suspension of a spindle therein.
  • This carrier may constitute part of a transport device which is to be hung from an overhead pulley and by means of which the spindles can be delivered to various looms and inserted in a replacement rack.
