Definitions

  • This invention relates to cop winding machines in which the dofllng of cops and/or the donning of cop tubes is effected in respect of a plurality of spindles simultaneously, sometimes all the spindles on one side of the machine. For this purpose various manual operations have heretofore been required, requiring a considerable amount of labour, particularly. where the cops carry only a comparatively small amount of yarn, so that frequent changes of cops are required.
  • the object of the present invention is to avoid manual operation, and to eifect all the requisite movements automatically, irrespective of whether the winding machine has full length spindles for v the cop tubes or whether the tubes are held between pegs engaging only into their ends.
  • the invention includes also means whereby the dotted cops remain in engagement with holders which give them a movement for breaking the yarn, and adjustable means whereby the thread guides are uncoupled from their actuating mechanism when the cops have been full wound, so that the thread guides return automatically to their initial positions, the rapid return movement of the thread guides to their initial positionvserving automatically to'initiate movement of the device for doiiing or releasing the cops and donning the .emptyftubes.
  • a fly wheel.or the like may be provided at a suitable part of the drive so that the spindles continue to revolve after the drive hasbeen declutched, causing the loose endof the yarn to become-attached to the spindles.
  • Thenumber of revolutions made by the spindles under the influence oi thefly wheel, and consequently the length of the thread wound on the spindles may be regulated by means of a brake device.
  • Figs. 1 and 2 are diagrammatic views of one form of. construction, Fig. 1 being a sectional view along one or the spindle stations with certain parts in elevation, and Fig. 2, a front view of the machine.
  • Fig. 3 is a plan view of the cop and tube carrier used in this example, with part of mechanism for actuating it.
  • Figs. 4 to 8 show an example in which the tubes are held between pegs, the machine havingno full length spindles.
