Definitions

  • This invention relates to a novel sliver handling system in fore-spinning or preparatory spinning process, and more particularly to a sliver handling system for automatically and continually supplyirn slivers delivered from one drawing or drafting stage to the next drawing or drafting stage with the necessary blending or doubling effect simultaneously accomplished.
  • the present invention provides a novel system for automatically and continually transferring and supplying slivers from any drawing frame to the next drawing frame while maintaining the doubling or blending effect without requiring any manual operation in sharp contrast to the conventional system.
  • slivers are automatically and continually transferred and delivered from one drawing frame to another drawing frame with the necessary blending or doubling effect simultaneously accomplished, by connecting one drawing frame to another or the next drawing frame in a novel manner whereby not only the exchange, transfer and positioning of cans or containers but also feeding of slivers that have been heretofore carried out manually by workers are eifected automatically and continually without sacrificing the effect of blending or doubling.
  • a whole group of containers are intermittently moved as a unit by a suitable drive mechanism so that when one of the containers becomes substantially full of sliver the next or following empty container is moved into the sliver charging position vacated by the preceding container so as to permit the sliver to be continuously delivered to said empty container.
  • the slivers for instance, six slivers
  • a given number of already charged containers six containers
  • the sliver content in the containers is gradually less from the newly charged one toward the foremost one. More particularly, the amount of sliver in one of such containers is always larger than the amount of sliver in the preceding container.
  • the intermittent drive mechanism mentioned above is so controlled as to be actuated substantially at the same time when the foremost one or oldest one (that is, the containers which holds the least amount of sliver at the moment) among the containers whose slivers are being charged into the next drawing frame is completely emptied.
  • One object of the present invention is to eliminate the manual operation which has been heretofore inevitable between two adjacent drawing frames by interconnecting them in a novel system without sacrificing the elfect of doubling or blending.
  • Another object of the present invention is to provide a novel apparatus for accomplishing the aforementioned object.
  • An additional object of the present invention is to contribute toward the realization of automation in fore-spinning process.
