Definitions

  • ABSTRACT Mechanism for controlling the tension of a strand from a spool of strand material on a strand fabricating machine having a work center" toward which a tensioned strand is incrementally released.
  • the spool is carried by a spool holder having a base housing a spool release mechanism.
  • the mechanism of the invention provides an actuator means for releasing the spool for rotation when the strand tension reaches a desired value.
  • Strand fabricating machines utilizing the present invention have sets of spool carriers which are moved along circular paths in opposite directions relative to the work center of the machine toward which tensioned strands from the spools are incrementally released.
  • the tensioned strands may be interlaced, woven, braided or spiralled as to each other or around a core member.
  • the disadvantages thereof include being subject to excessive wear, either a low speed of operation or requiring of continual adjustment, in some forms, having a high noise level of operation, and in all forms, being suscep- It is an object of the present invention to provide an improved mechanism for controlling the tension of strands from spools of strand material on a strand fabricating machine having a work center" toward which a tensioned strand is incrementally released.
  • a strand tension-controlling and spool release actuator mechanism is used with a spool holder having a base adapted for mounting on a strand fabricating machine, a spindle extending from the base for carrying a spool of strand material, and a deck projecting laterally of the spindle.
  • the spindle may be fixed or rotationally mounted in'relation to the base.
  • the spool holder further has a spool release mechanism carried by the base whereby a spool will rotate against a frictional force which is released by selective movement of a control flange projecting laterally of the base and below the deck.
  • the mechanism according to the invention further has a support rod on the deck extending parallel to the spindle.
