Definitions

  • a yarn called a "core” 1 flows from a feeder 2, goes into the axial hollow of a rotating spindle 3, reaches a false twist spindle 4 and is wound on a spool 5 which has the same peripheral speed as feeder 2.
  • Another effect yarn (or several yarns) 6 flows (flow) from a feeder 7 (or from several feeders), is guided through a device that promotes the union of the yarns called "slub" 8 and meets yarn 1, winding around it by the (false) twist effect generated by spindle 4 on yarn 1 itself.
  • Fig. 2 indicates a variant, still of known type, in which rotating spindle 3 and that of false twist 4 are solid on the same axis of spindle 3, i.e., 4 rotates with 3. All the spindles like 3 mounted on the machine are driven by a single belt 11 which receives the movement from a single motor (not shown).
  • Fig. 3 represents a further known variant in which the unit of spindles 3 and 4 is mechanically disconnected, i.e., all spindles 3 are driven by a single belt 11 and all spindles 4 are driven by another single belt 12: the speed of 11 and 12 therefore can be different, which makes it possible to achieve a greater number of effects.
  • Fig. 4 indicates another known variant in which each individual unit made up of 3 and 4 can be driven by an auxiliary motor 18, by which the speeds and 3 and 4 can be different as in the case of fig. 3.
  • pulley 14 is solid with the hollow shaft of 3, 15 and 16 rotate on countershaft 13 and 17 is solid with false twist spindle 4.
  • the whole unit is driven by a single belt 15 which drives hollow rotating spindle 3, then the rotary movement of false twist spindle 4 originates from that of hollow rotating spindle 3.
  • countershaft 13 and interchangeable pulleys 14, 15, 16, 17 can be replaced by equivalent known means without going outside the scope of protection of the invention.
