Definitions

  • the invention relates to a device for unwinding a linear textile material, in particular elastic, representing a continuous component of a component yarn in a textile spinning machine for a component yarn production, where for each operating unit of the spinning machine it consists of a pair of unwinding pivoted rollers composed of a drive and a driven unwinding roller for storage of an unreeled bobbin with a linear textile material.
  • Component yarns composed of spun-out component made of singled-out fibres and a continuous component composed of a linear non-elastic textile material or a linear textile material containing an elastic elastomer are produced on rotor spinning machines.
  • Production of an elastic component yarn requires among others to keep a certain stress in a linear textile material in the entry into a spinning rotor, particularly in an elastic material. This can be reached by a method of unwinding it from its bobbin, where the delivery speed of an elastic linear material into the spinning rotor and accordingly a circumferential speed of unwinding cylinders or a cylinder is lower than draw-off speed of a component yarn out of the spinning rotor.
  • CZ PV 2001-33 solves mentioned problems using a through unwinding shaft or shafts positioned along the rotor spinning machine.
  • Drive unwinding shaft is pivoted and it is coupled with a central control drive with adjustable ratio between revolutions of unwinding shaft of the unwinding mechanism of a linear textile material and revolutions of draw-off device shaft of a component yarn from the spinning rotor.

  • the device according to the invention allows in each operating unit of the textile spinning machine unwinding of a linear textile material, in particular elastic linear textile material, in a speed demanded by properties of produced component yarn and/or processed linear textile material. Important is in particular the possibility to reach optimal ratio of unrolled linear textile material speed and the speed of component yarn drawn-off from the spinning rotor.
