Definitions

  • the invention relates to a bobbin or sleeve carrier for a bobbin and tube transport system on a textile machine, wherein the bobbin or sleeve carrier comprises a pin arranged on a base for receiving an empty sleeve or a bobbin, and the base body includes a carrier base, with which the Coil or sleeve carrier directly or indirectly slidably rests on the support surface of a conveyor track of the transport system.
  • Coil or sleeve transport systems for the removal of the cops or the coils of and for feeding empty tubes to textile machines, such as spinning machines or winders, are well known.
  • the coil or sleeve carriers are normally called peg trays, also called peg trays, which are slidably guided on conveyor tracks designed as carrier rails. Ie. the peg slides slide during their movement towards the work stations or away from the work stations on the mounting rails.
  • the mounting rails take on at least a portion of the weight of the loaded with coils or sleeves peg slide.
