Components of the system

Index

Essentially, these systems consist of (Fig. 54):

  • a conveyor belt (T) equipped with discs to hold tubes (or cops), or a conveying mechanism with support discs arranged one behind the other on narrow rails for pushing the discs along the machine. In both cases the discs serve to convey the tubes prior to doffing and the cops after doffing;
  • a doffing rail (B), also extending along the entire length of the machine, equipped with pegs (Z) which engage with the tubes (Zinser) or collars to grip the outside of the tubes and cops;
  • a system of lifting levers (G), usually in the form of tongs, to raise and lower the rail and swivel it in and out;
  • a tube preparation and creeling device at the end of the machine, and
  • a cop storage device, also at the end of the machine, or a cop transfer unit to a directly connected winder.
