  • the fiber bundle F is fed from the second rollers 111a and 111b toward the third rollers 112a and 112b and is drafted while passing through these rollers.
  • Apron bands are required to have a certain level of flexibility because they are brought into contact with fiber bundles or fibers. For this reason, conventionally, rubber apron bands are used (Patent Literature 1).
  • the inner side of a rubber apron band is required to have slidability along a tensor bar. Accordingly, in general, the surface of a rubber apron band is acid treated.
  • a proposal is made to provide a smoothing cover layer having a low friction coefficient that is attached to the inner side of an apron band with the use of an adhesive (Patent Literature 2).
  • Japanese Publication No. JP H08 188927 A in the name of ARMSTRONG WORLD INDUSTRIES INCORPORATED, describes a textile fiber processing unit and a composition for textile surface layer of the unit that is designed for fiber handling and abrasion resistance.
