摘要

The drive roller for the winding conical bobbin, with a constant yarn feed, is composed of at least two rotating sections at different speeds, with a groove between the sections open at the top. The ring-shaped end surfaces (11, 21, 22, 32), forming at least part of the groove flanks between the adjacent rotating sections (1-3) of the drive roller are fitted with lateral grooves (111, 211, 221, 321).
