Automatic motions are fitted on thedrawing rollers of rovings and spinning frames to move the drawingrollers on end; this prevents the drawing rollers getting groovedat one part of the roller, and of course makes the drawing rollerslast out much longer. 32 Flutes in 2 Roller \ 34363840486466 2i H 34 Preparing Drawing Rollers.
