Abstract
A doffing carriage is mobile at the level of the flyer support bed of a roving frame, and carries cop and empty tube gripping elements which are orientatable between a vertical position and an oblique position. A peg conveyor loaded with empty tubes in a reverse zig-zag arrangement to that of the cop rotators is disposed at the level of a footboard. The cops, lowered on to an orientatable cop carrier, are gripped by the gripping elements in an oblique position, raised, disposed vertically and deposited on to the free pegs of the conveyor, proceeding from one end of the roving frame to the other. After moving the conveyor through one step, the gripping elements deposit the empty tubes on to the cop rotators by proceeding in the reverse direction. The same carriage loads the empty tubes on to the conveyor and unloads the cops from it at one end of the roving frame, while this latter is in operation.
