SENDING OF PRELIMINARY ROVING IN FINE SPINNING FRAME AND DEVICE THEREFOR

摘要

PURPOSE:To smoothly carry out roving changing operation and doffing operation of roving process, by sending a transportation member having hung the same number of preliminary roving packages as one creel line in a specific state to a preliminary roving package rail. CONSTITUTION:Preliminary roving package rails 2 are extended along a creel at both sides of a machine bed 1 of a fine spinning frame having hung roving packages S on the creel in two longitudinal lines and the rails 2 are connected through a branching part 3 a to a main transportation rail 3 continued to a roving process. A transportation member 4 having hung the same number of preliminary roving packages F at given intervals as one creel line is sent in such a way that the stopping position of the transportation member is shifted from that of the last roving changing operation by one pitch of the roving package line of the creel and arrangement position of preliminary roving packages is changed corresponding to roving doffing of odd-numbers lines or even-numbered lines.
