摘要

PURPOSE:To carry out the change of empty or small build-up bobbins with full bobbins with ease and rapidity, by changing the roll build-up diameter of roving bobbins to be hung in the front row in a creel in starting the spinning from that of the bobbins in the rear row. CONSTITUTION:The roll build-up diameter of roving bobbins to be hung in the front row in a creel is changed from that of the bobbins in the rear row to provide always small build-up bobbins in either one of the front and the rear rows and medium build-up bobbins in the other row at that time. Empty or small build-up bobbins to be changed with full bobbins are always placed in the front row of the creel by using a roving replacing machine 10 for changing bobbins in the front row with those in the rear row and a roving changing maching 64 for changing empty bobbins with reserve bobbins.
