ABSTRACT:
A creel device for a drawing frame, having a drive train for lifting rollers for taking out slivers from respective cans. In one embodiment, the cans are divided into two groups each constructed at consecutively located cans. The drive train is divided into two sections for driving respective lifting rollers for respective groups of cans. The basic section is for driving lifting rollers for the group adjacent the draft part, and the second section is for driving lifting rollers from the group remote from the drafting part. The first section is connected to a rotating movement source in the machine frame, while the second section is connected to a variable speed motor. The speed of the variable motor is set so that a predetermined ratio is obtained between the rotational speed of the lifting rollers of the second group and the rotational speed of the lifting rollers of the first group, so that a substantially equal tension is obtained between the sliver taken out from the can adjacent the draft part in the first group and the sliver taken out from the can adjacent the draft part in the second group.
