Abstract
The tension of a web or strand being unwound from or wound into a ball or roll is controlled in an advantageous manner. The apparatus is particularly related to a creel for feeding out slivers of wool from a plurality of balls of sliver. The apparatus comprises first and second parallel rotatable shafts, the first driven at a relatively fast speed and the second at a relatively slow speed, and first and second rollers coaxially disposed on the shafts and rotatably mounted with them, the roller for receiving a strand wound thereon. The rollers are coupled so that they rotate at substantially the same speed. A clutch, responsive to a control signal, is provided for selectively coupling a first roller to the first shaft to rotate the rollers at a fast speed, or to couple the second roller to the second shaft to rotate the rollers at a slow speed. A switch, responsive to tension in the strand, controls generation of the control signal to the clutch.
