This Unwind Stand was built to replace a shafted unit with a smaller diameter and less weight capacity. Built for cleanroom use, this stand was designed to make loading large rolls of material easier for the operator. The shaftless design eliminates the need for shafting space and speeds up the roll changeover time.
