    摘要: This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.
