New sheet winding systems from Processing Technologies International, LLC (PTi), Aurora Ill., comprise cantilever, A-frame, turret, and automatic designs. These winders are supported by a line of sheet accumulators featuring fully integrated pneumatic tension control. The company said it developed these products in response to sheet processors’ demand for turnkey production solutions. Fully automated features include cut-and-transfer, shaft extraction, roll unloading/core loading, and roll-weight measurement and recording. Several of the winders are capable of differential shaft winding, allowing for multiple webs on a single shaft. Although initially developed solely to support its sheet extrusion systems, PTi is also offering the winders/accumulators on a stand-alone basis.
