Unwind Application with SimpLok™ Module


SimpLok™ shaft holder modules are the perfect answer where an unwind or rewind station is required on existing machine framework. These modules work well where easy installation of better braking and tension control systems are desired. Heavy duty steel construction provides for years of reliable operation. Ball bearings are typically supplied to ensure the proper foundation for accurate tension control.

Designs may include CAC's air operated tension brake and CAC's COR-LOK® air shafts for a complete unwind or rewind module solution. These modules may also be supplied with other brakes and / or air shafts at your request.

Tech tip: Manual Lateral Adjustment Can Help with Unwind Setup and Machine Operation
