The Double E narrow web unwind/rewind station regulates the tension of narrow web material while providing quick roll changes and the flexibility of running multiple core sizes. Problems associated with poor tension control, such as core slippage and excessive dust, are eliminated resulting in a faster, cleaner and more efficient production process.
Features and Benefits
- Easily mounts to any section of the production line.

This type of pneumatic brake utilizes packed discs (steel + lining) with a piston thrust drive in order to obtain higher torque performances. A rotary joint is used for air feeding.
Magnetic particle brake (powder brake) provides precise, quick-response tension control for light tension applications (under 1 pli). The powder brake is a quiet alternative to friction brakes, and is ideal for clean environment situations. Low voltage (24V DC) operation presents no safety hazards and makes installation and use simple (no transformers are needed to convert from standard electrical supplies). The compact brake is available with an integral fan or radiator for heat dissipation.
For applications where there is no (pneumatic, electric or hydraulic) feeding type, brakes are proposed in manual execution, where the spring drive consists of a turning handwheel manually actuated by the operator.
Slipper clutches comprise of a series of steel plates that engage a hub and a succession of friction rings engage the housing. Pressure is applied to the plates and friction rings by adjusting a knob through a spring and pressure plate. This is ideal for manual operation for slow and low tension applications.
These compact motors are specifically designed for variable-speed drives in motion control applications. Ideally suited for precise control of rewind and unwind. Tension control systems are required.
