Overview
The caliper brake is a common type of pneumatic brake. Air pressure presses the friction pads in the caliper body against the rotating disc from both sides, and friction generates the braking torque. The torque is adjusted by changing the pressure, which makes tension easier to control on unwind stands. Its compact design allows it to fit into limited space on the machine.
Features
- Braking torque adjustable by air pressure
- Compact design clamping the disc from both sides
- Several calipers can act on one disc, depending on the application
- Replaceable friction pads
Applications
It is used on unwind stands to apply braking torque to the roll and create web tension. When the air pressure is set by a proportional valve linked to a tension controller, braking torque can be reduced automatically as the roll diameter decreases. Slitting, printing, laminating and paper machines are typical examples.
