Abstract
The method and unit for braking a metal strip (1), running off a wind-out coiler (2.1) in the form of a coil (1.1) and running onto a wind-on coiler (2.2) again, are to guarantee that a surface of the metal strip remains undamaged and a full effective braking force is exerted on the metal strip (1) by means of an eddy current brake (3.1) with a rotating magnet system (3.2). The above is achieved, whereby the braking force is exerted on the metal strip (1) by means of an induced counter-torque against a support bearing (4) to one side in a non-contact manner, whereby the support bearing (4) may be embodied as a counter roller (4.1).
Claims19
A method for braking a metal strip, comprising:
- providing an unwinding reel and a winding-up reel;
- running the metal strip off from the unwinding reel as a coil;
- running the metal strip onto the winding-up reel;
- providing a braking assembly having an eddy-current brake having a rotating magnet system for generating a braking action on the metal strip and an abutment;
- wherein the eddy-current brake remains apart from the metal strip in a contactless fashion;
- running the metal strip through the braking system;
- supporting the metal strip with the abutment as the metal strip runs through the braking system;
- and
- generating an eddy-current with the rotating magnet system for causing a braking action against the metal strip.
A unit for braking a metal strip, comprising:
- an unwinding reel;
- a coil operably associated with the unwinding reel;
- a winding-up reel;
- and
- a braking assembly having:
- an eddy-current brake;
- and
- an abutment;
- wherein the metal strip passes between the eddy-current brake and the abutment;
- and
- wherein the metal strip comes into contact with the abutment and remains apart from the eddy-current brake in a contactless fashion.
