Abstract
A device for drawing or braking metal bands or metal sheets and including two oppositely arranged endless revolving chain systems with a gap therebetween through which a metal band or a metal sheet is displaced and including carriage-like roller blocks for effecting one of clamping and driving the one of a metal band and a metal sheet, an elastic lining for covering the roller blocks; a plurality of shaping and filler pieces for controlling tension applied to the elastic lining; and elements for generating magnetic fields for controlling driving and/or restraining forces applied to the metal band or the metal sheet.
Claims2
A device for effecting one of drawing and braking one of metal bands and metal sheets, the device comprising two oppositely arranged endless revolving chain systems forming a gap there between, in which one of a metal band and metal sheet is displaced, and including carriage-like roller blocks for effecting one of clamping and driving the one of a metal band and a metal sheet;
- elastic lining means for covering the roller blocks;
- a plurality of supporting plates acting on the elastic lining means for controlling tension applied to the elastic lining means;
- and means for generating magnetic fields for a controlling at least one of driving and restraining forces applied to the one of a metal band and a metal sheet, wherein the magnetic fields generating means comprising magnet coils attached to the roller blocks.
