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; and elements for generating magnetic fields for controlling driving and/or restraining forces applied to the metal band or the metal sheet.
Claims6
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 the 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 acting on the one of a metal band and a metal sheet for applying thereto at least one of a driving force and a restraining force.
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 displaceable;
- and an eddy-current system for generating eddy-current acting on one of a metal band and a metal sheet for producing a linear tension therein.
