ABSTRACT:
The invention relates to a process for the guiding, positioning and motion control of bands of material and a set of guide rolls for carrying out the invention. A pivotal frame rotatable and pivotal about an imaginary vertical axis with regard to a stationary basic frame by means of a pivotal cylinder is supported on said stationary basic frame. On the pivotal frame, two lower rolls with horizontal axes are spacially supported. An upper roll with horizontal axis rotatably supported on a superposed frame is descendable into said space. The superposed frame is articulated to the pivotal frame on one end by means of uprights and on the other end by means of contact pressure cylinders. It is the object of the invention to use said set of guide rolls also as a set of driving or braking rolls in order to achieve an effective guidance and control of the band also during the entrance and exiting stage. This is achieved by forming the uprights as double-armed levers pivotal by means of pivotal cylinders in their centers about a horizontal axis arranged on the pivotal frame.
