ABSTRACT:
The invention relates to a device for working plate-shaped material, the device being provided with a frame and a pair of cooperating elongated working members. One of these working members has a stationary arrangement in the frame, while the other is movable in the frame, transversely to its longitudinal direction, towards and away from the stationary working member. Both the frame and the movable member are each provided with a plurality of rollers which, when seen in the longitudinal direction of the working members, are arranged one behind the other. An endless belt is passed over the series of rollers. The belt is fixed at one end and is at it other end connected with a driving means, by which the belt can be moved in its longitudinal direction to draw the movable member and frame closer together, or to permit them to move apart under the influence of an external opposing force.
