Abstract
An apparatus and method are provided for guiding steel bands of a continuously operating press about a longitudinal axis during operation of the press without overstretching one side of the steel bands. First and second bands are guided, via driving drums and return drums, around a pressing ram and a pressing table, respectively. The steel bands are supported, with an adjustable pressing gap, on a plurality of co-rotating steel rods which are guided, with their axes of rotation extending transversely to the direction of travel of the bands, against abutment lugs of the table and the pressing ram. The axis of at least one of the drums is altered in a first direction through an angle .beta.. The altering step comprises the steps of temporarily relieving pressure in short-stroke pressure cylinders which are located on one longitudinal side of a high-pressure region of the press, and then applying a pressure which opposes the pressure imposed by the pressure cylinders and overcomes the pressures imposed by those of the pressure cylinders which are located on the one longitudinal side, thus adjusting the position of the one longitudinal side and altering the axis.
