Abstract: An improvement is made to a die cutting press and to the method of die cutting in a press by providing two opposing and oppositely driven clamping bars which move together to clamp the die board and to accurately position the clamped die board at a predetermined location within the press. The press is operated to determine the adequacy of the cut produced by the die in sheet material fed into the press.

The die board can be removed from the press and then manipulated or modified to cure any imperfection in the cut. The modified die board is then reinserted into the press and accurately repositioned at the predetermined location within the press by driving the opposing clamping bars towards each other against the die board.

Abstract: According to the disclosed process, an endless fibrous material to be cut is wound in spiral form onto a rotatable cutter roll having radially outwardly oriented knives. A cutting force acts from the outside of the cutter roll radially inwardly, by way of a pressure roller contacting the wound material, for cutting, for example, synthetic fibers. In the process, at least two cutting forces are effective against the axis of the cutter roll, these forces being directed against each other. In the apparatus for conducting the process, two pressure rollers are articulated to each other by way of a double rocket arm. Consequently, the optimum cutting level, which will be different in individual cases, is automatically set. The effective cutting force for each roller is of equal strength.
