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.
