Abstract
In a cutting machine for a synthetic filament tow the filament tow 3 before passing between the cutting rolls 1/2 is traversed laterally to and fro. The present invention teaches, in which manner the traversing movement of the tow guide 5, moved to and fro using a grooved drum 10, is to be effected for obtaining a linear, i.e. optimum, fibre length diagram of the cut fibres. In particular, the mathematic formula for the shape of the guide groove 9, as unrolled in a plane, of the grooved drum 10 is given.
