Abstract
Helicoidally splined (3) roller for cutting one or several superimposed ribbons of synthetic fibre into constant or vari-lengthed sections is designed for use with a counter-thrusting roller at a spinning mill: and has an elastic infill (4) between splines to enhance cut. Rollers are uniform metal cylinders (2) with axially projecting stub shafts (1) and splines (3) of triangular cross section projecting above the cylindrical surface to form cutting edges. The pitch of splines can be varied or uniform, the ratio of cylinder length (a) to dia. (b) is between 2.23 and 6 the former (a) being approx 340 mm. Spline pitch can be left or right hand or half of the cutter can be left hand with the rest right hand etc.
