ABSTRACT:
An apparatus for cutting rod or strand-like products comprised of a rotary holder positioned adjacent the outlet end of a tube from which a water jet is discharged and in which the rod or strand-like products are entrained. The rotary holder includes a plurality of individually actuatable cutting blades movable between cutting and non-cutting positions. An optical scanner determines the presence of dark or discolored areas on the products and generates a signal timed to actuate a sufficient number of cutting blades which will cut through the product as it emerges from the tube and separate the discolored area from the acceptable areas. The cutting blades can be held inoperative by electromagnets and returned by a cam. Alternatively, the blades can include a deflection member and jet nozzles can be employed to pivot the blades in and out of the cutting position.
