Vecoplan LLC of High Point, N.C., received a U.S. patent Jan. 4 for its FF series of rotary shredders, designed for film and fiber.
Vecoplan said the FF machines are the first shredders capable of one-pass size reduction of film and synthetic fibers to a desired consistency. Those materials tend to wrap around cutting rotors.
The patents cover the “SureCut” cutting technology, which uses a double row of primary cutters augmented by auxiliary nip cutters that prevent wrapping, a wedge bed knife, a close-tolerance robot and a reinforced screen.
