摘要： The instant invention is a stuffer box crimper and a method for crimping. The stuffer box crimper according to instant invention includes a pair of nip rollers, a pair of doctor blades, and a stuffer box. The pair of doctor blades is adjacent to an exit end of the pair of nip rollers. The stuffer box includes a stuffer box channel adjacent to the pair of doctor blades, and the stuffer box channel includes a surface consisting of a hard material having a hardness of at least 60 Rc. The method of crimping according to instant invention includes the steps of (1) providing a stuffer box crimper including a stuffer box having a stuffer box channel including a surface consisting of a hard material having a hardness of at least 60 Rc; and (2) crimping via the stuffer box crimper.
