This relates to a machine for shirring tubular films such as those used for sausage casings and the like. In accordance with this disclosure, the films are continuously fed onto a mandrel where they are opened from their flat state and then are fed at a selected rate through a shirring head. The shirred casing is then gripped and advanced in a manner so as to control the density thereof and to impart a spin thereto as desired. The shirred casing, while being spun, is gripped by a pair of cooperating units and a leading portion of the shirred casing is separated at predetermined spacings into individual strands which are then fed along the mandrel individually and are compressed and doffed from the mandrel into a strand handler which then presents each strand to an end closer and thereafter deposits the closed strand on a receiving tray. |
