Continuous shirring and spinning apparatus for casings

摘要

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.
