Abstract: A twister mechanism for sausage encasing has a first housing member (12) having a center bore. A rotatable ring (22) has a center bore (26) concentric with the center bore of the housing. A rotatable sleeve (24) is mounted on the ring and forms the center bore of the ring and being rotatable with the ring. A second housing member (14) is secured to the first housing member and has a center bore receiving the sleeve. A bearing member extending around the sleeve and extending radially to engage a surface of the second housing member. The ring includes a circular disk (28) extending outwardly from the center bore, and has an outer peripheral edge. A plurality of radially spaced vanes (32A) are on the disk extending outwardly therefrom. The vanes are spaced from the second housing member and the bearing to enhance the cooling of the mechanism when the ring is rotated.
