ABSTRACT:
BACKGROUND OF THE INVENTION
Sausage encasing machines extend an extruded encased strand of sausage through a twisting mechanism to impart rotational movement to the strand as the strand exits the twisting mechanism and enters a linking system. This invention involves an improvement in such a twisting mechanism.
Therefore, the principal object of this invention is to provide a twisting mechanism which cools the bearings and other components thereof even while operating at high speed.
SUMMARY OF THE INVENTION
A twister mechanism for sausage encasing has a first housing member having a center bore. A rotatable ring has a center bore concentric with the center bore of the housing. A rotatable sleeve is mounted on the ring and forms the center bore of the ring and being rotatable with the ring. A second housing member 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 extending outwardly from the center bore, and has an outer peripheral edge. A plurality of parallel spaced vanes 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.
