ROLLER SUPPORT MEANS FOR ROLLER TWISTING APPARATUS

摘要

A reciprocating roller twisting mechanism including a hollow cylindrical roller supported internally on a pair of bearing members spaced longitudinally thereof, a rod extending from outside the roller through one of said bearing members into the interior of the roller between the bearing members where it is fastened to the roller by fastening means and means to reciprocate the rod longitudinally and simultaneously to rotate it thereby to impart axial reciprocation and simultaneous rotation of the roller on said bearing members.
