Abstract
A torsion stiff frame formed by a swingable plate, a bracing bar and a hollow member or tube is mounted upon a torsion stiff frame formed by support plates and a round bar defining the pivot axis. The roll carrying arms are engaged with the central tube and braced upon the bracing bar but are shiftable by a threaded spindle driven by a motor externally of a support plate via a shaft passing through an arcuate slot thereon. A shaft also driven by a motor mounted on the support plate coaxial with the round traverse is used to drive the rolls.
