System for oscillating a roller

A system for oscillating a working roller disposed between first and second gudgeons slidably and rotatably disposed on a non-rotatable shaft, comprising:

• an oscillating assembly disposed for oscillation and rotation on said shaft;
• and
• an oscillation mechanism disposed for rotation on said shaft and connected to said oscillating assembly,
• wherein said oscillation mechanism comprises:
• at least one tie rod connecting said first and second gudgeons;
• at least one oscillation pin connected to said tie rod and extending radially inwards from said tie rod toward said shaft,
• an oscillation cam rotatable on said shaft and including a first timing element;
• wherein the oscillating assembly is oscillated by the oscillation pin in cooperation with the oscillation cam;
• and
• wherein said oscillation mechanism includes a reduction transmission having a plurality of timing elements rotationally connected in an arrangement to yield a desired rotation ratio between said oscillating assembly and said oscillation mechanism.
