ABSTRACT:
A positioning arrangement for a cutting machine includes a first gear rotatable about a first axis and a second gear rotatable about a second axis, said second gear being mounted on a spindle which is affixed to the first gear, and the axes being displaced from each other to form an eccentric drive mechanism. In a variation of this eccentric drive mechanism, the spindle for the second gear may be mounted on a linear drive mechanism for displacing the central axis of the second gear relative to the central axis of the first gear.
