Abstract
A graphic machine or plotter comprising a feed roll (30) for continuously supplying a print medium such as paper (20), driving means (24) for driving the paper supplied by the feed roll to produce a drawing on the paper, and a take-up roll (40) for receiving the paper after the drawing is produced. The feed roll (30) and the take-up roll (40) are linked together in such a way that the rotation of the feed roll (30) in a forward direction for which the paper is payed out from the feed roll drives the take-up roll (40) to wind up the paper but the rotation of the take-up roll (40) in the reverse direction does not drive the feed roll (30).
