ABSTRACT:
A strip, such as paper in a printing mechanism, is transported over a friction roll either along a first path, in which the paper is driven by rotation of the friction roll by a drive motor through an overrunning clutch; or along a second path in which the paper passes over the friction roll and is taken up on a take-up roll, the pull of the strip onto the take-up roll causing the friction roll to rotate faster and disengaging the clutch. Two strips may be passed through a nip between the friction roll and a pressure roll. The pressure roll is driven by coupling to the friction roll so as to have a slightly higher circumferential velocity.
