Abstract
Holding rollers (2), with ratchet (5) to restrain reverse movement are used in forwarding the strip which requires hold to be released from time to time. An alternative form for the holding rollers is also described, in which the upper rollers is mounted on a sub-frame within the main frame, the sub-frame turning on an axle slightly offset from the vertical through the axles of the rollers, in such a way that reverse movement, with friction, increases the holding pressure between the rollers. A further variant provides self-centering rollers which combat any tendency for the strip to wander sideways.
