Film intermittent carrying device and film intermittent carrying method
Abstract:
A film intermittent carrying device: includes a film delivering mechanism, a delivering and accumulating mechanism, accumulating the film and discharging the film, a winding and accumulating mechanism accumulating the film while discharging in an amount corresponding to an amount of the film discharged, and a film winding mechanism taking-up the film constantly. The delivering and accumulating mechanism includes first and second fixed rollers, an upstream-side movable roller moving to pass through a middle position between the first and second fixed rollers, and an upstream-side friction preventive unit configured to reduce a friction between the film and the upstream-side movable roller. The winding and accumulating mechanism includes third and fourth fixed rollers, and a downstream-side movable roller moving to pass through the middle position between the third and fourth fixed rollers, and a downstream-side friction preventive unit configured to reduce a friction between the film and the downstream-side movable roller.
