Abstract
A roll feeder is usable to intermittently feed a coiled material. The roll feeder includes a paired first roll and second roll, a meandering detector, a pressing component, and a controller. The paired first roll and second roll are disposed so as to clamp the coiled material. The paired first roll and second roll are configured to feed the coiled material in a conveyance direction. The meandering detector is configured to detect meandering of the coiled material from a specific conveyance position in a width direction perpendicular to the conveyance direction of the coiled material. The pressing component is configured to press the first roll against the coiled material being conveyed. The controller is configured to control the pressing component so as to correct the meandering based on detection by the meandering detector.
