Abstract: A strap feeding device includes first driving and driven rollers, second driving and driven rollers, an actuating unit, and a detecting unit. The actuating unit can move the second driving roller between a released position, where the second driven roller is spaced apart from the second driving roller, and a contact, where the second driven roller contacts the second driving roller and is co-rotatable with the second driving roller to clamp and move a strap. The control device controls rotation of the first and second driving rollers to feed and return the strap, detects rotation of the first driven roller, and controls the actuating unit to move the second driven roller to the contact and released positions.
