Abstract

A first shaft control section is configured to control rotation of a first support shaft supporting a first roll such that a sheet is unwound from the first roll at a predetermined running speed. A second shaft control section is configured to execute a first rotation control of regulating a rotational speed of a second support shaft supporting a second roll such that a peripheral speed of the second roll coincides with the predetermined running speed of the sheet of the first roll. The second shaft control section is configured to regulate the rotational speed of the second support shaft by acceleration or deceleration such that an adhesive on an outer peripheral surface of the second roll arrives at a pressing position when a target joining portion of the sheet of the first roll meets the pressing position.
