Abstract
A first shaft control section controls a first support shaft so that a sheet is unwound from the first roll at a predetermined running speed. A second shaft control section executes an adjustive control of adjusting at least one of a rotation start time and a rotational acceleration of the second support shaft so that, when a first joining target mark on the sheet of the first roll moves to a first reference position, a second joining target mark on an outer peripheral surface of the second roll arrives at a second reference position in a rotational direction thereof, and a peripheral speed of the second roll coincides with the running speed of the sheet of the first roll.
