Abstract
A web holding unit is provided just in front of a cutting and splicing unit. The holding unit is comprised mainly of multiple pass rollers, a pass roller motor, a vacuum pump, and an up/down cylinder. As the unwinding of an old web comes to an end, a rod of the up/down cylinder extends, and the pass rollers of the holding unit abut against the old web. The pass roller rotates at lower speed than web transport speed, and during the transport, the old web is drawn onto the pass rollers by sucking of the pump. The old web is transported to the cutting and splicing unit with a position thereof being regulated by the holding means.
