The servo motor drives the upper clamping plate 14 and the lower clamping plate 13 to pull the fabric roll forward. At the same time, the lower release roller 22 and the upper release roller 23 rotate to drive the fabric roll forward. When the upper clamping plate 14 and the lower clamping plate 13 are pulled to the set position, the pulling stops. At this time, the lower release roller 22 and the upper release roller 23 also stop conveying. The pressure plate 33 presses down to hold the nonwoven fabric.
