Begins descending and feeds the web (2) by one pitch from the web sending section (5a). At the time of feeding, a constant tension is continuously applied by the upstream tension roller (81c), and at the same time, the feeding peripheral speed management unit (80) measures the feeding speed of the original fabric (2).
