Finishing process conducting device for e.g. paper, has processing rollers, where one roller built as transport roller has openings to suck and blow air and gripper for registered transport of substrate

摘要

The device has two rotating processing rollers (2, 3) between which an arc-shaped substrate (5) is introduced in a feeding direction. The roller (2) is built as a transport roller and has a gripper (6) for registered transport of the substrate (5). Openings are provided in the roller (2) for sucking and/or blowing of air. The substrate undergoes processing through tools that pass through slits, while introduced between the rollers.
