Device for guiding of material sheets or material webs has guiding surface with air blast holes to create compressed air cushion and air suction holes to create vacuum regions distributed over air cushion

摘要

The device for the guiding of material sheets or material webs, especially in conjunction with printing or other process actions, has a guiding surface (12) along which the material moves. Upon the guiding surface are provided a number of air blast holes (13) to create a compressed air cushion (15), and a number of air suction holes (18) to simultaneously create vacuum regions (23) distributed over the compressed air cushion in such a way that the material sheet (10) or web is drawn through the vacuum regions onto the air cushion and guided spaced away from the guiding surface.
