Guiding element for guiding flexible flat material, has guiding wall that defines guiding surface for flat material that passes over guiding surface, which is interspersed to air blowing out channels

摘要

The guiding element has a guiding wall (6) that defines a guiding surface (4) for a flat material (2) that passes over guiding surface, which is interspersed to air blowing out channels (7) leading from one of the guiding surfaces. The guiding wall is partly made of open-porous metal foam (15). The air blowing out channels are partly made of pores (16) of the metal foam.
