Structured surface for print substrate guiding units of printing machine, has print substrate guiding units transporting print substrate along given path and forming air flows parallel to transport direction of print substrate

摘要

The surface (1) has print substrate guiding units transporting a print substrate (5) along a given path and forming air flows (3) parallel to a transport direction of the print substrate. An extension of structural components (1.P) is provided perpendicular to the surface such that the bumps of the surface are formed with the structural components through a laminar wall layer of the air flow. The structural components have 2 to 4 lines of the thickness of the laminar wall layer.
