Sheet inspection station with pneumatic sheet guide.

摘要

A process for guiding a sheet (2) of material through a sheet inspection station (3), and a sheet inspection station (3) using the process employ pneumatic means for guiding the sheet (2) past one or more measurement sensors (16; 17; 18) in non-contacting fashion, thus eliminating measurement error resulting from fiber/dust buildup associated with friction between the sheet (2) and conventional guide rails (23).
