Abstract:
A device for applying a coating substance consisting essentially of a liquid resin and fine-grained abrasive material onto a continuous paper web for use in the production of an abrasion-resistant laminate, the device comprising:a deflecting roller rotatable about an axis and over which the paper web passes in a travel direction in a looping region; a metering roller forming a gap with the deflecting roller at the looping region and rotatable about an axis generally parallel to the deflecting-roller axis; means for generally synchronously rotating the deflecting roller and metering roller about the respective axes; means including a slit nozzle adjacent the rollers for applying the coating substance to the paper web in the looping region; and a generally rectangular flap of a flexible rubber-like material having a rear edge fixed generally parallel to the axes adjacent the two rollers and lying slackly on the web downstream in the travel direction of the region.
