Abstract

In curtain coating apparatus a driven roller is located beneath the falling curtain of coating material, the upper surface of the roller being substantially flush with the path of workpiece movement, and means are provided both for removing coating material from the roller and for collecting surplus coating material. By supporting a workpiece in its movement through the curtain, the arrangement facilitates the coating of short and of thin flexible workpieces. A curtain 4 of coating liquid is discharged from a slot 2 in a head 1 for coating workpieces 24 transported to the coating position by an endless conveyor 6 and away therefrom by an endless conveyor 8. Surplus liquid is collected in a receptacle 10 positioned in the gap between the conveyors, and drains via a pipe 50 to a supply tank 26 from which the liquid passes to head 1 via a pump 28 and line 30. Mounted in the mouth 11 of receptacle 10 is a roller 12, the upper surface of which is level with the upper runs of the conveyors. Roller 12, which may be provided with a heater, is driven via a belt 18 from a motor 16 at a peripheral speed slightly greater than the speed of the conveyors. The peripheral speed of roller 12 is also slightly greater than the free fall speed of the liquid when contacting the roller. Liquid is removed from roller 12 by a pair of scraper blades 52.
