Abstract
A coating device for cast-coating webs and plates or the like comprises a swivelling casting channel with a cover and a draining trough connected with a supply tank for a coating material through a return line. A suction line leads from the supply tank, via a pump and a hose, to a supply pipe which is inserted in a connecting piece of the casting channel and opens into the interior of the casting channel. An overflow baffle and an underflow baffle are inserted in mountings or grooves, respectively, inside the casting channel. A gap is left open between the cover and the casting channel, through which gap the coating material flows over an overflow edge onto a casting plate which is attached to the outside of the casting channel and points vertically downward. The casting film flows upon the plates or webs conveyed horizontally through the coating device.
