Abstract
A jet type coater with a nozzle orifice is provided with an adjustable, internal filter or screen in the head of the coater. The filter has orifices or slots which are formed by relatively movable members and is adjustable to a size smaller than that of the nozzle orifice, to keep the nozzle orifice unclogged and functioning. The internal filter is also easily clearable on the run without shutdown and cleanable with coating liquid and/or water.
