Abstract

A method and apparatus are disciosed for use with a paper coater located on a backing roll (10) of, for example, a papermaking machine. An apparatus in the form of a hinged bridge is used to collect excess coating liquid from a remote doctor blade (37) or a first coater (16) having such blade and supply the same to a second coater (18). The bridge may be attached to the doctor blade (37) or to the first coater (16) so that it can be placed in a bridging position (A) accommodating various angles of the doctor blade (37), or in a second stored position (B) wherein it will not interfere with the operation of either coater or the doctor blade.
