ABSTRACT:
A size press having at least one coating nip avoids splashing of the sizing or equivalent coating agent by leading the web to be treated through said nip. Coating supply apparatus supplies coating pools at the nip entrance between a coating roller and the web entering said nip. The coating supply apparatus includes filling pieces in the nip entrance, placed in the coating pool in operating position. The filing pieces consist of permeable, porous, or perforated material and extend along the entire width of the web. The filling pieces suppress the coating pools and prevent or, at least, essentially decrease, the splashing of the coating agent.
