ABSTRACT:
A method and apparatus is provided for chemically treating articles, often with a liquid treatment fluid that is corrosive, while the articles are being delivered along a path through a substantially closed chamber. During treatment, the articles pass through a nip formed between opposed rollers, at least one of which is rotatably driven. Because of the thickness of the articles, at least one roller of the nip must be moved away from the other roller in order for articles to pass through the nip. The roller being moved remains positively driven as it moves away from the nip and remains driven until the nip is again closed, all without interferring with the drive.
