ABSTRACT:
The disclosure relates to process and apparatus for the production of variegated paper, especially including but not limited to paper used in the manufacture of simulated caning material. The process involves the indirect application of aqueous dye solutions to a wet paper web, after formation on the wire and passage of the web through the wet press section, but prior to drying. Multiple jet-like streams of a plurality of dye solutions are directed at the surface of a resilient transfer roller, while being oscillated transversely of the web in an asynchronous manner. Jet-like streams of dye solution apply a relatively wide flow pattern to the surface of the transfer roller, and also cause substantial desirable splattering of the dye solution on the roll surface for subsequent transfer to the wet web, as it passes through a pressure nip formed in part by the transfer roller. The equipment and procedure is highly simplified, reliable yet capable of easy in-process control, all while achieving a uniquely desirable end product having a highly randomized, diffuse variegated design pattern.
