Abstract
A discontinuous system applies chemical solutions, dispersions, slurries and pastes to fibrous materials, paper, plastic and metal sheeting, or their composites, confined in one station and capable to wind, rewind and position rolls in sequence and to process sheeting with the ability to interrupt, inspect sections, and add additional windings of the same roll under varied conditions.
Claims10
A system for processing endless materials through a plurality of applicators, winders, resetters, rewinders and storage locations, wherein the improvement comprises:
- a working area;
- a discontinuous modular machine located adjacent said working area for the processing of substrates including fibers, sheeting and batches of cellulosic and synthetic materials, plastics and metal foils in a hostile environment, including a chamber supported overhead and generally closed on all sides, top and bottom, said chamber having a narrow opening slotted at the bottom of said chamber to enter said substrates from said working area, said opening being closed to prevent air from entering said chamber and preventing excess vapors escaping from said chamber to enable said vapors to condense on said substrates as they enter said chamber whereby said condensed vapors are returned to said chamber as condensate on said substrates;
- means at said working area to feed and process said substrates including two dual working stations, each working station equipped with drive means and brake means, to start, brake and stop, wind forward and wind back any number of times;
- additional means to lift and lower said substrates, move said substrates forward and back and to interchange all available options to maneuver said substrates along the x,y-axis of the machine, and means to open the bottom and sides of said chamber to permit the entry and removal of said fibers, sheeting, and batches of cellulosic and synthetic materials, plastics and metal foils.
