ABSTRACT:
A device for removing curl, folds and the like from a moving web in which opposing banks of elongate fins cooperate to define a web passageway therebetween. The banks of fins are preferably associated with top and bottom plates, respectively, that may be biasable apart by seams, etc., passing therebetween, and may include quick release coupling to facilitate assembly and disassembly of the device without affecting the process with which the device is employed. Relative positions of the top and bottom banks of fins may be adjustably controlled. Preferred different fin spacing permits the handling of webs of varying weights and construction. Fin banks are of unitary construction from material exhibiting a low coefficient of friction as exemplified by ultra high molecular weight polyethylene.
