Abstract:
A coating apparatus for controlling processing medium on and in non-woven rollers and on material passing through said rollers, the apparatus comprising a pair of non-woven rollers having generally parallel axes and each having a porous, generally cylindrical outer surface, said rollers to receive and absorb said processing medium, said rollers having a portion of their adjacent outer surfaces through which said material passes in pressure engagement whereby in regions where the rollers engage each other or the material passing therethrough, the processing medium will be of a generally uniform thickness; said rollers to have medium collecting gaps in regions along edges of the material when said material passes therethrough whereby said non-woven rollers will pick-up and carry an excess amount of said medium in said regions to produce a wet edge condition; and a preconditioning roller disposed adjacent and generally parallel to one of said non-woven rollers and in generally uniform pressure engagement with said roller to squeeze said non-woven roller at least across the width of said roller beyond the edges of the material to be processed therethrough, to thereby wring said medium from said gaps. whereby the processing medium will be uniform across the surface of said roller at least in the area through which the material adapted to be processed passes.
