Abstract: A coating apparatus for controlling processing medium on and in non-woven rollers and on material adapted to pass through rollers is disclosed. The apparatus comprises a pair of non-woven rollers having generally parallel axes and having a porous, generally cylindrical outer surface. The rollers receive and absorb processing medium and have a portion of their adjacent outer surfaces through which material passes in pressure engagement whereby in the regions of the gaps where the rollers engage each other or the material passing therethrough, the processing medium will be of a generally uniform thickness. The rollers have gaps in regions along the edges of the material when the non-woven material passes therethrough. The non-woven rollers will pick-up and carry an excess amount of the medium in the regions to produce a wet edge condition.

Abstract: A roll stand, such as for supporting a pair of adjacent rolls for maintaining a lubricant film thickness on a sheet of steel, tin, or the like, traveling therethrough, is disclosed. The roll stand comprises a first and second, spaced, support members for supporting the rolls extending therebetween. The support members each include a pair of spaced guide rods. Each of the support members further includes first and second spaced carriers slidably carried by their respective guide rods. Pillow block bearings are disposed on each of the carriers for receiving respective ends of the rolls. A pair of hydraulic piston and cylinder devices move each of the first carriers relative to their respective second carriers, to control the pressure between the rolls. A pair of jacks, manual or motorized, move each of the second carriers to adjust the rolls to the proper height.
