  • Publication number: 20080036135
    Abstract: A stationary working surface of a one roll microcreper member is of plastic resin having low wear and friction properties. As a primary pressing member subject to concentrated force it is 0.040 inch thick. One or both opposed retarder members of a bladed microcreper are of the plastic. Thermoplastics meeting wear and friction limits, e.g. ultra high density polyethylene, are employed. Primary extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. By a load-spreading surface, the thermoplastic primary member is restrained without distortion. By this surface being linear it slideably inserts into a mounting. By this surface being parallel to the roll axis the primary member is free for cross-machine thermal expansion. A primary member shown is sheet form, mounted between sheet metal members, one with a restraint surface. Sheet materials of polyolefins, wood pulp, etc.
