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 member extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. Parallel slots, preferably formed by water jet cutting, defining machine-direction fingers provide particular advantages, often greatest when the fingers begin upstream of the creping cavity, and stated dimensional limits observed. By a load-spreading surface, the thermoplastic primary member is restrained without distortion. A primary member shown is sheet form, mounted between sheet metal members, one with a restraint surface. Sheet materials of polyolefins, wood pulp, etc.

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.

Abstract: A novel open weave endless dryer belt is disclosed which comprises in a leno weave, warp yarns of synthetic organic fibers and crosswise yarns of synthetic organic fibers braided over a core of glass fibers and/or metal wire. The fabric weave is then finished with a coating of a temperature resistant resin. The fabric of the invention is useful for fabricating conveyor belts employed in conveying textiles through dryers and in like applications.
