摘要： Cellular retroreflective sheeting comprises a first film of thermoplastic material which has been formed to define arrays of minute cube-corner reflective elements on one face thereof. The reflective elements are covered with a second thin thermoplastic film and the two films together pass over a patterned roller where a series of sonic welding heads rapidly bond the films together forming small cells of retroreflective cube-corner elements in the pattern of the roller. Because the heat generated in the welding process is localized to the pattern of the roller, cell walls may be formed having narrow thickness yet good bonding of the films is achieved. Further, residual heat does not appreciably transfer to adjacent retroreflective elements, therefore, distortion of adjacent elements is minimized and a sheeting construction is achieved having superior brilliance and durability as well as maximum retroreflective capability over a wide angular range of incident light. Also disclosed is a method for forming such sheeting.

摘要： A process and apparatus for embossing thermoplastic products having precise microstructured surfaces including using a continuous press having upper and lower belts with the embossing pattern(s); feeding thermoplastic material through the press where heat and pressure are applied to form the embossed pressure microstructure, and cooling the embossed material, all while maintaining pressure. A continuous embossing tool is provided by welding segments together, the welds including interface material at the weld joint which is of a different material than the segment material to increase the tensile strength.

摘要： A process for manufacturing fuel cell plates including a continuous press, a sifter, a leveler and rollers for removing air from resin impregnated graphite. The sifted material is deposited on a heated lower press belt having an embossing pattern. The material is leveled to a predetermined height and squeezed to remove air. An upper belt, also having an embossing pattern, contacts the material and heat and pressure are applied in a reaction zone for a predetermined time period. The finished product is a relatively low cost fuel cell plate.
