Abstract

824,025. Corrugating sheet materials. CHLORIDE ELECTRICAL STORAGE CO. Ltd. Jan. 13, 1958 [March 25, 1957], No. 9639/57. Class 141. [Also in Group XXXVI] Resin-impregnated fibrous sheet material i is formed with permanent ribs p on one face by passing it between a ribbed roller f and a series of transverse laths d carried by an endless conveyer. The ribs g on the roller engage between the relatively widely spaced laths as they pass round the supporting wheel n, and thus form corrugations in the material. As the lath-conveyer follows a straight line after leaving the wheel n, the gaps between the laths decrease and the corrugations are tightly pressed. The laths and corrugated material then pass through a curing oven where the resin is cured together with an adhesive which was transferred to the walls of the corrugations from the ribs g in the forming process. Specification 749,778 [Group XXXVI] is referred to.
