<p>An unlaminated belt (40) for a single-facer section (10) of a corrugated board production line has a single base structure (52) in the form of an endless loop lacking a seam. The base structure (52) is made up of yarns (56, 54) oriented in the machine, or running, and cross-machine directions of the belt (40). At least one layer of staple fiber material (60) is needled into the outside (58) of the base structure (52), extends at least partly therethrough, and forms a layer (64) on the outside (58) of the base structure. The base structure (52), once so needled, is impregnated with a polymeric resin material (66). The yarns (56, 54) of the base structure, the staple fiber material (60) and the polymeric resin material (66) are all of high-temperature-resistant materials to enable the belt (40) to withstand the conditions under which it must operate on a corrugator machine. <IMAGE></p> |
