PURPOSE: To enable the production in one process of the titled material which can be used as a cover of a side-ditch and other applications, by a method wherein perforations are bored in an uncured beltlike object containing thermoplastic resins, long-sized reinforcing materials and the like by means of belt conveyors in a particular shape, and the work is then heat-cured.
CONSTITUTION: Uncured beltlike object 16, consisting of thermoplastic resins 112 and 122, and long-sized reinforcing materials 111 and 121, or uncured beltlike object 16, which is in a sandwitched state or in a multilayer state, consisting of the aforesaid beltlike object 16 and molding material layer 15 containing thermoplastic resin and fillers, is passed through between a pair of belt conveyors 17 and 18 in which a large number of cnvexities 171 and holes are positioned facing and opposite to each other to bore a great many perforations in the beltlike object. The work is heat-cured to obtain the grating.
