Method of manufacturing mesh-reinforced thermoplastic membranes

摘要

A method of simultaneously manufacturing multiple mesh-reinforced thermoplastic membranes including providing a roll (14) of mesh reinforcing sheet having a first side and a second side and drawing the mesh sheet through a cutting device to the cut the mesh sheet longitudinally and create a plurality of mesh sheets. The method also includes separating the plurality of mesh sheets to create gaps therebetween and simultaneously extruding (42,44) a molten thermoplastic layer onto both the first and second sides of the plurality of mesh sheets and over the gaps to create a single mesh-reinforced thermoplastic membrane. The mesh-reinforced thermoplastic membrane is then cut (50) longitudinally along the gaps (30) between the plurality of mesh sheets to create a plurality of mesh-reinforced membranes (54,56), each membrane having a pair of longitudinally extending gum edges (58,59).
