Abstract
A method of simultaneously manufacturing multiple mesh-reinforced thermoplastic membranes including providing a roll 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 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 longitudinally along the gaps between the plurality of mesh sheets to create a plurality of mesh-reinforced membranes, each membrane having a pair of longitudinally extending gum edges.
