Abstract
A system for manufacturing waterproofing membranes, including: a laminating machine; a textile belt moveable through the laminating machine; and a pair of edge strips positioned adjacent to opposite sides of the textile belt. A first polymer is unrolled onto the textile belt and positioned between a pair of edge strips positioned adjacent to opposite sides of the textile belt and then moved through the laminating machine to heat and cure the first polymer into a first waterproofing membrane. The edge strips are preferably endless loops of material that pass continuously through the laminating machine. A second polymer can also be unrolled onto an opposite side of the textile belt such that two different waterproofing membranes can be manufactured simultaneously.
