Double belt press laminating machine with edge strip bands for manufacturing waterproofing membranes

A system for manufacturing waterproofing membranes, comprising:

• a laminating machine, comprising:
• an upper conveyor belt,
• an upper heat source adjacent to the upper conveyor belt,
• a lower conveyor belt, and
• a lower heat source adjacent to the lower conveyor belt,
• a transport belt moveable through the laminating machine between the upper and lower conveyor belts;
• first and second pairs of edge strips positioned adjacent to opposite sides of the transport belt, the first and second pairs of edge strips being moveable with the transport belt through the laminating machine between the upper and lower conveyor belts;
• and
• a first polymer that is fed through the laminating machine positioned against the transport belt and positioned between the first pair of edge strips,
• a second polymer that is fed through the laminating machine positioned against the transport belt and positioned between the second pair of edge strips, and
• wherein the first and second polymers are positioned on opposite sides of the transport belt, and wherein the first pair of edge strips:
• is positioned directly on top of the upper conveyor belt and wrap around the upper conveyor belt, or
• passes continuously around a plurality of dedicated rollers that position the edge strips on the upper conveyor belt, wherein the edge strips wrap around the upper conveyor belt.
