Waterproofing membrane manufacturing system
The patent US12059879B2 outlines a system designed for the manufacturing of waterproofing membranes, featuring a specialized laminating machine. This machine includes an upper and lower conveyor belt, each equipped with adjacent heat sources, and a transport belt that moves between them. The system incorporates a pair of edge strips that are positioned alongside the transport belt, ensuring full contact with both the upper conveyor belt and the transport belt. These edge strips can either wrap directly around the upper conveyor belt or pass around dedicated rollers, facilitating their movement through the laminating machine. The transport belt can be made from various materials, including textile or polyester scrim PET, and is designed to be unwound from one roller and re-wound onto another after processing.
Additionally, the system allows for the introduction of polymers during the laminating process. A first polymer is positioned against the transport belt between the edge strips, with the option for a second polymer to be applied on the opposite side. The first polymer can be EPDM, and the edge strips may be constructed from materials such as silicone rubber or butyl. This configuration not only enhances the waterproofing capabilities of the membranes produced but also streamlines the manufacturing process by integrating multiple polymers and edge strip functionalities within a single machine setup.
