Abstract:
1. A method for making a laminate, comprising: extruding a core layer, and advancing the same along a processing line; advancing upper and lower metal layers above and below the core layer, and bending the upper metal layer to form a raised bent structure while advancing the upper metal layer; laminating the upper and lower metal layers with the core layer by passing the upper and lower metal layers and the core layer through a nip of a pair of laminating rollers, one of which has an embossing groove that is shaped to complement the raised bent structure and that permits the raised bent structure to pass therethrough; and embossing the core layer to protrude into the raised bent structure while the core layer and the upper and lower metal layers are passed through the nip; wherein the upper metal layer is angled relative to a tangent line passing through the nip by an angle of less than 15 degrees when the upper metal layer is at a position immediately upstream of the nip; and the advancing of the core layer includes the steps of:
