Abstract

A method/apparatus closes and finishes an open end of a product that can be fused together with heat. The apparatus includes a bending stage, a fusing stage, and a pressing/cooling stage, which all can be integrally formed, with the bending stage positioned upstream of the fusing stage, and the pressing/cooling stage positioned downstream of the fusing stage. The apparatus can further include a trimming stage positioned upstream of the bending stage for preparing the ends of a panel. The product has a pair of spaced layers with edges that form an open end. Either one or both of the layers can be heated and rolled toward the other layer while being heated so that they contact and fuse together. The layers can overlap and fuse at their contact surfaces, or the edges can abut to form a butt joint, or the edges can overlap slightly.
