ABSTRACT:
An apparatus and method are disclosed for forming laminar sheet materials comprising a base material having overlay strap material dielectrically sealed thereto at spaced locations along the length of the base material. In accordance with the method, the strap material is positioned under tension adjacent an electrode bar for dielectric sealing to the base material and the lateral edges of the strap material are confined between retractable guides extending along the sides of the electrode bar. The strap material is tensioned and laterally confined until it is fixed to the base material by dielectric sealing. A dielectric sealing press including a strap feeder for tensioning and confining the strap material is also disclosed.
