ABSTRACT:
Method and apparatus for heating and applying sheet material to an supported base surface are disclosed. The apparatus includes a mobile frame for transporting, supporting and permitting a roll of sheet material to be unrolled. The apparatus further includes a heating platen for heating the sheet material along its width and for heating the supported base surface. Pressure rollers are also disclosed for pressing the sheet material against the heating platen to facilitate heating thereof and to the base surface to facilitate welding. In addition, the apparatus includes a release mechanism for pivoting the heating platen and the pressure means in unison to and from operating and release positions. In the release position, the sheet material is separated or spaced from the heating platen to prevent it from being overheated thereby and possibly ignited.
