ABSTRACT:
A heatable shoe for a joint welding apparatus for overlapping joint welding of asphalt roofing is designed in such a way that it will be able to produce a wave of liquid asphalt in an opening or slit between a front and a rear part of the shoe, thereby producing a maximum quantity of liquid asphalt inwards to a line approximately in the center of the overlapping portions between the roofing webs. This is where the mechanical fasteners are located, which are thus baked or embedded in and sealed by in liquid asphalt in a favorable manner.
