Abstract
A combination heat applying and roofing material unrolling apparatus is provided. The apparatus includes a frame assembly and a heating support unit. Connecting means interconnects the frame assembly and a roll rod which engages a roll of the roofing material. Guide means having slots are joined to the connecting means. The slots receive a common pipe of the heating support unit. A plurality of burner elements are connected to the common pipe to emit flames for softening an adhesive layer of the roofing material. The common pipe is adjusted laterally and rotationally with respect to the roll of roofing material to permit application of different heating temperatures to the adhesive layer as the roofing material is unrolled.
