Abstract
An apparatus and method of applying a bead of TPO or TPE adhesive between a talc-free first roofing membrane and an overlapping talc-free second roofing membrane. The apparatus includes a movably supported chassis and an extruder attached to the chassis having a nozzle including an outlet having at least one opening for applying the TPO or TPE adhesive between the first membrane and the overlapping second membrane to adhere the overlapping second membrane to the first membrane. The TPO or TPE adhesive is heated within the apparatus allowing application along the seam between the first and second membranes. The outlet of the nozzle is positioned between the first and second membranes with the TPO or TPE adhesive applied between the overlapping portions of the membranes while pressing the overlapping first and second membranes to hold the overlapping portions together.
