Abstract
An apparatus for applying strips of thermoplastic material to thermoplastic roofing membranes, the strips each having an upstanding central portion extending lengthwise thereof and opposed flange portions extending widthwise from the central portion. The apparatus includes a self-propelled housing having drive wheels thereon for movably supporting the housing on the membranes. A guide member is mounted on the housing for disposal over one of the strips and is adapted to receive the strip central portion and guide the strip into a position beneath the housing as the housing moves over the strip. A pressure wheel is mounted on the housing rearwardly of the guide member, the pressure wheel having a peripheral groove adapted to receive the strip central portion, and two peripheral edges adapted to engage the opposed flange portions of the strip.
