ABSTRACT:
An apparatus for making a composite roofing material includes a reel support for reels of each of a vulcanized rubber sheet, a polymeric film and a fleece matting and pinch rollers which advance the rubber sheet from its reel through a path including an abrading roller, a cleaning and scrubbing vat, a stretcher, a heater and then, along with the polymer film and the matting, through a pair of compression pinch rollers. The cleaning and scrubbing vat effectively removes the non-stick talc coating from the vulcanized rubber. The thus cleaned rubber sheet is heated by the heater to a temperature which is sufficient to melt the polymeric film as it comes into contact with the vulcanized rubber sheet. The melted film acts as an adhesive to cause the fleece matting to adhere to the vulcanized rubber sheet as the rubber sheet, the polymeric film and the fleece matting are compressed together by the compression pinch rollers. When the rolls of polymeric film and fleece matting are somewhat narrower than the vulcanized rubber sheet, a selvedge is left along one or both sides of the roofing.
