ABSTRACT:
A backing layer and a substrate layer, particularly of fabric-backed tufted carpeting, are bonded together using discrete areas of adhesive applied to one side of the backing layer. The adhesive is applied using a perforated roller (3) with an internal abutment such as a second roller (4). The adhesive material (6) is fed to the inside of the perforated roller (3) and is forced through the perforations with the internal roller (4).
