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).

Abstract: A flexible laminate, such as backed tufted carpeting, is formed by bonding a fabric or polymeric backing layer to a pre-coated textile substrate. The substrate is pre-coated by advancing it past a perforated hollow transfer roller (3) containing an internal doctor member (4). Fluent settable coating material is fed to the substrate (1) so that it forms a well (6) between the substrate (1) and the doctor member (4) through the perforations of the roller (3). Coating material is deposited on the fabric (1) and is then set, for example by passing through an oven, to form the pre-coat. The spacing of the roller (3) and the substrate (1) and the pressure of the doctor member (4) on the perforated wall of the roller (3) are adjusted so that a pre-coat of desired thickness or density is obtained.

Abstract: A solid flexible polymeric material is formed by solidifying a water-based latex which contains an inorganic filler. The filler is sand and this may be stabilized in the latex with xanthan gum. The solid material may be a foamed or non-foamed layer which may be used as integral carpet backing, as carpet underlay, or as an adhesive for bonding a reinforcing fabric to the back of carpeting.

Abstract: A coating material is applied to a surface, such as the back surface of carpeting, using a perforated roller. The material is supplied to the outer surface of the roller so as to form a well of material on the surface passing through the perforated body of the roller up to a second similar roller inside the perforated roller. The roller may be fixed or may be driven depending on the nature of the pattern to be applied to the coating material by the roller.
