Abstract: In a process for applying a partial surface coating to a textile substrate, the textile substrate is unwound from a supply roll, preheated to a preheating zone and partly coated in a coating station by a coating head having coating nozzles. The coating compound is melted and supplied to the coating head. The heated coating head is provided within a perforated cylinder. The nozzles of the coating head apply melted coating compound through the perforations in the cylinder onto the substrate. Hot air is applied in the vicinity of a rising portion of the perforated cylinder facing the substrate to provide a clean breaking off of the melted compound from the surface of the perforated cylinder during the application of the coating onto the substrate.

Abstract: A printing method wherein an image-impressing device impresses on an axially elongate substrate surface by flat-bed table-top printing an apparently continuous major stripe of constant width and straight edges in excess of the length of the image-impressing device by repeatedly moving the image-impressing device to successive slightly overlapping and generally longitudinally aligned lengths of the substrate surface to form a longitudinally continuous plurality of minor stripes of generally constant width and generally straight edges not in excess of the length of the image-impressing device. Each of the minor stripes is formed with at least one inwardly tapered end overlapping the end of an adjacent minor stripe to enhance the illusion of a continuous major stripe of constant width and straight edges by enhancing the apparent longitudinal alignment of the overlapping ends.

Abstract: A method for applying adhesive to join two surfaces. A nozzle has a body member and a conical tip extending from an outlet face of the body member. A first pair of gas passageways is disposed on a side of the conical tip opposite a second pair of gas passageways. Each of the four gas passageways has a dispensing orifice at the outlet face of the nozzle body. The pairs of passageways are inwardly directed to project streams of gas, preferably air, parallel opposed sides of the conical tip. Thus, the streams of air converge at a distance from the outlet face beyond the apex of the conical tip. These streams of air cradle a stream of material issuing from the apex of the conical tip and cause an oscillatory asymmetric figure eight deposition of material. The deposition on a first surface has a resonant frequency and has smooth, controlled radius turns at its edges. A second surface is then brought into contact with the first surface while the adhesive is still in a fluid state.

Abstract: A method and apparatus for dyeing a substrate using an array of spray generators. In a preferred embodiment, each spray generator is comprised of a gas port from which an intermittent jet of pressurized gas is directed onto the substrate to be dyed. Positioned along the path of the gas jet is a nozzle from which continuously flows a liquid dye.

Abstract: An apparatus for applying spaced apart discontinuous stripes of a fluid to the surface of a moving web. The apparatus includes a rotating applicator roll partially immersed in a bath of the fluid.
