Abstract: In a roller transfer application method for a hot-melt adhesive, a coater head having a slot in a direction towards an axis center of a pattern roller is provided to face a pattern surface of the pattern roller; and by supplying hot-melt adhesive, which is supplied from a hot-melt adhesive supply device, in a thin-film state to a pattern top surface of the pattern roller, thin-film hot-melt adhesive is thus only supplied to the top surfaces of protrusions of the pattern roller. By opening an on-off-type hot-melt adhesive supply control valve, which is attached to the coater head, at a timing that an adhesive opening (the slot) on the bottom surface of the coater head faces application zones on the pattern surface of the pattern roller, the hot-melt adhesive is supplied only to the top surfaces of the pattern roller protrusions.

Abstract: An object of the present invention to make a measure against moisture entry into an edge portion of a double-layered product such as a photovoltaic cell panel or an electronic panel more reliable. A tip end of the coating agent discharge port is arranged to face a part of an edge portion of a double-layered product serving as the work to be coated. An applying nozzle having the slit-shaped coating agent discharge is rotated and driven to allow a direction of the slit-shaped coating agent discharge port changeable as viewed in a planar state.

Abstract: A method and a device for applying an adhesive to an elastic string-like material capable of performing continuous application operation without stopping the application operation by automatically jumping the knot of the elastic string-like material form a running line for the material at a slit groove 202 in a coater applying head. A slide guide body 210 positioned at a front side of the slit plate 201 in a transfer direction, having a detection guide groove 211 with a width of allowing the elastic string-like material to pass through but inhibiting the knot from passing through, and having a second expanded part 205 positioned at a part protruded from a tip end of the slide guide body 210 at a tip end extension part of the slit groove 202 of said slit plate 201, with a width of allowing the knot to pass through.

Abstract: A spiral spray coating method, comprising the step of forming a second pressurizing air flow which is discharged from a number of second pressurizing air holes (13) positioned concentrically with and outwardly-shaped from first pressurizing air holes (12), on the outside of the first pressurizing air flow which is discharged from a number of first pressurizing air holes (12) disposed concentrically with an opening of an adhesive agent hole (11) so as to feed the second pressurizing air flow (K2) to the outside of the first pressurizing air flow (K1) in order to form an air curtain of the second pressurizing air flow on the outside of a spiral of a hot-melt adhesive agent fiber; a spiral spray coating apparatus using the spiral spray coating method.
