An inlet channel extends in the nozzle body from the material inlet opening to at least one branch point. At each branch point, two distributor channels extend in the nozzle body in opposite directions from the inlet channel, wherein the distributor channels are each arranged over their entire length at a distance from the material outlet face, and at least one outlet channel extends in the nozzle body from each of the distributor channels in each case to one of the material outlet openings.

A coating device comprises a die with a slit that is longer in a width direction and discharges a coating liquid to form a coating film on a substrate, a first flow path that supplies the coating liquid toward the die, a first manifold that is linked to the first flow path and holds the coating liquid that flows in from the first flow path, a plurality of second flow paths that are linked to the first manifold, a second manifold that is linked to the second flow paths and the slit, is longer in the width direction, and holds the coating liquid that flows in from the second flow paths, and an adjustment unit that is provided along at least one of the second flow paths and adjusts a flow of the coating liquid flowing through the at least one of the second flow paths.

A switchable slotted valve for a coating installation that controls dispensing of a pasty coating material, includes a valve bore incorporated into a valve basic body, oriented in a valve direction of extent and having an inner circumferential surface, a feed duct arranged in a region of the inner circumferential surface of the valve bore and opens into the valve bore, a nozzle duct arranged in the region of the inner circumferential surface of the valve bore and leads out from the valve bore, a valve sleeve arranged in the valve bore and has an inner circumferential surface that delimits a cavity oriented in the valve direction of extent, and an outer circumferential surface, wherein the valve sleeve includes a slot-shaped sleeve inlet opening into the cavity and a slot-shaped sleeve outlet leading out from the cavity, a valve control rod arranged in the valve bore.

A coating device has: a die head that is provided with a supply port into which a coating slurry is supplied, a manifold that stores the coating slurry, and a slit that dispenses the coating slurry; a supply pipe that is connected to the supply port of the die head; and a cover plate that is provided in the supply port or the supply pipe and that reduces the flow rate of the coating slurry at the center of a cross-section that is orthogonal to the direction in which the coating slurry in the supply port or the supply pipe flows into the die head.

The invention relates to a method and to a module (I) for applying a viscous medium (19), in particular an adhesive or lacquer, to a surface (16) wherein the module (I) comprises a reservoir (2) that can be fed with the viscous medium (19), wherein the outer surface (4) of the module (I) comprises an outlet region (5) for the viscous medium (19), wherein the module (I) comprises at least one nozzle channel (6) which fluidly connects the reservoir (2) to the outlet region (5), wherein a smallest diameter (dmin) of the at least one nozzle channel (6) is smaller than 0.8 mm and wherein the module (I) does not comprise any movable parts for closing the at least one nozzle channel (6).

A method is disclosed for dispensing a polyurethane mixture onto a substrate by generating a liquid mixture from reactive component resins; introducing the mixture in an inlet section of a dispensing device so as to advance it towards a planar-shaped outlet slit section, transversely to the advancement direction of the substrate; distributing the mixture along a gap chamber having a cross section diverging towards the outlet slit section; and dispensing the mixture through the outlet slit section, so as to deposit a thin, uniform film onto the substrate. Fractions of the mixture travel equal distances from the inlet section to the outlet slit section, in equal times, maintaining equal average speeds along each section having zones placed all at the same path distance either from the inlet section or from the outlet slit section.
