Abstract: A device for spreading a two-component coating material, including at least two components, on a flat web-shaped carrier includes a slotted nozzle provided with an output slot whose length defines the width of the coating material application to the carrier, wherein the slotted nozzle is provided with two end areas and a nozzle chamber which is arranged inside the slotted nozzle and extends in a parallel to the output slot from the first to the second end area. A first mixer is arranged in the region of the first end area. A second mixer is positioned in the region of the second end area. At least one first reservoir for the first component and at least one second reservoir for the second component are provided. A transport mechanism is used for individually transporting the first component from the first reservoir to the first and second mixers and for transporting the second component from the second reservoir to the first and second mixers.

Abstract: A device for clocked dispensing of portions of a pasty compound, having a nozzle body, which has a vertical main channel terminated on top and a feed channel for feeding the pasty compound. The nozzle body comprises a multiplicity of distribution channels running transversely to the main channel, each having an entry cross-section on the main channel and each having an exit cross-section, and a dispensing area, into which the exit cross-sections of the distribution channels open out. The distribution channels have a distribution channel area rising in the flow direction of the pasty compound.

Abstract: The invention relates to a device (1) for applying heated adhesive and/or hot glue having at least one application head (2) having at least one nozzle (3) and a controller for the delivery of the heated adhesive and/or hot glue through the nozzle (3), the application head (2) being sheathed by a housing (4) and the housing (4) exposing an opening (5) for the nozzle (3) in such a way, that the nozzle (3) is enclosed on at least two diametrically opposite sides by at least two webs (6a, 6b).

Abstract: A device (10) for spreading a two-component coating material (1), consisting of at least two components, on a flat web-shaped carrier (16) comprises a slotted nozzle (11) provided with an output slot (11.2) whose length (L) defines the width of the coating material (1) application to the carrier (16), wherein the slotted nozzle (11) is provided with two end areas and a nozzle chamber which is arranged inside the slotted nozzle (11) and extends in a parallel to the output slot (11.2) from the first to the second end area.
