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.

Device for later application of a two-component material on a substrate

An installation (,) for conveying a liquid from a container (,) to a carrier material (,). The installation (,) comprises a conduit system with two parallel conduit branches (,). A conveying pump (,) is arranged in each conduit branch (,), and each conduit branch (,) leads to a dispensing head (,). At least one dispensing pump (,) is an intermittently operating pump, in particular a piston pump, while the second conveying pump (,) can be a pump of any arbitrary construction, in particular a continuously operating pump, for example a gear pump. The installation (,) can be used for conveying liquids of various, also temperature-dependent viscosities, such as an adhesive, for example.

Installation for conveying a liquid and use of the installation

The invention relates to a method and a device for the delivery of adhesives, in particular for the delivery of hot melt adhesives in the form of a thin stream of adhesive spray directed onto the product surface and acted upon by at least one air jet. A spray head (,) is arranged at the one end of the device (,), which comprises a connecting housing (,) for receiving a insertion element (,), provided with an outlet opening (,) for the thin stream of adhesive spray (glue) and embodied as a nozzle conduit, a guide sleeve (,), designed for the coaxial seating of the piston rod (,), as well as a nozzle body (,) with bores (,) arranged in the circumferential direction distributed in respect to each other, in which an air nozzle (,) with an interior chamber, which is embodied to be convergent-divergent in the flow-through direction, is respectively arranged.
