Abstract: A slotted nozzle for discharging a liquid adhesive to a narrow edge of a substrate includes a nozzle body, a nozzle slot formed in the nozzle body, a passage in the nozzle body for supplying the adhesive to the nozzle slot, and a slot-shaped outlet opening of the nozzle slot. The nozzle body is configured in the region of averted ends of the nozzle slot that are based on the longitudinal extent of the nozzle slot in such a manner that an increased outlet of the adhesive through the outlet opening takes place in the region of the averted ends of the nozzle slot.

Abstract: A device for applying adhesive to a substrate, having an application roller that is rotatable about an axis, an installation for dispensing adhesive to a circumferential area of the application roller, a dispensing region of the application roller for dispensing adhesive from the application roller, and having a doctor blade, wherein the dispensing region for adhesive in the rotation direction of the application roller is located behind the installation for dispensing the adhesive to the application roller and ahead of the doctor blade. In such a device it is provided that the application roller is rotatable about a vertical axis and the excess adhesive wiped by the doctor blade reaches a collection installation that is located below the doctor blade. In a method for applying adhesive to a substrate, excess adhesive that has not been applied to the substrate is disposed of.

Abstract: The invention relates to an application head for dispensing a free-flowing medium. The application head comprises an injection chamber inside the application head and an injection needle movably mounted inside the injection chamber. An opening movement of the injection needle opens an outlet. A supply channel and a supply line are also provided in order to introduce the free-flowing medium into the injection chamber. A drive generates the opening movement of the injection needle. The application head also comprises a lever arm, the first end of said arm being movably fixed to a rear end of the injection needle and the second end thereof being connected to the drive. A membrane suspension comprising a membrane is provided, and the lever arm extends through the membrane of the membrane suspension. The membrane suspension is used to movably connect the lever arm to the application head, and as a seal to prevent the free-flowing medium from leaking out.

Abstract: A device (10) for applying adhesive to the ribbed side of corrugated cardboard (16), wherein the device (10) comprises a nozzle (15) which discharges liquid adhesive while the ribbed side of the corrugated cardboard moves past at a distance (A) below the nozzle (15). The distance (A) can be adjusted in such a way that adhesive is only applied to the ribbed side in the upper region of the ribs.

Abstract: Apparatus for use in a system which dispenses, for example, adhesive capable of flowing, that melts with increasing temperature. The apparatus includes a container (10) to receive adhesive and a melting device (19, 25) to induce the rise in temperature, so that part of the adhesive is changed into a fluid state. An outlet zone (19) is provided, having at least one passageway (20) for the adhesive capable of flowing.
