Abstract

A device for dispensing adhesive on a substrate comprises a writing head with a first dispensing nozzle and at least one second dispensing nozzle. The device can be operated in two operating modes and is configured to perform the following steps for the change from the one operating mode to the other operating mode: —lifting of the writing head, retracting or extending a pin, and lowering of the writing head to a predetermined working altitude, wherein the tips of the dispensing nozzles reach a substantially similar altitude above the substrate in the retracted state of the pin, and wherein the tip of the at least one second dispensing nozzle reaches a higher altitude above the substrate than the tip of the first dispensing nozzle in the extended state of the pin.
