Gluing nozzle, especially for gluing DVD-discs

摘要

A nozzle for simultaneous application of a string of glue on two facing adjacent disc surfaces, especially for gluing together two optical disc elements to form a DVD. In order to make possible higher glue application rates and smaller dimensions of the glue application nozzle, the nozzle can steer the flow towards the facing disc elements. For this purpose, the nozzle has a channel outlet opening which has upper and lower outlet areas and therebetween a constricted outlet area.
