Cold Glue Head "Sempre 15/30"

At CCE International 2025 held in Munich, David Trinkner, Business Development Manager (in charge of the converting industry) at Robatech, commented on the exhibition content and current industry trends. What notable technologies and market movements emerged through three questions from the perspective of industry trends? For more details, please visit our website newsroom.

Machine stoppages during cold glue application are troublesome. By using Robatech's "Sempre Head" and "CleanStart Nozzle Shutter," stress-free cold glue application can be achieved. Cold glue dries (skins) at the nozzle tip of the application head within 1 to 2 minutes. Therefore, it is necessary to seal the nozzle. During interruptions in application, this task is automatically performed by the "CleanStart Nozzle Shutter." At Flatz GmbH, we tested the performance of our nozzle shutter on a folder gluing machine. We will introduce interesting insights gained from this test by Flatz on our website's newsroom.

By using Robatech's electric cold glue application head, it is possible to manufacture paper bags efficiently and reliably. The fast operating speed and precise control of the adhesive enable accurate contours and sharp edges for flat application. As a result, craft paper is saved, and the paper edges do not excessively protrude on the inside of the bag. With just two types of application heads, Presto and Sempre, flat application can be achieved for any application width and bead, ensuring a secure bond between the flat handle and the paper bag.

Are you familiar with the unique nozzle shutter that can be installed on Roatech's cold glue? It prevents the nozzle tip from drying out and skinning during machine downtime, allowing for a smooth restart of the machine. Since cleaning the nozzle tip before restarting the machine is no longer necessary, it reduces the burden on the operator. Additionally, even during brief stoppages of just a few seconds, the shutter protects the nozzle tip from drying out, ensuring consistently accurate and reproducible cold glue application.
