Cold Glue Head "Sempre 15/30"
Compact and high-performance electric cold glue application head.
The electric cold glue head Sempre 15 and 30 can be used for non-contact application of emulsions with medium viscosity. They excel in durability and high-speed responsiveness, allowing for precise bead and dot application even on high-speed lines. The top of the head is equipped with an adjustment mechanism that allows for fine-tuning of the discharge amount, making it possible to evenly adjust the application amount of each head in a system using multiple heads from a single pump. Options such as 'CleanStart' to prevent skinning at the nozzle tip, a manual discharge switch, and product guides can be selected, enabling implementation in an optimal configuration tailored to production lines and requirements. In the case of Sempre 15, it is an electric head that does not require a genuine controller, allowing for application control from a PLC or similar device.

Detailed information
-
The nozzle shutter "CleanStart" covers the nozzle when the machine is stopped or when no products are flowing, preventing skinning at the nozzle tip. It significantly reduces discharge failures and contributes to reducing the operator's burden by eliminating the need for cleaning the nozzle tip before starting.
-
Trigger sensor can be mounted on the product guide at the discharge head.
-
Glue detection sensor ItaQ-04 can be connected to the pattern controller AS50 to build a detection system. It can process everything from discharge control to glue application detection using Robatech's controller.

Reduce the burden on operators and achieve cold glue application without defective products.
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.

Efficient manufacturing of paper bags with cold glue.
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.

A news article has been uploaded to the official website about stress-free cold glue application. Please take a look at the successful case that improved work efficiency with the folder glue machine using a nozzle shutter.
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. Please take a look at the article and consider what benefits it could bring to your equipment.
