Brazilian printer adds Polar diecutting label system

Congraf, a Brazilian label converter dedicated to packaging printing, has purchased a Polar diecutting system DC-11 to increase productivity in the paper label section. This new Polar system consists of a loading table, an AC 25 stack cutter, a die punching unit DC and a single-headed banding unit BD.

The system works in connection with a Polar 137 to pre-cut the strips of labels.

Congraf is a packaging printer with 40″ offset printing presses. The company is located in a 15,000 square meter industrial building in the south of Sao Paolo, producing labels in three shifts, six days a week. Since the machine start-up, performance has increased in terms of speed, quantities, and cutting quality and precision.

The transition from manual diecutting processes to automation with DC-11 has allowed the productivity to improve by double digits, especially in the product segment of beer labels.

An essential component of the Polar System DC-11 is the automatic cutting machine Polar Autocut 25 (AC 25). A pusher device on the loading table feeds the automatic cutter with pre-cut label strips. The AC 25 cuts them into label stacks. Subsequently, a swivel unit transfers the stacks to the feeder of the die punching unit DC.

After diecutting the label stacks, a pusher automatically transports the processed labels to the single-headed banding unit BD. Because the single-headed bander uses ultrasonic technology, preheating is not necessary. The ultrasonic welding unit also prevents annoyance caused by a bad smell. This workflow offers excellent performance of up to 960 bundles per 60 minutes.
