OTM Avistryk taps DCOS for large Bosch Rexroth retrofit

DCOS Sweden AB has announced a substantial contract to retrofit the existing Bosch Rexroth drive system at OTM Avistryk Herning-Ikast A/S in Ikast, Denmark. The existing equipment consists of two GOSS Universal 45 presses, with a total of twelve 4-high printing towers and two folders installed in early 2000, comprise over 70 drives and motors. The presses are supported by an EAE press control system and AMAL splicers.

In the 1990s, Bosch Rexroth, with its well-known brand Indramat, took part in transforming the graphic arts industry from traditional mechanical line shafts to shaftless drive transmission. In the last 20 plus years, Shaftless technology has been the predominant method to run and control printing presses and industry leading OEMs like KBA, Goss, DGM, and Solna rely on Bosch Rexroth´s technology. Many of these presses were equipped with the DIAX series of drives and CLC motion controller. All based on SERCOS II fiber optics. Like all electronics, the service life of components is limited and especially on power electronics making the DIAX system a challenge to maintain today.

OTM Avistryk realised a few years back that they needed to extend the operational life of the Bosch Rexroth system on their Goss presses to fight obsolescence and to ensure uptime of their presses. DCOS offers custom-designed automated solutions with a focus on user-friendliness, efficiency and reliability – the aim is to maximise the productivity of the customers. DCOS offers a new approach in operation and control systems, operator interfaces, production follow-up and camera-based inspection systems for new and printing press installations, including retrofitting of existing ones.
