Brands and Products | BST Group


From Web Guiding to Full-Service Quality Management

BST’s success story began in 1979 in Bielefeld, with new products for web guiding that would revolutionize the market – with hitherto unknown reliability for the quality assurance of production processes and the increase of productivity in web-processing industries. The BST company, then a subsidiary of EMG Automation, the number-one company for intelligent automation solutions worldwide, went on to increase its technological advantage. Today, EMG Automation is part of elexis AG, which in turn belongs to the SMS Group. As a full-service provider of quality assurance systems for the web-processing industries, the BST Group has successfully established itself on the market internationally.

Bundled Expertise, Continuous Growth

Major customers settled on BST technologies early on. In the 1980s, the BST product portfolio was substantially expanded with web monitoring, automation, and register controls. New branch offices, subsidiaries, and partnerships came into being in Europe, America, and Asia.


In the year 2012, one of the leading providers of control technology, AccuWeb, Inc., joined the BST Group. Founded in 1984, AccuWeb sets industry standards with a broad product portfolio including sensors, controllers, actuators, and guiding devices. As a result, the BST Group has simultaneously become the market leader for measurement and control technology in the USA. Likewise in 2012, BST ProControl – which emerged from the established companies betacontrol Measurement and Control Technology and P2T Protagon Process Technologies – became part of the BST Group. With its new, strengthened network, BST is continuing to set standards in quality control and process optimization.


In 2014, eltromat, the pioneer and world’s leading manufacturer of optical quality measurement and control systems, became a member of the BST family. Founded in 1960, eltromat developed the first register control with electronic color control already in the 1960s, in Leopoldshöhe in East Westphalia. With the first camera-based color web monitoring device worldwide, 100% inspection system, plate scanner, and integrated print quality system, eltromat was responsible for outstanding technical innovations.


The successful businesses BST eltromat, Nyquist Systems and the AccuWeb brand, among others, belong to the BST Group today. Together, with additional subsidiaries and international agents, they impress customers worldwide with a one-of-a-kind product portfolio for quality management in the web-processing industries.
