Its importance has constantly grown to date. In the 15th and 16th centuries, Leonardo da Vinci and Galileo Galilei already expressed thoughts about flexure loading and the elastic properties of materials. The first testing machines for these purposes were made in the middle of the 18th century in France. The Amsler company in Gottmadingen (formally in Schaffhausen, Switzerland) has been involved with materials testing since the middle of the 19th century. The Roell & Korthaus company started producing instruments, machines and systems for material testing in 1920. Zwick started producing instruments in 1937. The Zwick Roell group of companies was brought together in 1992, and now markets a complete line of systems from hand operated hardness testers to complex computerized testing systems. This brochure gives an overview of the instruments, machines and systems of the Zwick Roell Group for paper-based materials. Its purpose is to give suggestions and hints to all, who have even the smallest interest in paper testing. Many years of experience, a multi-tude of delivered equipments and constant communications with users, are the basis of our machines and instruments. Fig. 1: Paper then and now We achieve high flexibility and „intelligence“ of our systems with modern mechanics, high performance electronics and user-oriented software. The performance of the Zwick Roell Group reaches far beyond the delivery of testing instruments. The company was certified to DIN EN ISO 9001 in 1994, which guarantees a high degree of product and service quality. As an accredited DKD Calibration laboratory, Zwick is also authorized to check and calibrate testing systems. Internationally recognized certificates help to compete in international markets.
