PIV stands for "Positive Infinitely Variable" drive, the name given to a power transmission system using a slatted steel chain, invented in 1924 by G.J. Abbott.
Werner Reimers saw the importance of this invention, acquired the patent and founded the company "Ketten- und Getriebe GmbH" in 1928, which was renamed in "PIV Antrieb Werner Reimers KG" 1936. In subsequent years the PIV system was developed and improved, finding application in a wide variety of fields and evolving ultimately into the high performance Continuous Variable Transmission, which became the basis of the Multitronik transmission adopted by the automobile industry.
During the late seventies, parallel and right angle shaft gear reducers with universal mounting arrangements (Posired series) were introduced. Their universality and ease of application guarantee optimal adaption in almost all areas of mechanical construction and satisfy the requirements of most various Customer needs.
Particular attention was given to the design for extruders, and PIV went on to accumulate twenty years of experience in this field.
Brevini Riduttori bought the company early in 2002, renaming it PIV Drives GmbH and retaining the historic premises at Bad Homburg.
