P.I.V. 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.
In 1928, Werner Reimers acquired the patent and founded the company
"P.I.V. Antrieb Werner Reimers KG". In subsequent years
the 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 1980s, parallel and right angle shaft gear reducers with
universal mounting arrangements were introduced.
Particular attention was given to the design for extruders, and
P.I.V. went on to accumulate twenty years of experience in this
field.
Brevini Riduttori bought the company early in 2002, renaming it
P.I.V. Drives GmbH and retaining the historic premises at Bad Homburg.
