History of rubber mixing. Posted on August 20, 2010 by jainthomas. Early compounding took place either in single rotor machines such as Hancock's Pickle, or on two roll mills. The first use of the tworoll mill was in the 1830s in the USA. Hancock's Pickle was patented in 1837, although models had actually been in use from the early 1820s .
