Found a folder full of interesting knitting history in amongst the stuff I am selling for a friend. Thought this might interest the Toyota owners (not sure if the machine history is complete):
Aisin Seiki Co Ltd, founded in 1949 as a manufacturer of automotive parts and sewing machines, has since grown into a principal international supplier of components for engines, driving systems, suspension, brakes, clutches and bodies, as well as home appliances and industrial machinery.
An important member of the Toyota Group, which supplies parts to the Toyota Motor Corporation, Aisin is also known for its strong independence. For home use, Aisin manufactures knitting and sewing machines, electric appliances, and beds: for industrial use, it makes precision metal molds, large transfer machines, and sewing machines.
Aisin’s intensive research and development continues to produce new products and improve on existing ones, such as metallic fibres, cryogenic freezers, the Stirling engine, and a drive unit for artificial human hearts.
As leader of the Aisin Group, which comprises eight affiliated companies in Japam, Aisin confidently offers innovative high-quality products and home and internationally. The company has nine subsidiaries overseas and one affiliate each in North America, Latin America, Europe, Southeast Asia, and Oceania.
