Adolf Saurer AG was a Swiss manufacturer of embroidery and textile machines, trucks and buses, under the Saurer and Berna brand names. They were based in Arbon, Switzerland and were active between 1903 and 1982. Their vehicles were widely used across mainland Europe, particularly in the interwar period.


Two of Franz Saurers sons began building hand embroidery machines in their father’s foundry in 1869. By 1873 F. Saurer & Sohne was the leader among the Swiss in terms of sales and total machines built.


Saxony, Germany, was a centre for embroidery and machine development. By the 1890s German companies were Saurers strongest competition. In the late 1870s, a new, faster machine was invented. It was known as the schiffli machine, with a Jacquard punch card reader, to fully automate the process. Saurer developed their own card reader, whilst improving stitch rate and the machines width.


Embroidery as an industry, experienced many ups and downs due to fashion, trade policies and world wards. Saurer diversified into petrol and diesel engines, and then trucks, to reduce the volatility of the market.


From 1903 the company’s engine division focused on commercial vehicles and gained a good reputation. They ran subsidiary companies in Austria, France, the UK and in Germany. They also had a manufacturer under license in Italy and Poland for their engines. In the US, Saurer Motor Truck Company was headed by C.P. Coleman. They had the rights to manufacture and sell heavy trucks under the Saurer brand name in Plainfield, New Jersey.


They had 4 basic ranges of Saurer trucks, A-type (1918), B-type (1926), C-type (1934) and D-type (1959). It was the B-type which established Saurers international reputation as a builder of reliable trucks.


The company also developed Aero engines under license in 1917. They also developed their own designs and built two prototypes of a V12 design in 1918.
