The story of BIRN dates all the way back to 1896, when journeyman former and foundry worker Heinrich Peter Christian Birn founded the foundry in the middle of Holstebro. During the first many years, BIRN nourished itself mainly by producing cookers, stoves, cleaning doors and cake crushers. And the foundry also supplied the castings to F. L. Hansen’s machinery, which was located directly opposite the foundry.
After working with F. L. Hansen's machine factory for a number of years, Valdemar H. Birn, who had now taken over the company after his father, decided to expand the cooperation. Therefore, in 1932 he acquired the machinery.
During the following years, the company grew larger and the foundry business developed as it gained more experience in the foundry industry. In addition to various moulds of machine production, the machine factory had also been tasked with processing castings for customers, and therefore it had become familiar with V-belt pulleys on various occasions. And that was ideal from the company's point of view.
This resulted in the idea of also incorporating V-belt pulleys in our own production as the product was ideally suited for our company, since the finished product contained relatively much processing. The production of the V-belt pulleys continued to this day, with the majority of these now being produced by a partner in China as well as by BIRNS German subsidiary, which also sells and distributes all the pulleys.
