Collmann brand enjoying renewed growth – Micro-Poise focusing more closely on retreading sector
When US publication Popular Science Monthly enthused in March 1935 over “modern scientific methods” that enable a tyre casing to be “rebuilt” instead of discarded after a working life of 20,000 miles or so, the retreading industry was still a relative newcomer on the scene. It was less than 20 years since Oliver Rubber introduced pre-cure retreading, and when the Popular Science Monthly article hit the newsstands, one aspect of retreading remained very labour intensive – buffing a tyre was still partially carried out by hand, with steel brushes used to prepare the casing for retreading. This was soon to change; in the second half of the 1930s, a German named Nanno Collmann looked into ways of simplifying this part of the retreading process, and in 1938 his company introduced the world’s first specialised tyre buffing machine. Three quarters of a century later, the Collmann brand is still a name respected by retreaders the world over and the company, under new ownership, retains a strong interest in the sector.
