Quality – the key to the future

HAVER & BOECKER, wire-weavers and mechanical engineers, of Oelde, Germany, can look back on a corporate history of no less than one hundred and twenty-two years. Carl Haver and Eduard Boecker founded their wire-weaving works in Hohenlimburg, to the south of the present-day Ruhr industrial region, in 1887, their first products taking the form of wire cloths. The company relocated to Oelde, in Westphalia, in 1897, and began, with fifteen employees, the additional production of wire strips for bag closures for the cement industry. Initial contacts abroad had already made it possible to begin and expand exports as the 20th century dawned. The mechanical engineering plant was constructed adjacent to the wire-weaving works, and production of the company‘s first packing machines started, in 1925, to be followed in 1930 by the completion of the first NIAGARA® screening machine. The following thirty years saw the refinement of these machines into high-performance products, their speed and accuracy being a definitive factor in their further development. The first ROTO-PACKER® was commissioned at the Phoenix cement plant (Beckum/Germany) in 1960. Wire cloth also underwent a dramatic leap in quality around this time – this period witnessed the production of the world’s finest wire cloth, featuring 45 000 meshes/cm2 (540 mesh). The development of an extremely diverse range of screening surfaces also played a significant role. The company...
