Company Portrait of Linneborn Metallwaren GmbH

The Linneborn company was founded in 1871. It is currently in its fifth generation. From the year of its foundation, wood pulp (a precursor for cardboard production) was manufactured. Water power served as the energy source for this production. Large millstones were mechanically driven by transmission shafts and belt drives. During this process, the wood, which was fed to the grinder in pieces approximately 1.5 meters long, was shredded.

From 1921, electricity production was added to the wood pulp manufacturing. For this purpose, two water turbines were installed with a combined intake capacity of 14 cubic meters per second. The generated electricity is stepped up to 10,000 volts by a transformer station to then be fed into the VEW grid. Between 1921 and 1951, the hydroelectric power plant was leased to VEW Arnsberg.

From 1951, the wood pulp operation and power generation were managed in-house again. From 1956, the production of wood pulp was discontinued due to massive competitive pressure from Nordic countries. From that time on, electricity production was carried out exclusively, and the electricity generated was sold to VEW in accordance with a contract. The facility was modernized in 1983. The most important measure here was the conversion to oil-filled gearboxes instead of the old, highly failure-prone steel/wood gearboxes. This energy production represents the most environmentally friendly and continuous form of ecological electricity generation.

Furthermore, a metal goods production facility was added to the business from 1983. This includes the manufacture of chimney covers made of copper and stainless steel and the production of weather vanes and spire ornaments made of brass, copper, stainless steel, or zinc.

These products can be purchased directly from the factory here.

 

Manufacturing of chimney covers since 1983
When manufacturing a chimney cover, it is first important to know which material should or may be used.

If the house on which the chimney cover is to be installed has a zinc roof gutter, it is not advisable to manufacture the chimney cover from copper. Over time, a chemical reaction would destroy the zinc gutter. Therefore, in this case, the chimney cover should be made of stainless steel. A stainless steel chimney cover is an absolutely high-quality product that never rusts or corrodes.

If your house, on which the chimney cover is to be placed, has a copper roof gutter, the chimney cover can be made of either copper or stainless steel. The chimney cover is custom-made for the size of your chimney. We automatically manufacture the chimney cover approximately 5–7 cm larger per side than the chimney head. This ensures that moisture dripping from the chimney cover does not land on the chimney head.

Then, the thickness of the material from which the chimney cover is made is determined. In most cases, it is sufficient to opt for a thickness of 1 mm. Only if the chimney cover is particularly large or exposed to particularly strong winds can the material thickness for the production of the chimney cover also be chosen at 1.5 mm.

To ensure that the chimney cover is also particularly stable, we incorporate a bead on each of the two curved sides for reinforcement. On the long sides of the chimney cover, a 1 cm edge fold is made in each case. These two measures give the chimney cover particular strength.

Round stainless steel bolts (for a copper chimney cover, these are painted copper-colored) are used to mount the chimney cover. These round bolts are included in the scope of delivery of the chimney cover and are bent by us individually for your chimney cover.

Manufacturing of Weather Vanes
With the television report below and the photos of the production, you can get an impression of how our weather vanes are made. Other companies from Meschede-Freienohl and Arnsberg-Oeventrop are involved in our stainless steel weather vanes.

We also manufacture weather vanes and weathercocks for churches

Our family business has been relying on hydroelectric power since 1871. At our location in Meschede-Freienohl, we produce clean energy and also utilize it ourselves.
