The Schleiper Hammer is located in the area of the town of Kierspe in the Schleipetal, a right tributary valley of the Volme . It has been included in the list of architectural monuments in Kierspe since March 14, 1989 and listed there under the serial number 45. The Schleiper Hammer is one of the technical monuments in the Märkisches Kreis.
In the possession of the Heimatverein since 1989 , a museum is being set up in the building , which will present the tradition of forging in the upper Volmetal in the 1930s. In a second section, the beginning of the Bakelite press is presented. This production has also been in the upper Volmetal, u. a. also developed in the Schleiper Hammer.
In the forging department, spring and drop hammers as well as trimming shears are ready to use , which work through a turbine-driven transmission or electric drive. In the locksmith's shop are also set up: a band saw, a universal milling machine , a slotting machine , a long planing machine , punching machines and a lathe . In the Bakelite department there are hand-operated and motor-driven toggle presses , a hydraulic press , a deburring and grinding shop . Individual parts are pressed for demonstration. A collection of tools and Bakelite products is under construction.
It was first mentioned in writing in 1815. The Schriever brothers bought the company and only five years later built a stately home nearby, the Reidemeisterhaus Schriever, which impressively represents the tradition and importance of the hammer mill owners on site. The original age of the hammer cannot be given. However, it has been handed down that the ruins of an ironworks came to light on the site of the upper operating pond when excavating . Iron smelting played a major role in the upper Volme area since the 13th century. With the introduction of water-driven blowers, smelting furnaces were built almost everywhere on the streams, in which liquid pig iron was extracted, which was refined into wrought iron in a further process . For this iron, the Osemund , the Brandenburg Sauerland became known far beyond its borders. In the upper part of the valley there are the remains of another ironworks and two Osemund hammers.
In the 19th century, with the introduction of new technologies, these hammer mills could no longer exist. A part was given up, a part could continue to exist through the conversion to the wide goods forge. Width goods are z. B. spades , shovels , hoes , beet lifters.
With the construction of the railway in the upper Volmetal , the hammer mill got a boost due to its proximity to the railway. A 25 hp turbine replaced the waterwheel , and the building has since been expanded in a series of small construction phases to form a factory in which all the work processes for manufacturing the width goods could be brought together under one roof. The installation of the transmission and the installation of a locomobile , which was switched on when the water power was no longer sufficient, made this decisive step in the development of a factory possible. From the 1930s onwards, other factories had been operating in the small factory. The plastics factory Potthoff, which is opposite today, was founded here as a screw factory. The same applies to the company Grote & Brocksieper, which produced tools here. The Schröder and de Graat companies opened a Bakelite press shop. They are an example of the fact that a water hammer and Bakelite press can form a unit. The medium-sized businesses in Volmetal have all developed from such small beginnings.
With its location in the Seitenbach valley of the Volme and its two operational ponds, the Schleiper Hammer represents an important period of iron production and iron processing that shaped the lives of the residents for centuries. Water, iron ores and the beech / oak forests formed the location factors for this. Even today, water power is used to drive the turbine. The electricity generated is fed into the public grid.
