Company profile Roth Composite Machinery GmbH
As medium-sized owner-managed company, Roth Composite Machinery GmbH resulted from the merger of the two affiliated companies of Roth Industries EHA Composite Machinery, Steffenberg, and Schlesinger Maschinenbau, Burgwald, in June 2016.
Within the scope of a reorganization, Roth Industries combines related business areas of the two fields building and industrial technologies and focuses the professional expertise on six divisions. By this, Roth Industries is changing from a group of companies with different trademarks to a homogenous unit with a brand image in one package. Basis and initiator is the business family Roth. All divisions are operated under the trademark Roth in future – it is the “face” of our family company and shows global identity.
Roth Composite Machinery represents the division Composite Technology and is an expert in the field of special machinery construction.
For over 50 years, the range of products comprises components, machinery and equipment for the manufacture of high-quality and particularly strong plastic products for light-weight applications by uisng the Filament Winding process, especially for the automotive and sports industries, the aerospace sector as well as for wind energy stations. By the mentioned machinery and equipment, synthetic or thermoplastic resin materials with reinforcing fibres, mainly glass or carbon fibres, are processed.
The company also plans, designs and manufactures complete production lines.
By using Prepreg Plants, semi-finished composite materials are produced. Due to the pre-impregnated (hence the name “Prepreg”), partly cured and thermoplastic matrixes, these materials can be processed to finished products in later working steps.
By the manufacture of Coating and Impregnation Lines for the processing and finishing of web-shaped products such as paper, foil, laminate and fabrics, Roth Composite Machinery offers tailor-made solutions according to customer’s specifications.
Pleating machines for filters are another segment in the product program. The produced filters are used in the automotive industry as well as in the areas aerospace, hydraulics, ventilation and medical technologies. This product range comprises mechanically and electronically controlled knife pleating machines as well as suitable peripheral systems.
For more than nine decades Roth Composite Machinery, Burgwald – previously known as Schlesinger Maschinenbau – manufactures plants for the production of brushes and brooms for household and industry applications. They started in 1919 with the production of a patented multiple-spindle brush wood drilling machine. There hardly is a country in this world where no machine from Burgwald is found.
