Versatile special know-how in plant construction
DORNIER has been active in the design and construction of specialty machinery since it was founded in 1950. Alongside weaving machine construction, experiments were made with further products such as tenter frames and cardboard dryers during this early phase.
Based on the tenter frames, in the beginning development led to film stretching plants, initially for film production for the movie and photographic film industry, and then later until today for various types of packaging films. Mechanical tenter clips which can bear cross loads up to 3,500 N stretch films in longitudinal and transverse direction to a minimum thickness of 0,8 µm. With temperatures up to 280°C a production rates up to 30 km/hour can be attained.
A further product for the textile industry, the textile finishing machines for tubular knit-wear fabrics, was also developed based on tender frames and the know-how in fluid dynamics of the former aircraft engineers. Knit-wear fabrics which had to be cut open earlier for the finishing treatment can be now thermally fixed, mercerized and singed thanks to the patented circular expander.
Finally, drying plants for paper, cardboard, building materials, granulate and others have been part of the Lindauer DORNIER GmbH production program since 1952. Latest developments in this field allow the drying, heating and pasteurisation by means of microwave technology.
Today, these three product groups are bound together under the term specialty machinery and alongside the weaving machines form an important mainstay for the Lindauer DORNIER GmbH.
Up-to-date with custom-made systems
Photo and X-ray films, graphic films, electric insulation, special film for technical applications, condenser films, packaging films and audio and video as well as computer tapes. All these materials represent the DORNIER technology.
High product quality and low energy consumption
Many products require one-off drying during the manufacturing process or heat treatment before they are ready for use. For this, DORNIER dryers with a evaporative capacity of 20 t/h, 12 decks and a width of 4 m are an optimum tool.
Finishing circular knitted goods with the patented circular expander
Tubular singeing, bleaching and mercerizing have become standard pre-treatment processes to meet the high quality demands for knitted goods. DORNIER first presented a mercerizing machine for circular knitted goods in 1979.
