KurzfassungA small German company has developed and patented a novel technology process that allows a more efficient production of helical screens used in the manufacturing of paper. They are seeking a machine manufacturer, ideally within the mechanical engineering industry, to build and further develop the existing prototype. The company is open for any kind of co-operation.
Helical screens (or spiral sieves) are used in the paper industry for the filtration of fibres out of the pulp slurry in the first stage of paper production.
Since 1980s there have been 3 different machines used for helical screens production: the first one is used for the winding of plastic wires into individual spirals; in the next step they have to be storaged before they are joined (left and right spirals) with the second machine. At the end, the third machine, so-called stuffing table, connects the spirals with fixing wires. This process is resources and time-consuming.
A German company developed an innovative technology process enabling the production of helical screens with only one machine. According to this technology the individual spirals are being winded (with winding heads) and inserted into each other in an overlapping way on a working platform. On this working platform spirals are being storaged before they are joined and stuffed together to the appropriate dimension. The single step are being operated by means of moveable joining devices and controlled with a software programme.
The production process of 144sqm of helical screen (spiral mesh) with the traditional technology requires 100 working hours of minimum 3 machines, which makes 33.3sqm/24h. The new processing method takes 12 working hours with the efficiency of 281 sqm/24h (estimated performance of machine with 16 widingheads simultaneously). Additionally, energy consumption is reduced by up to 50% and waste materials production decreases around 30%. More flexibility is also given.
The company is seeking a machine manufacturer to build a spiral assembling machine according to the specifications given. The partner should have experience in the precision and sensor technology and in electronic engineering. A prototype/testing device is available.
Technical Specifications / Specific technical requirements:
- Spiral assembling machine.
- Monofile (individual spirals): 0,4 - 1 mm (diameter).
- r.p.m. max. 5000.
- Spiral mesh: min. 6 - max. 12,5 m (width).
- Bearbeiten (Drehen, Bohren, Fräsen, Schneiden, Hobeln etc.)
- Sensor/Multisensortechnik, Instrumentierung
- Absolutely novel process
# Type of partner sought
