LEONBERG - Dyeing and finishing specialist Brückner will showcase its well-known delivery program which includes almost all types of dryers, thermofusion and heat-setting ovens with mainly convective heat transfer, as well as the latest trends in machinery technology and the related process technology at next month's INDEX exhibition.
Over the last few years, Brückner has developed a number of very challenging projects in the nonwovens industry. These include lines for the heat-setting of geotextiles, finishing lines for nonwovens in the medical technology as well as thermofusion lines for the bonding of voluminous nonwovens for the furniture industry.
The Supra Flow BX double-belt thermofusion oven, for example, includes a rotary longitudinal cutter, guillotine cross cutter and semi-automatic winder for the production of voluminous nonwovens for the furniture industry.
With the double belt furnace Supra-Flow BX, Brückner's engineers have succeeded in achieving not only an increase in efficiency, but also the re-construction of the air circulation with fewer individual parts.
The oven is suitable for the production of high-loft nonwovens, medium as well as highly compressed fibre boards made of natural, synthetic and/or recycled fibres. It is a convective oven system which works according to the air-through principle. In each compartment the flow direction can be individually adjusted according to the product requirement. In most cases the basic material beside the matrix fibres are binding fibres melting at low temperatures such as bi-component fibres (PES/CoPES, PP/PR) and PP. Thermoplastic or duroplastic powders can be used also as binders.
The Supra-Flow BX is said to be particularly suitable for products with a higher weight, thickness and/or density and relatively high pressure losses during the flow through the product. The following processes can be implemented on the system: Thermofusion (for bonding PP, PET/CoPET, PP/PE), heat-setting and drying. The Supra-Flow BX is of particular interest to manufacturers of mattresses, duvets, inserts, insulation, furniture (upholstery, cushions), cleaning (dry and wet wipes, painter's cover foils), automotive components (headliners, thermal insulation, noise insulation, seat covers), thermal and acoustic insulation in the construction industry and carrier materials (floor coverings, technical coatings).
As well as the current sales successes, the continuous further development of the processes and the associated line technology play a decisive role for the German market leader. The basis of each Brückner line is the technologically best possible line configuration, which is always individually tailored to the customer's needs. For this purpose, customers and interested potential customers can carry out tests at Brückner's Technology Center at any time.
Heat-setting, thermofusion, coating, laminating, drying and finishing tests can be carried out on two lines in production scale.
In order to provide even better support in the future, especially for customers in the nonwovens production sector, a flow-through belt oven was added to the range of test machines at the Technology Center at the beginning of the year.
This is a small and compact thermo treatment line which, due to its short length, is excellently suitable to simulate also fast running processes with short dwell times at moderate test speeds.
The electrically heated unit is equipped with all relevant sensors for measuring the local system pressures, the air volumes, the air temperatures, the material surface temperature and the process air humidity.
