For 70 years, Brückner has been the worldwide partner for all companies which are drying, coating and finishing web-shaped materials: whether clothing fabrics, nonwovens, carpet, glass or coatings - the variety of materials to be processed has never been limited. Today, it is no longer just a question of machines, but rather of automation and control systems. The topic of digitization and Industry 4.0 opens up completely new possibilities for increasing productivity, reducing the use of resources and improving quality. Intelligent assistance systems monitor the machine settings in the background and provide the machine operator with information on how to run the system even more productively and consuming less resources. Studies have shown that optimizing production parameters can increase production speed by up to 40 percent and/or reduce energy consumption by up to 30 percent.
A newly developed simulation tool helps to optimize existing recipes. The many machine parameters to be set have been reduced to the essentials and can in future be calculated automatically on the ba-sis of the textile key data.

Directly connected with the customer
For the service, there is a new maintenance tool that proactively gives the machine operator or maintenance department service instructions that can be tracked in a logbook. In future, a newly de-veloped online service platform will support our customers with all service inquiries. The technicians communicate directly with the customer via video conferencing - partly with augmented reality. Doc-uments such as circuit diagrams or maintenance manuals can be viewed and explained together and spare parts can be ordered directly. For regular maintenance processes, photo or video illustrations can be stored in local language. The exchange of machine data with higher-level control station or ERP systems is easily possible with OPC-UA. This allows to rationalize processes in the textile factory and to monitor the quality.

Integrated finishing lines
Brückner offers in the denim sector integrated finishing systems for pigment dyeing, synthetic resin finishing and coating: All components from the entry area, padder, IR pre-dryer, minimum application unit, coating unit, stenter, curing / hotflue, cooling, to the exit area are available. In the field of continuous dyeing new concepts will be presented. The continuously improved Power-Infratherm IR pre-dryer has heating and cooling times of less than 5 seconds. The stripe-free drying burner segments made of special metal fiber and the large temperature control range ensure the con-sistent and reproducible high fabric quality.

Uniform drying
The Power-Colortherm Hotflue ensures uniform drying of the fabric over the entire width of the cham-bers. Even with narrow fabric webs on a wider machine, the dyeing results are optimal. Due to the symmetrical design and the inverter-controlled fans, the uniform air distribution through the upper and lower nozzles makes a volume adjustment via mechanical flaps superfluous. Optionally available are patented, driven special spreading rollers for crease-free operation with sensitive fabrics (stripe satin / percale / weft-elastic fabric) as well as a highly effective, fully automatic roller cleaning system.

Multi-layer stenters
Multi-layer stenters are mostly used where little space is available. They are suitable for finishing wo-ven or dimensionally stable knitted fabric, nonwovens, needle felt, technical textiles or for the wool industry. With the new Power Frame VNE multi-layer stenter, only one machine operator is required, as the entry and the exit are on the same machine side. This applies both to the version with two and with six fabric passages. The new VNE machine concept offers the highest possible power density on a small floor space or a long air flow section in a very confined space. The dryer itself is equipped with the patented split-flow air circulation system and the alternating arrangement in each half compart-ment additionally ensures optimum and uniform air circulation and thermal treatment of the fabric.
