Bernauer Group invests in Bruckner stenter line

Textilwerke Todtnau Bernauer KG, a leading producer and supplier of innovative and high quality fabrics, has announced that the company has invested in a tailor-made Bruckner stenter line for production of its Beratex fabric, which serves as release liner/textile for the production of tyres reducing on the long the process costs of the processing costs.
The Beratex fabric as such is woven of special polyethylene ribbons, made of a polyethylene film produced by the company itself. Depending on the quality it can be used up to more than 20 years without interruption. To increase the dimensional stability of this product, a heat-setting process is indispensable. Aiming at a further control and optimisation of the products, Hanspeter Bernauer, owner of Textilwerke Todtnau Bernauer KG, decided to integrate the final finishing of the fabric into the company. With the new heat-setting line made by Brückner, the company reached now 100 per cent value creating chain: from the granulate to the woven high-quality PE fabric and to the international marketing in more than 46 countries.
Textilwerke Todtnau Bernauer KG decided to buy a state-of-the-art Brückner stenter because only a line with the alternating arranged thermo zones, which is typical for Brückner machines, ensures the required temperature accuracy across the entire length and width of the dryer.
In the conceptual design of the line, the project team Bernauer & Brückner turned the highest possible attention on an accurate fabric flow of the rigid and thus delicate articles and an operation which is not interrupted by batch changes. Given the firmly installed unwinding unit with two positions a generously dimensioned fabric accumulator allows to connect the batch ends by sewing without interrupting the production process.
An automatic width control of the entering fabric controls the centred entry into the stenter and protects the transport system from critical mechanical loads. The use of sensitive traction measurement systems for an accurate tension control between the individual draw rollers and sophisticated tension control software prevent too high fabric tensions in each individual production step.
Another fabric accumulator with following two-position winder is located at the stenter exit and allows changing the batches without machine downtime. This optimised installation makes it in addition possible to operate the line with a minimum number of operators and increases thus the economic efficiency of the line. The service personnel which never before had worked with a stenter, was trained during the start-up period as machine operators. After two weeks, already they were able to handle this complex machine and finish technically sophisticated fabric. (GK)
