Technical textiles have become indispensable in many industrial sectors. Straightening and control technology is important for their faultless and efficient production. Mahlo GmbH + Co. KG, Saal/Germany will be exhibiting excerpts from their portfolio of modular systems and innovative solutions.

The systems presented are geared to the needs of manufacturers of technical textiles e.g. the Famacont PMC-15 thread counter in live operation. The system measures the thread or knit density by means of a sensor on the running web and compares it with the nominal value stored in the recipe data management. The detected deviation of the thread density from the nominal value is used to fully automatically regulate the over-feed during the pinning process on the tenter. For measurement, the machine uses continuous opto-electronic scanning with transmitted or incident light or imaging with a camera. Depending on the fabric speed and fabric type, the opto-electronic TK sensor can detect up to 220 threads/cm, the camera sensors CK and CK HF up to 270 threads/cm depending on the design.
Also on display is a model of the Orthopac CRVMC-12 automatic straightener. The machine with its modular design allows large working widths of up to 5,400 mm with high tensile stress at the same time. This makes it very suitable for technical textiles, glass fabrics and woven or tufted carpets. Another special feature is that the bow rollers are only swung into the fabric when required and produce a very uniform straightening effect. If there is no bow distortion, the rollers are in neutral position without touching the fabric.
However, Mahlo's range not only includes solutions for straightening distorted fabrics, but also for controlling the basis weight with beta or x-ray technology, the thickness with laser and shadowing, the moisture with infraded or microwave, as well as air permeability. With all sensors, a high measurement accuracy is pivotal for an optimal measurement result. The measured data are the base for an automatic process control and thus the prerequisite for a perfect web with narrow tolerance.
