Improved quality and productivity with textile straightening systems

Today, manufacturers and users of textile production systems face ever-increasing demands in terms of production speeds. Quality must be ensured, while the number of rejects and any machine down time must be kept to a bare minimum.

Textile webs typically pass through a wide range of different production processes. Weft distortion is caused primarily by transport through the various wet processes. Correction of any distortion before processes such as drying, heat setting, coating or printing is absolutely essential. Erhardt+Leimer straightening systems make sure to keep textile webs are free of weft distortions.

Pick and course counter system ELCOUNT

ELCOUNT is a system to determine and control the thread density in knitted and woven fabrics. The operator traditionally effects this process occasionally by punching a sample of the fabric at the end of the relevant finishing process. With the ELCOUNT system, every meter of the fabric is checked and adjusted to the desired density (and consequently the desired weight) without touching the fabric and without slowing down production; this guarantees uniform and constant fabric quality even during night shifts.

Also the ELCOUNT uses highly sophisticated, non-contact matrix cameras for scanning the fabric. Typically, the system is used in stenter, sanforizing and compacting processes and can be supplied only for monitoring or for automatic adjustment with a closed control loop. Furthermore, a lab version is available so that manual density counting can be eliminated. It is possible to transfer the desired fabric density directly from the lab to the finishing machinery where the ELCOUNT system is installed. Contrary to other density/weight measuring systems the ELCOUNT works even with wet/moist fabrics. Thanks to its recipe and report facilities, constant quality can be ensured and proven at any time.
