VIU™ for Elastic & Light Rigid Tapes & Flat Cords

Automated Inspection of Elastic Tapes and Flat Cords

Automatic Inspection of Elastic Tapes & Flat Cords

If you are a manufacturer of high volume tapes, cords and other narrow elastic or rigid fabrics, and you need your product to be 100% inspected before it leaves the factory, you know it is almost impossible to perform this manually with the human eye. Not to speak of the inconsistency that comes with conventional visual inspection. Your aim: Always delivering high and consistent quality products for a competitive price. That calls for innovation and efficiency.

The COMVIS VIU™ for Elastic & Rigid Tapes & Flat Cords uses the proven vision technology of the VIU™ for Seatbelt to perform high-end automated inspection on narrow light rigid and elastic tapes and flat cords. The modular setup provides the possibility to either choose for a semi-automatic configuration which stops the defect on a small VIT (visual inspection table), or the fully automatic configuration with 1 or 2 label applicators which labels the defects on the fly. The new VIU™ comes standard in 2 widths: 5 – 25 mm tape width, or 25 to 70 mm tape witdh.

VIU™ with Label Applicator(s)

The basic VIU™ is semi-automatic. In other words, the defects stop on the small VIT (Visual Inspection Table). Here, an operator can cut out, fix or mark the defect. But of course, stopping the inspection system drastically decreases the average inspection speed and thus affects the optimum efficiency. Furthermore, an operator has to be present at the machine to act on a found defect, before it can proceed.

For that purpose, the basic VIU™ can be extended with one or even two label applicators to label the found defect(s) on the fly, without the need to stop or slow down the inspection system. Single defects or a group of defects are labelled with the use of one label applicator. A special label algorithm merges defects within the specified ‘minimum label distance’. A second label applicator can optionally be used to set a ‘minimum length of good material’ using 2 different colors of labels.

Our labels are specifically designed to be easily released from the backing material of the roll in the applicator, but on the other hand have optimal adhesion characteristics on woven cotton, elastane or (semi) poly materials. The stainless steel guiding plate below the applicator enables a fine adjustment, to precisely apply labels on the smallest fabric widths.

Easy operation via HMI

The complete VIU™ is operated via the user friendly HMI. Article settings from the Texplorer CORE™ inspection software can be selected from the Article tab on the HMI. Select your article, click on start and the inspection system is ready to go.

Furthermore, settings for materials, stopping distance and defect clustering can be adjusted. But also language settings and user authorization. Using different user authorization levels, you are able to prevent operators from adjusting higher level settings and leave those privileges to the quality manager.

Alarms and counters are displayed on the main screen. For instance, Knot detected, Doors opened, No tape detected, Safety switch activated, number of defects found and length of inspected tape.

Examples of materials

The VIU™ is suitable for automated inspection and the detection of defects in woven tape, herringbone tape, elastic webbing, braided tape, twill tape, suspender belt, cord ribbons, straps, grid band, mesh, raschel tape, warp knitted narrow fabric, elastic bands for lingerie, corsetry, swimwear, jacquard tapes (optionally) with a standard width between 5 and 70 mm.

Extraordinary inspection results

Using COMVIS Texplorer™ CORE, the industry’s most powerful and modular vision inspection software for woven, nonwoven, knitted and other (technical) textiles, the VIU™ is capable of finding the smallest deviations in your product. For example, weaving defects, knots, stains, filamentation or contamination. But you control the sensitivity! If for any reason specific deviations are considered as acceptable, just save your article settings with a more tolerant threshold.
