measurement during material movement, cross to the feeding direction
Widths of webs, tapes and plates are usually measured by hand in random sample inspections because contact measurement devices damage the products or because non-contact measurement devices are too costly. … In the production of webs, belts and plates, the edge trimming and the lengthswise cutters are adjusted at the beginning of the process. This is followed by a manual control of the width. In the ongoing manufacturing process, dimensions are generally no longer checked. A check can only be done again on the finished product, the roll of material or the plate. If deviations occur, the entire roll or a batch is declared as a waste. … The solution is a non-contact gauge that is easy to integrate and does not disrupt the regular production process. ELOVIS offers the µMETER-X systems for the measurement of webs, tapes and plates with widths up to the current 2000 mm and with an accuracy in the 1/10 millimeter range. The non-contact measurement is carried out by the µMETER-X gauge during the product cycle in cross feeding direction. The measurement is used for production optimization as well as for sending an error message in case of exceeding production tolerances and it is used for the documentation of the production quality. µMETER-X gauges are maintenance-free, permanently accurate and measure widely independent of material. µMETER-X gauges are used to measure the width of webs, tapes, plates, sheets, blanks, bolts, bars, beams or packages made of a wide variety of materials.
Typical measurement objects using non-contact width measurement:
Plates, boards, formats, such as:
- plastic sheets and foil formats
- metal (sheets, blanks, bows, …)
- construction and insulation materials (plasterboard and fiberboard, …)
- wood (firewood, KVH, beams, …)
- chipboards (MDF boards, HDF boards, OSB boards)
- furniture panels (MFB melamine-coated panels, printed panels, lacquered furniture panels, …)
- floor coverings, tiles, carpet tiles
Webs, tapes, strips and ribbons, such as:
- bituminous membranes, roofing membranes
- paper, cardboard, packaging webs
- foils, printed / unprinted, made of plastic, aluminum, composite material
- textile, non-woven, fleece, felt
- separator foils, battery foils
- strippings
Typical production machines that can be optimized with a width measurement:
Machines for the production of plate goods:
- guillotine, sheeter, cross divider
- cutting machine, sawing line
- flying saw, continuous saw
- punch, dividing line, trimming line
Machines for the production of web products and tapes:
- slitter, sheeter
- winding machines, rewinders
- slitter
- fabric inspection machine
- calendering machines
- laminating machines
