To meet market-driven quality requirements for (coated) textiles, manufacturers perform basis-weight measurement. The M-Ray technology of Hammer-IMS is available as part of Marveloc 602 single-sensor products or integrated into Marveloc-CURTAIN or Marveloc 602-CUBE turnkey systems.
The Marveloc-CURTAIN solution measures material up to 30 centimeters thick, and uses one or more fixed or traveling sensors for maximum coverage in cross-machine direction. The Marveloc 602-CUBE is a compact solution for fixed-point inline measurement of a range of materials including fabrics. The basis-weight measuring solution verifies material grammage (up to 1 gsm) uniformity to detect local anomalous regions with out-of-spec densities. The solutions of Hammer-IMS are fit to measure a wide range of (coated) fabrics used for applications in transportation, protective clothing, industrial roofing, awnings and canopies, furniture and seating, etc.

Textile manufacturing is a major industry. As textiles are often coated it makes sense to consult the global coated fabrics market. According to Markets and Markets, the global coated fabrics market is looking forward to an annual growth rate of more than 4%.
Textile manufacturing converts fibre into yarn, and yarn into fabric. These are then dyed or printed, fabricated into clothes. Different types of fibre are used to produce yarn. Cotton remains the most important natural fibre, followed by flax, jute, hemp as well as bast and leaf fibres. Also protein fibres (wool, silk) and synthetic fibres are widely applied. There are many variable processes available at the spinning and fabric-forming stages coupled with the complexities of the finishing and colouration processes to the production of a wide ranges of products.
The weaving process uses a loom. The lengthway threads are known as the warp, and the crossway threads are known as the weft. The warp is presented to the loom on a warp beam. The weft passes across the loom in a shuttle, that carries the yarn on a pirn.
Knitting by machine is done in two different ways: warp and weft. Weft knitting is similar in method to hand knitting with stitches all connected to each other horizontally. In a warp knit there are many pieces of yarn and there are vertical chains, zigzagged together by crossing the cotton yarn.
Textiles are often coated to obtain composites, consisting of a flexible substrate and a polymeric coating. The coating may be on one side, or on both sides with the same or a different polymeric coating per side.
Our CURTAIN integrates our M-Ray technology enabling full-industrial solutions. CURTAINs are tailored to perform a 24/7 industrial measurement task. Each CURTAIN machine consists our innovative Marveloc 602 measuring device. The CURTAIN itself is basically a rigid metal frame that support high measurement reliability and robustness. The rigidity of the frame guarantees robust measurements even in harsh environments. The Marveloc 602 sensors in the CURTAIN system measure through the material, with the transmitter of the sensor positioned above the measured material and the receiver underneath. The M-Ray technology and CURTAIN’s respectable gap height support high measurement standoff, avoiding scratches and defects on the material.
In addition to a range of in-line solutions, Hammer-IMS offers thickness and basis-weight measuring systems for laboratory use. Typically, lab systems consist of a single fixed measurement head, optionally equipped with a feeder and/or scanner. The incorporated M-Ray measurement technology is non-radioactive and non-nuclear, so no increased safety precautions or legal restrictions apply for your lab environment. In-depth measurements from within a lab-environment are typically performed for purposes of: production process optimization; when developing new materials such as nonwovens, plastics or coatings, ...; to investigate used specimens to draw conclusions about endurance, wear and material stability.
The CURTAIN C-frame system, displayed on the right, uses a 100% classic scanning C-frame concept. Its design is sleek and slim. The system can be equipped with one or more measuring heads. The system brings the power of multi-head to classic C-frame measuring technology. The pure electronic nature of the M-Ray technology within this fixed or scanning frame is non-nuclear and non-radioactive. The M-Rays’ high dynamics allow for high-standoff measurements that are fast and accurate. C-frame CURTAIN systems are available with arm lengths up to 1.5 meter. Such systems are extremely flexible because they can simply be inserted on either side of a production line without interrupting production. C-frame type systems can be used on lines of any material width.
