Length measurement “calibratable” acc. to MID 2014/32/EU in cable production Cables are sold by length and must be measured with calibrated length measurement systems if the sale takes place within or into the EU. Larger cable diameters with solid and gripping insulation can be measured up to a certain speed, if necessary, still well by … Weiterlesen …
Where do the discrepancies between purchase length and sales length come from? Films are purchased as roll products, processed and sold again as roll products. However, there are often differences between the length of purchased materials and the length of finished products. The reasons for this are manifold. Analyzing them is the key to increasing … Weiterlesen …
Under- or Over-Stow? Measurement technology for the paper industry … Every papermaker works with the jet-screen ratio to influence significant quality parameters of the paper. Among others, these are: the longitudinal/cross ratio, the formation, the tensile stiffness orientation and thus also strength properties such as the flat crush resistance, the strip crush resistance or the … Weiterlesen …
The task was to measure high-gloss black lacquer foil, metallized foil and immediately afterwards a highly transparent foil correctly to length. Brilliantly solved with the ELOVIS laser encoder µSPEED. The result: 1 % overproduction avoided. That is 600 running meters x 2 m web width per production day – equivalent to 1200 m² per day. … Weiterlesen …
The paper quality is often already determined in the headbox of a paper machine. The appropriate ratio between wire speed and jet beam velocity must be maintained, but the pulp jet velocity should be as homogeneous as possible within the headbox. Therefore, there should be no or only very small speed differences. It is not easy to ensure this and it is not possible to check speed differences with tactile measuring equipment. µSPEED laser encoder systems work contactless and are even suitable for this measuring application, so for measuring differences between paper wire and stock steel or within the headbox. Therefore µSPEED systems are an important tool for trouble shooting in paper production!
The Czech Institute for Metrology CMI has recently granted MID 2014/32 / EU approval for a cable measuring machine based on the laser encoder μSPEED-PRO and the counter MID-COUNTER. The cable length measuring machine is designed for cable diameters from 8mm to 60mm. The length measuring machine is part of a cable rewinder from Cabmat.
Weerth-Handling-Systeme GmbH has developed a machine for chip-free and burr-free cutting of precision tubes with diameters from 8 mm to 60 mm and lengths from 70 mm to 2,000 mm. For self-monitoring purposes, the machine is equipped with the SLM length-section light scanner for discrete part length measurement. As the tubes pass through, they are … Weiterlesen …
Another milestone in the product range of SLM discrete part length measurement systems has been reached. SLM now measures the length o transparent, optical film format sheets with high precision. A first line was taken by a well-known manufacturer of optical film for displays and monitors with flying colors. One day on the spot to … Weiterlesen …
Thanks to the laser encoder μSPEED, submarine cables of the correct length are picked up on land with several ships worldwide and deployed on the high seas. It’s about cable lengths of several hundred kilometers. If the loaded length is not correct, this can not be corrected at sea. The ELOVIS systems work with high … Weiterlesen …
The combination of μSPEED-SMART laser encoder and MID-COUNTER together with the CGS cable guide with measurement tripod has recently been successfully tested at cable speeds of up to 1,600 m/min. The high-speed extrusion line delivered cable diameters of 0.5mm to 6mm. The cable routing would theoretically be suitable for diameters up to more than 10 … Weiterlesen …
