Measurement of Speed Differences in the Headbox of a Paper Machine

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!

SLM System measures precision tubes up to 2m

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 …

Calibrateable Cable Length Measurement up to 1,600 m/min

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 …
