Case Study: Sensor Operating in Adverse Conditions for Paper Machines
a day and stoppages and breakages are very costly. Within the machine it is important to control the position of the tape carrying the drying pulp across the rollers which are spinning fast. If the tape slides across the rollers it can be damaged resulting in complete replacement and long stoppages

Automated foundry fights foreign competition
. A steel-slat conveyor carries the molds through a drying oven and, after setting cores, automated handling equipment precisely closes the mold halves to ensure accurate parting-line fit-up. Conveyors transport the finished molds to the pouring area where they are filled with molten metal and, when cool

Getting value from an upgrade
. No major developments were made on the paper line except changing the drive system, including infrared drying with profile control and the headbox in the early nineties. Control systems were also upgraded from time to time. So, the initial paper machine consisting of a fourdrinier forming table
