About this technology
Overview
When a printing press jams, damage is extensive, repairs are costly, and time and production loss can be expensive. James River Corporation requested G.W. Shelton, a design engineer with Logical Control Systems to solve this problem. Shelton found the solution in a NASA Tech Brief article describing a system of pulley and belt drives. This led to the design of a system that monitors drive components for changes in relative speed that would indicate belt slippage and jam probability. When a combination of variables is not met, an emergency stop" signal is sent to the press and an alarm is triggered."
