The tried and true method of synchronizing the speed of multiple stations by linking them mechanically remains a popular option in machine design. This is still seen in printing presses, conveyors, roll forming and packaging lines, just to name a few examples. A customer of ours recently requested some assistance in designing a conveyor and feed system for a large pipe cutting operation. The long, heavy pipe was to be loaded on a set of rollers that would then move the pipe into a cutting house where it would be sawed into various lengths. The rollers were to be spaced several feet apart and required consistent speed to smoothly move the pipe along. There was also an acceleration/deceleration element to the prole, as motion would only commence after the pipe was loaded and stopped when th
