At speeds in excess of 500ppm, LONGFORD provides the most technically advanced and efficient feeders in the industry. Using speed following or trip compensation technology, the Microprocessor controlled feeders feed in exact synchronization as the line ramps up and down in speed. The feeders may be side or straddle mounted to the line and uses no vacuum, camshafts, chains or other exterior drive devices. This allows the feeder to be moved from line to line with ease, and therefore a better return on investment.
