Abstract
A sheet feeder having parallel opposing shafts with rollers or belts for engaging sheets. The sheet feeder having one control to adjust the height of both sides of one shaft so that the rollers apply the same force to both sides of the sheet to feed the sheet straight preventing the sheets from jamming in the sheet feeder. The sheet feeder can have manual or electronic height adjustments. The gap between the shafts can be quickly and easily changed for quickly changing production runs with different thickness product. The shafts are three-piece shafts for ease of changing the rollers on the shaft. All the bearings are pregreased and sealed to protect the bearings from dirt and debris. Rods connect the height adjustment on both sides of the shaft so both sides are adjusted by the same amount at the same time.
