A sheet feeder for separating and feeding the bottom sheet in a stack, a biased corrugating ramp being provided to provide a large corrugation in light weight papers for maximum feeder reliability. The corrugating ramp is adapted to be depressed by heavy weight, stiff sheets to allow the sheets to more closely approach the vacuum feed belts and assure adequate acquisition thereby.
