Abstract: A sheet material feeder includes a sheet material holder for holding a pile of sheet material, a rotating drum for transporting the sheet material from the pile, and an acceleration device receiving the sheet material from the rotating drum at a first speed and releasing the sheet material at a second speed greater than the first speed. Also disclosed is a sheet material feeder with a sheet material holder for holding a pile of sheet material; and a rotating drum for transporting the sheet material from the pile, the rotating drum including at least one sucker rotating with the drum for contacting the sheet material.

Abstract: A sheet material feeder includes a sheet material holder for holding a pile of sheet material; a sucker bar device having at least one sucker for contacting the sheet material, the sucker bar device having a pivot axis, and an actuator for pivoting the sucker bar device about the pivot axis and having a first position and a second position. When the actuator is in the first position, the sucker pivoting about the pivot axis from a first angle where the sucker contacts the sheet material by a predetermined angle so that the sucker removes the sheet material from the pile; and when the actuator is in the second position, the sucker pivoting about the pivot axis from a second angle where the sucker does not contact the sheet material.
