Abstract
An apparatus and a method for separating and aerating sheet material arranged in a stack include a support to receive the sheet material stack thereon before the same is separated and aerated. A roll mechanism clamps the sheet material stack between an upper rotatable roll and a lower drivable roll. The sheet material stack is conveyed into a position between the upper and lower rolls when the same are in an open position. A ram converges the upper and lower rolls to clamp the sheet material stack therebetween. A drive rotates the lower roll in the conveying direction of the sheet material stack, and a gripper selectively grips the front end of the sheet material stack.
