Abstract
Plates, leaves, foils or similar sheet material is led to a stack by a belt transporter, wherein a negative pressure holds the sheet to the moving belt. The source of negative pressure, such as a vacuum chamber, is continuously applied to the transport belt, but the negative pressure between the belt and the sheet is passively interrupted by the sheet itself, as the sheet is transported beyond a predetermined position. Once established, the predetermined position results in the sheets being deposited consistently on the stack.
