  • Publication number: 20080008509
    Abstract: A receiving module intended for a document processing line, which comprises a frame and at least one pair of supports which are bringable into a receiving position, wherein one or more document products can rest on the supports, and a releasing position, wherein document products are released by the supports for passage in downward direction, wherein the supports of a pair extend substantially in one plane and are arranged to be movable away from each other and towards each other in that plane for assuming the releasing position and the receiving position, wherein the supports are each provided with a bearing surface on which a lowermost document product rests in use, which bearing surface is designed such that, when the supports move away from each other, substantially no relative sliding movement occurs between the bearing surface and a lower side of the lowermost document product. The invention further relates to a stacker with such a receiving module and to a method for stacking document products.
