Abstract
An apparatus and method are provided for gathering flat articles ( ) into stacks ( ) by conveying stacks in production successively along a gathering route ( ) past feed stations. The stacks ( ) are conveyed on stack supports ( ) with supporting surfaces ( ). Leading edges ( ) of the articles ( ) to be added to the stacks are held by holding elements ( ) that move in a supply route ( ) that traverses the gathering route ( ) at the feed stations. Each article ( ) is inserted between successive stacks ( ) or stack supports ( ), with the leading edge ( ) being inserted first. The inserted article is released from its associated holding element ( ) and then positioned on the upstream or downstream stack ( ) or stack support ( ) by the force of gravity and/or by its own inertia, and the holding element ( ) is conveyed onwards in a downward direction.
