METHOD AND APPARATUS FOR FORMING UNIFORM STACKS OF UNEQUAL, SUBSTANTIALLY FLAT OBJECTS

摘要

The invention relates to a method for forming uniform stacks (2) of unequal flat objects.(3) The method comprises the steps of feeding the objects, stacking the supplied objects onto each other in two equal part-stacks, transporting the part-stacks to a combining location and combining the part-stacks into a uniform stack at this location, wherein during the transport one of the part-stacks is separated off, rotated through a determined angle and once again transported further. The invention also relates to an apparatus (1)for performing the method, comprising means (4) for feeding the objects,(3) means (5) for stacking the supplied objects onto each other in two equal part-stacks, means (16) for transporting the part-stacks to a combining location, means (7, 20) for combining the part-stacks into a uniform stack (2) at this location, and means (7) arranged between the first stacking means and the combining location for separating one of the part-stacks from the transport means, rotating said part-stack through a determined angle and feeding said part-stack back again to the transport means.
