ABSTRACT:
In a method and apparatus for withdrawing a selected number of consecutive copies of newspapers, for instance, from a series of said products travelling horizontally and arranged in overlapping formation (4), a gripper (10) in the form of a mechanical clamp is caused to engage with the desired number of copies by the front edge of the clamp being kept in contact with the formation along a selected distance, the clamp being driven with a speed difference in relation to the formation such that a selected number of copies enter the clamp along the selected distance. At the end of the distance the clamp is closed and its speed thereafter accelerated in relation to the formation, to a speed considerably higher than that of the formation, its direction deviating only marginally from the direction of movement of the formation. Only a few consecutive copies are withdrawn from the formation so that no gaps occur in the formation.
