Abstract: The invention relates to a feed deflection apparatus for at least partially folded newspapers or magazines. A pair of arrester cylinders (1) and a pair of acceleration cylinders (2) are coplanar but at an angle of 90.degree. relative to each other. A paper subjected to compression by the tail between the pair of arrester cylinders (1) is stopped by decelerating the cylinders (1). At the moment said paper has stopped, the pair of acceleration cylinders (2) takes hold of the paper's edge and accelerates it to a new speed directed at an angle of 90.degree. relative to the previous direction. The apparatus can be used for assembling or disassembling piles of papers. A particularly practical application is feeding papers from a printing machine to an after-treatment trimmer.
