The apparatus for filing or ordering a scale flow of folded, flat printed products from a rotary printing press has sliding teeth formed into a filing comb arranged on both side of the scale flow and fixed to tooth supports and with, in each case, at least one sliding tooth engaging to the left and right of a printed product in the scale flow behind its fold. The tooth supports are fixed to rotatable chains arranged to the right and left of the scale flow. One drum runs laterally along side the scale flow, so that said engagement is permitted. An equal number of filing combs is fixed to the rotary chains and run in each case around two sprockets, at least one being a driving sprocket, the spacing of two teeth on the same rotary chain determining the new scale spacing. The driving sprockets are controlled synchronously to one another with a single rotary speed, so that between the sliding teeth and the running scale flow a speed difference is obtained permitting a displacement of the printed product within the scale flow. The printed product displacement leads to a reduction of the spread or scatter of the scale spacing.
An apparatus for adjusting the relative positions of like portions of elements in a scale flow of flat, folded products moving in a predetermined direction comprising the combination of
A method of controlling the operation of an apparatus for adjusting the spacing between like portions of elements in a scale flow of flat, folded products wherein the products are placed in the scale flow with spacings of the like portions deviating from a predetermined spacing pattern and are moving in a predetermined direction, the apparatus being of the type comprising first and second sets of equal numbers of shift blades on opposite sides of the scale flow, and first and second means for movably supporting the shift blades of the first and second sets, respectively, such that the blades in each set are longitudinally spaced apart relative to the direction of scale flow and individual ones of the blades are opposite each other and operate in pairs, each said means including a support for each shift blade for moving its supported blade longitudinally along the scale flow such that pairs of the blades can engage and longitudinally shift an individual product, and drive means for driving said support at a selected longitudinal speed different from the speed of movement of said scale flow, the method comprising
