ABSTRACT:
A tucker folder having a pair of rotating folding rollers adjacent to which at least one other pair of similar folding rollers is located. The rotational centers of the rollers in these other pair of rollers has an arc of the same radius as that of the first pair. The folder of the tucker folder is equipped with means for alternating interaction between the tucker blades and the two pairs of the folding rollers to divide the newspapers emerging from the folder into separate streams. A cam controlling the operation of picking pins is capable of being shifted with respect to the spaces defined between the folding rollers, depending on the interaction between the tucker blades and the respective pair of the folding rollers, to form a transverse fold in the middle of the paper sheet, irrespective of the stream taking this sheet.
