Abstract: This invention relates to an apparatus for folding and creasing a sheet of material, comprising rotatable drum means for receiving said sheet on its periphery, A PAIR OF DRIVABLE NIP ROLLERS ON AXES PARALLEL TO THE DRUM AXIS, FOR FEEDING THE SHEET ONTO THE DRUM WHILE THE LATTER IS BEING ROTATED, SAID ROLLERS BEING PIVOTAL PARALLEL TO THEIR AXES TO BRING EACH, ONE AT A TIME, INTO DRIVING CONTACT WITH THE DRUM, A SCANNING ELEMENT FOR THE LEADING EDGE OF THE MATERIAL ON THE DRUM MEANS, AND CONTROL MEANS, ACTUATED BY SAID SCANNING ELEMENT, TO STOP THE DRUM, SO TO PIVOT THE FEED ROLLERS THAT ONE OF THEM WHOSE SURFACE ADJACENT THE DRUM HAS BEEN ROTATING IN THE OPPOSITE DIRECTION TO THE DRUM NOW MAKES DRIVING CONTACT WITH THE DRUM TO DRIVE IT IN THE SAID OPPOSITE DIRECTION, WHEREBY THE MATERIAL IS FOLDED AND PASSES FOR CREASING BETWEEN THE DRIVING FEED ROLLER AND THE DRUM MEANS, AND THEN SO TO PIVOT THE FEED ROLLERS THAT THE OTHER OF THEM DRIVES THE DRUM IN ITS ORIGINAL DIRECTION WHEREBY THE MATERIAL IS AGAIN FOLDED AND PASSES FOR FURTHER CREASING BETWEEN THE NOW DRIVING FEED ROLLER AND THE DRUM.
