• a frame,
• a paper-feeder,
• a first pair of motorized, substantially adjacent rollers supported at a delivery end of the paper-feeder about respective parallel axes to draw sheets of paper from the feeder, one roller of the first pair being mounted on a first support adjustable in position to change the distance between the rollers of the first pair,
• a folding buckle arranged to receive a sheet from the first pair of rollers through an inlet mouth, and having a barrier causing the sheets to stop and to bend into the shape of a groove below the inlet mouth,
• a second pair of motorized, substantially adjacent rollers supported near the inlet mouth about respective parallel axes to pinch the groove and to make a transverse fold on the sheet, one roller of the second pair being mounted on a second support adjustable in position to change the distance between the rollers of the second pair, characterized in that it comprises at least one transverse beam to follow changes in position of a respective one of the first support and second supports, and is arranged to guide the sheet near the inlet mouth.
