Abstract

Buckle folding machine including folding pockets, which have a paper stop each. One folding pocket being for collection and subsequent joint folding of a plurality of sheets. From the folding pocket the collected sheets of paper pass together through a folding mechanism, having a draw-in point formed by upper and lower draw-in rollers and having at least one pair of folding rollers forming a folding point. A sheet feeder with a conveyor track directed toward the draw-in point, in which a stacking ramp is located, is arranged in front of the draw-in point. To guarantee trouble-free operation even when the intake depth is smaller than the greatest sheet size, an additional sheet drive, which partially conveys the newly arriving sheet through the draw-in point into a collecting folding pocket arranged behind it in a position in which it is lifted off from the conveyor track or from the sheets deposited in the conveyor track behind the stacking ramp, is arranged between the draw-in point, which is provided with an open passage gap, and the stacking ramp at a vertically spaced location above the conveyor track.
