Abstract
A buckle folding machine is provided with a device with which the folding rollers (W through W ) can be automatically set to different folding gap widths as a function of the measured or calculated thickness of a sheet of paper or stack passing through the folding gap (F through F ). The folding rollers to be adjusted are mounted on pivoted levers ( ), which are mounted coaxially in pairs and which be pivoted against permanent restoring forces under the effect of electrically controllable adjusting members (S through S ). The adjusting members are actuated by an electronic process computer, which calculates the folding gap widths to be set in the particular case according to a preset working program from measured and/or manually entered paper thicknesses or stack thicknesses and/or fold types. The adjusting members (S through S ) comprise a plurality of pneumatic working cylinders, which are arranged in a row in a cascade-like pattern, and whose working strokes mutually add up. The setting of the folding rollers can thus be performed very rapidly and also temporarily for even a short duration.
