The drawing rollers arranged upstream of a pair of cutting cylinders in a folding apparatus are mounted with triple suspension on beam-type supports. One roller is stationary and the other roller is displaceable. The support bearing the roller is mounted in a three-point manner via joint rods consisting of threaded spindles with joint heads, the axial displacement of the support being blocked by a further, transversely arranged joint rod. By means of two pneumatic cylinders, the gap spacing and the pressing-on force between the rollers can be adjusted.
