Verfahren und Vorrichtung zur Produktführung in einem Falzbildungsbereich eines Falzapparates

摘要

A sheet moving anti-clockwise on cylinder 8 has its central region inserted into a jaw 20 on folding cylinder 14, the gripped sheet then being withdrawn from cylinder 8 as cylinder 14 continues its clockwise motion, the withdrawal and guiding onto cylinder 14 being aided by element 11. Element 11 is fixed to a contoured mount 10 and comprises rows of staggered rollers (figure 8) or a substrate bearing bristles. The bristles may be inclined to the substrate in one direction in region 23, inclined to the substrate in an opposite direction in region 25, and perpendicular to the substrate in region 24. In transition zones 30 and 31, a mixture of inclined and perpendicular bristles is used.
