  • an operator can move the individual folding pockets quickly and easily and, moreover, clamp them easily, which considerably simplifies machine operation and can be carried out in a time-saving manner.
  • the guide elements can be rotatably mounted on one frame part of guide rollers which are in guide engagement with longitudinal guide grooves near the edge in the upper and lower surfaces of the folding pocket.
  • the clamping device can engage in the longitudinal groove for clamping against the inside of one frame part or perpendicular to the plane of the folding pocket.
  • a tab fastened on the inside of the one frame part can also be provided, which is in guide engagement with the aid of a guide projection with a longitudinal guide groove on the upper and / or lower surface of the folding pocket.
  • the guide elements on the one frame part can be rotatably mounted rollers, in the circumferential surface of which there is a circumferential groove is formed with which a guide rail fixed on one longitudinal side of the folding pocket is in guide engagement with its narrow upper and / or lower side, which respectively protrude above the upper and lower surface of the folding pocket.
  • the clamping device can engage on the guide rail for clamping against the inside of one frame part or perpendicular to the plane of the folding pocket.
  • a tab fastened on the inside of the one frame part can also be provided as the guide element, which in this case has a guide recess with which a narrow projecting side of the guide rail is in guide engagement.
  • Locking bolts mounted on one frame part and axially adjustable from the outside thereof can be brought into locking engagement with locking bores provided in the guide rails.
  • recesses can be provided in the guide rails, which allow the folding pocket to be moved laterally in the position of association with the guide rollers.
  • the device associated with the other long side of each folding pocket for locking the folding pocket on the inside of the other frame part expediently has an axle mounted in both frame parts, on which a clamping lever is held on the outside of one frame part and which carries an eccentric on the other frame part, which is guided through a bracket carrying a tensioning block in such a way that when the clamping lever is pivoted the clamping block presses the folding pocket against a pocket strip on the inside of the other frame part.
  • the pocket folding machine T shown schematically in FIG. 1 is fed the sheets to be folded in the direction of arrow C.
  • the sheets pass through the folding unit W consisting of folding rollers and folding pockets 1 and leave the pocket folding machine T after passing through a pair of cutting rollers S.
  • the pocket folding machine T shown has four folding pockets 1, namely two upper and two lower ones.
  • each folding pocket 1 is arranged between two spaced frame parts A and B.
  • Each folding pocket 1 has a longitudinal spar 4 on one long side and a longitudinal spar 25 on its other side.
  • the longitudinal spar 4 is laterally adjustable on a bar 2 by means of a screw 3.
  • the longitudinal spar 4 of each folding pocket 1 they are perpendicular in their direction of displacement, i.e. Transversely to the sheet running direction, extending slots 28 are provided through which the shafts of the screws 3 extend.
  • Narrow guide rails 5 are fastened to the bar 2, which in the arrangement shown also extend in the longitudinal direction of the folding pockets 1 and protrude beyond the bars 2 on both sides.
  • each guide rail 5 is guided between the guide rollers 6 mounted on the frame part A, wherein a guide engagement is achieved in that each guide roller 6 has a recess in the center on its peripheral surface, into which a recess extends over the upper one and the lower surface of the bar 2 extending part of the narrow guide rail 5 engages.
  • Further guide rollers 6 are arranged in the longitudinal direction of the fold pocket 1, starting from the guide rollers 6 on the frame part insertion side, at a distance which prevents the fold pockets 1 from tilting.
  • a guide plate 8 (FIG. 2) can also be provided, which, as shown in FIG. 4, has a recess into which the guide rail 5 projects with its projecting upper part, as a result of which a guide engagement between the guide plate 8 and the Guide rail 5 is effected.
  • the rack 13 meshes with a pinion 12, which is seated on an axle mounted on the frame part A, which ends on the outside of the frame part A in a square, onto which a crank 11 with a corresponding square opening can be plugged.
  • the pinion 12 When the crank 11 is rotated in the corresponding direction, the pinion 12 thereby rotated displaces the rack 13 with the bar 2 and the guide rail 5 and with the longitudinal beam 4 and the folding pocket 1, the guide rail 5 being provided between the guide rollers provided in pairs above and below 6 and optionally guided through the recess in the guide tab 8.
  • the guide rail 5 is in each case on a pocket bar 9 fixed on the frame part A, which can be seen from FIGS. 2 and 4, while the longitudinal bar 4 corresponding to the other frame part B corresponds to the longitudinal bar 25 corresponding to a pocket bar fixed on the inside of the frame part B. 26 rests.
  • an axially adjustable locking bolt 14 is seated in the frame part A, which can engage in a bore 15 provided in the guide rail 5 in the extended position of the folding pocket 1.
  • the folding pocket 1 can also be shifted further in its longitudinal direction beyond this engagement position up to a position in which the front edge 17 (FIG. 1) of the guide rail 5 has left the guide given by the roller 7 or the tab 8.
  • a bore 16 is provided in the guide rail 5 for locking by means of the locking bolt 14.
  • the folding pockets 1 can be fixed in the respectively set position with the aid of an eccentric lever 10. While the folding pockets 1 with their longitudinal spars 4 and 24, their strips 2 and guide rails 5 are arranged between or within the frame parts A and B, the actuating arm of the eccentric lever 10 is located outside the frame part A. A rod extends through the frame part A. of the eccentric lever 10. When the eccentric lever 10 is in the appropriate position, an eccentric element located within the frame part A presses against the guide rail 5 such that it is pressed against the pocket bar 9, which causes the folding pocket 1 to be clamped. Since the actuating arms for the eccentric lever 10 for each folding pocket 1 are arranged on one and the same side of the frame part A, the setting of the folding pockets 1 can be carried out simply and quickly. With a corresponding configuration, the eccentric lever can also press the guide rail 5 in a clamping manner against the inside of the one frame part A.
