Definitions

  • the invention relates to a method for performing an edge cut by means of a cutting apparatus Handling of printed matter in which the Printed products with along a first conveyor loop below Compliance with a mutual distance circumferential, in Area of an edge of the printed matter attacking and grippers carrying them along the first conveyor loop are supplied, and one for executing such Device that can be used in the method.
  • CH-PS-668 216 describes the printed matter to perform the edge cut from the along the first conveyor loop revolving grippers of a feed conveyor released and so from above in an endlessly driven Pockets fixed, open pockets thrown up. In the pockets they are then used to make the edge cut moved perpendicular to the drive direction, after which the thus aligned printed products with a second endlessly driven traction element, one of a strand runs parallel to a section of the first traction element, specified, mutually assigned knives trimmed will. After that, the printed products from while maintaining a mutual distance Gripping a conveyor and thus out of pockets removed and transported away.

  • the Circulation of the knives assigned to one another in pairs on the Circulation of the bags required.
  • the vote between the circulation of the knives and that of the pockets not only in terms of the speed of circulation but also with respect to the circulation phase, because it already is inadequate phase adjustment the further workflow obstacle to the displacement of printed matter in the pockets if one of the two pairs assigned knife too early, i.e. before creating the appropriate one Counter knife, in a cutting engagement with the Printed product arrives.
  • the object of the invention is to provide one the reliable execution of an edge cut permitting procedure for the handling of printed matter and one for carrying out such methods deployable device.
  • this task does solved that the printed products from the grippers in one with the first conveyor loop along a common path of movement co-rotating second conveyor loop with at a distance the gripper arranged clamps inserted be, the clamps in the course of the common Path of movement with the free edge areas to be trimmed the one in the grippers of the first conveyor loop Printed products are brought into stabilizing engagement and in this state the edge cut from that to the common Movement path of fixed cutting device at the over the clamps to the cutting device protruding free edge areas of the printed matter is executed, and the trimmed printed matter connect the common path of movement lengthways in the grippers leave the first conveyor loop.
  • Applicable device for handling printed matter to perform an edge cut is essentially distinguished by a number along a common path of movement coinciding with the first conveyor loop second conveyor loop rotating, arranged at a distance from the grippers Clamps in which the printed products in the Course of the common path of movement can be introduced by the grippers and with which edge areas that cannot be trimmed of the printed products lying in the grippers can be stabilized are off, and in that the cutting apparatus for Execute the edge cut on the over the clamps towards the cutting device projecting free edge areas of the Printed matter fixed on the common path of movement is arranged and the printed matter in the terminal the common path of movement in the grippers along the first Conveyor loops can be removed.
  • the printed products are in the Only roughly aligned grippers. Furthermore the grippers of an ordinary gripper conveyor and therefore also the printed products carried with it usually subjected to significant vibrations or even deflections. To ensure an accurate edge cut is it is therefore expedient if the grippers in the course of the common Path of movement from the printed products contained therein solved and only after making the edge cut again to be applied to the printed matter.
  • the grippers of the device according to the invention are closed this purpose in the course of the common path of movement of one Closed position adjustable in a release position.

Since the Clamps only in the course of the comparatively short common path of movement are required second conveyor loop much shorter than the first conveyor loop be carried out. That allows a vibration and deflection-free guidance of the clamps along the second Conveyor loop with reasonable design effort. The use of the clamps therefore opens up an inexpensive one Possibility of performing an exact edge cut.
  • the clamps and the are expedient second conveyor loop formed so that the printed products while moving on a jaw of the Place the clamps and only after moving them vertically to the direction of conveyance by applying another jaw the clamp can be stabilized.
