  • Booklet covers are often provided with flaps that are folded in only make up part of the block width or extend all the way to the edge.
  • the invention has for its object, in particular in a commercially available Three-knife trimmer with the front cut after hanging brochures projecting or flush flaps so that despite usual unavoidable production fluctuations the flaps on the front of the book are not cut or damaged.
  • the Device at least one suction element for fetching and retracting the Flap edge from the cutting plane in the area of the brochure to be trimmed having.
  • the device according to the invention Envelope briefly moved so far out of the cutting area that a the block can be cut safely.
  • the envelope can be trimmed after sliding back to the starting position either stand back slightly, be flush or protrude.
  • a standard three-knife trimmer with such a suction element become. This is based on the idea of a standard machine as the carrier of the To use equipment that, if not used for flap brochures, can be used elsewhere. The additional pass through the Perfect binding system is avoided, rejects by cutting flap edges is avoided and is therefore more economical to manufacture Generic brochures achieved. English brochures can also be used in this way manufacture particularly economically.
  • the suction element can be integrated in a commercially available three-knife trimmer In addition to the front cut, the head and foot are also cut at the same time. This can be done very easily on a three-knife trimmer, the head / foot trimming and front cut in two separate stations, as a so-called flow three-cutter, performs. It does not matter whether the front cut is first or is executed afterwards. The mechanical effort for saving the second Passage in the production of brochures with folded, protruding Flap is then limited to the flap retractor in the form of suction element according to the invention.
  • the suction element Hold-down is assigned. After the envelope bulges and retracts This hold-down prevents the flap edge from the cutting plane accidental sliding back of the flap edge. The hold-down presses the flap firmly attached to the block when trimming.
  • suction elements preferably linearly along one Straight lines are provided, which is arranged parallel to the block back.
  • This Setting would not be a strip-shaped configuration of the suction element It is so easy to carry out, because then there is false air on the pages of smaller brochures could enter the vacuum cleaner and thereby disadvantageously reduce the suction power.
  • suction elements to dent and Retracting the flap are arranged so both flaps, both the upper as well as the lower flap of the envelope, are pulled back so that after sliding the flaps back over the front of the block can stand out.
  • the distance by which the flap is dented and withdrawn can be advantageous set independently of the vacuum of the suction element when a drive is provided, preferably a piston-cylinder unit, around the suction elements a suction to move to a stop position and back, this Direction of movement preferably inclined to a normal to the flap is.
  • the desired projection of the flap over the front block edge can be conveniently set when adjusting elements for adjusting the intake and / or Holding position of the suction element are provided.
  • the suction element has a suction cup in the Direction of movement is movably mounted. This allows the suction element follow the natural movement of the flap without being forced onto the surface exercise.
  • the suction cup is a support structure for has the flap.
  • the forces exerted on the valve by the vacuum can be drained over a large area within the suction cup, without marks to leave on the flap.
  • suction cup is in at least one direction transverse to the direction of movement is slidably mounted, even slight lateral movements be balanced.
  • the support structure has a concave envelope surface nestles Suction cup on the flap without leaving any marks on the flap.
  • the careful handling of the flap also serves the measure that the Suction and / or the holding position of each suction element individually and is adjustable independently of the others.
  • the flap can switch in automatically by switching off the vacuum slide back to their original position without additional mechanical stripping elements to have to provide.
  • the forces exerted on the flap can be adjusted particularly sensitively, characterized in that a throttle point in the channel between the suction element and vacuum is provided, which is preferably adjustable and / or closable.
  • a throttle point in the channel between the suction element and vacuum is provided, which is preferably adjustable and / or closable.
  • it is an object of the invention to provide a method for trimming Brochures along a cutting plane at the front of the brochure with projecting or flush flaps of an envelope in which a block is hung is to indicate that it is more productive than known production methods.
  • the generation of the bulge in the Flap is done using vacuum.
  • the use of a vacuum for Generation of the bump has the advantage that the flap is largely protected and there is no risk of injury from mechanical manipulation devices can.
  • the front can be trimmed can also be done in double format. For this purpose it is provided that the trimming done in double benefit.
  • the brochures are then fed to a separating saw and forwarded to a three-knife trimmer, where the head and foot cuts were made become.
  • the process is advantageously integrated into a commercially available three-knife trimmer, the In addition to the front cut, the head and foot are also cut at the same time.
  • FIG. 1 schematically shows a section through the flap retraction device 1 shown how it is used as part of a standard three-knife trimmer.
  • the Figure 1 shown situation corresponds to the rest position. In this rest position it is closed trimming brochure 2 in its trimming position on the cutting table 4 has been brought.
  • the brochure 2 consists of a book block 3, which is in an envelope 5 is attached.
  • the envelope 5 has an upper flap 6 and a flap lower flap 7, which encompasses the book block 3.
  • Both the Flaps 6 and 7 as well as the book block 3 are over the dash-dotted lines section plane 8 shown above.
  • On both sides of the flaps 6 and 7 are a knife 9 and a counter holder 10 is positioned.
  • Above the upper flap 6 is a vertical one movable hold-down 11 is provided.
  • Both in the hold-down 11 and in Cutting table 4 are in the rear area of brochure 2 parallel to the spine 12 two recesses 13 and 14 for an upper and a lower suction element 15 and 16 are provided.
  • the recesses 13, 14 laterally towards the envelope limited by rounded edges 17.
  • the suction elements 15, 16 are relative to Cutting table 4, as well as movable to hold-down device 11 in the direction of arrows 18.
  • the movement is carried out by piston-cylinder units, for the sake of clarity are not shown in this schematic representation
  • the suction elements 15, 16 can for example be strip-shaped suction elements be formed, the longer extension of which is perpendicular to the plane of the drawing.
  • the counter-holder 10 On its front edge, which lies opposite the cutting plane 8 or the knife 9, the counter-holder 10 has a projecting ledge 19, the height of which approximately Thickness of the lower flap 7 corresponds.
  • the recesses 13, 14 with the suction elements 15, 16 in a retrofittable receptacle 20 or 21 is provided which on the hold-down device 11 or cutting table 4 was retrofitted.
  • FIG 2 shows the situation of the parts shown in Figure 1 during the cut the leading edge 22.
  • Piston cylinder units moved the suction elements 15, 16 in the direction of the arrow 17, 18 until they touch the flaps of the brochure. Then the suction elements pressurized so that they suck in the flaps. Once a sufficient one Holding force is developed, the suction elements 15, 16 in the direction of arrows 23, 24 moved away from the book block. This movement takes place at an angle ⁇ ⁇ Normals on the book block. This forms an upper and a lower dent 25 and 26 in the envelope. This will remove the front edges of the flaps from the Section plane 8 pulled back to the spine 12.
  • the hold-down device 11 moves back into its starting position.
