Definitions

  • Document is known EP-A-1 362 819 , a folding machine for a rotary press which comprises a blade or cutting cylinder provided with a blade adapted to cut a strip of material to be printed as well as several counter pressure elements cooperating with the blade and arranged so as to form interstices axial between them.
  • Tape straps extend into the axial interstices that serve to guide the printed web or die cut signature.
  • the timing belts comprise counterpressure elements which are placed in the aforementioned axial interstices.
  • the blade also applies to the counterpressure elements of the belts during cutting.
  • This folder has the disadvantage that the belts are quickly damaged by the blade, and must be regularly changed.
  • the invention aims to overcome this disadvantage and to propose a folder which has longer maintenance intervals.
  • the invention relates to a folder as indicated above, characterized in that the blade extends over the axial gap, and in that the conveying element extends into the axial gap at a distance from the blade when the blade cooperates with the counter-pressure elements.
  • Figure 1 a folder according to the invention, designated by the general reference 2.
  • This folder 2 is adapted to cut and fold a strip of material to be printed, such as a paper strip 4.
  • the paper strip 4 may have one or more layers.
  • the band 4 is driven with a band speed V 1 .
  • the folder 2 is equipped with two pairs of traction rollers 6 and 8 of the strip 4.
  • the folder 2 comprises a blade or fold cylinder 10, a counter-pressure cylinder 12, a transfer cylinder 14 and two cylinders transfer device 16.
  • the folder 2 is adapted to cut the web 4 into signatures 18 or sheets 18 and to transport the signatures / sheets with a signature speed V 2 which is preferably greater than the web speed V 1 .
  • the blade cylinder or fold cylinder 10 and the counter-pressure cylinder 12 define a cutting location 19 between them, which corresponds to the closest place between these two cylinders 10, 12.
  • the blade cylinder 10 has a peripheral speed which is equal to the signature speed V 2 .
  • the speed of rotation of the counter-pressure cylinder 12 is adapted to the speed of the blade cylinder 10 so that a counter-pressure element 26 is always present when a blade 20 bears on the belt 4 in order to cut it.
  • the blade cylinder 10 has three blades 20 uniformly distributed over the circumference of the cylinder 10.
  • the blades 20 are fixed on the blade cylinder 10 in a retracted position in which the cutting edge of the blade 20 is recessed behind the circumference of the cylinder 10
  • Each blade 20 preferably extends uninterrupted over the entire axial width of the cutting band 4 or the blade cylinder 10.
  • the blade cylinder 10 is further provided with two protective blocks 22 of elastic material such as rubber which extend on either side of the blade 20 associated.
  • Clips 24 which are adapted to hold cut signatures 18 are also arranged on the blade cylinder 10.
  • the counter-pressure cylinder 12 comprises one or more counterpressure assemblies 25, each of which is provided with a plurality of counterpressure elements 26, which will be explained in detail below.
  • the folder 2 is provided with a plurality of first conveying elements, in the form of a first bank of first belts 28, which extend around the counterpressure cylinder 12, which are applied to a segment of the surface of the blade cylinder 10 and on a segment of the surface of the counter-pressure cylinder 12. These belts 28 are adapted to convey the web 4 and / or a cut-off signature 18 downstream of the cutting location 19.
  • Each first belt 28 has a round or rectangular cross section and a smooth or slightly rough transport surface. This smooth surface reduces smearing of the tape.
  • Each first belt 28 has a speed that is equal to or greater than the tape transport speed V 1 .
  • the first belts 28 are driven at a speed which is greater than the belt speed V 1 and equal to or less than the signature speed V 2 and in particular strictly less than the signature speed V 2 .
  • the traction of the belts 28 on the band 4 and on the signatures 18 is limited and cleans the paper.
  • the folder 2 further comprises a plurality of second conveying elements, in this case belts 30, which form a second belt bench.
  • belts 30 of the second belt bench are nested between the belts of the first belt bench 28 so that a signature head 18 can pass from the first belt bench 28 to the second belt bench 28. 30.
  • the belt speed of the second belt bench 30 being identical to the peripheral speed of the blade cylinder 10.
  • the protection blocks 22 are adapted to contribute to a protection on the one hand of the first belts 28 and secondly of the second belts 30 against wear by the blades 20.
  • these protective blocks 22 hold the paper strip 4 against the back pressure elements 26 at the time of cutting.
  • FIG. 5 is a perspective view of a detail of the counter-pressure cylinder 12. As can be seen, the counter-pressure elements 26 are arranged axially one behind the other in an aligned manner, and forming interstices 32 between them interstices 32 in which the first belts 28 engage when cutting the paper web 4.
  • Each set of back pressure 25 extends axially along the counter-pressure cylinder 12.
  • Each counterpressure element 26 has an axially extending cutting groove 34 into which the blade 20 engages during cutting.
  • a bearing surface 36 On each side of the groove 34 is disposed a bearing surface 36, which extends parallel to a tangent of the surface of the blade cylinder 10, and which receives the paper web 4 under the action of the protective blocks 22. at the moment of cutting.
  • the bearing surface 36 is shifted outwardly with respect to the surface of the blade cylinder 10.
  • Guide grooves 40 are provided in the counter-pressure cylinder 12. These grooves 40 are aligned with the interstices 32 and extend circumferentially around the cylinder 12. In these guide grooves 40 engage the belts 28.
  • the axial dimension of the gap 32 is chosen so that the strip 4 is cut by the blade 20 in the entire zone corresponding to the gap 32. Thus the strip 4 is cut across its width in a single surgery.
  • FIG 8 is shown a second embodiment of the folder according to the invention.
  • This folder 2 differs from that previously described by the following. Similar elements bear the same references.
  • the first belts 28 are wound on a segment of the blade cylinder 10 upstream of the cutting location 19, and are adapted to hold the web 4 in an area extending from the cutting location upstream, and this at the moment of cutting. Thus, the end of the band 4 that is created by the cut is maintained.
  • the first belts 28 completely surround the counter-pressure cylinder 12 and are deflected by three deflection rollers 50. Consequently, the first belts 28 come into contact with the counter-pressure cylinder 12 only in the defined zone. by the counter-pressure elements 26, or are out of contact over the entire circumference of the counter-pressure cylinder 12.
  • This embodiment facilitates the driving of the first belts 28 at a speed V 3 different from the belt speed V 1 or the signature speed V 2 .
  • the second belts 30 are not shown in this figure.
  • Figure 9 is shown a third embodiment of the folder according to the invention.
  • This folder 2 differs from the folder previously described by the following.
  • the first belts 28 apply, downstream of the cutting location 19, against the blade cylinder 10 on a segment which corresponds to approximately 170 °, that is to say to a transfer location of the signature 18 to the transfer cylinder 14.
  • the belts 28 thus extend around three return rollers 50.
  • the second belts 30 can be omitted, while ensuring a good guiding of the cut signature 18 to the vicinity of the transfer cylinder 14.
  • the counter-pressure cylinder 12 carries a plurality of counter-pressure assemblies 25 or counter-pressure elements 26 distributed around its circumference.
  • the blade cylinder 10 is adapted to be rotated so that its peripheral speed is greater than the speed V 1 of travel of the web 4 of material to be printed and is equal to the speed V 2 .
  • the blade cylinder 10 is adapted to be rotated so that its speed is equal to the running speed V 1 of the web 4 of material to be printed.
  • the speed V 2 is equal to the speed V 1 .
  • the back pressure assembly 25 and thus the counterpressure elements 26 are made in one piece, the gap 32 between two counterpressure elements being formed by a groove or guide groove of 28.
  • This variant facilitates assembly and manufacture of the folder.
  • the cutting groove 34 may be omitted.
  • the belts 28 can be replaced by another conveying element, for example a chain.
