Definitions

  • the present invention relates to a method for pressing folded printed products according to the preamble of claim 1 and a device for carrying out the method according to claim 6.
  • a method and a device for pressing folded single sheets is known from DE-A-35 17 775.
  • the folded single sheets are rotated before being inserted into a press nip so that the edges run at an angle to the conveying direction and the folded edge adjoins the leading corner. This twisting of the individual sheets and one-by-one feed to the press nip prevents the press rollers from jumping and an exact rolling along the fold edge is achieved.
  • the thickness of the scale formation thus changes abruptly along the entire width of the scale formation, which leads to a restless pressing process, since the thickness of the press gap must change accordingly adjust large changes in thickness of the supplied scale formation. This can lead to inadequate pressing of the printed products in the area of the folded edges and to uneven running of the press rollers.
  • the printed products are fed to the inlet of a press nip with edges running at an angle to the conveying direction.
  • the folded edge of a printed product is therefore not pressed along its entire length at the same time, but runs one end ahead into the inlet and is successively inserted into the press nip.
  • the pressing along the folded edge and, incidentally, also the other edges of the printed products takes place progressively, similar to a folding or pressing by means of a folding leg, which is brushed along the folded edge. This leads to an optimal pressing of the printed products.
  • the air present in the printed product in particular in the area of the folded edge, can easily escape and furthermore the amount of air that must escape from the printed products per unit of time is smaller than the amount of air that must escape at the same time when the printed product runs into the press nip along the entire length of the fold edge.
  • a particularly balanced pressing process and smooth running of the device for pressing the printed products is achieved in that the printed products overlap in regions as seen in the conveying direction.
  • a printed product always runs into the inlet of the press nip before the printed product leading in the direction of conveyance has already completely passed the inlet.
  • the smallest change in the thickness of the supplied formation and thus the smallest change in the thickness of the press nip occurs when the fold edges of two successive printed products overlap, as seen in the conveying direction.
  • the folded edges are offset from one another in a direction perpendicular to the conveying direction, so that the supplied and to be pressed formation always has essentially the same thickness. This applies both to formations in which the printed products are not arranged next to one another in regions adjacent to one another, and to scale formations in which the printed products lie on one another in the manner of a roof, as viewed in the conveying direction.
  • FIG. 1 and 2 show, in a highly simplified manner, a pressing device 12 downstream of a belt conveyor 10 as seen in the conveying direction F.
  • the endless belt 14 of the belt conveyor 10, which is driven in rotation in the conveying direction F, is guided around a stationary, rotatably mounted roller 16 at its end which is effective for conveying.
  • the conveyor-effective strand 14 'defines a conveyor level which is indicated by dashed lines and is designated by 18.
  • the press device 12 has two press rolls 20, 20 'arranged one above the other, the cylindrical surfaces 22, 22' of which delimit a press nip 24.
  • the inlet 26 of the press nip 24 facing the belt conveyor 10 is also defined by the surfaces 22, 22 ′ approaching each other in the conveying direction F.
  • the two press rolls 20, 20 ' are driven in the direction of arrow A and A' in such a way that the peripheral speed corresponds to the conveying speed v of the belt conveyor 10.
  • the lower press roller 20 is rotatably mounted on lateral bearing plates 28, the surface 22 of this press roller 20 affecting the conveying plane 18.
  • the upper press roller 22 ' is mounted on the end plates 28 in the direction of arrow B, approximately perpendicular to the conveying plane 18, and is prestressed against the lower press roller 20.
  • the axis of rotation 30 of the lower press roller 20 runs parallel to the conveying plane 18 and at right angles to the conveying direction F, whereas the axis of rotation 30 of the upper press roller 20 'can be pivoted about an axis running approximately parallel to the conveying direction F while maintaining its longitudinal direction perpendicular to the conveying direction F.
  • a guide roller 32, 32 ' which is also mounted on the end plates 28, is connected downstream of each of the two press rollers 20, 20'.
  • the axes of rotation 34 of these guide rollers 32, 32 ' run parallel to the axes of rotation 30 of the press rollers 20, 20'.
  • the lower guide roller 32 also touches the conveying plane 18 with its cylindrical outer surface 36.
  • the upper guide roller 32 ' is guided in the same manner as the upper press roller 20' in the direction of arrow B and is biased against the lower guide roller 32.
  • the press rolls 20, 20 'and guide rolls 32, 32' have two corresponding circumferential grooves 38, spaced apart from one another in the direction of the axes of rotation 30, 34, into which two grooves, each around a press roll 20, 20 'and the corresponding guide roll 32, 32' endless belts 40 engaged.
  • the depth of the grooves 38 in the radial direction corresponds essentially to the thickness of the belts 40, so that they do not protrude beyond the surfaces 22, 22 'or jacket surfaces 36.
  • the pressing device 12 is followed by a conveyor 42, which is also designed as a belt conveyor and is driven in the direction of conveyance F at the speed v.
  • folded printed products such as magazines, newspapers and the like are designated, which are arranged in a scale formation S.
  • Each printed product 44 as seen in the direction of conveyance F, lies on the preceding printed product 44.
  • the fold edges of the printed products 44 are denoted by 46, the side edges by 48 and 50, and the open edge, the so-called flower, opposite the fold edge 46, by 52.
  • the printed products 44 are rotated with respect to the conveying direction F by an axis perpendicular to the conveying plane 18, so that the edges 46 to 52 run obliquely to the conveying direction F.
  • the folded edges 46 form an angle ⁇ of approximately 45 ° with the conveying direction F. Of course, this angle can be larger or smaller.
  • the fold edges 46 of two adjacent printed products 44 overlap one another, viewed in the conveying direction F, in an area designated by C, but are spaced apart from one another in a direction perpendicular to the conveying direction F and parallel to the conveying plane 18.
  • FIG. 3 shows, in a highly simplified view, a further embodiment of the present invention.
  • the belt 14 of the belt conveyor 10 runs through the press nip 24 delimited by the two press rolls 20, 20 ', of which only the upper one is visible in FIG. 3 (see FIG. 1).
  • the press rolls 20, 20 ' are driven in a known manner to rotate about the axes of rotation 30.
  • the printed products 44 resting on the belt 14 are arranged obliquely with respect to the conveying direction F, overlap one another in regions in the conveying direction F, but do not lie one on top of the other, viewed in the direction perpendicular to the conveying direction F, in each case in regions next to one another.
  • the folded edges 46 of two adjacent printed products 44 overlap, seen in the conveying direction F, in the area C.
  • the printed products 44, lying on the belt 14, are directed towards the press rollers 20, 20 ', through them and away from them.
  • the press roller 20 Due to the inclined position of the printed products 44 with respect to the conveying direction F, they are fed to the inlet 26 of the press nip 24 with a leading corner delimited by the folded edge 46 and side edge 48.
  • the press roller 20 now rolls successively along the fold edge 46. It develops an effect similar to that of a folding leg running along the folding edge 46, which leads to particularly good pressing.
  • the air contained in the area of the folded edge 46 inside the supplied printed products 44 is gradually pushed out of the printed products 44. The escape of air is now made available at least that time which elapses until the entire folded edge 46 has been introduced into the press nip 24 through the inlet 26.
  • the thickness, perpendicular to the conveying plane 18, of the supplied formation is essentially constant.
  • the fold edges 46 are laterally offset from one another and overlap one another in the conveying direction F, so that the press rollers 20, 20 ′ onto the fold edge 46 Printed product 44 run up before they run from the folded edge 46 of the printed product 44 leading in the direction of conveyance F. This leads to a particularly smooth running of the pressing device 12.
  • the belts 40 guide the printed products 44 in a region following the press nip 24 and thereby prevent the printed products 44 from being carried along along the surfaces 22, 22 'and from bending out in a direction perpendicular to the conveying plane 18.
  • the belts 40 and guide rollers 32, 32 'for pressing the printed products 44 is not absolutely necessary.
  • the printed products can be introduced into the press nip in a scale formation, in which, seen in the conveying direction, each printed product is covered by the preceding printed product.
  • the surface of the lower press roll rolls on the leading fold edge.
  • the one press roller rolls successively along the fold edge, as a result of which the air stored in the region of the fold edge in the printed product can also escape again without problems.
  • the pressing device and the conveyors can also be designed differently than is specified in the exemplary embodiments.
