Definitions

  • the invention relates to a method by means of which label strips or comparable flat material strips are separated from a flat material web, that is to say they can be cut out.
  • the invention also relates to a device with which this method can be carried out.
  • Such a separation of flat material strips from a flat material web takes place, for example, in the production of individual labels.
  • the individual labels may have a rectangular or other, any desired outline shape.
  • Such individual labels are used in large quantities, for example in the food industry, for example as beer bottle labels or for cheese boxes or other food packaging.
  • Label strips regularly have several identical labels. These labels are known to be printed on sheetfed presses or web presses on a corresponding flat web. Subsequently, large sheets are stacked with printed labels. Of these stacked large bows are usually intestinally manually several layers of sheets, approximately at a height of about 100 millimeters, removed and shaken in a jogger to a ridge-accurate small pile. From such a small stack then individual strip stacks are separated on a so-called guillotine cutter. From these stacks of strips then the individual labels, for example, also separated by means of a guillotine cutter. If the labels have a shape deviating from the rectangle, correspondingly shaped punching dies are used for severing the strip stacks into the individual individual label blocks.
  • the so-called squeeze-cutting method instead of the scissors cutting method carried out by means of cross-cutters, as is known for the production of self-adhesive labels or for punching out any shapes from paper webs.
  • the material to be cut is separated with a sharp knife edge against a generally smooth, hardened and ground surface.
  • the gap between the knife edge and the surface is set to practically zero, so that the knife during the cutting process, although the material separates like an ax, but the knife edgesser on the hardened counter surface is not damaged.
  • This method can be applied rotationally by means of a punching plate, for example, mounted on a magnetic cylinder or a milled, engraved cylinder.
  • the advantage of this cutting method lies in particular, that can be arranged at the intervals of the cutting cylinder any number of cutting edges with any distances and cutouts.
  • the investment for a stamped sheet is relatively low, and required for a job change replacement of the punching sheet against another stamped sheet takes only a few minutes.
  • the disadvantage, however, is that the production of narrow narrow strips in the running direction is extremely critical, since for stability reasons, the cylinder diameter of cutting and counter-cylinder should not be less than about 150 millimeters to absorb the forces occurring during the cutting process and ensure a clean cutting result can. But then it becomes very difficult to transport in the direction of short strips, which are separated from the flat material web, out of the region of the cutting counter-cylinder to subsequently stack the strips.
  • the present invention seeks to be able to produce flat material strips such as in particular label strips with any, in particular the smallest possible length economically inexpensive from a flat material web.
  • the invention includes that the printed flat material web is severed to at least a small area in the transverse direction and then that longitudinally not completely severed flat material web is severed in the longitudinal direction so that the transversely unintersected each small area is now separated from the respective strip of flat material ,
  • the individual label strips or other strips of flat material can therefore be severed once, except for a few millimeters, up to the lateral web edges of the flat material web. Subsequently, the individual strips by a separation process in the direction in which the example side bars are separated generated. Thus, cutting across the direction of travel does not yet produce the individual strips; rather, the individual stripes still hang together like a kind of ladder. Only in a subsequent longitudinal cutting process, as it were Holmen this ladder are separated, so that only the sprouts in the form of label strips are available.
  • the label strips which are connected in the manner of a ladder can easily be pulled out of the region of the cross cutter in the direction of travel because the "ladder" produced in the cross cutter is still connected integrally to the uncut flat material web via the ladder rails.
  • the spars or the small areas that are not severed in the transverse direction not necessarily be provided at the edge of the flat material web. It would also be possible to additionally or alternatively provide this small area or several such areas in the central region of the flat material web.
  • their arrangement at the two lateral edges is of particular advantage. So these edges are generated anyway for the offset printing for the needed color control points and register marks. Therefore, by the invention no additional paper consumption.
  • the cross-sectional cuts are made in particular by a punching process.
  • the known in the art per se punched sheet cross cutter can be used.
  • the parting cuts may include transverse linear cuts or cuts that delimit a cutout circumferentially.
  • cutouts are to be punched in particular, these cutouts can be brought out of the flat web by suction and subsequent blowing away in an economically simple manner.
  • a flat material web 10 has been printed by rotary printing in the offset printing process with images of labels 12 and is unwound in the running direction 14 through a cross cutter 16 (FIG. 4).
  • the drawing shows only some of these labels.
  • the punching lines 18, 20 produced in the cross cutter 16 can be seen in FIG.
  • the labels 12 are present in the running direction 14 one behind the other and in addition to several printed in the transverse direction 22 on the flat web 10.
  • Several transverse labels 22 adjacent labels 12 are each present only in a label strip 24, which, as described below, yet produced.
  • the cross cutter 16 of these individual label strips 24 they are made in the direction of 14 separate boundary lines as so-called transverse punched lines 18.
  • the transverse punching lines 18 do not extend in the transverse direction 22 over the entire flat material web 10, but save on the left and right longitudinal edge of the flat material web extending in the transverse direction 22 width 26, 28, which are the same size in the present case. In the region of this width 26, 28, the flat material web 10 is not severed in the transverse direction 22.
  • a punching frame 20 is also produced from two such transverse punched lines 18 and two longitudinal punched lines 29 joining them longitudinally in the longitudinal direction.
  • the punched lines 18 and the punching frame 20 are produced by means of a punching plate 30 in the flat material web 10.
  • This stamped sheet 30 has corresponding line-shaped punched edges 32 and a frame-shaped punched edge 34.
  • the punching lines 18 and the frame-shaped punching edge 34 of the punching frame 20 in the flat material web 10 are produced by the linear punching edges 32.
  • the length and the shape and the distances of the punching edges 32 and the punching edge 34 on the punching plate 30 thus correspond to the punching lines 18 and the punching frame 20 on the flat material web 10.
  • the punching edges 32 have on the punching plate 30 a mutual distance 36, the distance from adjacent punching lines 18 in the direction 14 on the flat web 10 corresponds.
  • the cross cutter 16 has a cutting cylinder 40, on which the punching plate 30 is attached.
  • the length 42 of the punching sheet extends circumferentially around the cutting cylinder 40 except for a short portion. Between the two transverse edges 44, 46 of the punching plate 30 is on the cutting cylinder 40, a clearance length 47 available in which no punching plate 30 is present.
  • punched edges 32.1, 32.2, 32.3, 32.4, 32.5 and 32.6 are present in the present example case.
  • a strip 24.b Between the punched edges 32.1 and 32.2 is a strip 24.b, between the punching edges 32.2 and 32.3 a strip 24.c, between the punching edges 32.3 and 32.4 a strip 24.d and between the punching edges 32.4 and 32.5 a strip 24.e generated.
  • the last strip 24.a is composed of a strip 24.a1 and a strip 24.a2.
  • the strip 24.a1 is present between the punching edge 32.1 and the lower transverse edge 44 and the remaining partial strip 24.a2 between the upper transverse edge 46 and the punching edge 32.6.
  • the punched edges 32.5 and 32.6 are part of the frame-shaped punched edge 34.
  • the partial strip 24.a1 has a residual length 50 which is smaller than the distance 36 between adjacent strips. The same applies to the remaining length 52 of the strip 24.a2.
  • the strip 24.a is thus composed of the two strips 24.al, 24.a2 and from the free space length 47. This free space length 47 or the resulting space formed between the transverse edges 44, 46 is used to attach the punching plate 30 on the cutting cylinder 40th needed.
  • the length of the longitudinal punching line 29 of the frame-shaped punching line 20 corresponds to the cutout length 57 of the frame-shaped punching edge 34.
  • the cutting cylinder 40 cooperates with a counter-pressure cylinder 58 by passing the flat material web in the running direction 14 with corresponding rotation of the two cylinders 40, 58 between them.
  • the flat material web still hangs in one piece in the region of the cross cutter 16, it is only partially separated in the manner of a conductor by the punched lines 18 or the frame-shaped punching line 20.
  • the cut-out 60 produced by the punching frame 20 is kept sucked on the cutting cylinder 40 after its generation by corresponding negative pressure generated in the interior of the cutting cylinder 40, and after about a quarter turn of the cutting cylinder 40 blown away therefrom by a corresponding air blast and fed to a waste container.
  • the flat material web is pulled out of the cross cutter 16 by means of a suction belt conveyor 62 arranged below the flat material web 10 and a loading belt conveyor 64 lying on top of the flat material web 10 through the cross cutter 16 and fed to a longitudinal cutter 66.
  • the longitudinal cutter 66 has left and right longitudinal roller cutters 68, 70 which act on the flat material web from above and cooperate with the left and right counter rollers 72, 74 arranged below the flat material web 10 in the silhouette.
  • a left and right side strips 76, 78 is separated from the Machmaterialbahn 10.
  • the two side strips 76, 78 have the width 26 and 28 respectively.
  • the individual label strips 24 are produced by the cutting off of these two side strips 76, 78 and deposited on a conveyor belt 82 with the scale scale 80 stacked on top of each other.
  • the scaly superimposed label strips 24 are then, which is not shown in the drawing, placed in the usual manner to a strip stack exactly on top of each other, so that by means of cutting or separating or punching devices from the individual strip stacks block-like superimposed labels, in the present case in 4 blocks, can be cut out.
