Definitions

  • the present invention relates to a device for perforating, die-cutting, cutting or creasing at printing machines according to the introduction of independent claim 1.
  • the invention relates also to the use of the inventive device for envelope printing or spot varnishing.
  • a counter-pressure device for effectuating perforations and/or punching at offset sheet printing machines is known from the US-A-5 623 874 of the same applicant.
  • that known device it is particularly provided for to replace the rubber blanket by a hard foil which can be mounted by a fixing means to the rubber blanket cylinder of a printing unit or to the forme roller of a coating unit.
  • the use of a hard foil instead of the rubber blanket resulted in a significant improvement with respect to the then known state of the art, particularly by allowing very precise punching and perforating and an increase in the passing rates in perforating. It has, however, proved that the use of such known device is not recommended in endless printing machines.
  • a coating unit can either be used for coating or for punching, creasing or perforating.
  • the circumference of the coating forme roller is equipped with a punching sheet steel and the circumference of the printing cylinder with a counter-punching sheet steel or vice-versa, in such a way that the coating forme roller is equipped with a counter-punching sheet steel and the printing cylinder with one or several punching sheets steel.
  • the device is on one side limited to the use in a coating unit and on the other side neither the punching sheet steel nor the counter-punching sheet steel are described more in detail.
  • the device for envelope printing or varnishing comprises is defined in the independent claims 8, 9 and 10. Further advantages and embodiments are defined in the dependent claims.
  • Figure 1 shows schematically one of optionally several printing units in a offset sheet printing machine with a plate cylinder 1, an impression cylinder 2 and a rubber blanket cylinder 3 disposed in-between, on which a supporting foil 4 is mounted instead of a rubber blanket.
  • a conventional rubber blanket is mounted on the rubber blanket cylinder 3.
  • both, the rubber blanket cylinder 3 and the impression cylinder 2 are shown with equal diameters.
  • the means according to the present invention can, however, also be used in printing or coating units presenting impression cylinders whose diameters are twice the diameters of the rubber blanket cylinder and the forme cylinder respectively.
  • the perforation rule 5 is mounted on the supporting foil 4 which itself is affixed to the rubber blanket cylinder 3, usually by a two side adhesive tape, whereby the teeth of the perforation rule 5 are directed towards the impression cylinder 2 in order to perforate the paper running in-between these two cylinders.
  • adequate means e.g. die-cutting forms, cutting forms or creasing rules respectively, are mounted.
  • this includes all possible means for perforating, die-cutting, cutting and creasing.
  • in place of one single perforation rule there may be used several ones.
  • the impression cylinder 2 would be sufficient as a backpressure means. However, it is recommendable to protect its surface by a protection foil 22 made of metal or synthetic material.
  • the protection foil 22 can be affixed by means of a two side adhesive tape. This combination results in a better and more precise perforation or punching of the paper and furthermore allows to maintain the normal printing speed of offset sheet printing or endless printing machines, such that printing, and perforating, die-cutting, cutting or creasing can be effectuated at the same speed.
  • Figure 1 one recognises also an inking system 6 with different inking rollers which transfer the printing ink onto the plate cylinder 1, and a damping system 7.
  • the paper sheet 8 arrives from the intermediate drum 9 to a first feed drum 10, from where it continues towards the impression cylinder 2 and further towards the second feed drum 11, from where the paper sheet 8 may be transferred to a further drum, and if provided for, to a further inking system or a coating unit 19.
  • a further inking system or a coating unit correspondingly, but without the coating unit, this is also true for an endless printing machine.
  • the plate cylinder 1, the impression cylinder 2 and the rubber blanket cylinder 3 are represented on a larger scale and in a sectional view.
  • the plate cylinder 1 with the printing plate affixed to it is well known in the state of the art and differs in its constructive details from one type of printing machine to another.
  • the impression cylinder 2 is equipped with a protection foil 22, to protect its surface.
  • the supporting foil 4 onto which a perforation rule 5 is affixed, if perforating is to be effectuated.
  • the perforation rule 5 may be fixed lengthwise or crosswise.
  • a coating unit 19 is to be used for perforating, die-cutting, cutting or creasing, on one of its cylinders, the forme cylinder 17, the supporting foil 4 is mounted onto which the perforation rule or forme 5 is affixed.
  • impression cylinder 18, the protection foil 22 is mounted on the other cylinder.
  • Both cylinders 17 and 18 are provided with similar fixing means 16 for the parts to be mounted onto them, including rails and strips 13, as the afore mentioned cylinders.
  • a metering roller 20 and a coating forme roller 21 which of course are not in contact with the forme cylinder 17 during perforating, punching and creasing. Underneath the coating forme roller 21 a coat reception basin is traced.
  • a conventional rubber blanket is mounted on the rubber blanket cylinder 3 and the perforation rule or form 5 is taken off.
  • the thickness of the layer(s) mounted on the rubber blanket cylinder 3 are standardised in such a way that a defined distance between the rubber blanket cylinder 3 and the impression cylinder 2 co-operating with same is achieved.
  • the supporting foil 4 has to have the same thickness as the rubber blanket, whereby the thickness of the perforation rule or forme or the sheet metal are to be taken in account. The same applies equally for the coating module 19.
  • a thin metal foil having a thickness of 0.3 mm for example is used.
  • an underlying blanket 15 of 1.65 mm thickness is spread under the foil.
  • This underlying blanket 15 may have a variable stiffness, adapted to the intended use, and e.g. be made from one or several press board plates. It may be fastened on one side only or on both sides, or even be affixed to the foil.
  • the inner underlying blanket 15 of the supporting foil 4 is an independent unit, formed, seen from the side of the rubber blanket cylinder 3, of a combination of at least one calibrated cardboard sheet 14A, having a thickness of between 0.30 to 0.40 mm, and thin aluminium sheets 14B of e.g. 0.30 mm thickness.
  • This unit is at least at one of its sides fastened together by rivets 14C.
  • the first aluminium sheet, seen from the side of the cardboard sheet, is provided with an edge 14D hooked into the front side of the cylinder gap of the rubber blanket cylinder 3, to position the underlying blanket 15.
  • the total thickness of the layers on the rubber blanket cylinder 3 can easily be adjusted to the needs of different types of printing machines, thus avoiding that the printer uses a wrong total thickness.
  • the underlying blanket 15 is simply hooked into the front edge of the cylinder gap and the foil 24 fixed with strips onto the fixing means.
  • top foil 24 is affixed to two opposite strips 13, which are glued or riveted to it.
  • the supporting foil 4 is provided with edges 23 on both of its ends, which edges penetrate into corresponding grooves 25 at the strips 13.
  • the foil 24 may be made of a metal sheet, e.g. chromium steel or any other suitable metal or from synthetic material.
  • the foil In order to protect the surface of the foil it may be convenient to mount on its top side a relatively hard cover foil, for example of synthetic material, which can be replaced by a new one if necessary.
  • cover foil for example of synthetic material
  • the total thickness of the supporting foil must correspond to the thickness of the conventional rubber blanket used in a corresponding application.
  • the strips 13 correspond to those used with the rubber blanket, thus making it possible to use the same or a similar fixing means 16 on the rubber blanket cylinder 3.
  • the supporting foil for perforating together, if necessary, with the underlying blanket and/or the cover foil, no modification of the printing or coating unit is necessary, compared to the use of an usual rubber blanket.
  • a further advantage in using the foil 4 is that the paper sheets are not deformed during perforating or punching. Therefore, the entire stack can be piled up in the same manner as before the perforation or punching. Its transportation is thus considerably facilitated, in contrast to the strongly deformed sheets after perforating with a rubber blanket. Therefore, it is also possible to use foil 4 for punching of different patterns, e.g. address areas or the like.
  • Figure 4 discloses a further advantageous use of the supporting foil, the use of it for printing envelopes.
  • Envelopes have one or two flaps as closure means causing uneven parts, causing folds and the like. The same applies to windows in the envelopes. All these elements cause difficulties for the printing of the envelopes.
  • the arrangement of Figure 4 enables a smooth and good quality printing of envelopes.
  • Figure 4 shows the impression cylinder 2 and the rubber blanket cylinder 3, on which the supporting foil 4 comprising top foil 24 is fastened as in the previous embodiments.
  • top foil 24 is a sheet metal foil.
  • a blanket pad 26 is fastened, the pad having a self-adhesive layer for good adherence.
  • the rubber blanket pad 26 has only the size of the field to be printed, is inked like an usual rubber blanket for printing, and is fastened on the supporting foil at the spot corresponding to the field where the envelope is to be printed.
  • the alignment of the pad is assisted by a coordinate paper fixed on the top foil.
  • the use of the inventive set of supporting foil 4 with the foil 24 enables to print only at the field foreseen for it and avoids the use of a rubber blanket covering the whole rubber blanket cylinder and thus also the folds and unevennesses of an envelope. It is evident that the total thickness of the supporting foil 4 with top foil 24 and pad 26 must be the same as the conventionally used rubber blanket. This is effectuated, as described above, by reducing the thickness of the supporting foil set, e.g. of inner underlying blanket 15.
  • the same set up with the supporting foil 4 comprising the top foil 24 and one rubber blanket pad or several pads can be used for varnishing at one spot, resp. several spots.
  • the spot or spots where the varnish has to be applied has to be projected on the rubber blanket sheet, the rubber blanket is then removed and the space on the rubber blanket where the varnish is not to be applied is subsequently cut out and the rubber blanked with the holes replaced.
  • the rubber blanket pad or pads with a self-adhesive layer can be cut in the size of the spot to be varnished and, since the top foil 24 has a coordinate paper on its surface, the pad(s) can be simply applied upon, without having to remove and replace the supporting foil. This procedure simplifies significantly the spotwise varnishing. It is also possible to prepare the supporting foil with the pad or pads and simply fasten it if varnishing is to be accomplished.
  • spot varnishing can be effectuated as well with the printing unit as with the coating unit, in the latter the supporting foil with the varnishing pads being mounted on the forme cylinder. It is further appreciated that envelope printing as well as spot varnishing is effectuated without protective foil 22 on the impression cylinder.
