Definitions

  • the present invention relates to improvements to devices for printing and decorating continuous web materials, in particular but not exclusively webs of tissue paper for producing rolls of toilet paper, rolls of kitchen towel, paper napkins, facial tissues or the like.
  • printing is frequently used to decorate the web material, possibly in combination with embossing.
  • printing is typically a continuous printing, for example constituted by one or more colored and variously decorated strips, which extend for the entire length of the web material wound in each single roll.
  • the rolls of tissue paper are decorated with repetitive patterns which are repeated with a specific pitch along the entire length of the roll.
  • the printed decoration is implemented with several colors, using a printing unit with several plate rollers, typically one for each color.
  • the colors are combined to form a decorative pattern repeated with a certain pitch along the entire length of the roll, so that in general each roll or pack of web material has the same repeated pattern or a very limited number of repeated patterns.
  • the limit to the number of printed patterns differing from one another is due to the extension of the printing plate.
  • the printing plate will have an extension equal to a multiple of the longitudinal dimension of the sheets into which the web material is divided by transverse perforation lines, when the article being produced is, for example, a roll of kitchen towel or toilet paper.
  • the maximum diametrical dimension of the plate roller the number of different designs that can be repeated on the article never exceeds a few units.
  • An object of an embodiment of the invention is to provide a printing unit to decorate a continuous web material, intended to be divided into single sheets or portions, to form packs of napkins or other folded articles or, more typically, packs of material in roll form, with which decorative effects better than those currently in use can be obtained.
  • the invention provides for a printing unit comprising a plurality of plate rollers disposed in series along a path of the web material, so that said web material is decorated with a print obtained by the combination of designs printed by said plate rollers, wherein at least some of said plate rollers have printing plates with printing extensions of different lengths from one another, equal to multiples of the longitudinal dimension of the sheets into which the web material is divided and each of the plates has a plurality of motifs of a length equal to said longitudinal dimension. Moreover, on each printing plate there is provided at least one series of designs different from one another and the designs of the plates of said at least two rollers differ from one another at least in part.
  • a plurality of series of sheets different from one another can be obtained, in which, for example, a single series covers 20% or more of the entire product. It is also easy to obtain more numerous sequences, up to several hundreds of different designs. This is particularly useful and interesting in the case of packs in roll form, where the single sheets can constitute a series of even very numerous designs different from one another.
  • all the plates of the printing rollers have print extensions of different lengths from one another and at least some and preferably all of the rollers have different diameters, and of a value such that the circumferential extension of each plate roller is equal to a multiple of the longitudinal dimension of the single sheet.
  • the printing unit With initial reference to Figure 1, the printing unit, indicated as a whole with 1, has a common central counter-roller 3, around which the path of a continuous web material N extends.
  • Four printing units 5A, 5B, 5C and 5D are arranged along the periphery of the counter-roller 3.
  • each unit comprises schematically an inker, an anilox roller, and a plate roller. These three elements are indicated with the numbers 7, 9 and 11 followed by the letter A, B, C, D for each of the four units 5A, 5B, 5C, 5D.
  • the plate rollers 11A and 11D have the same diameter, while the plate rollers 11B and 11C have diameters that differ from each other and from the rollers 11A, 11D.
  • the plate rollers could be designed with diameters all of different dimensions from one another.
  • the number of the printing units can also differ from the number indicated; for example two or three printing units could be provided, or also a number in excess of four.
  • the plate rollers 11A, 11C can be designed with a diameter of 401.07 mm so as to have a circumferential extension equal to 1.260 mm, i.e. six times the extension of the single sheet of web material.
  • the plate roller 11 B can have a diameter of 267.38 mm with a circumferential extension of 840 mm, equal to four times the longitudinal extension of the sheet into which the web material is divided.
  • the plate roller 11C can have a diameter of 334.22 mm with a circumferential extension of 1,050 mm equal to five times the length of the sheet into which the web material is divided.
  • the circumferential extension of each plate roller 11A, 11B, 11C, 11D corresponds to the extension in length of the respective plate. Naturally, the dimensions indicated are provide purely by way of non-limiting examples.
  • Figure 2 shows a planar development of the plates of the four rollers 11A-11D. More specifically, A indicates the extension of the plate of the roller 11A divided into six portions, each of which has along the circumferential extension a length L equal to the length of the sheet of web material. The six designs are in fact divided into two series of three designs each, where the two series are identical. A1, A2 and A3 indicate the three designs of each series that differ from one another, which are repeated twice along the extension of the plate.
  • the letter B in Figure 2 indicates the extension in the plane of the plate mounted on the plate roller 11B.
  • This plate has four designs B1, B2, B3, B4 different from one another and different from the designs A1-A3 reproduced on the plate A.
  • the letter C indicates the extension in the plane of the plate mounted on the plate roller 11C.
  • This plate has on the extension thereof five designs C1, C2, C3, C4, C5, each of a length in machine direction (i.e. circumferential) again equal to L, all different from one another and also different from the designs A1-A3, B1-B4.
  • D indicates the extension in the plane of the plate mounted on the plate roller 11 D.
  • This plate has a length equal to that of the plate A mounted on the roller 11A.
  • six designs, all different from one another, are produced thereon and are indicated with D1, D2, D3, D4, D5, D6. As well as being different from one another, these designs are also different from the designs C1-C5, B1-B4, A1-A3.
  • the color of the ink with which the four printing units 5A-5D are supplied differs from unit to unit. It is thus possible, with the four plates described above, to obtain designs formed by various combinations of the designs A1-A3, B1-B4, C1-C5 and D1-D6 in four distinct colors. However, it would also be possible for two or more printing units 5A-5D to use ink of the same color.
  • Figures 3A-3G indicate the perforation lines P formed on the web material N by a perforator unit of a type known per se and not shown. It must be understood that when the printing unit of the present invention is produced to be positioned in a converting line for producing rolls of kitchen towel, toilet paper or the like, the various rollers of which it is composed will have a length equal to the length of the logs formed, which are then cut transversely to obtain single rolls of the desired length, equal to La in Figure 3A. In this case it must be understood that each plate A-D will have, for example, repeated axially for an adequate number of times until reaching the required axial length, the designs shown in Figure 2.
  • each plate roller the respective plates can be mounted staggered, for example by one step, with respect to one another. Functional and aesthetic advantages are thus obtained. From the point of view of function, repetitive concentration of contact areas in an axial direction is avoided, consequently decreasing or eliminating vibrations. Aesthetically, rolls are obtained which, although formed by single sheets different from one another, are all different from the adjacent rolls at the time of transverse cutting and subsequent packaging. In this way it will be possible to obtain packs of products (for example, in the case of rolls) different from one another.
  • the plate rollers can be covered with plates that differ from one another.
  • the variety of subjects on each sheet and/or on each roll is multiplied by the number of annular plates mounted on each roller; obviously, also in this case, the subjects of each annular plate must be combinable with the annular plates mounted on the other plate rollers.
  • each plate roller will have a width substantially equal to the width of the web material and designs having the same dimension in an axial direction.
  • the number of composite designs different from one another which form the sequence of the sheets S1-S120 is equal to the product of the number of designs of the three plates B, C and D, i.e. of the three plates the extension of which has lengths equal to multiples different from one another of the length L of the single sheet and on which the sequence of designs is not repeated.
  • the plate roller 11A on which there is disposed the plate A, having an extension equal to the plate D and a sequence of three repeated designs, is not included in calculating the number of compound or combined designs that form the sequence of designs on the sheets S1-S120.
  • the overall number of designs different from one another obtained on the finished product before the first design of the series appears again in the print sequence is equal to the product of the length of each plate expressed as multiple of the base length L.
