Definitions

  • the present invention refers to the technical field of machinery for the production of paper and similar products.
  • it refers to an innovative embossing roller suitable to emboss sheets with different designs in sequence.
  • the embossing is realized by means of a pair of opposed rollers provided with micro-protuberances or incisions perfectly complementary among them and that reproduce a certain design.
  • the continuous plies of paper, passing through the pair of rollers during all the production cycle, are therefore imprinted, thus remaining closely attached among them thanks to the punching action of the micro-protuberances that penetrate among the plies attaching one to the other closely.
  • the ply coming out of the rollers is therefore a single continuous paper tape that plots the design of the embossing.
  • the paper tape coming out from the embossing section then goes into a specific machinery, such as an interfolding machine or a rewinder machine, with the aim of realizing the finished product.
  • a specific machinery such as an interfolding machine or a rewinder machine
  • the existing embossing rollers are anyway configured so as to imprint the paper tape in a continuous manner but tracing out always the same design within an area of the paper tape delimited by the "cut off" length or rather cut length or perforation length of the paper tape. In such a way, when the product is finished, all panels that constitute, for example, a kitchen roll or indifferently a facial tissue or hand towel will always reproduce the same design.
  • the roller (1) comprising a plurality of micro-protuberances distributed in correspondence of its outer cylindrical surface and destined in use to emboss a paper tape (2).
  • the roller (1) has an outer circumference which length C is a multiple of the cut off length L of the tape.
  • each sector comprises its own specific pluralities of micro-protuberances distributed on its surface so as to define on each one of them a specific design Dn.
  • the roller cyclically imprints the tape according to a sequence corresponding to the designs Dn, each of which is destined to be printed within an area of the tape delimited by the cut off length L.
  • the paper tape is cyclically imprinted with different designs which, if the phase of the roller and the tape cut off are duly regulated, will rest within each single panel.
  • the result will be therefore that of a product cyclically reproducing panels with different embossing ornaments.
  • the embossing roller (3) can be coupled in use to a complementary embossing roller and configured to be installed in such a manner in correspondence of an embossing section relative to an interfolding machine.
  • the embossing roller can be coupled in use with a complementary embossing roller and configured to be installed in use in an embossing section relative to a rewinder machine.
  • the embossing roller (3) can also be coupled in use with a complementary rubber roller and configured to be installed in an embossing/gluing section of an interfolding machine or in a rewinder machine.
  • the roller comprises rotation means to allow the connection of same in a rotating manner to a specific support of the embossing or embossing/gluing section.
  • Motorized means to rotate said one or two coupled rollers continuously at a predetermined programmable embossing speed are further provided, for example an electrical motor.
  • This means can be for example of the hydraulic or mechanic type.
  • a paper towel kit for hygiene purposes comprising a case (4) and a plurality of sheets (5) of embossed or embossed/glued type, wherein said sheets are prearranged piled up inside said case so that they can be taken out individually and characterized by the fact that the sheets reproduce in a cyclic manner an embossing sequence of designs Dn obtained with at least one roller in accordance with what has been described.
  • the designs Dn of the sequence are different one from the other.
  • the sheets are sheets of interleaved "facial" type.
  • each one of said sheets is constituted of at least two plies embossed and sized between them.
  • an embossing roller 3 is schematized according to the prior art.
  • Figure 2 for clarity purposes, indicates two rollers coupled in an embossing section so as to create a passage gap between them through which two or more plies of paper are joined in a single tape 2 coming out.
  • the tape has a transversal length H substantially equal to the comprehensive length of the embossing rollers so that these can emboss the entire area of tape during its passage in the advancement direction according to the arrow indicated in the figure.
  • Figure 3 represents an embossed tape 2 with the aim of evidencing a plurality of "cut off" lengths L, all equally distanced among them longitudinally along the entire length of the tape.
  • the cut off line is a transversal clear cut line or a transversal line comprising a plurality of perforations depending on the product that the tape will constitute.
  • the tape coming out of the embossing section enters a rewinder machine
  • this is provided with perforating rollers so as to perforate transversally at pre-defined intervals of length L all the width H of the tape as this is reeled around a carton core.
  • the log produced is cut in appropriate cut section in kitchen rolls or the like to be then launched to the market.
  • the roll is therefore constituted of paper of a pre-established measurement reeled around the core and provided with said tear off lines at a pre-established distance L distanced one from the other so that the final user can from time to time tear off a panel, or sheet, from the reeled tape.
  • the tape coming out of the embossing section can go inside an interfolding machine in general.
  • the cut off represents a clear cut line.
  • the tape fed within the machine is cut in panels of comprehensive length L and then interfolded according to known forms (for example, V or Z forms).
  • Figure 5 represents the final log of interfolded product which is then size cut (length T of figure 5 ) in an appropriate gang-saw machine to be then packaged in appropriate cases.
  • C NxL
  • figure 6 represents, absolutely in a non limiting manner, a plan development of such circumference with the aim of comparing its length C with a paper tape 2 reproducing the cut off length L of the product to be made.
  • the example chosen indicates a circumference C which length is four times that of the cut off of the product.
  • different multiples of four can be used without moving apart from the present inventive concept. During a complete rotation of the roller, therefore, this will imprint a length of tape that coincides with four times the length of cut off, or rather 4L.
  • the embossing roller (only in the case of a circumference C four times long the cut off L) is realized in such a way that it is provided with four corresponding circular sectors C 1 , C 2 , C 3 and C 4 , all of them of equal length among them and therefore that substantially coincide with the cut off length L.
  • each sector is therefore provided with a plurality of micro-protuberances such as to define, for each sector, a different design Dn.
  • figure 8 details a plan development of the circumference C of comprehensive length that coincides in this case with 4xL, so as to mark with different background colours the four different designs D 1 , D 2 , D 3 , and D 4 defined by the embossing micro-protuberances.
  • Figure 8 also represents a perspective view of such roller. It is naturally evident how any number N of sectors Cn can be realized depending on the length C of circumference, along with combinations of embossing designs practically infinite, without moving apart from the present inventive concept.
  • Figure 9 represents an example of functioning of a roller with four sectors, even if, as already stated, any number of sectors can be chosen.
  • the figure therefore shows the passage of the paper tape 2 between the rollers 1 and the consequent imprint of same, realizing an equivalent sequence of designs from D 1 to D 4 on the tape each of which is printed within the area of cut off.
  • the figure naturally shows the cyclic nature of the designs reproduced on the tape.
  • Figure 10 represents the case of an interfolded product of "facial" type embossed and in this case also glued in accordance with the present invention.
  • a case 4 contains the interfolded sheets 5 according to a sequence 6, 7 and 8 which reproduces the relative sequence of designs D 1 , D 2 and D 3 of the sectors present on the embossing roller.
