Definitions

  • the present invention relates to an apparatus for joining two or more plies of tissue paper, for producing interleaved items, particularly facial tissues.
  • paper tissues of the type commercially known as tissues or facial tissues are generally constituted by two or more plies, normally two, three or four plies.
  • the decorative patterns of products of the known type are provided by means of a pair of steel rollers of the male-female type or point to point rollers.
  • This ply joining system is more expensive than the system with contrast roller and knurling tools, since steel-on-steel rollers or point to point rollers require precision in their scoring and suitable diameters in order to reduce the flexing that would compromise the joining of the plies. Even in the roller system, joining in fact occurs due to the pressure that the two scored rollers apply to the paper.
  • a further drawback of the roller joining system is constituted by the fact that in order to change the decorative pattern it is necessary to replace the rollers, with consequent long tooling times.
  • US5433817 discloses a ply-bonding device for paper converting machines comprising a support to which a movable unit is pivoted.
  • the movable unit is provided with a pressure wheel which cooperates with a counter-roller, and a pressure means which forces the wheel against the counter-roller.
  • the wheel is resiliently supported on the movable unit and, during operation, the position of the unit is defined by an abutment on the support.
  • the movable unit is pivotally supported on a plate having a handle. A plurality of spaced-apart plates are mounted on a beam. Each pressure wheel can be removed from the movable unit.
  • the ply-bonding device further includes a brush which keeps the surface of the wheel clean.
  • EP1533112 discloses an apparatus for manufacturing multiple-ply paper products by knurling, having a knurling wheel unit constituted by one or more knurling wheels, each of which cooperates with a contrast roller in order to decorate by knurling a paper ply and in order to decorate and join at least two paper plies.
  • Each knurling wheel is provided with relief patterns arranged so that despite appearing to be separate they allow the knurling.
  • the knurling wheels may be supported by a single supporting shaft or individually by a holder for each knurling wheel. Each knurling wheel may be removed from its holder only after the holder is removed from the supporting beam.
  • US2002/0148578 discloses a device for applying an embossing to a web of tissue paper comprising a full width anvil roller and a plurality of small width embossing rollers which are rotationally movable around rotational axes which run parallel to the rotational axis of the anvil roller.
  • the embossing rollers can be individually positioned against the anvil roller.
  • Three embossing rollers are mounted on a unit comprising a bracket, which serves to mount the unit to a girder of the machine frame, and a frame element which is pivotally attached to the bracket via a pivot pin and holds the shaft of the embossing roller.
  • the individual embossing rollers may be substituted by removing and disassemble the entire unit.
  • the aim of the present invention is to provide an apparatus for joining two or more plies of paper that overcomes the drawbacks of the cited prior art.
  • an object of the invention is to provide an apparatus that allows to modify the decorative pattern produced during the joining of the plies more rapidly and easily than traditional systems.
  • Another object of the invention is to provide an apparatus that is cheaper than the prior art apparatuses.
  • the apparatus includes at least one station 2 for joining two or more plies of tissue paper; the station 2 has a contrast roller 3 and a set of embossing wheel units 4 that act on the contrast roller 3.
  • the embossing wheel units 4 are anchored to a supporting beam 16, which extends parallel to the contrast roller 3 and includes a pneumatic means adapted to push the embossing wheel units against the contrast roller 3.
  • the pneumatic means is constituted by an inflatable hose 17.
  • Each embossing wheel unit 4 is constituted by a wheel 5 that is pivoted in a support 6 which in turn is associated with the frame of the apparatus 1.
  • the embossing wheel units 4 are mounted on the supporting beam 16 so that they can be replaced easily by removing the wheel 5 from the support 6 or by disassembling the support itself.
  • a support 6 which is constituted by a bracket 7 that is pivoted in a block 8 by means of a pivot 9.
  • the support 6 includes a pair of fixing screws 10 and 11.
  • Each wheel 5 is provided with protrusions which form a decorative pattern and are adapted to deform the plies of tissue paper in contrast with the contrast roller 3.
  • the embossing wheel units 4 are anchored to the supports so that they can be easily replaced by disassembling the wheels 5 or by replacing the supports complete with the rollers.
  • the wheels 5 and the contrast roller 3 are advantageously made of hardened steel with adequate hardness.
  • the joining of the plies occurs by deformation of the paper that passes between the decorative wheels 5 and the contrast roller.
  • each wheel form a decorative pattern 14 and at the same time join the plies of tissue paper.
  • the decorative and joining lines thus formed produce a series of rows of tissues in the direction of advancement of the plies of tissue paper.
  • the plies of tissue paper are then cut longitudinally along a cutting line 15 that is extended in a central region of the decoration 14.
  • the number of embossing wheel units 4 is a function of the width of the tissue paper 13 being unwound.
  • the width of the tissue 13 normally varies from 100 to 300 mm; in the specific case, a tissue 13 is shown which has a width of 210 mm, while the width of the spool is 2780 mm, from which 25+25 mm of trim must be removed, obtaining thirteen rows of 210-mm tissues, so that the number of embossing wheel units 4 is fourteen, since each assembly joins and decorates two adjacent plies or a trim + tissue.
  • the apparatus according to the present invention allows to provide products of various kinds.
  • Figure 6 is a view of a product obtained by means of the apparatus according to the present invention, which has decorations 14 on both edges.
  • Each embossing wheel unit can in fact be removed from the respective support and replaced easily, without necessarily disassembling the support from the frame as well.
  • the present apparatus allows to avoid the long tooling times required to change the decoration of the edges when using traditional systems for joining by means of steel-on-steel rollers.
  • Another important advantage of the present invention is the reduced cost of the decorative embossing wheel units with respect to steel-on-steel rollers of traditional systems.
