Definitions

  • the present invention relates to a rewinding method in a rewinding machine for making logs of sheet or web material, for example used for the production of rolls of toilet paper, rolls of all purpose tissue paper for household use, non woven fabric, paper industrial rolls and the like.
  • the invention relates to a rewinding machine that carries out this method.
  • Rewinding machines where the winding step takes place in a special winding zone comprising an upper roller, a lower roller and a pressing roller.
  • glue distribution devices of different kind can be used.
  • nozzles connected to the structure of the rewinding machine can be used that spray a measured amount of glue on the core before that the core enters the movable cradle to start winding.
  • Other devices can be also used such as distributing brush means or knives.
  • a special separation finger is provided brought into rotation at an angular speed higher than the winding roller about which the web of paper adheres, causing therefore the tearing of the paper. Then, a speed difference of rotation between lower roller and pressing roller causes the exit of the formed roll.
  • a special cutting blade creates a clean cut on the web without any need of auxiliary devices such as the separation finger above described.
  • Said glue distribution systems have drawbacks on final quality of the product.
  • the glue put on the tubular core of cardboard can cause large droplets of glue to wet the web of paper during the contact of the core with the roller, in such a way that the roller is dirtied and the paper is wound about the upper roller instead of the core.
  • the glue can dry loosing its effect. This would cause a maintenance stop to the machine for removing the core and putting in a new one, with high loss of time and production rate.
  • the formed log leaves the rewinding machine and is sent to a machine adapted to glue the free end.
  • the methods of gluing this free end are many and in any case need an additional gluing section of the machine. For example, by air specially directioned jets, the free end of the formed log is stretched on a support plane. Then, gluing systems spread glue for all the length of the free end sticking the latter on the final log.
  • the free end gluing unit, as well as the gluing step of the starting ed of the log create relevant problems.
  • the free end cannot be precisely stretched on a support plane, being this responsive to the direction of the air jets. Therefore the final closure is often faulty, with presence of large wrinkles and, in particular, of free end portions folded on themselves.
  • the glue is applied directly on the core in the cradle by means of two gluing guns.
  • the synchronization of the two gluing guns can lay glue on the core in predetermined instants such that the rotation of the core same transfers the glue by contact on the web of paper upstream and downstream of the desired tearing line.
  • this system is not much reliable, since a slip of the core and therefore a subsequent loss of rotational speed of the core causes an incorrect distribution of the glue causing, for example, the free nend not to stick to the roll, or in particular, a faulty start of the new winding cycle.
  • a feature of the present invention to provide a rewinding machine that substantially prevents residual glue from entering between the mechanical moving parts jeopardizing the correct operation and damaging the machine as occurs in the rewinding machines of prior art.
  • a rewinding machine for making logs of sheet or web material, for example used for the production of rolls of toilet paper, rolls of all purpose tissue paper for household use, non woven fabric, paper industrial rolls and the like, comprising:
  • the measured amount of glue can be applied only downstream of the perforation and/or clean cut transversal line, i.e. on the portion of the web of paper corresponding to the formed log tail end to allow closing the log once removed the formed log after cutting or tearing the web of paper.
  • the measured amount of glue can be applied upstream from the perforation and/or clean cut transversal line, i.e. on the portion of the web of paper corresponding to the head end of the new log that is brought to stick on a corresponding core once removed the formed log, after cutting or tearing the web of paper.
  • the portion of said web of paper on which the measured amount of glue is applied can be arranged bridging the perforation and/or clean cut transversal lines.
  • means can be provided for measuring the length of the web starting from a large roll of paper operatively connected to the means for applying. More in detail, the means for measuring operate the means for applying the measured amount of glue to achieve a measured length of the web of paper.
  • the means for applying are movable towards/away from the web of paper operated by an actuator selected from the group comprised of:
  • a rewinding machine for making logs of sheet or web material, for example used for the production of rolls of toilet paper, rolls of all purpose tissue paper for household use, non woven fabric, paper industrial rolls and the like, comprising:
  • a rewinding method for making logs of sheet or web material, for example used for the production of rolls of toilet paper, rolls of all purpose tissue paper for household use, non woven fabric, paper industrial rolls and the like, comprising the steps of:
  • a winding method for making logs of sheet or web material, for example used for the production of rolls of toilet paper, rolls of all purpose tissue paper for household use, non woven fabric, paper industrial rolls and the like, comprises the steps of:
  • a rewinding machine of a web 1 for making a log 2a comprises a feeding roller 3 of web 1 and, downstream of it, a winding cradle 4 at which the production is made of log 2a for winding the web of paper 1 about a core 20.
  • the latter is supplied into cradle 4 by suitable introduction means, for example a loading unit that draws the cores 20 from a chute guide, not shown in the figure.
  • the cradle 4 comprises a upper winding roller 5, a lower winding roller 6 and a pressing roller 7. The latter follows the growth of the log 2 with the task of assuring its continuous contact with the winding rollers 5 and 6 controlling its diameter growth.
  • a perforation roller 11 3 is provided that acts in combination with a counter-roller 12 to provide a plurality of transversal perforation lines 15 on the web of paper 1 defining a plurality of panels 16.
  • a cutting roller 10 can be provided.
  • the latter can work in combination with the upper winding roller 5 for carrying out a clean cut on the web of paper 1 whenever a number of panels 16 is obtained corresponding to a complete log.
  • By cutting the web of paper 1 two free ends are generated corresponding to the tail end 1a for log 2a formed and at the head end 1b for log 2b.
  • the separation of log 2a and 2b is made at determined perforation lines 15. This is made regulating, as well known, the relative speed of the winding rollers 5, 6 and 7. Even in this case, the separation made at the perforation line 15 generates a tail end 1a for formed log 2a and a head end 1b for new log 2b.
  • upstream from the means for introducing the core 20 means are provided 50 for application of a measured amount of glue 55 on a determined portion of the web of paper 1.
  • the means for applying 50 can, for example, provide a screened roller 51 on which a measured amount of glue is periodically spread by a spreading blade 56 for example equipped with a duct 57 through which the glue is supplied.
  • Upstream from the feeding roller 3 means can be provided for measuring the unwinding steps of the web of paper 1 starting from a large roll not shown in Fig. advantageously.
  • the latter is operatively connected to the means for perforation in order to operate them to provide the perforation lines 15 at predetermined distances, by cutting roller 10, if it is present, to allow separating two consecutive logs, and with the means for applying 50 in order to operate them for applying a determined amount of glue at predetermined perforation lines 15.
  • the means 50 for application are provided movable from a first position, where the screened roller 51 is distant from the web of paper 1 ( Fig. 1 ) to a second position, where the roller 51 is next to the web of paper 1 for applying a layer of glue 55 at predetermined portions of the web 1 ( Fig. 2 , 5 , 8 , 11 , 12 , 13 ).
  • the screened roller 51 can be operated in the movement towards/away from the web of paper 1 by a hydraulic, or pneumatic, or electric actuator.
  • the layer of glue 55a is mounted by the screened roller 51 only at portion 18 of the web of paper 1 arranged downstream, to determine perforation lines 15'.
  • the perforation line 15' corresponds to the perforation line at which the cutting roller 10 cuts the web of paper 1 separating it into the tail end 1a of the formed log 2a and head end 1b of the new log 2b.
  • the tail end 1a of the log 2a has the layer of glue 55a for stopping the formed log 2a.
  • a layer of glue 53 can be previously applied, for example by a nozzle sprayer 52 arranged between the feeding means of the core 20 and the cradle 4.
  • the core 2b with the layer of glue 53 is put into cradle 4 and then approached to the web of paper 1 when the portion 17 arranged upstream from the perforation line 15' reaches it.
  • the approach of the core 2a to the web of paper 1 can be made, for example by a rotation about axis 19 of the cradle 4 operated by an actuating rod 9.
  • the roller 51 applies the layer of glue 55 in the only portion 17 of the web of paper 1 arranged upstream from the perforation line 15'.
  • the portion 17 of the web of paper 1 on which the layer of glue 55b is mounted corresponds, in this case, to the head end 1b that is made by the cut carried out at the perforation line 15' by the cutting roller 10 ( Fig. 6 ).
  • the layer of glue 55b allows at the head end 1b sticking with core 20b put in cradle 4 when this approaches the winding roller 5, as described for the previous case. This way, winding the web of paper 1 about core 20b is started forming a new log 2b.
  • the tail end 1a of each log at the exit of the rewinding machine can be then connected to the relative log by a gluing machine of traditional type arranged downstream of the rewinding machine not shown in the figure.
  • roller 51 can be also operated for applying a layer of glue 55 both on the portion 17 and on the portion 18 of the web of paper 1 at the perforation lines 15'.
  • the roller 51 is firstly approached to the web of paper 1 at the portion 18 where a first layer of glue 55a is applied, then arranged according to the withdrawn position 50a (dotted line) at the perforation line 15', and again approached to the web of paper 1 at the portion 17 for applying a second layer of glue 55b.
  • both the tail end 1a of the formed log 2a and the head end 1b of the new log 2b, obtained by cutting the web of paper 1 through cutting roller 10 ( Fig. 9 ) have respective layers of glue 55a and 55b. This allows to glue both to the tail end of formed log 2a and the head end of the new log 2b, avoiding then the use of other gluing systems.
  • a same result, with possibility to use also a glue of different type, can be obtained using two different screened rollers 51a and 51b, as diagrammatically shown in Fig. 11 .
  • the glue 55 both on the portion 17 and on the portion 18 of the web of paper 1, it is enough to operate at the same time the screened rollers 51a and 51b working in corresponding positions of the rewinding machine, or operating only one in two consecutive instants.
  • roller 51 applies the layer of glue 55 bridging the perforation lines 15. Even in this case it is possible to stop both the tail end 1a on the formed log 2a and starting winding the new log 2b on the core 20b by sticking it with the head end 1b.
  • FIG. 13 an exemplary embodiment is shown that provides arranging the screened roller 51 at the cradle 4.
  • the layer of glue 55 can be mounted by roller 51 downstream of the perforation line 15.
  • the rewinding machine above described assists remarkably the production process for the log of paper. In fact, it avoids the need of using expensive and bulky gluing machines usually arranged downstream of and upstream from the machine to provide respectively the application of glue on the cores and on the end portions of the formed log.
