Definitions
- the present invention relates to packaging methods and machines, used to package products.
- Some packages where products are packaged are generated from sheets, which are shaped to provide them with a tubular shape, acting on the shaped tube tube as appropriate to generate the package.
- a longitudinal seal of the longitudinal ends of the sheet is also required, in order to close the tube longitudinally.
- seals and transverse cuts are made in the tube to obtain closed containers at both ends.
- the product to be packaged is introduced into the tube. Normally, in each sealing and cross-cutting operation two closures are obtained: a first closure for the tube on one side of the cut, which will be a first closed end of a container generated below; and a second closure on the other side of the cut. The second closure closes the other end of a container closed by the first closure in the previous operation.
- Patent document US20160272349A1 discloses a vertical packaging machine for packaging products, wherein the package is generated from a continuous sheet.
- the sheet is shaped to give it a tubular shape, and is sealed longitudinally to generate a sheet tube.
- the tube is dragged in a direction of vertical advance, and two reinforcements are generated on each side of the tube during said drag.
- the machine comprises actuation means on each side of the tube, which fold said tube inwards in opposite sides of the same as it advances in the direction of advance, generating a longitudinal reinforcement on each side of each fold.
- a cut and seal is made transverse to the direction of advance in the tube, in a certain way and by means of a K-shaped tool that also performs an additional fold in the area of the tube that cuts and seals , said additional fold being used to reinforce the bottom of the resulting container.
- a piece of sheet is removed from each side of the tube, a piece that is discarded, to facilitate the subsequent operation of the K-shaped tool.
- the object of the invention is to provide a method and a packaging machine, as defined in the claims.

- the tube is fastened transversely to the direction of advancement to one side of the part of the tube to be folded with respect to the direction of advancement, and during the folding of the tube a tube is generated partial lateral rupture in the folding direction, between the part of the tube contacted to be folded and the subject part of the tube, the tube being sealed on both sides of the partial lateral rupture and said tube being cut at the height of the partial lateral rupture during sealing and cutting stage, the folded part remaining in the container and / or in the closed tube, depending on how and on which side with respect to the direction of advance the tube is held transversely.
- This breakage allows, thanks to the tension to which the tube is subjected with the clamping, the part of the tube between it and the subject part returns to its previous form before folding, if it had been affected by the folding, or to maintain its shape without being affected by the folding. Thanks to the breakage and the recovery of the form, in addition, the sealing corresponding to one of the ends of the container (or at least part of it) is carried out on an area of the wrinkle-free tube, for example, obtaining after sealing a straight welding, in the style of pad-type packaging, without crease or wrinkles in said area, and the sealing of the opposite end of the adjacent container that is sealed simultaneously in the same stage is performed on the folded area of the tube, obtained after the sealed one end of said container adjoining the style to that of the Doy-Pack or stable bottom containers, for example.
- the packages obtained from the proposed method can thus comprise, due to folding, a crease at least on one side of one end, and a smooth seal, without crease, on the same side of the other end.
- containers of the Doy-Pack type or with a stable bottom can be manufactured, among others, without the need to make additional folds as occurs in the state of the art. In this way a saving in the amount of sheet to be used for a container of the same characteristics is achieved.
- the packages obtained from the proposed method comprise a greater storage volume for the product to be packaged than the Doy-Pack or stable bottom containers obtained in the prior art, due to which allows to avoid folds at one of its ends, while the contiguous end may comprise a weld with a crease style to that of the Doy-Pack or stable bottom packages.

- a first aspect of the invention relates to a packaging method for a packaging machine 100, as shown partially and by way of example in Figure 1, in which a sheet tube 10 generated from a continuous sheet is supplied in one direction of advance A, and packages E are generated from said tube 10.
- Figures 2 to 6 show, by way of example and schematically, different steps during the execution of a preferred embodiment of the method.
- the method may comprise a forming step in which the tube 10 is generated from the corresponding sheet, for example by welding the longitudinal sides of the sheet together.
- the method also includes at least the following stages:
- a subsequent sealing and cutting stage in which a tube 10 is obtained closed at one end upstream in the direction of advancement, and downstream in said direction of advancement A a container E is obtained closed at both ends and separated from the tube 10 .
- the tube 10 is fastened transversely to the direction of advance A, preferably to one side of the part of the tube 10 to be folded with respect to the direction of advance A, and during folding the tube 10 generates a partial lateral break R in the folded direction T between the part of the folded tube 10 and the clamped part of the tube 10, the tube 10 being sealed on both sides of the partial lateral break R and said tube 10 being cut at the height of the partial lateral rupture R during the subsequent sealing and cutting stage, the part being folded in the container E and / or in the closed tube 10, depending on how and on which side with respect to the direction of travel A the tube 10 is held transversely.
- the rupture R that is generated is partial, in the sense that it does not separate the tube 10 into two parts.
- the container E thus obtained thus comprises a fold P2 and / or P1 at least on one side of one end, and a smooth seal, without a fold, on the same side of the other end.
- the tube 10 once attached, in the subject area (and in the vicinity) is transformed into two superimposed sheets, acting on said superimposed sheets from one side thereof in the folding stage, in the direction of folding T, and generating the break R from one side of said overlapping sheets (hence it has been called “lateral" breakage).
- This break R allows the part of the tube 10 between the break R and the clamp to "become independent" of the folding caused on the tube 10, such that said part is either not affected by the folding or recovers its pre-folding form if it had been lost due to said folding.
- the sealing and cutting stage is subsequent to the folding stage, in the sense that it begins after the folding stage begins, but it can begin without having finished said folding stage or once said folding stage has ended.
- the sealing and cutting stage begins in any case once the part of the tube 10 between the rupture R and the subject part returns to its previous form before folding, if it had been affected by the folding, thus ensuring the sealing in a smooth part, without folds, of tube 10.

- a correct generation of the weakness line 5 is ensured, since while the tube 10 is generated it remains attached, tensioned, and does not move with respect to the device responsible for making the weakness line 5.
- the part of the tube 10 additionally held is released, see figure 4, and the folding step is carried out maintaining only the first support.
- the weakness line 5 is generated by a device that is arranged in a first position to generate said weakness line 5 and in a second position to generate the cross-section of the tube 10.
- three parts of the tube 10 can also be actuated by contact: two facing parts and another part separated from one of the two in the forward direction A.
- a single line of weakness is generated 5 next to and next to one of the parts actuated in the direction of advance A, and the first fastener does not cover the entire transverse width of the tube 10, but is made only to one side in the direction of advance A of the associated actuated part to line of weakness 5, resulting in a container E with three folds P1, P2 and P3, as shown by way of example in Figure 12c.
- the container E thus obtained comprises, therefore, due to folding, a fold P2 at least on one side of one end, and a smooth seal, without fold, on the same side of the other end.
- the folded part remains both in the container E (folds P1 and P2) and in the closed tube 10 (folded P3).

- the cutting tool 104a thus comprises a first cutting profile 104a1 configured to generate the line of weakness 5 and a second cutting profile 104a2 configured to cross-section the tube 10, as a saw, and the control device is configured to move the cutting tool 104a to a first position in which the first cutting profile 104a1 of said cutting tool 104a contacts the tube 10, and a second position in which the second cutting profile 104a2 of said cutting tool 104a contacts the tube 10.
- the control device causes the additional clamping device 107 to release the part of the tube 10 that it held (see figures 4 and 9), and in that situation, it causes the action of actuation device 103 (see figures 5 and 10).
- the sealing and cutting device 104 causes the tube 10 to be sealed on both sides of the break R in the direction of travel A, shown in Figure 1 1, and the cross-section of the tube 10 preferably at the height of the break R
- the sealing and cutting device 104 comprises a sealing tool 104b, which generates a first seal on one side of the break R in the direction of travel A and a second seal on the other side of said break R, performing the cross section between both seals.
- the cutting tool 104a is connected to the sealing tool 104b with freedom of movement orthogonal to the direction of travel A (towards the tube 10 and away from the tube 10).
- the packaging machine 100 comprises an actuation device 103 that is configured to act by contact on three parts of the tube 10 simultaneously: two facing parts and another part on the opposite side of the sealing and cutting device 104, distanced from one of the previous two in the direction of advance A.
- the packaging machine 100 is configured to generate a single line of weakness 5 near and next to one of the parts actuated in the direction of advance A, and the clamping device 106 is configured not to cover the entire transverse width of the tube 10, but holds only the side comprising the line of weakness 5 and on which the actuating device 103 acts in a single contact zone, resulting in to a container E with three folds P1, P2 and P3, as shown by way of example in Figure 12c.
- the packaging machine 100 may comprise additional elements for incorporating easy-opening or re-closing elements, such as a zipper Z in the tube 10, resulting in a container E with this type of closure in one of its ends as shown by way of example in Figure 12b.
- the packaging machine 100 is adapted to generate the containers E that have been discussed with reference to the method, thus being at least the actuation device 103 and the clamping device 106 adapted or configured as appropriate in each case.
