The present disclosure relates to a process and apparatus for folding and fastening absorbent products of the pre-closed pant type (commonly referred to as “training pants”) which can be used by babies or adults.
Over the last few years, there has emerged interest in diapers of the type commonly referred to as “training pants”. When such a product is taken out of the pack, it already has a conformation that substantially resembles that of a pair of pants. It is put on by sliding it over the legs of the user according to criteria basically similar to the ones adopted for putting on pants.
A training pant typically includes a central portion or region that contains an absorbent core which is designed to absorb the bodily fluids evacuated by the wearer. Side panels extend laterally from the central portion so as to complete the pant-like configuration of the product. The side panels are provided with homologous distal edges designed to be connected (pre-fastened) to one another to form lateral closure regions. In the most recent products the pre-fastened closure regions are intended to be refastenable, thus permitting the product—which is sold in a pre-fastened, closed pant-like condition—to be selectively opened at either side in order to check e.g. whether the product is soiled.
Despite recent developments in equipment and methods for folding and fastening training pants, the various arrangements considered in the prior art have an intrinsic disadvantage in that a separate step of fastening of the side panels subsequent to the step of folding the training pant is typically necessary. This additional step adds to the complexity of plants used for production since the associated manufacturing processes and apparatus are inevitably complex, expensive, and exposed to criticalities in terms of reliability.
It would therefore be desirable to provide a solution that enables the fastening of a training pant directly during the step of folding. Such a solution would enable simplification of the plant for production of the folded training pants since a separate station for fastening of the side panels would not be necessary. The claims are an integral part of the disclosure of the invention as provided herein.
In one aspect, a method of engaging side panels of an absorbent article is provided. The method includes providing a training pant comprising a leading portion, a trailing portion, and a central portion extending in a longitudinal direction between the leading portion and the trailing portion. The training pant further includes a first pair of side panels attached to the central portion proximal one of the leading portion and the trailing portion of the training pant and a second pair of side panels attached to the central portion proximal another of the leading portion and the trailing portion of the training pant. The first pair of side panels each comprises a first fastening region and the second pair of side panels each comprises a second fastening region. The method further includes folding the central portion of the training pant about a transverse axis orthogonal to the longitudinal direction to form a folded training pant. At least a portion of the first fastening regions and at least a portion of the second fastening regions are engaged while the central portion of the folded training pant is received by at least one recessed seat, wherein the at least one recessed seat is located on at least one of a first belt and a second belt of a conveyance system.
In another aspect, an apparatus for preparing a folded training pant is provided. The apparatus includes a conveyance system. The conveyance system comprises a first conveying device comprising a first belt and a second conveying device comprising second belt, wherein the first conveying device and the second conveying device are each configured such that the first belt and the second belt form at least one parallel rectilinear branch. The conveyance system also includes a folding nip, situated between the respective rectilinear branches of the first belt and the second belt and adapted to fold a training pant about a transverse axis orthogonal to a longitudinal direction to form a folded training pant. At least one of the first belt and the second belt further comprises at least one recessed seat configured to receive a central portion of the folded training pant.
In another aspect, an apparatus for preparing a folded training pant is provided. The apparatus includes a training pant assembly system configured to prepare a training pant comprising a leading portion, a trailing portion, and a central portion extending in a longitudinal direction between the leading portion and the trailing portion. The training pant comprises a first pair of side panels attached to the central portion proximal one of the leading portion and the trailing portion of the training pant and a second pair of side panels attached to the central portion proximal another of the leading portion and the trailing portion of the training pant. The first pair of side panels each comprises a first fastening region and the second pair of side panels each comprises a second fastening region. The apparatus also includes a conveyance system comprising a first conveying device comprising a first belt, a second conveying device comprising a second belt, and at least one parallel rectilinear branch between the first belt and the second belt. The conveyance system further includes a folding nip, situated between the respective rectilinear branches and adapted to fold the training pant about a transverse axis orthogonal to the longitudinal direction to form a folded training pant. At least one of the first belt and the second belt also includes at least one recessed seat configured to receive the central portion of the folded training pant.

Process for Folding a Pant Type Diaper
With reference to
The training pant 10 comprises a first pair of side panels 22 attached proximal to the leading portion 14 and a second pair of side panels 24 attached proximal to the trailing portion 18. Both the first pair of side panels 22 and the second pair of side panels 24 are fixed to respective side edges 14 of the central portion 12. The first pair of side panels and second pair of side panels 22, 24 may be fixed permanently to the respective leading and trailing portions 16, 18 of the central body 12, or may be extensions of the topsheet 13 or of the backsheet 15 or of both. Furthermore, one or more of the side panels may further comprise elastic properties.
It is emphasized that the terms “leading” and “trailing” are used herein merely to distinguish the two ends of the training pant 10 from one another and hence do not have specific significance as regards the modalities with which the product is finally worn. For instance, the leading portion 16 may comprise a front waist region or a back waist region. Similarly, the trailing portion 18 may comprise a back waist region or a front waist region. In all embodiments, however, the training pant 10 includes both a front waist region and a back waist region.
The pairs of first and second side panels 22, 24 are provided with respective first fastening regions 26 and second fastening regions 28 that may form a fastening system. In some embodiments, the fastening system may comprise a refastenable fastening system. In other embodiments, the fastening system may comprise a permanently bonded fastening system. For a refastenable fastening system, at least a portion of the first fastening region 26 co-operates with at least a portion of a corresponding second fastening region 28 to form a refastenable lateral fastening. In some embodiments, the first fastening region 26 comprises a first fastening element and the second fastening region 28 comprises a second fastening element. The fastening regions may also comprise a single fastening element or multiple fastening elements. The fastening elements may comprise any recloseable fastening element suitable for refastenably engaging the pairs of first and second fastening regions 26, 28, such as for example adhesive fastenings, mechanical fastenings, or the like.
In one embodiment, the first and second fastening regions 26, 28 are a refastenable fastening system and comprise complementary fastening elements of the hook-and-loop type (e.g., Velcro®), which may be refastenably engaged to one another when the training pant 10 is folded about a transverse axis B of the training pant 10. In some embodiments, the fastening elements may be fixed on respective opposite internal/external surfaces of the respective pairs of first and second side panels 22, 24. In some embodiments, either the pair of first side panels 22 or the pair of second side panels 24 may comprise a pair of fastening elements that are located on the clothes-side of the respective pair of first side panels 22 or the pair of second side panels 24 to form a pair of clothes-side fastening elements. In such an embodiment, the clothes-side fastening elements may be folded inwardly over the central portion 12 of the training pant 10. In this way, the respective fastening elements of the pair of first side panels 22 may be aligned with the pair of second side panels 24 when the central portion 12 of the training pant 10 is folded about a transverse axis B of the training pant 10.
In still other embodiments, the loop fastening elements may be formed by surface portions of the first fastening region 26 or the second fastening region 28. In yet other embodiments, the loop fastening material may be formed by surface portions of the pair of first side panels 22 or the pair of second side panels 24.
The composition of the materials of the training pant 10 is not described in detail in so far as it departs from the scope of the present disclosure. The pant 10 may be produced with any shape, components, or materials known to those of ordinary skill in the art.
The training pants 10 may be formed starting from a continuous composite web that advances in a longitudinal direction A. The composite web may be formed by a continuous succession of semifinished training pants 10 aligned to one another in the direction A. In the continuous composite web, the training pants 10 are oriented in a direction parallel to the direction of movement of the web. The continuous composite web may be cut in a transverse direction to form discrete training pants 10.
For example, a process for manufacturing a training pant 10 is described in detail in PCT Application No. PCT/IB2010/054797, which is incorporated in its entirety herein by reference.
The training pants 10 initially are in a stretched-out configuration and may then be folded about a line of transverse folding B. As used herein, the term line of transverse folding is equivalent to a transverse axis orthogonal to the longitudinal direction of the training pant 10 (“transverse axis”). Subsequent to the folding of the training pant 10 about the transverse axis, the leading portion 16 and the trailing portion 18 may be positioned on top of one another. Once the training pant 10 is converted to the folded training pant 11, the pair of first fastening regions 26 and the pair of second fastening regions 28 are in a condition where they face one another and the pair of first fastening regions 26 and the pair of second fastening regions 28 may be joined together. In some embodiments, once the training pant 10 is converted to the folded training pant 11, the pair of first fastening elements may be connected to the pair of second fastening elements.
It will be appreciated that after the step of folding the training pant 10 about the transverse axis B to form the folded training pant 11, and following the formation of a connection between the homologous pairs of fastening regions 26, 28 the folded training pant 11 assumes the conformation of a garment that may be worn like a pair of pants. In other embodiments, following the formation of a connection between the homologous pairs of fastening elements, the folded training pant 11 assumes the conformation of a garment that may be worn like a pair of pants.
Apparatus for Folding a Pant Type Diaper
The equipment 30 comprises a first conveying device 36 and a second conveying device 38. The first conveying device 36 and the second conveying device 38 have a respective first belt 40 and second belt 42 that are each moved over respective first rollers 44 and second rollers 46. As used herein, the term rollers refers to the pulleys situated in the corners of each conveying device. The first belt 40 and the second belt 42 are moved in the directions indicated by the arrows D and E, respectively. The first belt 40 and the second belt 42 each have at least one respective first rectilinear branch 48 and second rectilinear branch 50 that are situated parallel to one another, thereby forming a folding nip 52.
The first belt 40 and the second belt 42 are configured to pick up by suction respective sections of the training pants 10. To accomplish this result, the first belt 40 and the second belt 42 may be perforated and may be respectively connected to a first suction box 54 and a second suction box 56. The first and second suction boxes 54, 56 may be further connected to a source of negative pressure 58. In some embodiments, the source of negative pressure 58 may be a dynamic vacuum. In other embodiments, the source of negative pressure 58 may be a static vacuum. The first belt 40 and the second belt 42 may each have a respective first branch 62 and second branch 64, each of which face the drum roller 32 and have the purpose of picking up respective sections of the products 10.
The folding apparatus 30 may also be equipped with an insertion blade 60 positioned at the mouth of the folding nip 52 and mobile in the direction indicated by the arrow F to facilitate insertion of the training pants 10 into the folding nip 52. In some embodiments, the insertion blade 60 may facilitate the insertion of the central portion 12 of the training pant 10 into the folding nip 52. In other embodiments, the insertion blade 60 may facilitate the insertion of a midpoint of the central portion 12 of the training pant 10 into the folding nip 52. As used herein, the midpoint of the central portion 12 of the training pant 10 is defined as being located substantially close to the transverse axis B of the training pant 10.
Operation of the folding apparatus 30 is now described. The discrete training pants 10, secured in a spread-out position on the outer surface 34 of the drum roller 32, are brought into contact with both the first branch 62 and the second branch 64 of the respective first belt 40 and second belt 42. In some embodiments, the leading portion 16 of the training pant 10 may be brought into contact with the first branch 62 of the first belt 40 and the trailing portion 18 of the same training pant 10 may be brought into contact with the second branch 64 of the second belt 42. The leading portion 16 and the trailing portion 18 of the training pant 10 may be picked up by vacuum suction by the first and second branches 62, 64 of the respective first and second belts 40, 42, and the central portion 12 of the training pant 10 may be inserted into the folding nip 52. In some embodiments, the insertion blade 60 may push the central portion 12 of the training pant 10 in the direction F to facilitate insertion of the product into the folding nip 52. Each training pant 10 may then move through the folding nip 52 and be folded along the transverse axis B to form the folded training pant 11. The leading portion 16 and the trailing portion 18 of each training pant 10 are positioned on top of one another during the passage of the training pant 10 through the folding nip 52. During folding, the pair of first fastening regions 26 and the pair of second fastening regions 28 may be pressed into contact with one another. In still other embodiments, during folding the pair first fastening elements and the pair of second fastening elements may be pressed into contact with one another.
With reference to
The areas for securing the folded training pants 11 may be provided by the first perforated regions 74 and the second perforated regions 76, which are each configured to secure the folded training pants 10 by vacuum suction. The arrangement of the perforations in the first perforated regions 74 and the second perforated regions 76 may be such as to reproduce the shapes of the respective leading portion 16 and trailing portion 18 of the folded training pant 11. The first recessed seats 66 and the second recessed seats 68 each receive respective portions of the central portion 12 of the folded training pant 11 in which the absorbent core 20 is present. In one embodiment, the pair of first side panels 22 and the pair of second side panels 24 of each folded training pant 11 are arranged on the outside of the respective first recessed seats 66 and second recessed seats 68. In some embodiments, the pair of first side panels 22 and the pair of second side panels 24 of each folded training pant 11 may be situated on the first outer surface 70 and the second outer surface 72, respectively. In some embodiments, the pair of first side panels 22 and the pair of second side panels 24 of each folded training pant 11 may be secured to the first outer surfaces 70 and the second outer surfaces 72, respectively, using vacuum suction. In some embodiments, the first outer surfaces 70 and the second outer surfaces 72 may further include perforations to facilitate vacuum suction.
In a further embodiment, wherein only one of the first belt 40 or the second belt 42 includes respective first recessed seats 66 or second recessed seats 68, at least one of the pair of first side panels 22 or the pair of second side panels 24 of the folded training pant 11 is positioned on the respective first outer surface 70 or the second outer surface 72. In such an embodiment, where the central portion 12 of the folded training pant 11 is situated in a recessed seat located on only one belt, the other belt is configured to situate both the central portion 12 of the folding training pant 11 and the other pair of side panels on the smooth surface of the other belt that is without the recessed seats. Both of the other pair of side panels and the central portion 12 of the folded training pant 11 are secured in position by means of the grip generated by the perforated areas to which vacuum suction may be applied.
In
This apparatus and the method have a further advantage of fastening of the training pants 10 directly during the step of folding. A separate step of fastening of the side panels subsequent to the step of folding is thus avoided. This solution therefore enables simplification of the plant for production of the folded training pants 11 since a separate station for fastening of the side panels is not necessary.
In some embodiments, the movement of the first belt 40 and the movement of the second belt 42 are in phase with one another in such a way that the first recessed seats 66 and the second recessed seats 68 face one another as the respective belts move through the folding nip 52. Moreover, the movement of the first belt 40 and the movement of the second belt 42 are in phase with the rotation of the drum roller 32 in such a way that the central portions 12 of the training pants 10 are inserted into the folding nip 52 in alignment with first recessed seats 66 and the second recessed seats 68.
In still other embodiments, at least one of the first suction box 54 and the second suction box 56 are connected to the vacuum source 58 by a connection system adapted to activate and deactivate the vacuum suction in phase with the movement of the training pant 10.
In another embodiment, the folding apparatus 30 may be configured to handle training pants 10 lacking refastenable elements and may be adapted to form permanent and/or non-refastenable engagement seams between the pair of first fastening regions 26 and the pair of second fastening regions 28. In some embodiments, opposing sealing rollers (not shown) may be incorporated into at least one of the first conveying device 36 and the second conveying device 38. In some embodiments, the opposing sealing rollers may form the folding nip 52. In other embodiments, the opposing sealing rollers may be situated at a location downstream of the folding nip 52. In still other embodiments, the opposing sealing rollers may be aligned at locations transverse to the machine direction and corresponding to the desired location of the sealed engagement seams. In yet other embodiments, the opposing sealing rollers may provide sufficient pressure and/or heat to create a non-refastenable engagement seam between the pair of first fastening regions 26 and the pair of second fastening regions 28. In other embodiments, alternate means may be employed for producing non-refastenable engagement seams, including but not limited to ultrasonic bonding, hydroentangling, adhesive bonding, and the like.
In certain embodiments, the sealing rollers may be configured to be removable from the folding apparatus 30 so that the folding apparatus 30 may be capable of selectively and alternately producing refastenable and non-refastenable training pants with minimal modification to the production line and minimal machine down time. Accordingly, the folding apparatus 30 may be operable with or without the sealing rollers being present.
Of course, without prejudice to the underlining principles of the invention, the details and embodiments may vary, even significantly, with respect to what has been described and illustrated herein merely by way of example, without departing from the scope of the invention as defined by the annexed claims.
This application claims priority to U.S. Provisional Patent Application No. 61/453,677 filed on Mar. 17, 2011, the disclosure of which is incorporated in full herein by reference.
