Definitions

  • the present invention relates to a method for manufacturing belted disposable absorbent garments, the method including securing a belt to a production web comprising further garment components.
  • the invention is also concerned with a belted disposable absorbent garment such as a diaper made by said method.
  • the belted disposable absorbent garments according to the invention are made to carry an absorbent either as an integrated absorbent core or as a separate absorbent insert placed and preferably attachable inside the garment.
  • Belted disposable garments which are arranged to carry an integrated absorbent core or a separate absorbent insert are generally known in the art. These garments are particularly useful for adult incontinent wearers and especially for wearers who wish to be able to apply the garment to themselves.
  • a belted disposable absorbent garment is easier to apply to a wearer who is standing up than the diapers which are commonly used for infants and which are closed at the sides by means of tape tabs.
  • One example of a belted incontinence garment is described in EP 1 049 438 in which an absorbent chassis is provided with belt webs on both sides of a first longitudinal end.
  • the belt webs are intended to be connected to each other by fastening around the waist of the wearer while the chassis portion hangs down between the legs of the wearer. Once the belt webs have been joined together, the wearer can then reach between his or her legs to draw up the absorbent chassis between the legs and to attach the free end of the absorbent chassis to the belt that is formed by the connected belt webs.
  • belted disposable absorbent garments such as belted diapers involves somewhat different considerations from those associated with the production of conventional open-type diapers that are closed at the sides by means of adhesive or mechanical fastening tabs.
  • the belt or belt parts are considerably longer than conventional fastening tabs so that the belt parts may move and flap in an uncontrolled manner during production. This may cause the belt parts to be damaged by unintentional folding, wrinkling, tearing or by being cut by mistake when separating individual articles from the production line.
  • the objects of the invention are therefore to provide an improved releasable transport attachment on the belt parts of a disposable absorbent garment and to provide an improved manufacturing process for belted absorbent articles.
  • the invention relates to a method for manufacturing a belted disposable absorbent garment, the method comprising joining together garment components comprising chassis components and belt arrangements, thereby forming a production web of interconnected garment blanks, the production web being continuously moved in a machine direction MD and having a cross machine direction CD perpendicular to the machine direction MD.
  • the side edges of the production web are arranged in the MD.
  • Each garment blank comprises one belt arrangement being permanently attached to the garment blank in a garment waist-forming area of the garment blank, and having a main extension of the belt arrangement in the cross machine direction, CD of the production web and having first and second belt parts of the belt arrangement extending from the side edges of the production web.
  • the method comprises severing the production web in the CD, between individual garment blanks, after joining of all garment components to the production web.
  • the method is characterized by the belt parts being placed in a configuration where they are overlapping with the production web and with each other and with the first belt part being placed over the second belt part.
  • the first and second belt parts each have a first side edge in the cross machine direction CD and a second side edge in the CD, the first side edges of the first and second belt parts being leading edges in the MD of the production web and the second side edges of the first and second belt parts being trailing edges in the MD.
  • the method further involves joining together the overlapping portions of the first belt part and the second belt part with at least two spaced-apart releasable attachments placed at a distance of 0-15 mm, preferably at a distance of 5-10 mm from the first side edge of the first belt part and of the second belt part and joining together the overlapping parts of the second belt part and the production web with at least one releasable attachment spaced from the first and second side edges of the production web and being placed at a distance of 0-15 mm, preferably at a distance of 5-10 mm from the first side edge of the second belt part.
  • the distance of the releasable attachments from the side edges of the belt parts is measured as the shortest distance between and edge of each bond element and the respective side edges.
  • a finished disposable absorbent garment according to the invention may comprise a chassis having at least a liquid impermeable backsheet and a liquid permeable topsheet.
  • the chassis also comprises leg elastic elements.
  • An absorbent core may be integrated with the chassis and may be placed between the topsheet and the backsheet. However, an absorbent core may alternatively be part of a separately produced and provided absorbent insert.
  • the method of forming the garment according to the invention comprises incorporating a fastening belt with the production web.
  • a production web as used herein is a compound web comprising multiple components of which at least one component is a continuous material web such as a topsheet web or a backsheet web that acts as a carrier web for the other components that are joined to form the production web.
  • the production web is a combination of all components that are used to form the finished disposable absorbent garments.
  • Another way of considering the production web is as a running web of garment blanks being continuously more complete as new components are added to the production web when it is moved along the production line. Each garment blank will eventually form a disposable garment after all components have eventually been joined to the production web and the production web has been severed between the garment blanks to separate the individual disposable garments form the production web.
  • transport attachments are made at selected locations on the belt arrangements with minimal amount of bonding while maintaining the belt parts in a correct position throughout the manufacturing process.
  • the releasable transport attachments hold down the leading edges of the belt parts against the production web as the production web is moved in the MD.
  • the belt parts are prevented from being lifted by the flow of air created by the moving production web and from being displaced in a rearward direction. Lifting of the belt parts may cause the belt parts to "balloon" and act as brake parachutes. This phenomenon is highly undesirable and particularly when occurring on a fast-moving production line.
  • the belt parts may be permanently creased or wrinkled by the rollers.
  • the most serious problem with ballooning and rearward displacement of the belt parts is that there is a considerable risk that the belt parts are damaged by cutting when individual disposable garments are finally severed from the production web.
  • the belted disposable absorbent articles made according to the invention are easy for a user to handle.
  • the user has no problem in understanding how to use the diaper.
  • the user can readily identify the belt parts that are intended for fastening of the article about a wearer's waist and can without difficulty grip and unfold the belt parts by releasing them from each other and from the surface of the absorbent article in order to prepare the article for use.
  • the belt arrangement will have large unbonded areas that may serve as gripping portions when breaking the transport attachments and unfolding the belt parts.
  • the first and second belt parts may have equal extensions in the cross machine direction, CD. This will produce a disposable garment wherein the ends of the belt parts when brought around the waist of a wearer will come together centrally on the wearer's body. Usually the belt parts are arranged to be fastened together at the front, over the wearer's belly. Alternatively, the first and second belt parts may have different extensions in the CD implying that the belt parts will be fastened together somewhat offset to one side of the wearer's trunk.
  • the belt parts preferably have the same MD extensions, although belt parts of different MD extensions are conceivably within the scope of the invention.
  • the first belt part and/or the second belt part may be folded onto itself, reducing the CD extension of the first belt part and/or the second belt part to equal to or less than the CD extension of the production web.
  • additional releasable attachments may be arranged between the layers of the folded belt part or belt parts.
  • the method according to the invention may involve providing a first and/or a second belt part having an extension in the cross machine direction, CD, greater than the extension of the production web in the cross machine direction, CD.
  • a first and second belt part having an extension in the cross machine direction that is equal to or greater than the extension of the production web in the cross machine direction it may be beneficial to adapt the size of the belt parts to the size of the production web by folding one or both belt parts one or more times.
  • the releasable attachments between the overlapping parts of the first belt part and the second belt part may be spaced apart by 2-100 mm, preferably by 5-80 mm and most preferably by 60-80 mm. However, smaller spacings such as 2-10 mm may be preferred in certain embodiments in particular when the attachments have a small CD-extension.
  • the spacing between the attachments is dependent on the size of the individual attachments as well as on the size of the belt parts. The spacing may be regular with equal distance between the releasable attachments or may be irregular, i. e. with the distance between the releasable attachments varying in the CD.
  • the extension in the CD of the releasable attachments between the overlapping parts of the first belt part and the second belt part may be from 0.1 mm to 70 mm, preferably from 2 mm to 50 mm and most preferably from 5 mm to 30 mm.
  • the releasable attachments may have different CD extensions or may have equal CD extensions.
  • the releasable attachments between the belt parts and the at least one releasable attachment between the second belt part and the production web may have an MD extension of from 0.1 mm to 30 mm and preferably of from 1 mm to 20 mm.

  • the MD extension of the attachments is preferably less than 1/3 of the MD extension of the belt arrangement.
  • the overlapping parts of the first belt part and the second belt part may preferably be joined with at least 4 spaced-apart releasable attachments.
  • the CD spacing between the releasable attachments may be from 60 to 80 mm.

  • the overlapping parts of the second belt part and the production web may be joined with at least 2 spaced-apart releasable attachments and preferably with at least 4 spaced-apart releasable attachments.
  • the overlapping parts of the first belt part and the second belt part may be releasably joined to each other in a separate production step being carried out before releasably joining the second belt part and the production web.

  • thermobonding it is also within the scope of the invention to form at least one releasable attachment by thermobonding.
  • Thermobonding methods include bonding with heated patterned rollers and ultrasonic bonding.
