Definitions

  • a manufacturing method for articles essentially consisting of a hoop or for pre-forms for such articles
  • the present invention is a process for the manufacture of articles comprising or consisting of hoops, which are intended to be worn by a wearer, such as a human wearer, such as a head-band or a belt.
  • the invention relates to the manufacturing of such articles.
  • the present invention further relates to pre-forms for making such hoops.
  • US 6681406 (Timberland) relates to the making of garment belts including an extendible insert, which may flex or stretch, while the belt is being worn so that the belt adapts to variations in the wearer's waist size and shape.
  • US 4134154 describes the making of a belt preferably of a polyethylene material, where the cutting edge as well as side walls and holes are fused by the application of heat thereto to avoid the unraveling of the thermoplastic material. The longitudinal closing is performed by sewing.
  • none of the disclosed processes allows the manufacturing of belts at very high production speeds, in particular, if these belts are composed of several materials or pieces. In the present context, very high production speeds relates to the manufacturing of more than about 500 items per minute.
  • Such mass production is typically based on web materials such as but not limited to the ones described in the above mentioned US4134154, namely synthetic materials, although conventional belt materials such as leather or woven materials may be used.
  • a particular application of a belt or a hoop structure is in articles or garments, which are worn on the wearer, mostly though not exclusively on a human wearer. Therein, hoops may encircle the waist of a wearer, such as conventional belts do. They may also encircle the head, legs or other extremities of a wearer, such as headbands or sock suspender do. Other articles may include both a waist hoop and leg hoops, as pants may do.
  • PCT application PCT/EP2008/003844 published as WO08/141756, - hereinafter referred to as the PCT'3844 application - describes the manufacturing of articles such as pants or pants-like structures, which comprise left and right leg hoops which are folded over along a fold line and which encircle the legs of a wearer during use, and to the manufacturing of such articles.
  • the leg hoops are manufactured by flipping front and rear parts of the hoop material, thereby creating the hoop structure which is essentially with one and the same surface in contact with the skin of the wearer, and a 3D cup shape, to be placed in the crotch area of the wearer when the product is in use.
  • the body conforming 3D or cup shape of the article is further supported if the leg hoop is folded upwardly (i.e. the lateral edges in the cup region are oriented towards the crotch crease of the wearer during use). Whilst this method as described in the PCT'3844 application is very suitable for forming pants or pants-like structures, it does not related to other articles. Henceforth, it is an object of the present invention, to provide an alternative method so as to arrive at alternative articles or pre-forms. Summary
  • the present invention is a manufacturing method for being carried out on a manufacturing equipment for the manufacture of a pre-form for or an article comprising or essentially consisting of a hoop.
  • the equipment comprising the elements of a closed loop operating means defining a machine direction (closed loop operating means-MD), a machine centre line aligned with that machine direction, and a cross-direction and a surface oriented essentially parallel to a MD/CD plane.
  • the equipment further comprises rotating equipment attached or otherwise operatively associated to the closed loop operating means comprising support plates, each rotatably mounted around a rotating axis which is essentially parallel or perpendicular to the surface of the closed loop operating means.
  • the method comprises the steps of (a) providing a first web material for forming the hoop extending along the machine direction of the closed loop operating means;
  • Fig. 1 shows a schematic view of a hoop structure
  • Fig. 2 shows a schematic view of the process steps for making a hoop or a pre-form therefore
  • Fig. 3 shows a schematic view of a loincloth article
  • Fig. 4 shows schematically the steps for the manufacturing of a hoop from a single hoop web material
  • Fig. 5 shows an alternative process for making a hoop or a pre-form therefore;
  • Fig. 6 shows a particular feature for this process.
  • the present invention relates to a method of manufacturing of a pre-form which suitably can be included in the manufacturing of a variety of articles comprising or essentially consisting of a hoop.
  • Such articles are typically worn by a wearer, such as a human wearer.
  • Such articles may be garments or apparel, which may be worn directly on the skin of the wearer, or which may be worn over other articles.
  • Such articles may cover a smaller or larger part of the body of the wearer, and may cover one part such as the waist or a leg only, or may cover several parts, such as legs as well as waist regions.
  • such articles may be suspender belts, head bands, armbands, tube tops, or other belt or band-like structures comprising hoops.
  • Such articles may also comprise further materials in addition to one or more hoops, such as in caps, loincloth articles or diapers, pants or pants-like structures.
  • Such articles may be disposable, such as when being used as disposable underwear, or for operation theatre clothing.
  • a particular application relates to pants or pants- like structures to be worn on the lower torso of a wearer, which comprise leg hoops, i.e. elements encircling the legs of a wearer during use, such as diapers, training pants, adult incontinence articles or other absorbent or non absorbent articles, which exhibit a particular good body-conforming fit.
  • leg hoops i.e. elements encircling the legs of a wearer during use
  • diapers, training pants, adult incontinence articles or other absorbent or non absorbent articles which exhibit a particular good body-conforming fit.
  • the term "hoop” refers to a circular strip of flexible material in particular in the context of or as a garment or apparel. Referring to Fig.
  • such a hoop 1001 forms a closed circular structure, which may, for example, be worn around the waist of a wearer (not shown).
  • the hoop may have a hoop width dimension 1025 and a hoop thickness 1024. Perpendicularly thereto, the circumferential length (corresponding to the waist circumference of the wearer) may be measured along the length direction 1021 of the hoop.

  • These connecting lines 1030 may be arranged so as to be positioned in the side regions of the wearer, such that one part of the hoop may be considered a front part 1012, and the complementing part the rear part 1018.
  • the front and/or rear part may further be unitary, or may be made of separate pieces of material attached to each other to form the front or rear part.
  • the hoop may be of a single layer or may be a composite material.
  • the hoop materials may be a single or any combination as generally suitable for being worn as a garment or apparel, which typically can be described by exhibiting a certain strength, conformability, flexibility, suppleness, skin compatibility etc.
  • the hoop material may be extensible (i.e. showing at least to a certain extension a relatively low resistance irrespective of retracting forces) or elastic (i.e. exhibiting at least within certain extensions certain retractive forces).
  • the hoop forming material may be arranged in a hoop pre-form. Within the present context, this refers to the arrangement of the hoop material such that a closed hoop may readily be formed.

  • the rotating equipment 5308 comprises four rotatably mounted support plates 5310, each one positioned forwardly and rearwardly left and right (relative to the manufacturing direction 1304).
  • each support plate 5310 is essentially shaped like an elongated trapeze, with a rectangular first section 5312, and a triangular second section 5313. This triangle is delimited by MD- and CD- lines as well as tapering line 5160, here shown at a 45° orientation.
  • the rotating axis 5320 is positioned at the connecting line of the first and second sections, either inwardly of the trapeze (for outward rotation of the first section of the support plates), or outwardly of the trapeze (for inward rotation of the first section of the support plates as in Fig. 5A to 5D).

  • Fig 2C it can be seen, that after the rotation step, the first portions of the support plates have been rotated inwardly towards the centreline of the closed loop operating means. As the front 1212 and the rear 1218 portions of the hoop material remain affixed to the support plates, these will also turn inwardly, with their first upwardly oriented surfaces 1370 remaining upwardly oriented.

Through this, an overlap between the front left and right and rear left and right portions of material 1210 is achieved.
