  • Publication number: 20020144924
    Abstract: A package of a continuous strip of material formed from a web comprises a plurality of parallel side by side strip elements separated by dividing lines. The dividing lines are formed such that the width of the strip elements varies along their length with the wider portions of one alongside the narrower portions of the next in a nesting action. The strips are packaged for storage and transport to an end use machine where the strip elements are withdrawn and cut into identical strip portions at spaced positions along the strip so that each strip portion includes a portion of minimum width and a portion of maximum width. The web including all the strip elements is formed into a block in which the web is fan folded back and forth such that each folded portion of the web is folded relative to the next portion about a line transverse to the strip. Each strip element is continuous through the block and is connected by a splice to the beginning of the next strip element.

  • Patent number: 6461464
    Abstract: A colinear laminate honeycomb panel permits the use of two or more different materials to form a single panel. In this manner, a retractable cover for an architectural opening may be formed that has a different appearance depending upon which side of the panel is being viewed. The resultant panel is formed by attaching a plurality of elongated precursor tubular cells, wherein each precursor tubular cell itself comprises at least two strips of material held in proximity to one another by a common carrier strip.

  • Patent number: 6461344
    Abstract: A method of manufacturing an absorbent article in the form of a pants diaper or a sanitary panty starts from a flat blank which includes an elongated absorbent body enclosed between two casing sheets which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the body on the opposite sides thereof. The method includes the step of folding the blank about a transverse axis so that the end edges of the side parts lie edge-to-edge. The front and rear side parts of the blank which oppose one another in the folded state of the blank are joined together by a releasable and refastenable fastener. A pants diaper can be manufactured in accordance with this method.

  • Patent number: 6443938
    Abstract: A method of making a prefolded diaper or other undergarment includes the steps of forming a web of diaper material, placing a fastening system divided between front and back waist sections onto each diaper section of the web and cutting the web to define individual diapers. The diapers are then folded in half at the crotch section and are then microwaved in a high power resonant cavity microwave device to activate the latent elastic portions which are buried within the folded diaper. Where desired, the refastenable fastening system of the diaper, or the front and back waist sections or the diaper, may be registered in a fastening alignment and fastened together when the diaper is folded to create diapers which are useful upon removal from the point of sale container as pull on training pants.

The plastic sheet has a bottom portion which is folded to define a lower edge of the thermoplastic sheet at a fold line. One seals the folded portion of the solid-wall thermoplastic sheet to a lower edge of the mesh sheet. Transverse slits are then formed in the sheets, and the sheets are heat sealed together near edges of the slits to form separate bags between the slits. The slits extend across both lower edges of the bags, but are preferably spaced from the upper edges. One drops produce between the sheet upper edges into the bags, and the bags are then heat sealed adjacent to the upper edges thereof, and subsequently separated by cutting.

    Abstract: A method for producing a pant-type garment in which a first substantially rectangular fabric layer is placed on top of a second substantially rectangular fabric layer. The first substantially rectangular fabric layer is joined to the second substantially rectangular fabric layer, forming a multi-layer fabric. A crescent-shaped cutout section is cutout from the opposed multi-layer fabric edges of the multi-layer fabric, forming opposed tabs at each end of the opposed multi-layer fabric having a first tab and a second tab. The multi-layer fabric is cut transversely in half, forming two multi-layer fabric halves. Each of the multi-layer halves is folded longitudinally and the first tab and the second tab on one side of each of the multi-layer fabric halves is joined to the corresponding first tab and second tab on the opposed side of each respective multi-layer fabric half, forming two outside-in pant-like garments.

  • Patent number: 6083603
    Abstract: An insulation assembly includes an elongated batt of fibrous insulation material having two opposed major surfaces, where the batt has a first facing secured on its first major surface. The first facing extends beyond the side edges of the batt to form opposed flanges suitable for attaching the insulation assembly to a building structure. The batt has a second facing secured on its second major surface, with the second facing extending beyond the side edges of the batt to form opposed flanges suitable for attaching the insulation assembly to a building structure. The method of making an insulation assembly includes moving a pack of fibrous insulation material along a path, where the fibrous insulation material has two opposed major surfaces. A continuous encapsulation material is applied to the pack, and a portion of the encapsulation material is continuously gathered to form a two part fold.

  • Patent number: 6054004
    Abstract: Disclosed is a heat insulating structure in which the surrounding of a heat insulating material such as glass wool is covered with and glued to a casing material such as a poly-film, wherein hotmelts (4,5,6) are applied to the center part or all and an inner portion d and an outer portion e of both ends of a poly-film (3b), and a glass wool (2) is placed on the center to apply a hotmelt (7) to the surface, which is then covered with an aluminum deposition poly-film. In the lower reaches of the conveyer, both ends of the lower poly-film (3b) are folded at the divided line between the inner portion d and the outer portion e to form a three-ply structure, which is pressed to fix, is cooled to normal temperature, and is cured. This heat insulating structure is featured in that improvement in productivity and high adhesive strength can be attained.

  • Patent number: 6042672
    Abstract: In a method of making sealed paper, a web of paper is unrolled and fed, while under a given tension, from a paper roll, and is single-folded or multiple-folded. Prior to the or each folding step, the unrolled web of paper is treated by having an adhesive applied to margin portions thereof destined to be margins of the sealed paper on an inner surface thereof other than along a fold line at which the paper is to be folded. The folded web of paper is then cut to yield a number of sealable paper units so treated and folded as above. The method further includes pressing the sealable paper units to have them sealed with the adhesive applied and thereafter discharging the sealed paper units each of which represents a sealed paper. The method may further include printing a given message or information on a sheet of paper before the paper is rolled into the above mentioned paper roll.

  • Patent number: 6033516
    Abstract: In the production of an anticopy film serving for covering documents against copying, opaque, strip-like coverings are applied by printing to the individual layers of a transparent, multilayer film in a mutually offset arrangement in such a way that the film appears opaque in the plan view, but transparent in an inclined viewing direction. To this end, a film web is printed with the coverings in sections corresponding to the layers, and the sections are subsequently folded over to give the layers.

  • Patent number: 6025053
    Abstract: The process for making a wood board comprises the steps of: a) providing elongated pieces of wood each from a coniferous wood and each having a rectangular cross section; b) detecting an average fiber density of each of the pieces of wood; c) selecting among the pieces of wood those having an average fiber density at least equal to a predetermined fiber density; d) planing off edges of the pieces of wood selected in step c); and e) bonding side by side the pieces of wood planed off in step d) by means of their edges to form the wood board. The board produced thereby shows excellent mechanical characteristics. An advantage of the present invention is to provide a process for making high strength lumber products from coniferous trees which are traditionally considered as nonstructural wood.
