  • Patent number: 5660657
    Abstract: This invention pertains to methods for use in constructing a garment including a stretched elastic. Specifically, the invention contemplates incorporating stretched elastic into a continuous web, including one or more segments which exert retractive forces in directions counterproductive to the function of either the web, the garment, or both, and nullifying that portion of the stretched elastic which would be counterproductive. The elastics may be cut at appropriate loci. The stretch may be intermittently reduced or eliminated on one or more selected ones of the elastics as the elastics are incorporated into the web. A special coating may be used on the processing rolls to maintain the width dimension of the web at loci disposed after incorporation of elastic stretched across the transverse dimension of the web. Transverse bonds may be formed on the web using a rotary carrying drum, and energy application devices which rotate with the drum, to increase bond forming time.

  • Patent number: 5576090
    Abstract: This invention provides an exceptionally expandable sheet elastic complex which consists of an elastic body sheet and a sheet backing material which is mounted on either one or both sides of it, these two members being bonded together along multiple, oblong, mutually parallel bonding sections, and in which multiple, mutually parallel channels are formed between the two members because the width of the sheet backing material between mutually adjacent bonding sections is greater than that of the elastic body sheet. The sheet backing material does not accept more than the minimum constraint of the elastic body sheet, and its waveform surface has excellent properties as a material for use in sanitary products. The invention also provides a process for manufacturing this sheet elastic complex.

  • Patent number: 5560793
    Abstract: An apparatus and method for stretching a continuously moving elastomeric web in a cross machine direction includes a pair of rotatable, cylindrical rims which are located adjacent the elastomeric web. A supporting mechanism is connected to the cylindrical rims to guide the rims for rotation about their axes. The axes of the cylindrical rims are oriented to position the rims at a close spacing at a first location and a far spacing at a second location. The far spacing is substantially greater than the close spacing relative to the elastic web path. A gripping means is located on the cylindrical rims such that, as the rims are rotated by a driving means, the gripping means receives the elastomeric web and holds the elastomeric web as it is stretched in the cross machine direction. The driving means is connected to the cylindrical rims. In addition, each cylindrical rim may have a center opening therethrough defined by its inner circumferential surface.

  • Patent number: 5545285
    Abstract: The disclosure describes an apparatus and method for applying strips of tensioned elastic material transversely to a moving sheet or web of material, such as a component of a disposal diaper. The heart of the invention is a pair of inclinded, spaced apart transfer wheels located in mirror image relationship across the moving web. The transfer wheels are inclined relative to each other so that the distance between them is greatest at a point on their circumference that lies adjacent the web and least where a point on their circumference is at the greatest distance from the web. A supply drum provides an untensioned elastic strip to the transfer wheels at the point of least distance between them. As the transfer wheels move through 180.degree. of rotation, the elastic is stretched and then released at the plane of the web where it is adhesively bonded to the web. A drive system for the transfer wheels rotates them at a circumferential speed essentially equal to the linear speed of the moving web.

  • Patent number: 5536555
    Abstract: Disclosed herein is a quilted film laminate wherein a film having a plurality of generally parallel slits is laminated to a substrate layer such as a fibrous nonwoven web. Due to processing conditions, once the slit film layer and substrate layer have been laminated to one another, the composite is allowed to retract thereby giving the composite a puckered or quilted appearance with an undulating surface. The undulating surface also causes the slits to form a plurality of openings which are generally perpendicular to the central plane of the film. In addition, due to the undulating nature of the surface of the film, the apertures so created reside in, above and below the central plane of the film layer. The composite so produced has a wide variety of uses not the least of which include a cover material or body side liner for personal care absorbent products. The process for producing the composite is also disclosed.

  • Patent number: 5531850
    Abstract: An apparatus in which material to have elastic applied thereto is carried by a first conveyor in one direction along a flow path. An elastic conveyor extending transversely of the material flow path is operable to continuously draw elastic from storage, tension it and carry it to a feeder head that reciprocates transversely of the flow path. A transverse elastic applicator receives elastic substantially continuously from the feeder head in a square-wave pattern and moves it toward the flow path. The elastic applicator has spaced guide members mounted adjacent opposite sides of the flow path to hold tensioned elastic therebetween extending transversely of the flow path as the elastic applicator moves the elastic to the flow path and applies the elastic to the material on the first conveyor. Cutters positioned inboard of the guide members sever the elastic after it has been applied to the material.
