    摘要： Forming a fastener component having heads constructed to engage loops formed e.g. of fibers of a mating component, comprises forming, from a thermoformable material, a preform product having a sheet-form base and an array of preform stems integrally molded with and extending from the base to corresponding terminal ends, by a process having a machine direction and a cross-machine direction. Each molded stem has at least two terminal features spaced from one another in the cross-machine direction, the features having a transverse shape about which engaging fibers can bend, the features having a thickness of about 0.25 mm (0.010 inch) or less, preferably about 0.20 mm (0.008 inch), and for personal care products and the like preferably about 0.1 mm (0.004 inch) or less. The terminal ends of the features are heated to a predetermined softening temperature and the terminal ends are contacted to reform the terminal ends to form heads therefrom that overhang the sheet-form base sufficiently to engage loops.Also shown are molded stems that have at least two terminal features spaced from one another in the machine direction; molded preform having substantially parallel side surfaces on all sides, e.g., of “M” or crossed “M” profile of substantially thin fin or crossed thin fin form of molded stems that carry upwardly directed, spaced apart prongs.Preforms are shown having at least three prongs along at least one coordinate. Each prong of a group of at least two neighboring prongs is coalesced to form a head or all prongs of a stem are coalesced to form a single head.

    摘要： Fastenings, including stretchy or flexible “zebra-like” and “leopard-like” appearing materials, are disclosed having spaced bands or a distribution islands of molded loop-engageable hooks or molded pre-forms for hooks, between which are bands or regions of different character. Molding is by rigid molds filled from the base region of the stems. In embodiments, linear bands or islands of fastener elements are themselves inextensible in the direction of their extent and comprise multiple rows of fastener elements. For ease of forming a uniform, elastically stretchy or flexible product, the bands or islands of fastener elements extend in the machine direction during manufacture. Embodiments shown employ a widthwise continuous carrier of uniform character to which multiple spaced bands or islands of hooks have their molded stems in situ bonded, and in other embodiments, over-lapping margins of the bases of hook bands are in situ laminated to surface structure of adjacent bands of carrier using a laminating nip in which one of the rolls is a mold roll. For a preferred mode of manufacture of an elastically stretchy product, stretchy carrier material is stretchy only in the widthwise (cross-machine) direction. In composite hook and loop fastener products, the bands or regions of material between adjacent bands or islands of hooks comprise loop-engageable material, that is uniform in construction widthwise, the loop-forming material itself being an elastically stretchable or a flexible component. In useful product categories, the hook bands or islands and intervening regions of material have importantly different width ranges. Novel elastically stretchable and flexible loop-defining materials, and their methods of manufacture are shown. In situ lamination of hook, bands or islands on surfaces of materials held in a planar orientation or presenting a planar surface are also shown, flexible materials on tenter frames and rigid materials.

    摘要： A method of forming a mold having cavities for molding loop-engageable, hook-shaped fastener elements, includes: supporting a first plate having an outer surface that defines a plane; manipulating a material-cutting beam of a laser along a predetermined curved profile to cut a cavity into the outer surface of the first plate, the predetermined curved profile being generally hook-shaped, the cavity defined by a wall extending into the first plate from the outer surface; in a series of subsequent actions, repeatedly indexing the first plate relative to the laser to direct the material-cutting beam at further positions on the first plate and repeating the step of manipulating the material-cutting beam of the laser relative to the first plate to form a series of cavities, each having a hook-shaped profile; and positioning a second plate adjacent the outer surface of the first plate, the second plate providing a side wall surface for each of the cavities of the first plate, the first plate and the second plate in combination forming a mold having cavities for molding loop-engageable, hook-shaped fastener elements. Various methods for aligning such mold plates in a fastener element molding apparatus are also provided. A hook product includes a stem portion integrally molded with and extending from a sheet-form base to a distal end, the stem portion having a planar side; and a crook portion extending from the distal end of the stem portion to overhang the sheet-form base in an overhang direction, the crook portion having a flat planar side co-planar with the planar side of the stem, and an upper surface extending upward from an upper extent of the planar side of the crook portion to an apex.

    摘要： Abstract of the Disclosure Improvements are disclosed for an apparatus for continuously molding small fastener elements integral with a base web from a flowable resin. The apparatus comprises a cylindrical mold roll rotatable about an axis and defining small fastener element-shaped mold cavities in the surface thereof, and pressure-applying means to apply operating pressure to force the resin into the cavities at a pressure zone. The pressure-applying means and mold roll define a mold gap therebetween for forming the base web. The advantageous use of relatively long mold rolls, to produce a correspondingly wide web, and the use of higher molding pressures, e.g. to form very small fastener elements, is enabled by various improvements, including means to maintain the mold gap at a desired thickness profile across the length of the molding region of the mold roll under operating pressure. In some cases the pressure-applying means includes a pressure roll, in other cases it includes a resin nozzle assembly or pressure head. In some other cases it includes a belt. Various control schemes are also disclosed, as are means to provide cooling. In some particularly useful embodiments, at least one of the rolls of the apparatus has a resiliently deformable surface. Methods of molding fastener elements directly on a sheet material, such as sandpaper, are also disclosed, as well as methods for laminating.
