    Abstract: The present invention provides a method for forming preferably a unitary polymeric hook fastener(20) comprising a flexible backing(22), and a multiplicity of spaced hook elements(9) projecting from the upper surface of the unitary backing(22). The hook elements(9) each comprise a stem portion(24) attached at one end to the backing(22), and a head portion(21) at the end of the stem portion(24) opposite the backing(22). The head portion(21) projects in different directions for some adjacent hook members(9) which adjacent hook members(9) each have a flat face(35,36) which flat faces(35,36) are mutually opposing in face to face relation.

    Abstract: A unitary fastener of a thermoplastic resin comprising a base film layer having generally parallel upper and lower major surfaces, arranged in a first direction the base film layer being oriented at least in the first direction. The backing layer having on at least one surface separated surface elements extending at an angle to said first direction. The invention is also related to a method of forming a unitary fastener. The method includes the steps of extruding a thermoplastic resin in a machine direction through a die plate having a continuous base portion cavity and one or more rib cavities extending from the base portion cavity, forming a strip having a base layer and continuous rib. This scoring or cutting the ribs and at least a surface layer of the film structure forms predetermined separable elements. This inelastically stretching the strip to separated projections and the separated separable surface elements across the strip. The spacings between adjacent separated separable surface elements comprises an oriented film.

    Abstract: The present invention concerns an extrusion formed reticulated web, mesh or netting including reticulated hook fasteners for use with hook and loop fasteners the polymer netting comprising two sets of strands at angles to each other. The first set of strands are a plurality of oriented (molecular orientation created by stretching) strands extending in a first direction and are generally mutually parallel and linear. The second set of strands are a plurality of substantially parallel strands attached only to a first face of the first set of oriented strands. The first set of oriented strands occupy a first planar cross-sectional area in the thickness direction of the formed netting. Said second set of oriented strands occupy a second planar cross-sectional area in the thickness direction of the formed netting. Preferably, these first and second planar cross-sectional areas are substantially mutually exclusive and are abutting. The polymer netting is preferably made by extruding a thermoplastic resin through a die plate, which die plate is shaped to form a base film layer and spaced ridges or ribs projecting from a surface of the base layer. The spaced ridges or ribs formed by the die form the first set of strands forming the reticulated mesh or netting. The second set of transverse strands are formed by transversely cutting the base layer at spaced locations along a length, at a transverse angle to the ridges or ribs, to form discrete cut portions. Subsequently longitudinal stretching of the ridges (in the direction of the ridges or the machine direction) separates these cut portions of the backing, which cut portion then form the second set of spaced apart strands of the reticulated mesh or netting.

    Abstract: A fastener component comprises a field of loop-engaging elements (10) each secured to a support (14). At least one of the elements (10) has a molded, cantilever stem (16) secured to the support at a base (12), projecting from the base at an acute angle ( alpha ) to the support (14) substantially linearly along a lengthwise axis to the region of a distal tip (20). The length of the projection upon the support (14) of the portion of the cantilever stem (16) beyond the base (12) is between about 0.5 and 2.0 times the width of the base of the element, and the length of the projection upon the support (14) of the portion of the stem (16) between the tip (20) and the point of its greatest spacing from the support (14) is less than about 0.25 times the width of the base (12). The structure of the element can be useful for engaging very fine fibers that have low loft such as are found in inexpensive non-woven materials, due to minuscule motions of the head of the fastener element during engagement. Molds and methods for forming such fastener components are also disclosed.
