Abstract: A fastener member 10 has a generally planar base section 12 and a plurality of engaging strips 14 projecting from one surface of the base section 12 and extending parallel to each other in the longitudinal direction. Each of the engaging strips 14 has a vertical portion 16 adjoining the base section 12, and a head portion 18 formed at the end of the vertical portion 16. The head portion 18 of the engaging strip 14 is provided with a plurality of slots 20 extending transversely through the head portions 18. The slots 20 may be inclined with respect to the base section 12. The slots 20 guide headed stems of the opposed fastener member, and reduce the pressure necessary for interengagement. Even when the compressive force is applied in the direction inclined to the base section 12 of the fastener member 10, the interengagement can be easily obtained without bending the headed stems of the opposed fastener member by the guiding effect of the slots 20.

Abstract: The multiple button closure-fastener is a separable strip closure-fastener made from a suitable plastic material comprising a multiple conical male button strip and a multiple conical female button strip. All male and female buttons are coaxial at point of engagement and when pressed together the male buttons snap into the female buttons engaging a like curve causing a pulling together of the male and female surfaces, thus making a mechanical closure with a liquid and hermetic seal. This closure-fastener can also be used in numerous instances where there is no need for a liquid or hermetic seal.

Abstract: A method of continuously producing an elongated strip-like fastener member is disclosed which facilitates highly efficient formation of the fastener member with a great multiplicity of resiliently flexible hook-like projections. The method comprises the formation of an extrusion of plastic material which is shaped between a pair of coacting first and second rollers. Notably, one of the rollers defines a plurality of hook-forming cavities about its periphery within which the hook projections of the fastener member are formed. The forming roller is suitably cooled so as to effect substantial reduction in the temperature of the molten plastic extrusion from which the fastener member is formed. In this manner, the fastener member may be removed or stripped from the forming roller without opening of the hook-forming cavities, thus promoting highly efficient formation of the fastener member without resort to unduly complex equipment of processes.

Abstract: An improved machine for the continuous production of a separable fastening element includes an endlessly-circulating belt of molding modules that, in the preferred embodiment, cyclically pass by at least two injection heads and two removal-wheels once every revolution. Each injection head includes a single-pump-driven reservoir that feeds an injection and forming die operative to first form a backing layer, and then to form plural hook-like projections, by a wedge-like forcing action of a portion of the backing into hook-like mode cavities. The resulting ribbon then cures and includes the hook-like elements standing off of and integral with the backing. The modules include interdigited mold and spacer plates that are each of a generally-rectangular configuration and that together are cooperative to define releasable hook-like forming cavities and a smooth backing-forming two-dimensional surface.

Abstract: A fastener includes a pad element having number of connecting prongs having two locking ridges disposed thereon. The top locking ridges, which are disposed closest to the tip of the prongs, are smaller than the lower locking ridges, thereby facilitating easy alignment of the unisex fasteners of a mating pad. Back prongs on the pad are used for connecting the pad to a surface of an article having holes for receiving the back prongs such that the connecting prongs are positioned to face upwardly from the surface. The fastener is adapted for use in yieldably or separably anchoring a baseball base in place on a playing field ground support attachment having like-constructed fastener prongs whereby injury to a runner sliding into the base will be minimized due to yielding under a relatively low force or separating under a relatively high force of the fastener prongs upon contact thereof.
