摘要:
A fastener of the hook and loop type intended to be incorporated into plastic articles by plastic molding processes is formed of a known separable fastener member having a base member and a plurality of engaging elements upstanding from one surface thereof. A covering which intimately surrounds the individual engaging elements protects the elements when exposed to the harsh environment of a molding process. This protecting covering is removable from the fastener after the molding process to expose the engaging elements without substantially destroying the performance thereof.

A strip of fastener material adapted for securing to the surface of a foam bun during molding, carries on a first surface an area of outwardly extending fastening elements constituting one half of a touch fastening system. The first surface is arranged to be positioned so that it faces into a trough in a mold wall and this first surface is provided with a pair of elongated flexible sealing lips adjacent the edges of the are. Magnetizable means are also carried by the strip and the fastener strip has portions extending laterally beyond the sealing lips and beyond the edges of the trough in the mold wall. A strip of removable pressure sensitive tape covers the surface of the fastening elements and extends completely between the lips.

A fastener component is provided with hook-like interlocking elements on the front side of a substrate sheet and an anchor member on the back side. The fastener component is provided with at least one flat portion void of the interlocking elements on the front side to make the fastener component flexible or pliable to fit a curved or bent portion of a molded cushion body or other molded structures on which the fastener component is to be anchored. The fastening element-free flat portions may be provided along the longitudinal side edges of the fastener component for mounting thereon magnetic metal strips which are attracted by magnets embedded in a mold to fix the fastener component in position in the mold during a molding process.

An improvement for a process wherein a strip of fastener material is formed into the surface of urethane foam or the like during molding in a mold. The fastener material includes a backing strip having an outer surface adapted to mate with the foam material during molding and a fastener strip having an outer surface comprising one-half of a fastening system such as hook and loop fastening material. The backing strip and the fastener strip are attached to one another with their respective inner surfaces in face-to-face relationship with their outer surfaces facing outward. The fastener material fits within a longitudinal groove in the mold and the backing material overlaps the groove.

Apparatus for positioning and maintaining a substrate within a tire mold. The substrate receives an applique which is to be transferred to the sidewall of a tire during the curing process. The substrate is of steel construction and is adapted to engage a receiving member within a circumferential surface of the tire mold. The receiving member is magnetized to attract the steel substrate and to retain the substrate and its applique in proper registration with the sidewall of the tire during closure of the mold and the curing process. A lip or pins are provided in association with the retainer to assure proper registration of the applique-bearing substrate with the tire sidewall.
摘要:
A method of forming a panel structure useful in building construction and the like includes the steps of heating a heat expandable plastic in a separable mold having a cavity with the configuration of the resultant panel to form a panel core and adhering thin reinforcing strips to the front and back surfaces of the core. Control over the dimensions and configuration of the panel is obtained by adhering the strips to the core in the mold while applying heat thereto whereby core shrinkage is minimized. The strips may be adhered to the core during initial heating of the plastic material to form the core or may be adhered to the core in the mold subsequent to core formation.
