Claims
- 1. A method for securing a fastening member to an article to be molded, said fastening member being of the type characterized by having a base carrying numerous rows of hook-like projections for mating, releasable engagement with a loose, fibrous patch to form a fastener assembly, said method comprising the steps of:
- (a) applying a thin, protective film to the fastening member to protect and sealingly enclose the hook-like projections around the entire periphery of the fastening member against leakage of molding liquid past the film onto the hook-like projections;
- (b) placing the fastening member in a mold in a position wherein the hook-like projections will be exposed on the surface of the completed molded article and introducing molding liquid to the mold;
- (c) curing the molding liquid to form a solid; and
- (d) removing the protective film from the fastening member after the molding liquid is cured to expose said hook-like projections for mating, releasable engagement with said patch.
- 2. A method according to claim 1 and including the additional step of continuously affixing peripheral edges of said protective film to peripheral edges of the base carrying the hook-like projections.
- 3. A method according to claim 1, wherein the step of removing the protective film comprises applying heat to the mold to cure the molding liquid into a solid and to disintegrate the protective film covering the hook-like projections after the molding liquid has solidified sufficiently to prevent leakage of the molding liquid into the area occupied by the hook-like projections.
- 4. A method for securing a fastening member to an article to be molded, said fastening member being of the type characterized by having a base carrying numerous rows of hook-like projections for mating, releasable engagement with a loose, fibrous patch to form a fastener assembly, said method comprising the steps of:
- (a) applying a thin, protective film to the fastening member to protect and enclose the hook-like projections;
- (b) placing the fastening member in a mold in a position wherein the hook-like projections will be exposed on the surface of the completed molded article and introducing molding liquid to the mold;
- (c) curing the molding liquid to form a solid at a temperature below which the protective film disintegrates;
- (d) applying heat to the protective film subsequent to the molding process causing said film to disintegrate and exposing said hook-like projections for mating, releasable engagement with said patch.
- 5. A method according to claim 4, wherein the step of applying heat to the protective film comprises exposing the film to an open flame for a sufficient period of time to disintegrate said film without damaging said base or said hook-like projections.
- 6. A method according to claim 1 or 4, wherein the step of curing the molding liquid to form a solid comprises the step of cold setting the molded article.
- 7. A method according to claim 1 or 4, wherein said protective film is removed from said fastening member after the fastening member has been removed from the mold.
- 8. A method according to claim 7, wherein the protective film is detached by unsticking the fastening member from the mold.
- 9. A method according to claim 1, wherein the film is detached by cutting or tearing the film away from the fastening member.
