Claims
- 1. A fastener member for molding of plastic material, the fastener member comprising:
- a fastener tape including a substrate, said fastener tape comprising engaging elements configured to engage upholstery provided on a top side of the substrate, said fastener tape further including ridges extending continuously in a longitudinal direction on both edges of a back side of the substrate, said back side of the substrate including anchoring elements configured to engage plastic material;
- wherein the ridges project outwardly such that an outermost part of the ridges is about 0.3 to 5 mm from an outer edge of the substrate.
- 2. The fastener member for molding as defined in claim 1, wherein said engaging elements have a shape of at least one of a mushroom, hook or arrowhead.
- 3. The fastener member for molding as defined in claim 1, wherein said engaging elements are configured to engage with looped fibers of upholstery material.
- 4. A fastener member molding apparatus comprising:
- a fastener tape including a substrate, said fastener tape comprising engaging elements on a top side of the substrate configured to engage upholstery and ridges extending continuously in a longitudinal direction on both edges of a back side of the substrate; and
- a mold having a recess with an open side facing an interior of said mold;
- wherein a difference between a width of outermost parts of the ridges and a width of said recess in said mold in which the fastener tape is fitted is in a range of -1 to 5 mm, and a difference between a length of said fastener tape and a length of said recess in said mold is in the range of -5 to 5 mm.
- 5. The fastener member for molding as defined in claim 4, wherein said engaging elements are configured to engage with looped fibers of upholstery material.
- 6. The fastener member for molding as defined in claim 4, wherein said engaging elements have a shape of at least one of a mushroom, hook or arrowhead.
- 7. The fastener member for molding as defined in claim 4, wherein said recess is in the form of a channel, wherein said outermost parts of said recess include opposed faces connected by a bottom surface of said recess.
- 8. The fastener member for molding as defined in claim 4, wherein said recess is in the form of a channel, wherein said outermost parts of said recess include opposed walls extending from a bottom surface of said mold towards said interior of said mold, said opposed walls connected by a bottom surface of said recess.
- 9. A fastener member for molding of plastic material, the fastener member comprising:
- a fastener tape including a substrate, said fastener tape comprising engaging elements extending from a top side surface of the substrate for attachment of the fastener tape to loop fibers of an upholstery material, and sealing ridges extending continuously in a longitudinal direction on both edges of a back side surface of the substrate which is opposite to the top side surface of the substrate;
- wherein the ridges project outwardly from the back side surface of the substrate in a direction away from a center of said substrate, such that an obtuse angle which faces the center of the substrate is defined between the back side surface of the substrate and each of said sealing ridges and an outermost part of the sealing ridges is about 0.3 to 5 mm from an outer edge of the substrate.
- 10. The fastener member for molding as defined in claim 9, wherein said engaging elements have a shape of at least one of a mushroom, hook or arrowhead.
- 11. A fastener member to be embedded in a molded article by molding, the fastener member comprising:
- a fastener tape including a substrate, said fastener tape comprising engaging elements extending from a top side surface of the substrate for attachment of the fastener tape to loop fibers of an upholstery material, and sealing ridges extending continuously in a longitudinal direction on both edges of a back side surface of the substrate which is opposite the top side surface of the substrate, said sealing ridges extending from the back side surface of said substrate in a direction away from a center of said substrate, such that an obtuse angle which faces the center of the substrate is defined between the back side surface of said substrate and each of said sealing ridges;
- wherein a difference between a width of outermost parts of the ridges and a width of a recess in a mold in which the fastener tape is fitted is in a range of -1 to 5 mm, and a difference between a length of the fastener tape and a length of the recess in the mold is in the range of -5 to 5 mm, said sealing ridges extending in a direction toward a wall of the recess so as to substantially seal a gap between the sealing ridges and the wall of the recess.
- 12. The fastener member for molding as defined in claim 11, wherein said engaging elements have a shape of at least one of a mushroom, hook or arrowhead.
- 13. The fastener member for molding as defined in claim 11, wherein said recess is in the form of a channel, wherein said outermost parts of said recess include opposed faces connected by a bottom surface of said recess.
- 14. The fastener member for molding as defined in claim 11, wherein said recess is in the form of a channel, wherein said outermost parts of said recess include opposed walls extending from a bottom surface of said mold towards said interior of said mold, said opposed walls connected by a bottom surface of said recess.
