Abstract
A tape-mounted fastener comprising a male tape and a female tape in which the male tape is made of a cloth tape (18) onto which several resin male parts (6) are molded and fastened at certain intervals and a female tape is made of a cloth tape (30) onto which several resin female parts (6) are molded and fastened at the same intervals as said male parts with no mounting holes pierced on either of said cloth tapes. The engagement protrusions (20) of the male parts (6) stand upright directly from the cloth tape (30) without the aid of a base. The male and female parts preferably have a ring-shaped appearance when viewed from either the front or the back.
Claims10
A tape-mounted fastener comprising:
- a male tape made of a cloth tape on which several resin male parts are molded and fastened at certain intervals with no mounting holes pierced on said male cloth tape, said male parts each having an engagement protrusion, said male parts each having an exposed cloth at its center when viewed from either front or back;
- and
- a female tape made of a cloth tape on which several resin female parts are molded and fastened at the same intervals as said male parts with no mounting holes pierced on said female cloth tape, said female parts each having an exposed cloth at its center when viewed from either front or back.
A method for manufacturing a tape-mounted fastener comprising a male tape and a female tape in which the male tape is made of a cloth tape on which several resin male parts are molded and fastened at certain intervals with no mounting holes pierced on said cloth tape, said male parts each having an exposed cloth at its center when viewed from either front or back and the female tape is made of a cloth tape on which several resin female parts are molded and fastened at the same intervals as said male parts with no mounting holes pierced on either of said cloth tapes,
- said method comprising the steps of:
- providing a cloth tape having a coarse texture that allows permeation of molten resin under a molding pressure between upper and lower dies forming a space for molding the fastener;
- sandwiching and fastening the cloth tape at dents positioned inside engagement protrusions of the male parts directly by said upper and lower dies;
- and
- injecting synthetic resin into the space for molding so that the front side and the back side of the male parts formed on either side of the cloth tape are integrated by the synthetic resin permeating through the cloth tape.
