Abstract

Fastener tape and fabric are sewn along a second imaginary line that is parallel to a first imaginary line established by direct contact between two or more fastener elements and a presser foot. The fastener tape and the fabric are sewn along a fourth imaginary line that is parallel to a third imaginary line established by direct contact between a plastic member and a presser foot. The plastic member has a guiding surface with which the presser foot comes into contact such that the first and third imaginary lines extend collinearly so as to form one guiding line and the second and fourth imaginary lines extend collinearly so as to form one projected sewing line.

Claims16

Dependent claims

A method of sewing a fastener stringer to a fabric by using a sewing machine provided with a presser foot, the fastener stringer including a plurality of fastener elements secured, individually or as a continuous piece, to an elongated side edge portion of a fastener tape in an elongation direction of the fastener tape and a plastic member located adjacent to a fastener element positioned at a terminal end among the plurality of fastener elements in the elongation direction of the fastener tape so as to prevent a slider from falling, the method comprising:

linearly feeding a fastener stringer based on direct contact between the presser foot and two or more fastener elements included in the plurality of fastener elements and positioned adjacent to the presser foot, a first imaginary line established by the direct contact between the presser foot and the two or more fastener elements;
sewing the fastener tape to the fabric along a second imaginary line that is parallel to the first imaginary line;
linearly feeding the fastener stringer based on direct contact between the plastic member and the presser foot, a third imaginary line established by the direct contact between the plastic member and the presser foot;
and
sewing the fastener tape to the fabric along a fourth imaginary line that is parallel to the third imaginary line, wherein
said linearly feeding a fastener stringer based on direct contact between the presser foot and two or more fastener elements and said linearly feeding the fastener stringer based on direct contact between the plastic member and the presser foot are performed in this order or in a reverse order, and
the plastic member has a guiding surface with which the presser foot comes into contact such that the first and third imaginary lines extend collinearly so as to form one guiding line and the second and fourth imaginary lines extend collinearly so as to form one projected sewing line.

4 more elements

A slide fastener comprising:

first and second fastener stringers;
and
a slider that moves in front-rear direction so as to couple or decouple the first and second fastener stringers, wherein
the first fastener stringer comprises a first fastener tape, a plurality of first fastener elements secured, individually or as a continuous piece, to an elongated side edge portion of the first fastener tape extending in the front-rear direction, and a plastic member located adjacent to a first fastener element positioned at a terminal end among the plurality of first fastener elements in the front-rear direction so as to prevent the slider from falling,
respective first fastener element included in the plurality of first fastener element includes a surface that faces inward of the first fastener tape and is included in a first imaginary line extending in the front-rear direction,
the plastic member is a box member of a separable stop member, the box member including a box bar being positioned adjacent to the fastener element at the terminal end and inserted into the slider and a box body having one or more stopping surfaces to which the box bar is coupled and by which the slider is prevented from moving;
and
the box member has a guiding surface arranged collinear to the first imaginary line.
