Abstract
A method for manufacturing a slide fastener includes: a sewing step of sewing in a state where first and second element rows are separated from each other; a dyeing step of dyeing in a state where the first and second element rows are engaged with each other and where a first fastener tape and a second fastener tape overlap with each other; and a folding step of folding the first fastener tape and the second fastener tape such that the first fastener tape and the second fastener tape are each buckled in the mountain shape and come into close contact with each other when the first and second element rows are engaged with each other.
Claims6
A method for manufacturing a slide fastener including a pair of first and second fastener tapes, a first element row provided at a widthwise end portion of the first fastener tape, and a second element row provided at a widthwise end portion of the second fastener tape, in which the first and second element rows are capable of engaging with and separating from each other, and when the first and second element rows are engaged with each other, the widthwise end portion of the first fastener tape and the widthwise end portion of the second fastener tape are each buckled in a mountain shape and come into close contact with each other, the method comprising:
- a sewing step of sewing the first element row to the first fastener tape, and sewing the second element row to the second fastener tape in a state where the first and second element rows are separated from each other;
- a dyeing step of dyeing the first and second fastener tapes and the first and second element rows in a state where the first and second element rows are engaged with each other and where the widthwise end portion of the first fastener tape and the widthwise end portion of the second fastener tape overlap with each other in a front-rear direction;
- and
- a folding step of folding the first fastener tape and the second fastener tape such that the widthwise end portion of the first fastener tape and the widthwise end portion of the second fastener tape are each buckled in the mountain shape and come into close contact with each other when the first and second element rows are engaged with each other.
