A method for sewing a zipper stringer to fabric, an article, and a slide fastener.

Abstract

A fastener tape (3) and a cloth (101) are sewn to each other along a second virtual line (G2) parallel with a first virtual line (G1) determined from a direct contact between two or more fastener elements (4) and a sewing machine foot (200). The fastener tape (3) and the cloth (101) are sewn to each other along a fourth virtual line (G4) parallel with a third virtual line (G3) determined from a direct contact between a plastic member (10) and the sewing machine foot (200). The plastic member (10) has a guide surface (11) that the sewing machine foot (200) contacts such that the first and third virtual lines (G1, G3) extend on the same line to form one guide line (L1) and the second and fourth virtual lines (G2, G4) extend on the same line to form one planned sawing line (F2).
