ABSTRACT:
A fastener stringer is disclosed which has a coil-type continuous coupling element of the oval-shaped cross section. The coupling element is stitched onto a support tape which is substantially integrally provided with a levelling cord extending longitudinally of the tape and partly raised from its element-carrying surface. The lower shanks of the scoops formed by the coupling element lie against the levelling cord at their regions adjacent to the bight portions connecting the scoops, so that a notional line extending between the midpoint of the coupling head of each scoop and the midpoint of the corresponding bight portion is oriented substantially parallel to the plane of the support tape.
