ABSTRACT:
A slide fastener stringer comprises a support tape having a foundation fabric strip either woven or knitted which is coated on both sides with a coat of elastomeric or rubberry material and a row of coupling elements mounted on an inner longitudinal edge of the tape. The coat is reduced in thickness along the inner edges of the tape to alleviate the tension of sewn seams thereat which secure the coupling elements to the tape.
