Abstract
Abstract A slide fastener stringer having a series of discrete fastener elements arranged along one of the longitudinal edges of a stringer tape made of a warp-knitted fabirc. At least one element connector adapted to carry the fastener elements at preassigned spacings is received in one of the interwale grooves at least one surface of the stringer tape along the longitudinal edge portion thereof and is buried therein lower than the outer surfaces of the adjacent wales by way of protection against wear or damage.
