Abstract
An element row for a slide fastener made by stamping a monofilament made of synthetic resin. Element coupling heads have a shape which enables the elements to be reliably coupled with each other even though the gaps between upper and lower leg portions of the elements are small. Each coupling head has flat sectional portions extending from center portions of one of the ends of the upper and lower leg portions toward each other, and the flat sectional portions have increasing widths. A coupling portion of the element head is sandwiched between both the flat sectional portions, is thinner than the flat sectional portions, and has tip end portions projecting toward opposite sides in the longitudinal direction of the element row. The coupling portion is reliably engaged in a small gap formed between the coupling heads and the upper and lower leg portions of adjacent elements of a mating element row. An apparatus and method for making the element row is also disclosed.
