<p>A continuous coupling element consists of an elongated filament of a synthetic resin or the like which is formed into a multiplicity of undulations forming a row of a plurality of first loops. A series of coupling heads are formed by said first loops along one longitudinal side of the row. The filament also forms a plurality of second loops arranged along another longitudinal side of the row. Each first loop is formed by a pair of shanks which are each disposed generally in a plane perpendicular to the elongation of the row. The general configuration of the first and second loops is such that they are held in contacting relationship at three types of discrete points for increased positional stability. The continuous coupling element can be fastened to the stringer tape by two rows of stitching, one passing over the shanks of the first loops and the other over the second loops.</p> |
