Abstract
Abstract An elastic ribbon with fancy designs, especially intended for sewing on the edges of articles of underwear. The ribbon is produced on a straight drop-stitch loom and comprises two adjacent bands of elastic threads and non-elastic threads, one of said knitted bands being flat and uniform and having at least one elastic thread associated with a column of stitches, the other band being constituted by a succession of designs resulting from an association between at least two columns of stitches of nonelastic thread respectively associated with an elastic thread, and is coupled to said flat band by at least one non-elastic thread, in which the elastic thread of the column of stitches in the band of designs adjacent to said flat band has a length practically equal to that of the elastic threads of said flat band and smaller than that of the elastic threads of the other columns of stitches of said band of designs, at least one of the elastic threads of the columns of stitches of said band of designs being transposed here and there from the column of stitches with which it is associated and becoming integrated with one of the other columns of stitches of said band of designs, the transfer of the elastic thread affecting in all cases the column of stitches located on the border of said ribbon.
