The operation required to sew the Joining & Taping Seam (performed on styles 36200UX52 and 36200UX60) is similar to that of the Butt Seam, except that instead of a top coverstitch covering the top of the material, there is a folded tape that is sewn down with a 4–needle 5–thread bottom coverstitch type 408 over the butted seam.  The final result is a 408LSz-1 (modified) stitch and seam type, Figure 11.

This type of operation was designed mainly for men’s, women’s and children’s briefs, but could also be used for any type of operation where a tape needs to be attached and sewn.
