ABSTRACT:
A conventional fin-type seam formed on tubed bag forming sheet material provided on one face with heat sealable material, has heat sealed overlapping edge portions forming the seam. The fin slides over a back-up plate extending between it and the body of the tube to prevent scuffing of the heat sealable material with consequent seal failure. A tracking wheel engaging the fin presses it against the back-up plate, and maintains alignment.
