ABSTRACT:
Apparatus and method for making bag material from a continuous length of sheet. Side portions of the sheet are turned from opposite sides, and the sheet advanced through a joining station wherein extruded complementary separable fastener profile strips are joined to face of the flange portions which are directed away from the body of the sheet. The sheet carrying the joined fastener strips may then be advanced through a curing station. Subsequently the sheet and fastener strip assembly is conducted through a spreading station wherein the flange portions are spread apart. Downstream from the spreading station the spread sheet may be folded upon itself in a folding station wherein the profiles of the fastener strips may be interengaged, and the folded material may then be wound into a storage roll.
