Zusammenfassung:	A bag machine includes input, drum, and output sections. The drum has at least one seal bar. The sections are mounted to side frames that are single metal plates, not coated after being formed, and/or are comprised of galvanized steel, galvannealed steel, stainless steel or aluminum. The drum has opposing pairs of rotatable zinc plated steel plates. The distance from the seal bars to the drum center responds to the plates rotating. One plate has non-radial (such as curved and/or spiraled) grooves, and the other radial slots, with fixtures having seal bars in the slots and grooves. The winder has a rotatable turret with center and surface wind and center wind only positions. When one collapsible spindle is in the center and surface wind position, another is in the center wind only position. A push off palm mounted in a push off position.
