摘要： A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

摘要： A machine for making bags is disclosed and includes input, drum, and output sections. The drum section has at least one seal bar on a drum. The sections are mounted to side frames that are single metal plates. The frames are not coated after being formed and/or are comprised of at least one of galvanized steel, galvannealed steel, stainless steel or aluminum. The drum is comprised of first and second plates, and opposing third and fourth plates. The first plate is rotatable with respect to the second plate, and the third plate is rotatable with respect to the fourth plate. The distance from the seal bars to the center of the drum is responsive to the rotation of the plates. The first plate has a plurality of non-radial grooves, and the second plate has a plurality of radial slots, with fixtures in the slots and grooves. The fixtures are connected to seal bars. The non-radial grooves are curved and/or spiraled. The plates are comprised of zinc plated steel and/or are discs. The winder includes a rotatable turret with a center and surface wind position, and a center wind only position. When one spindle is in the center and surface wind position, the other spindle is in the center wind only position. A push off palm mounted in a push off position. The spindle is collapsible.

摘要： A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a sealing zone, and a weakening zone disposed within the single sealing zone. The single sealing zone may be a heated perforator, and may include a heating wire. The heating wire may be an NiCr wire stitched into holes in a cap or on the seal bar. Bushings may be disposed in the holes.
