    摘要： A method and apparatus for making bags from a film that follows a film path through a bag machine includes an input section located on the film path, a sealing section located on the film path downstream of the input section, an output section located on the film path downstream of the sealing section, and a controller, connected to control the sealing section. The sealing section includes a sealer that includes a heater block and a manifold. There is an air flow path from the heater block to the manifold. Air is heated in the heater block in response to a control signal provided by the controller to the heater block. The heated air is provided through the air path to the manifold. A temperature sensor is disposed in at least one of the air path and the manifold.

    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 method and apparatus for making bags with hem seals is disclosed. The machine includes an infeed section and a draw tape section. Bags are made from a film and a film path extends through the infeed section and through the draw tape section. The draw tape section includes a hem sealer that includes a stationary sealing plate on one side of the film path such that film path passes across the stationary plate. A sealing head is on the second side of the film path, opposite the first side, such that the film following the film path passes between the sealing head and the stationary plate. A sealing section may be included. The draw tape section may include driven infeed an outfeed nips.
