A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.

Method and apparatus for making bag using ultrasonic sealing

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.

Method and apparatus for controlling air temperature for making seals

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 down stream 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.

Method of controlling air temperature for making seals

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.

Method and apparatus for making bags

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.

Method and apparatus for sealing a web

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.

A method for forming a stabilized airlaid layer () can include an airforming of a substantially unbonded fibrous layer () which includes absorbent fibers and binder-fibers. The fibrous layer () is exposed to high-frequency electromagnetic energy during a distinctively short activation period to activate the binder-fibers to provide the stabilized, airlaid layer (). In a particular aspect the activation period can be not more than about 3 sec.
