  • Patent number: 10549874
    Abstract: A pouch machine includes an infeed section, a sealing section, and an outfeed section. The infeed section provides a pouch or laminate to the sealing section, and the outfeed section receives the sealed pouch from the infeed section. The sealing section includes at least one sealer that has a sealing fixture disposed to move in a first direction toward and away from a sealing position. A linear actuator is mounted to provide a controlled motion in a second direction, that is not the first direction. A linkage is connected between the linear actuator and the sealing fixture. The linkage translates the controlled motion of the actuator into controlled motion of the sealer. The linkage preferably multiplies force when the sealer is in the sealing position, and multiplies distance/velocity when the sealer is retracted. The sealing fixture preferably includes a die backing member and a sealing die. The die backing member has at least one clip mounted on it.

  • Publication number: 20190210344
    Abstract: A method and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate.

  • Patent number: 8439812
    Abstract: A machine is disclosed for securing a closure system onto a discrete pouch. The machine includes first, second and third stations. The first station is capable of advancing discrete pouches and lifting and folding a portion of a first major surface of each pouch upon itself to form a lip, and exposing an inner surface of a second major surface. The second station is capable of positioning and attaching a closure system transversely across the exposed inner surface. The closure system includes a track having first and second legs each having an outer surface. The first and second legs are joined together by an opening/closing mechanism which includes a movable member capable of being moved back and forth. The third station is located downstream from the second station and is capable of unfolding the lip and securing opposite ends of the lip to the outer surface of the second leg.

  • Patent number: 8257235
    Abstract: An in-line method is disclosed for securing a closure system onto a discrete pouch. The method includes advancing a discrete pouch through a first station in a machine direction with the closed bottom of the pouch being the leading edge and a first major surface of the pouch faces upward. The first major surface is folded upon itself to form a lip having an exposed first surface while a second major surface of the pouch has an exposed inner surface. The method also includes routing the pouch to a second station where a closure system is transversely attached across the exposed inner surface. The closure system includes an opening/closing mechanism. The method further includes routing the pouch to a third station where the lip is unfolded and opposite ends of the lip are secured to the outer surface of the closure system.
