Abstract: A web packaging machine for enclosing a food product within a food product package has a first sealing station that seals an upper web of packaging material to a lower web of packaging material to thereby partially enclose the food product in the food product package and a second sealing station configured to further seal the upper web of packaging material to the lower web of packaging material to thereby fully enclose the food product in the food product package. A lower web transport conveyor conveys the lower web of packaging material from upstream to downstream first through the first sealing station and then through the second sealing station.

Abstract: A bladder device is for moving a component of a web packaging machine that forms and encloses a food product in a food product package made of webs of packaging material. The bladder device has a bladder and a nipple stub coupled to the bladder and having a first end configured to receive a gas and a second end configured to dispense the gas into the bladder to thereby inflate the bladder and move the component of the web packaging machine. A collar coupled to the nipple stub such that the bladder is sandwiched between the collar and the second end of the nipple stub. The second end of the nipple stub has a depression and the collar has a boss that is oriented towards the depression such that tightening the collar on the nipple stub forces the bladder into the depression and thereby forms a fluid tight seal.

Abstract: A cutting station is provided for separating a plurality of packages from a continuous chain of sealed packages formed on an indexing motion packaging machine. The cutting station includes a plurality of cutting blades configured in a nested arrangement to form closed curved contours for producing curved cuts in the continuous chain of sealed packages to form severed individual sealed packages having contours corresponding to the contours of the blades with a minimum of waste of the severed joined webs. A blade receiving plate is provided for receiving the severed sealed packages, and is mounted for movement relative to the cutting blades and formed with a plurality of recesses configured in a nesting arrangement of closed curved contours aligned with and corresponding in shape to the closed curved contours of the cutting blades.

Abstract: A forming station comprises first and second forming die members. A closing station comprises first and second closing die members. A lift operatively couples at least three of the members together such that operation of the lift moves the three members together. The closing station is located downstream of the loading station and is for closing a pocket in a first web of packaging material with a second web of packaging material. The second web of packaging material is oriented in the closing station so as to engage with the first web of packaging material and fold a foldable flap downwardly with respect to a conveyor as the conveyor moves from upstream to downstream.
