摘要:
Methods and apparatus for changing a strip of sealed bag precursors in to open bags are disclosed. The apparatus is referred to as a transforming or bag opening machine and includes a separation station and may include a perforation station and a piercing station. The perforation station forms a plurality of end perforations in the multiple layers of a strip of sealed bag precursors. The separation station separates the plurality of end perforations in at least one film layer of the trip to form a plurality of bag openings. The plurality of end perforation are torn by the separation station, which includes manipulating the rotation of a main roller, a pressure roller and at least one separation roller.

A package and a method and apparatus for producing same are set forth. The package preferably is made of two single-faced corrugated sheets having cohesive corrugated surfaces. A lower sheet has side walls bent upwardly at edge portions thereof and flanges bent outwardly from the upper edges of the walls. An upper sheet bridges an object to be packaged located on the main portion of the lower sheet between the side walls, and has edge portions adhered to the flanges of the lower sheet. The ends of the two sheets are pressed to cause them to adhere together with the side walls simultaneously being folded outwardly at the centers and adhered to themselves. In the machine and method for producing the package, a first web has side walls bent upwardly and flanges outwardly by suitable folding rails as the web is moved longitudinally in a horizontal direction. After the object is added, a second web is brought downwardly near the first web with the side edges of the second web and the flanges of the lower web pressed together. The trailing end of one package and the leading end of another package are then pressed together and severed along a central line to complete the operation.

Transforming machines for changing a strip of unopened bag precursors into open bag precursors are disclosed that include a drive motor, a separation station, a sensor electrically connected to a controller that is electrically connected to components of the separation station. The separation station includes a first roller, a separation roller driven by the drive motor, and a pressure device having an actuator selectively activating the pressure device to apply pressure to the strip of unopened bag precursors passing over the first roller. In operation, the controller, based on a signal from the sensor, determines when perforations are located in a gap between the pressure device and the separation roller and at that time signals the actuator to activate the pressure device, with the drive motor driving the separation roller, thereby separating the perforations in a first film layer, but not the perforations in a second film layer.

Inflatable packaging with self-sealing air bubbles includes a bubble layer, a valve layer and a valve cover layer. A plurality of bubble cell patterns are formed on the bubble layer with adhesive, glue or heat sealing. The valve layer is attached to bubble layer. A plurality of check valves are formed on the valve layer. An air opening is formed through each one of the plurality of check valves to inflate the plurality of bubble cells. The valve cover layer is attached to the valve layer. A row with at least one bubble cell is filled with air through the check valve. Inflation of the bubble cells cause the valve layer and valve cover layer to contact each other to seal the check valve.

Inflatable packaging with self-sealing fill channels having a first boundary layer, a second boundary layer, a first valve layer and a second valve layer are disclosed. The first and second valve layers are attached together to form a valve strip that has a plurality of valves and a lengthwise air channel in fluid communication with an entrance of each of the plurality of valves. Outermost, lengthwise edges of the first and second boundary layers are attached to each other and the valve strip is positioned between the first and second boundary layers with at least a portion of the lengthwise air channel not covered by the first and second boundary layers. A plurality of cross seams are formed in the first and second boundary layers and the portion of the valve strip positioned therebetween to define a plurality of inflatable cavities such as dunnage cavities or bubble cells.

End user filled protective packaging with self-sealing air bubbles includes a first bubble layer, a second bubble layer and a air channel layer. The first and second bubble layers are sealed together to form a plurality of bubble chambers. A plurality of bubble cells are formed in each bubble chamber by extending a plurality of air flow sealing lines. An air flow channel is formed between the second bubble layer and the air channel layer. One end of a cross air fill passage communicates with the air flow channel and the other end communicates with a fill opening in the second bubble layer. Air flows into each cross air flow passage and through the fill opening to inflate the bubble chamber. Inflation of the bubble chamber causes the plurality of air flow sealing lines to seal the cross air fill passage and prevent deflation of the bubble chamber.

A machine for making packages with labels is provided. The packaging machine utilizes a supply of packaging material in the form of a length of plain plastic tubing and a supply of labels in the form of a continuous strip thereof. In a previous cycle of the machine, the tubing was heat sealed along a transverse strip near the leading edge thereof. The strip is subsequently advanced a predetermined distance between a first set of jaws which close, with a first sealing wire carried by one of the jaws then energized to seal a leading edge of the tubing which will form the next package. A knife severs the tubing below that seal and the upper edges of the severed section which has been advanced are engaged by clamps. These move apart with the jaws to open the upper edges, thereby enabling an article to be dropped into the resulting pocket in the severed package section. The jaws then close once again and a second sealing wire below the clamps seals the upper edges of the severed section. The clamps are then released and the jaws open a second time so that the resulting package with the packaged article is discharged from the machine. During the above operations and prior to the jaws being opened the second time, the strip of labels is advanced and individual labels are severed therefrom. A severed label is formed into a V-shaped configuration by male and female V-shaped blocks and is then moved by the female block around the leading edge of the severed section having the transverse sealed strip. Third sealing wires carried by an additional set of jaws then seal the label to the severed package section near the transverse sealed strip.

End user filled protective packaging with self-sealing air bubbles includes a bubble layer, a valve layer and a valve cover layer. A plurality of bubble cell patterns are formed on the bubble layer with adhesive, glue or heat sealing. The valve layer is attached to bubble layer. A plurality of check valves are formed on the valve layer with adhesive, glue or heat sealing. An air opening is formed through each one of the plurality of check valves to inflate the plurality of bubble cells. The valve cover layer is attached to the valve layer. A row with at least one bubble cell is filled with air by applying a source of air at an entrance of the check valve. Inflation of the at least one bubble cell causes the valve layer and valve cover layer to contact each other to seal the check valve.
