A methods of executing start, run, and stop sequences on a machine for converting a web of preformed pouches into inflated dunnage units. The pouches are defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge.

A packaging apparatus with an improved pinch roller apparatus, fluid supply apparatus, and/or a sealing apparatus. The pinch roller apparatus (e.g., comprising one or more guide and/or pinch rollers) is used to deliver film material to the fluid supply apparatus (e.g., nozzle and blower apparatus, or the like) that fills one or more chambers of the film material with fluid (e.g., air, gas, or other like fluid), and the film material is then sealed by a sealing apparatus (e.g., using one or more heating elements with an improved temperature sensor configuration) that seals the fluid within the one or more chambers in order to form the inflated article (e.g., inflated packaging material). In particular, the sealing apparatus provides improved sealing through the improved accuracy of the temperature reading in the heating zone, in part, by locating a sensor between a heating element and a protective member that covers the sensor.

An inflatable protective packaging unit and associated inflation systems are disclosed. The unit can include an inflatable component that includes overlaid flexible plies connected to each other to define a fluid chamber therebetween. The inflatable component can define an inflation region in fluid communication with the fluid chamber to allow fluid from the inflation region into the fluid chamber. The unit can further include a receiver separably attached to the inflatable component at the inflation region and configured to direct fluid into the inflation region. The inflation system can be configured to discretely engage the inflatable protective packaging unit and provide fluid for inflation. Once inflated, the system may eject the unit, and cause the inflatable component to separate from the receiver.

An output chute safety mechanism includes an output chute, an output chute valve door, and an upstream valve door. The output chute includes a proximal end and a distal end. The output chute valve door includes a first configuration that obstructs the output chute and a second configuration that does not obstruct the output chute. The upstream valve door includes a first configuration that prevents the output chute valve door from being disposed in its second configuration and a second configuration that permits the output chute valve door to be disposed in its second configuration.

Various devices and methods for expanding and dispensing expandable slit sheet paper include a support member for a roll of expandable slit sheet paper. In some embodiments, the roll of expandable slit sheet paper has an interior core member and a roll of expandable slit sheet paper wound on said interior core member. The device preferably includes a tension device that is used to provide tension to resist rotation of the roll or the movement of the expandable slit sheet paper during use. The pressure of the tensioning device creates a friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.

Packaging material is provided. The packaging material can include at least one web layer having a surface that includes first and second regions. When corresponding first regions are overlaid with each other and corresponding second regions are overlaid with each other, the overlaid first and second regions can cooperatively surround a cavity. The packaging material further can include a first sealing material disposed in the first region and configured to seal together the corresponding first regions upon application of first conditions to the first sealing material, and a second sealing material disposed in the second region and configured to seal together the corresponding second regions upon application of second conditions to the second sealing material. The second sealing material can be configured such that the first conditions applied to the second sealing material are insufficient to cause the second sealing material to seal.

A Coiling device for spirally rolling-up a three-dimensional cushioning material made by a cushion forming device from a web-type source material (e.g. a roll or a Leporello-stack) of paper, can include a reel having at least two deflectors, and having a rotational axis extending in vertical direction. The deflectors can be a mandrel, hook, deflector edge, or the like.

The invention relates to a device for dispensing a cushion means for packaging purposes, comprising a dispensing means which provides the cushion means, and a withdrawal region from which a user can take the dispensed cushion means. At least one sensor means is present, which detects an engaging of the dispensed cushion means by the user and/or the presence or absence of at least one region of a hand of the user in the withdrawal region or in a detection region adjacent to the withdrawal region. The providing device dispenses a cushion means depending on the detected engaging of the dispensed cushion means by the user and/or depending on the presence and/or absence of a hand of the user in the withdrawal region or in the detection region.

A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism. The sealing mechanism includes a heating zone and a cooling zone. The sealing mechanism also includes a heating element that extends along both the heating zone and the cooling zone, with the heating element having a first profile in the heating zone and a second profile in the cooling zone.
