An inflation method for an air cushion body which includes one or more air storing units formed by at least two air cell films, an inflation valve formed by at least two valve films, and an inflation unit integrally connected with the air storing units and formed by two inflation end portions overlapping with each other to define an inflation channel, includes the following steps: sealing off two ends of the inflation channel to form an inflatable cavity, filling air into the inflatable cavity where the air that enters the inflatable cavity enters the corresponding air storing units through the air inlet channel, and releasing the two ends of the inflation channel upon completion of inflation to acquire the air cushion body that is inflated.

The present invention relates to a welding machine for continuous welding of two layers of plastic film material together in a welding pattern, including a welding drum, welding means arranged on the peripheral surface of the welding drum that exhibits a welding pattern, a heating arrangement arranged to heat the welding means to a welding temperature, an endless welding band, a set of band guidance rollers comprising a first application roller and a second application roller arranged to apply the welding band to the welding means on the surface of the welding drum over a peripheral extend of at least 900? of the welding drum with a force radial to the welding drum in a first operational mode of the welding machine, the set of band guidance rollers comprising at least one displaceable tensioning roller for maintaining a tension of the welding band, a web guidance arrangement for guiding the two layers of plastic film material in between the welding drum and the welding band, and a control means for controlling the operation of the welding machine, wherein the machine comprises one or more separation rollers, and is arranged in a second operational mode of the welding machine to displace the one or more separation rollers from a first position thereof and in between the welding means on the peripheral surface of the welding drum and the two layers of plastic film material to a second position of the one or more separation rollers where the two layers of plastic film material and the welding band are separated from the periphery of the welding drum by means of the separation rollers. Furthermore is disclosed the use of such welding machine for forming pockets between the two layers of plastic film material, in particular closed pockets for air cushions.

A fluid-fillable air cushion or mailer comprising a first layer comprising a repulpable material, a laminate comprising at least two water-soluble material layers, the laminate adjacently affixed to the first layer; and an air fillable portion integral with the laminate, and method of making same are disclosed.

Devices are provided for dispensing pillows for use in packaging arranged in web and having relative a relatively thick portion bordered by relatively thin portions that adjoins the individual pillows within the web. The systems can include a transfer unit having a pushing member. The pushing member is configured to engage the web of pillows as the pushing member moves so that the pushing member draws the web into the transfer unit, and moves the web through the transfer unit and toward an exit opening of the transfer unit. The devices further can include a separation unit having a cutting device, and a movable cover that at least partially encloses the cutting device to prevent unintentional contact with the cutting device.

The present disclosure relates generally to an inflation and sealing machine and in particular to a method for modifying one or more parameters of the machine. The method includes identifying a configuration of a supply material to be used with the inflation and sealing machine, such as by receiving a user input, automatically detecting characteristics of the material, and/or receiving data such as from a sensor regarding the characteristics of the material. Once the configuration of the supply material is identified, the method includes receiving a selection of a prestored recipe according to a configuration of the supply material, where the recipe determines or sets the value for one or more operating parameters of the machine.

A machine for inflating and sealing an inflatable web, the web including opposing longitudinal edges and a pair of sheets sealed together by transverse seals that form a series of inflatable containers. The machine generally includes a support structure, a spool for supporting a roll of the inflatable web, a web conveyance system, an inflation system to inflate the containers, and a sealing device for sealing closed the openings of the containers.

A cushioning apparatus configured to be placed inside of a shipping container includes a plurality of inflation chambers. Each of the chambers is characterized as having a general shape, when inflated, of a truncated rectangular pyramid. Each of the plurality of inflation chambers is foldably coupled to another of the plurality of inflation chambers at an edge of said inflation chamber. The plurality of inflation chambers, when inflated, are configured to be folded into a shape that surrounds a void between said plurality of inflation chambers. There may be six inflation chambers.

A heating apparatus for an air cushion machine includes a hot sealing wheel, wherein a transmission wheel is respectively configured on two sides of the hot sealing wheel, an electrode plate is configured on an outer side of each transmission wheel, a guide cylinder seat is configured between the transmission wheel and hot sealing wheel, fixing guide cylinders are projected from the guide cylinder seat, the fixing guide cylinders are passed through the transmission wheel to be in electric contact with the electrode plate, heating sheets are configured inside the hot sealing wheel, each surface of the heating sheet is in electric connection with a conductive spring, another end of the conductive spring is configured with a carbon brush in rotational contact with the electrode plate, and the conductive spring and carbon brush are configured inside the fixing guide cylinder, thereby achieving high energy utilization, good temperature uniformity.

A packing machine and a method of use thereof for packing articles in airbags. The packing machine includes three consecutive stations that can receive airbags in a series of airbags one by one, wherein the article to be packed is placed in the airbag. The first station can receive a new bag containing the article. In the first station, the airbag can be horizontally sealed at the top to close the opening and can then be inflated. In the second station and the third station, the airbag can be vertically sealed and can then be dropped into a conveyor at the end of the third station. An air tube that extends between the first station and the second station can be used to inflate the airbags. Two linear actuators with gripping heads can move the airbags from between stations, and break the leading airbag from the series of airbags.

An airbag sealing structure, including: an airbag body; at least one opening portion, configured on the airbag body; at least one passage portion, configured inside the airbag body and positioned at one side of the opening portion, a diameter of the passage portion being smaller than 2.9 millimeters; at least one accommodation space far away from the side of the opening portion and configured on the passage portion; and at least one blocking portion, configured inside the accommodation space and positioned at one side of the passage portion. Thereupon, a pneumatic pump nozzle may be inserted in the opening portion of the airbag body to fill air into the airbag body, air will then enter the accommodation space through the passage portion to inflate the accommodation space; when the accommodation space is saturated with air, the airbag body will seal the passage portion; thereafter, the passage portions are hot-sealed immediately.
