Abstract: An apparatus and method for the production of inflated cellular cushioning material, the apparatus comprising a dispensing unit comprising a feeding material roll, for feeding plastic material having sleeves or rows of cells, to be filled with air and a first and second conveyors for receiving the feeding material and holding such feeding material in a substantially flat position between the first and second conveyors.

Abstract: An inflatable cellular cushioning material having an air inlet pipe path to be inflated by an inflating device through the use of an air inlet pipe, the inflatable cushioning material comprising at least two layers of plastic pre-welded in such a manner so as to form a substantially diagonally oriented lines forming sleeves along the longitudinal axis of the inflatable cellular cushioning material and a substantially horizontal welded lines along the path of the air inlet pipe whereby the horizontal welded lines substantially reduce the non-inflated areas along the path of the air inlet pipe.

Abstract: Cellular cushioning material and a method for its production is described. In one scenario, the method includes providing a pre-welded sheet to a user comprised of at least two layers of plastic pre-welded to have a plurality of diagonally oriented, inflatable sleeves extending substantially the entire width of said sheet, and a longitudinally extending air entry passage. Each of the inflatable sleeves has an opening for allowing entry of air from said air entry passage into said sleeve. The user inflates the cellular cushioning material on an as-needed, real-time basis.

Abstract: A device and method for forming plastic pouches, the device including a source of at least two substantially superposed layers of plastic sheet, a pair of rollers for selectively advancing the layers of plastic sheet, a plastic filling element, and heat welding means for sealing open sides of the pouches, wherein portions of a longitudinal half of each of the rollers have a larger radius than the remainder of the roller whereby, when the larger radius portions of the rollers engage one another, they advance the plastic held between them, and when the smaller radius portions of the rollers are in registration with one another, they do not engage the plastic between them, so the plastic does not advance and can be heat sealed.
