Machine and method for inflating and sealing inflatable packing mats

[Abstract] The present invention discloses a method and a machine made inflatable packing cushions from film material preform (11) into a roll, the roll having a preformed film material charging passage (19) extending longitudinally adjacent one end of the material, and by A chamber (21, 22) that laterally extends the passage (23) in communication with the passage (19). The film material is fed from the roll (28) to an inflation tube (52) extending into the inflation channel. Air is introduced into the chamber (21, 22) through the inflation tube (52) to inflate the cushion. A longitudinally extending seal (89) after the cushion is inflated is formed as a passage (23) across the passage (19) and the chamber (21, 22).
Sovereign item [1] A method for inflating inflatable cushion packaging and sealing machine, comprising: a roll of prefabricated film material having two layers, the two layers are sealed together to form a longitudinal edge of the vicinity of a material extending charging passage, through the rows extending across the material in the chamber, the flow path of the chamber interconnected in each row, and between the inlet and the inflatable channels in each row wherein a chamber extending passage; a pair of spaced apart, horizontally extending rollers, the film roll of material positioned on one of said pair of rollers; inflatable tube connected to an air source, and extends into the pneumatic passage to introduce air into said chamber, thereby inflating said cushion; sealing unit, after the cushion is inflated, the sealing unit for forming a longitudinally extending seal across the inlet passage; and a volume from the inflation tube through the sealing unit and feed the film material s installation.
