Packaging filler product

A machine for producing inflated pouches or cells in situ to be used as packaging fillers comprising:

• a stand having a base plate supporting an upper plate in fixed spaced-apart relationship therewith;
• a length of folded or tubular sheet material adapted to move between said base plate and said upper plate from a supply station to a cutter station;
• said tubular sheet material being divided into a plurality of open end pouches separated by a seam;
• inflation means carried on said upper plate for inflating each of said pouches via said open end;
• sealing means carried on said upper plate immediately adjacent to said inflation means for sealing each of said pouch open ends to capture and retain said pouches in an inflated condition;
• a cutting element carried on said upper plate adjacent to said sealing means at said cutting station for trimming an edge marginal region of said sheet material adjacent to said sealed pouch open ends;
• means carried on said upper plate between said inflation means and said supply station for releasably gripping said edge marginal region to advance said sheet material past said inflation means, said sealing means and said cutting means;
• detachable means provided on each of said seams for separating adjacent ones of said pouches from each other;
• said supply of said sheet material is carried on a roll at said supply station;
• and
• said gripping and advancing means includes a pair of endless belts having external surfaces engageable with opposite edges of said edge marginal region of said sheet material for moving said sheet material between said upper plate and said base plate.

A machine for producing inflated pouches of cells in situ with air to be used as packaging fillers comprising:

• a stand having a base plate supporting an upper plate in fixed spaced-apart relationship therewith;
• a length of folded or tubular sheet material adapted to move between said base plate and said upper plate from a supply station to a cutter station;
• said tubular sheet material being divided into a plurality of open end pouches separated by a seam;
• air inflation means carried on said upper plate for inflating each of said pouches with air via said open end;
• said inflation means includes a source of pressurized air including an air supply conduit terminating with a plurality of discharge orifices;
• sealing means carried on said upper plate immediately adjacent to said inflation means for sealing each of said pouch open ends to prevent air from escaping and to capture and retain said pouches in an inflated condition;
• a cutting element carried on said upper plate adjacent to said sealing means at said cutting station for trimming an edge marginal region of said sheet material adjacent to said sealed pouch open ends;
• means carried on said upper plate between said inflation means and said supply station for releasably gripping said edge marginal region to advance said sheet material past said inflation means, said sealing means and said cutting means;
• detachable means provided on each of said seams for separating adjacent ones of said pouches from each other;
• said supply of said sheet material is carried on a roll at said supply station;
• and
• said gripping and advancing means includes a pair of endless belts having external surfaces engageable with opposite sides of said edge marginal region of said sheet material for moving said sheet material between said upper plate and said base plate.
