ABSTRACT:
An apparatus for making cushioning, shock absorbing, insulating or packaging material formed of webs of plastic material sealed together to make fluid or air filled cells in a quilted fashion. A tube forming roller forms tubes of the material. Heat sealing elements seal the webs into tubular formation and additional heat sealing elements seal the webs transversely across the tubular formation to form a series of cells. A fluid blower maintains fluid or air within the tubes during the cellular formation.
