A system includes a supply of an inflatable web () and a nozzle (). The inflatable web includes chambers (), an inflation channel (), and cross seals () between the inflation channel and the chambers. The inflatable web also includes ports () that pass through the cross seals to permit gas to pass from the inflation channel to the chambers. The nozzle has an outlet () configured to insert gas into the inflation channel as the inflatable web is moved in a downstream direction. The system is configured to feed the inflatable web along a path from the supply and past the nozzle in the downstream direction. The system is configured to hold the supply of the inflatable web with respect to the nozzle such that the cross seals contact the nozzle and rides along a portion of the nozzle as the inflatable web is moved in the downstream direction.

Passive tracking for inflatable webs along inflation nozzle

An inflator inflates inflatable webs. The inflator includes a web supply holding device that holds a supply of an inflatable web, a first gas moving device having a first inlet for receiving gas and a first outlet for expelling gas, a second gas moving device having a second inlet for receiving gas and a second outlet for expelling gas, and a nozzle. The first outlet is coupled to the second inlet such that gas expelled from the first outlet is received by the second inlet. The nozzle is coupled to the second outlet and inserts gas expelled from the second outlet into the inflatable web to inflate the inflatable web. Parameters of the first and second gas moving devices are selected based on a type of the inflatable web.

Inflators for inflatable webs with gas moving devices in series

An inflatable web includes an inflation zone, a first inflatable panel in fluid communication with the inflation zone, and a second inflatable panel in fluid communication with the inflation zone. The first inflatable panel includes a first sheet juxtaposed on a second sheet. The first and second sheets are sealed together to form inflatable chambers. The second inflatable panel include a third sheet juxtaposed on a fourth sheet. The third and fourth sheets are sealed together to form inflatable chambers. The inflatable film is configured to be inflated by an inflation and sealing machine configured to direct gas into the inflatable chambers of the first and second inflatable panels via the inflation zone and to individually seal the inflatable chambers of the first and second inflatable panels.
