Inflation and sealing device with rotary cutter

An inflatable-cushion inflation and sealing device, comprising:

• an inflation assembly including a fluid conduit configured for inflating with a fluid a cushion cavity disposed between first and second layers of film and configured for longitudinal reception between first and second overlapping portions of an inflation channel adjacent to and in fluid communication with the cushion cavity, the fluid conduit including a recessed portion;
• a driving mechanism configured to pull the inflation channel in a longitudinal direction over the fluid conduit and through a sealing assembly;
• a rotary cutting element disposed proximate the fluid conduit, wherein the rotary cutting element partially extends into the recessed portion of the fluid conduit, the rotary cutting element configured and oriented to longitudinally cut open the inflation channel from about the fluid conduit in the longitudinal direction by a cutting motion that includes rotation of the rotary cutting element;
• and
• the sealing assembly configured to seal the overlapping portions to each other and to form a longitudinal seal configured to seal the fluid in the cushion cavity.

An inflatable-cushion inflation and sealing device, comprising:

• an inflation assembly configured for inflating with a fluid a cushion cavity disposed between first and second layers of film, the inflation assembly including a fluid conduit having a cutting element opening configured for longitudinal reception between first and second overlapping portions of an inflation channel adjacent to and in fluid communication with the cushion cavity;
• a cutting element located at least partially in the cutting element opening of the fluid conduit disposed proximate the fluid conduit and configured and oriented to cut open the inflation channel by a cutting motion that includes rotation of the cutting element;
• and
• a sealing assembly disposed adjacent the cutting element and configured to seal the overlapping portions to each other and to form a longitudinal seal configured to seal the fluid in the cushion cavity.
