Apparatus and method for forming inflated containers |
| 摘要 |
A device for producing a longitudinal seal between two juxtaposed plies of film that are conveyed along a longitudinal path of travel, the juxtaposed film plies including a series of containers therebetween, wherein the device includes a sealing mechanism that forms a sealing zone in the travel path in which the longitudinal seal is produced, and a pressure mechanism that forms a pressure zone in the travel path in which the juxtaposed film plies are compressed, the pressure zone being positioned between the containers and the sealing zone. |

1. A device for producing a longitudinal seal between two juxtaposed plies of film that are conveyed along a longitudinal path of travel, the juxtaposed film plies including a series of containers therebetween, said device comprising:
a. a sealing mechanism that forms a sealing zone in said travel path in which said longitudinal seal is produced; and b. a pressure mechanism that forms a pressure zone in said travel path in which the juxtaposed film plies are compressed, said pressure zone positioned between the containers and said sealing zone to substantially isolate the containers from said sealing zone, wherein said pressure mechanism comprises a pair of pressure members that converge within said travel path to form said pressure zone, said pair of pressure members comprising a pair of belts. |
