Bag forming system edge seal |
摘要 |
A foam-in-bag assembly with a film feed mechanism which feeds film with a film driver and a bag forming assembly which includes an edge sealer that contacts film being fed by the film driver and which is supported on a moving member of the film feed mechanism and retains a fixed position relative to the moving member while in sealing engagement with the film being fed by the film driver. The edge seal assembly is preferably for use with a nip roller set and has a bearing through which a driving shaft of the nip roller extends and an edge wire is received on an edge wire support of the edge sealer. The support for the edge wire retains a fixed edge seal position while the driving member rotates within the sleeve.
