Patent ID: 7546722

Claim:
A vertical filling-packaging machine comprising: a pair of flat part forming rollers disposed in opposition to each other across a cylindrical film for rotating while sandwiching the cylindrical film to carry the cylindrical film downward while forming a flat part in the cylindrical film; a sealing mechanism including a heater bar and a heater bar receiver for thermally sealing the flat part formed in the cylindrical film in a width direction thereof; a cutting mechanism disposed below said sealing mechanism and including a pair of members for cooling a thermally sealed part which has been thermally sealed by said sealing mechanism, and a cutter for cutting the thermally sealed part; and a driving mechanism for integrally holding said sealing mechanism and said cutting mechanism, and for integrally moving said sealing mechanism and said cutting mechanism along a direction in which the cylindrical film is carried, wherein said driving mechanism comprises: a supporter for integrally supporting said sealing mechanism and said cutting mechanism, a supporting shaft for supporting said supporter for linear movement in a direction along the direction in which the cylindrical film is carried, and a driving source for moving said supporter along supporting shaft.
