A vertical filling-packaging machine capable of satisfactorily forming a heat- seal part by heat-sealing, cooling, and cutting a cylindrical film without moving and also manufacturing a variety of packaging bags with different outline shapes. The vertical filling-packaging device comprises a pair of flat part forming rollers disposed oppositely to each other through the cylindrical film (60) and carrying the cylindrical film (60) downward while forming a flat part (60a) on the cylindrical film (60), a seal mechanism having a heater bar (31) and a heater bar receiver (32) for heat-sealing the flat part (60a) in the lateral direction, a cutting mechanism disposed on the lower side of the seal mechanism and having a pair of cooling bars (34a) and (34b) for cooling a heat-sealed lateral seal part (65) and a cutter (35) for cutting the lateral seal part(65), and a drive mechanism integrally holding the seal mechanism and the cutting mechanism and integrally moving these mechanisms along the carrying direction of the cylindrical film (60).

Machine verticale de remplissage et d'emballage servant à former convenablement un joint thermique par thermoscellage, refroidissement et sectionnement d'une pellicule cylindrique sans bouger, ainsi qu'à produire des sacs d'emballage de formes différentes. Le dispositif vertical de remplissage et d'emballage comprend une paire de rouleaux de formation de partie plate placés de part et d'autre de la pellicule cylindrique (60), qui déplacent la pellicule cylindrique (60) vers le bas tout en y formant une partie plate (60a), un mécanisme de scellement doté d'une barre chauffante (31) et d'un récepteur de barre chauffante (32) pour le thermoscellage de la partie plate (60a) en direction latérale, un mécanisme de sectionnement placé sur le côté inférieur du mécanisme de scellement, doté d'une paire de barres de refroidissement (34a et 34b) qui refroidissent la partie latérale thermoscellée (65) et d'un outil de sectionnement (35) qui coupe la partie latérale thermoscellée (65), ainsi qu'un mécanisme d'entraînement retenant entièrement le mécanisme de scellement et le mécanisme de sectionnement et déplaçant complètement ces mécanismes dans le sens du déplacement de la pellicule cylindrique (60).
