A film processing method for automatically connecting a film of a first film roll and a film of a second film roll to be exchanged with the first film roll in a packaging machine, comprising: holding the film of the first film roll at a holding position by a holding device, while the first film roll is supported by a robot, and the film of the film roll is unwound from the first film roll and extends to a former in a tensioned state; operating a cutting device (222A, 222B) for automatically cutting the film of the first film roll at a cutting position on an upstream side of the holding position with respect to a feeding direction toward the former while the film is held by the holding device; operating the robot for moving the first film roll having the film automatically cut to a storage section, so that the first film roll is stored at the storage section, wherein the storage section is located within a movable range of the robot and stores the second film roll; operating the robot for taking out the second film roll from the storage section, rotatably supporting the second film roll, and moving the second film roll to a connecting position where a film leading end of a film of the second film roll overlaps with a film terminal end of the film of the first film roll remained on a downstream side of the cut position and held by the holding device; connecting the film leading end of the film of the second film roll and the film terminal end of the film of the first film roll by a connecting device at the same time the film leading end overlaps with the film terminal end or after the film leading end has overlapped with the film terminal erid; and characterized by operating the robot for moving the second film roll from the connecting position to a set position spaced from the connecting position after connecting the films (30F, 40F) by the connecting device, so that the film of the second film roll is tensioned for feeding to the former. holding the film of the first film roll at a holding position by a holding device, while the first film roll is supported by a robot, and the film of the film roll is unwound from the first film roll and extends to a former in a tensioned state; operating a cutting device (222A, 222B) for automatically cutting the film of the first film roll at a cutting position on an upstream side of the holding position with respect to a feeding direction toward the former while the film is held by the holding device; operating the robot for moving the first film roll having the film automatically cut to a storage section, so that the first film roll is stored at the storage section, wherein the storage section is located within a movable range of the robot and stores the second film roll; operating the robot for taking out the second film roll from the storage section, rotatably supporting the second film roll, and moving the second film roll to a connecting position where a film leading end of a film of the second film roll overlaps with a film terminal end of the film of the first film roll remained on a downstream side of the cut position and held by the holding device; connecting the film leading end of the film of the second film roll and the film terminal end of the film of the first film roll by a connecting device at the same time the film leading end overlaps with the film terminal end or after the film leading end has overlapped with the film terminal erid; and characterized by operating the robot for moving the second film roll from the connecting position to a set position spaced from the connecting position after connecting the films (30F, 40F) by the connecting device, so that the film of the second film roll is tensioned for feeding to the former.
