Abstract: A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film conveyance mechanism that conveys a first film so that a trailing end portion of the first film heads toward a film splicing position for splicing to a leading end portion of a second film, a first sensor detecting a mark on the first film, a second sensor detecting the mark at downstream, and a controller for the film conveyance mechanism. The controller judges, based on detection of the second sensor, that the trailing end portion of the first film has reached the splicing position and stops conveyance of the first film. The controller controls the conveyance mechanism so that the conveyance speed of the first film before the detection of the mark by the first sensor is faster than the speed after the detection.
