Summary:With a view toward reducing any seal failure of overlap portion of wrapping material rolled into tubular form, a bag making and packaging machine comprises forming means (13), longitudinal seal means(16) and a receiving member (31). The forming means (13) rolls a strip film into tubular form to thereby obtain a tubular film. The longitudinal seal means (16) carries out heat seal of overlap portion of the tubular film longitudinally along the direction of extension of the tubular film. The receiving member (31) is fitted to the forming means (13) at its position opposite to the longitudinal seal means (16), and cooperates with the longitudinal seal means (16) so as to interpose the overlap portion therebetween. The receiving member (31) has flexibility by which the overlap portion is pressed toward the longitudinal seal means (16).
