<P>PROBLEM TO BE SOLVED: To provide a bag making machine in which vertical positioning of sealing bars can easily be performed in a short time at a heat sealing step. <P>SOLUTION: There is disclosed the bag making machine in which a multilayer film having a hot-melt layer is held between the upper and lower sealing bars and the held film is heat-sealed by applying heat and pressure thereto. The bag making machine includes: an upper side sealing bar holding unit; a lower side sealing bar holding unit; a first longitudinal direction position adjustment mechanism; a first lateral direction position adjustment mechanism; a first rotative direction position adjustment mechanism; a second longitudinal direction position adjustment mechanism; a second lateral direction position adjustment mechanism; a second rotative direction position adjustment mechanism; a first longitudinal direction displacement amount measuring means; a first lateral direction displacement amount measuring means; a second longitudinal direction displacement amount measuring means; and a second lateral direction displacement amount measuring means, so that the positioning of the upper and lower sealing bars is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
