<P>PROBLEM TO BE SOLVED: To provide a cutting unit allowing achievement of cleaner environment, and allowing achievement of various pouch shapes. <P>SOLUTION: This cutting unit 30 used for a bag-making device producing a plurality of containers from a belt-like wrapping material includes: a pair of blades 31 each having a cutting part 311; a support shaft 33 which turnably supports the pair of blades 31 such that the cutting parts 311 of the pair of blades 31 can symmetrically open/close in a state that the cutting parts 311 sandwich a symmetry axis, and is perpendicular to the symmetry axis; an opening and closing driving mechanism 30A by which opening and closing of the cutting parts 311 is carried out; and an attitude change drive mechanism 30B changing an attitude of the pair of blades 31 by swinging the pair of blades 31 with a swing shaft passing an optional intersection between the cutting parts 311 of the pair of blades 31 and extending in a direction perpendicular to both the symmetry axis and the support shaft 33 as a center. <P>COPYRIGHT: (C)2012,JPO&INPIT |
