<P>PROBLEM TO BE SOLVED: To provide an end sealing device in a horizontal bag-making filler machine in which, in a simple structure, heat of a sealing body does not affect a film when the horizontal bag-making filler machine is stopped. <P>SOLUTION: A sealing unit 29 having a pair of sealing bodies 24, 28 installed vertically movably is arranged horizontally movably by being guided with slide guides 14, 14. A ball screw nut 34 provide on the sealing unit 29 is screwed on a screw rod 32a extended horizontally along with the film transfer direction. The screw rod 32a is rotated in normal and reverse direction by the first servomotor 33. A horizontal operating mechanism 30 composed of a ball screw 32 and the first servomotor 33 can change the position of the horizontal moving center of the sealing unit 29 set in accordance with a cut pitch backward and forward within a horizontally movable range. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
