PURPOSE:To make a vertical heat sealing part installed to a vertical heat seal roll main body movable for adjustment while being prevented from becoming eccentric against the shaft centerline of the vertical heat seal roll main body. CONSTITUTION:Clamping bolts 41 are tightened by screwing down to the outer circumferential face of a vertical heat seal roll main body 25 through a tapered ring 39, and thereby a tapered thin part 37 provided to the boss 34 of a vertical heat sealing part 33 can be fitted uniformly with its diameter contracted, making the vertical heat sealing part 33 installed and fixed to the vertical heat seal roll main body 25 movable for adjustment while being prevented from becoming eccentric against the shaft centerline of the vertical heat seal roll main body 25. |
