ABSTRACT:
A jaw cylinder 30 includes a jaw cylinder body 31 and a folding jaw support 36 rotatably supported with respect to the jaw cylinder body 31, and two folding jaws 11 and 15 are attached to the jaw cylinder body 31 or the jaw cylinder support 36, respectively. The folding jaw 11 is rotated with respect to the folding jaw 15 so as to adjust a gap between the folding jaws 11 and 15 in accordance with the thickness of a product. At this time, a jaw cylinder driving helical gear 38 and a gap adjusting helical gear 39 are moved in an axial direction thereof by an adjusting unit 43 so that the jaw cylinder driving helical gear 38 or a folding cylinder driving helical gear 25 meshing with the helical gear 38 are rotated in a circumferential direction. On the other hand, a support rotating helical gear 37 is rotated in the circumferential direction through the gap adjusting helical gear 39 and intermediate gears 40 and 41 by an amount larger than a rotating amount of said jaw cylinder driving helical gear 38 or the folding cylinder driving helical gear 25.
