SOLUTION: A movable support frame 63 is supported on a base 61 through a width direction position adjusting mechanism 62, and a lift support frame 65 is supported on the movable support frame 63 through a height adjusting mechanism 64. Further, cam plates 81 and 82 are mounted on the lift support frame 65. In addition, a movable member 95 which orbits along inner cam grooves 81a and 82a and outer cam grooves 81b and 82b, is provided on the cam plates 81 and 82. The belt material 21 transferred in such a state that it is placed on a tray 23 is pressed upward by a movable member 95 to the peripheral face, at the lower end, of the belt tight-wrapping drum 12 and the belt material 21 is brought into tight contact with the peripheral face of the drum 12. |
