As described above, according to the first aspect of the invention, when the tape is wound around the small bundle group to form a cross shape, the small bundle group is formed by the table means and the clamping means. Since the tape is wound around the circumference only once and bound by the fastening means, the consumption of the tape can be reduced to half of the conventional amount.

Further, according to the second aspect of the present invention, the starting end of the tape is clamped by a plurality of clamp plates to wind the tape around the small bundle group, and after the bundling is completed, the plurality of clamps are clamped. Since the clamped state of the tape held by the clamp plate is released by the load means provided on one side of the plate, even if the tape is wound around the small bundle group only once, it is bound with a sufficiently strong force. In addition, it is possible to smoothly move up the small bundle group when moving up the small bundle group after binding.

Further, according to the third aspect of the present invention, since the tape anti-slip means is provided on each of the plurality of clamp plates for holding the start end of the tape, it is possible to wind the tape with the start end securely held. At the same time, the small bundle group can be tightened with a sufficient force even if it is only wound once.

Further, according to the invention of claim 4, since the lifting table for moving the small bundle group up and down can be set in the recess of the table means, the space required for the lifting table to move up and down is minimized. As a result, the machine for binding a large bundle of paper sheets can be made compact.

According to the fifth aspect of the invention, when receiving the swirled small bundle group, the elevating table urged upward is brought into contact with the lower end of the small bundle group held by the large bundle swiveling means. I tried to receive it without any drop,
It is possible to prevent the small bundle group from falling on the lifting table.

Further, according to the invention of claim 6, the small bundle group is held by a pair of clamp rods provided at a position slightly displaced from the position of the center of gravity of the small bundle group, and further, the small bundle group is held only by its own weight. Since the pair of clamp rods are rotated to rotate the small bundle group, the mechanism itself can be simplified and the small bundle group can be reliably rotated.

Further, according to the invention described in claim 7, since the tapes are heat-bonded by the heating member supported at four points via the elastic member, even if the tape surface is inclined, heat is applied. The heat-pressure contact surface of the member can be pressed uniformly against the entire tape surface, and the tapes can be reliably heat-bonded.
