  • Patent number: 6702275
    Abstract: In a paper-leaves separating/supplying apparatus comprising a rotary separating/supplying belt, a vacuum suction device and a separating/supplying device, the vacuum suction device takes up one by one a plurality of paper leaves set together and conveyed as far as a position at which they come into contact with a belt surface of the separating/supplying belt so that the paper leaf is attached onto the belt surface and is fed toward the downstream side in accordance with the rotary motion of the separating/supplying belt. The belt surface of the separating/supplying belt is placed in a state perpendicular to a traveling plane of the paper leaves or in a state inclined toward the paper leaves.

  • Patent number: 6629691
    Abstract: In a paper-leaves conveying means for conveying a plurality of paper leaves, set together in a bundle in a depositing section, toward a paper-leaves feeding position where a separating/supplying belt exists, an arm is provided which is designed to be moved toward the paper-leaves feeding position in a protruding condition into the interior of the depositing section for supporting side surfaces of the paper leaves, and further to be retreated instantaneously from the interior of the depositing section immediately before the last paper leaf existing between the arm and the separating/supplying belt is handed over to the separating/supplying belt side. Thus, the arm can support the paper leaves until immediately before they are handed over to the separating/supplying belt, which eliminates the occurrence of the falling-down of the paper leaves at the paper-leaves feeding position.
