  • Automatic paper-web splicing system and method
    Patent number: 6096150
    Abstract: An automatic paper-web splicing system rotates a new paper roll being spliced, causes the peripheral speed thereof to agree with the traveling speed of a traveling web, and splices the start end of the new paper roll to the traveling web. The automatic paper-web splicing system directly detects via a detection mark provided on the outer peripheral surface of a new paper roll being spliced to a traveling web that the outer peripheral surface of the new paper roll is moved by a predetermined length by the rotation of the new paper roll, causes the time required for the new paper roll to move to agree with the time required for the traveling web to travel over the predetermined length, thereby causing the peripheral speed of the new paper roll to agree with the traveling speed of the traveling web, and carries out automatic splicing in this state.
