Japanese Patent JP2943110

B1

An arbitrarily positioned longitudinal perforation forming apparatus includes a longitudinal roulette cylinder composed of a first rotary shaft arranged on one side of a continuous web paper and at least one disc-shaped longitudinal roulette edge supported on the first rotary shaft so as to be adjustably positioned in an axial direction of the first rotary shaft. The apparatus further includes a receptacle cylinder composed of a second rotary shaft arranged on the other side of the continuous web paper in parallel relationship with the first rotary shaft and at least one disc-shaped edge receptacle plate supported so as to be adjustably positioned in an axial direction of the second rotary shaft. A projecting edge receptacle portion on the outer periphery of the edge receptacle plate opposes the longitudinal perforation edge of the longitudinal roulette cylinder. A drive system drives the first rotary shaft of the longitudinal roulette cylinder and the second rotary shaft of the receptacle cylinder in synchronism with the travel of the continuous web paper. An edge receptacle plate switchover moving device engages the edge receptacle plate to move the edge receptacle plate in the axial direction, and a first control unit controls the edge receptacle plate switchover moving device.
