Intermittent cutting transferring device

An intermittent cutting transferring device configured to cut a first web into individual sheets and to intermittently transfer the individual sheets onto a second web being continuously fed, said device comprising:

• an upper blade roll including a blade on an outer peripheral surface thereof;
• and
• a lower blade roll including, on an outer peripheral surface thereof, an anvil element and a plurality of suction holes,
• wherein
• the upper blade roll and the lower blade roll are rotatable in opposite roll rotating directions at approximately the same peripheral velocity which is higher than a velocity in which the first web is fed to the lower blade roll, and equal to or lower than a feeding velocity of the second web,
• the blade and the anvil element are configured to guide the first web therebetween while the first web is being sucked onto the outer peripheral surface of the lower blade roll by a suction through the plurality of suction holes formed in a first region of the outer peripheral surface of the lower blade roll,
• the blade and the anvil clement are adapted to be brought into contact with each other to intermittently cut the first web into the individual sheets,
• each of the individual sheets cut from the first web is arranged to be guided and transferred onto the second web while the sheet is being sucked onto the outer peripheral surface of the lower blade roll by a suction through the suction holes formed in a second reaction on the outer peripheral surface of the lower blade roll,
• the first region includes a suction region in which the plurality of the suction holes are formed and a non-suction region. free of said suction holes,
• the suction region and the non-suction region are provided alternately in the roll rotating direction of the lower blade roll,
• the suction region includes
• a center region elongated in the roll width direction,
• first and second inclined regions, in which the suction holes are arranged in rows inclined to the roll width direction, and which are located at end sections of the center region, and
• first and second distant regions spaced in the roll width direction from the first and second inclined regions, respectively,
• the rows of suction holes in the first and the second inclined regions converge toward each other in the roll rotating direction of the lower blade roll, and
• the suction holes in the first and second distant regions are arranged in rows that are approximately parallel to the rows of the first and second inclined regions, respectively.
