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 at least one blade on an outer peripheral surface thereof;
• and
• a lower blade roll including, on an outer peripheral surface thereof, at least one anvil element and a plurality of suction holes,
• wherein
• the upper blade roll and the lower blade roll are rotatable in opposite moving 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 suction holes formed in a first region on the outer peripheral surface of the lower blade roll,
• the blade and the anvil element 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 region on the outer peripheral surface of the lower blade roll,
• the cut sheet is arranged to be sucked onto the outer peripheral surface of the lower blade roll at a position where both side edge regions of the cut sheet and a front end region of the cut sheet face an edge area of the second region while a remaining region of the cut sheet faces a center area of the second region,
• the suction holes are arranged in both the center area and the edge area of the second region,
• a suction holding force in the edge area corresponding to said front end region and said side edge regions of the cut sheet is stronger than a suction holding force in the center area corresponding to said remaining region of the cut sheet, and
• at least one of the suction holding force in the edge area and the suction holding force in the center area is variable.
