ABSTRACT:
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 includes an upper blade roll with a blade and a lower blade roll with an anvil element. Each of the individual sheets cut from the first web is arranged to be guided and transferred onto the second web while the first web is being sucked onto an outer peripheral surface of the lower blade roll by the suction through suction holes formed in a first region on an outer peripheral surface of the lower blade roll. The first region defined as a suction region includes a plurality of the suction holes and a non-suction region does not include the suction holes. The suction region and the non-suction region are provided alternately in a roll rotating direction.
