のロータリーカツターの駆動装置。[Claims for Utility Model Registration] (1) Mutual cooperative devices arranged on each side to sandwich the web in order to cut the continuous web fed at a predetermined speed at predetermined length intervals. A drive device for a rotary cutter comprising a cutter roller and a back-up roller, the drive device comprising: a first eccentric gear rotated at a constant speed by a drive motor; and a first eccentric gear meshed with the first eccentric gear. The cutter roller and the back-up are driven by the rotational force of the second eccentric gear, which is driven to rotate at unequal speeds by meshing with the first eccentric gear. A drive device for a rotary cutter, characterized in that the rollers are driven to rotate at unequal speeds to increase the circumferential speed of the cutter blade portion during cutting. (2) The drive device for a rotary cutter according to claim 1, wherein the speed of the drive motor is controlled according to the moving speed of the web.
