Abstract
A variable length rotary cutting system for cutting sheet material in various desired cut lengths, including a knife roll and an anvil roll between which the sheet material is passed for cutting. A drive system drives the knife roll at varying speeds during a cycle of rotation and includes a drive gear and an offset gear mounted in an off-center mounting so as to be rotated at varying speeds by the drive gear. The rotation of the offset gear is transmitted to the knife roll so as to cause the knife roll to rotate at varying speeds about a cycle of rotation to enable the knife roll to cut varying lengths of the sheet material.
