Abstract
An orbital knife including a support structure; a yoke rotatably attached to the support structure constituting a yoke hub and a plurality of yoke arms; one or more rotatable knife rolls securely connected to at least one of the plurality of yoke arms; one or more blades attached to each of the one or more knife rolls and including a cutting element; one or more sun gears rotatably attached to the support structure; an anvil roll rotatably attached to the support structure; and one or more planet gears wherein each knife roll has rotatably attached thereto at least one planet gear and each planet gear is mated with a sun gear.
Claims19
An orbital knife comprising:
- a. a support structure;
- b. a yoke rotatably attached to the support structure having a yoke axis of rotation, wherein the yoke comprises a yoke hub and a plurality of yoke arms;
- c. one or more rotatable knife rolls radially displaced from and parallel to the yoke hub and securely connected to at least one of the plurality of yoke arms wherein each knife roll has an axis of rotation;
- d. one or more blades attached to each of the one or more knife rolls and comprising a cutting element parallel to the knife roll to which the blade of such cutting element is attached;
- e. one or more sun gears rotatably attached to the support structure wherein each sun gear has (1) an axis of rotation concentric with the yoke axis of rotation, and (2) associated therewith a sun gear pitch radius;
- f. an anvil roll rotatably attached to the support structure and having an axis of rotation parallel to the yoke axis of rotation;
- and
- g. one or more planet gears, each with a planet gear axis of rotation and a planet gear pitch radius, wherein (1) each knife roll has attached thereto at least one planet gear, (2) each planet gear is mated with one of the one or more sun gears forming a gear train wherein the sun gear drives the planet gear and in each such gear train the planet gear pitch radius is substantially tangential to the sun gear pitch radius, and (3) the planet gear axis of rotation of each planet gear is concentric with the axis of rotation of the knife roll to which the planet gear is attached.
