Patent number: 10245751Abstract: A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to the fulcrum at a position outside of the clamping component at a location farther askew of the clamping axis than the fulcrum.Type: GrantFiled: March 15, 2013Date of Patent: April 2, 2019Assignee: ANDRITZ IGGESUND TOOLS ABInventors: Ian G. Zinniger, Mathieu J. A. Gouin, Daniel M. LaGrange

Patent number: 8281826Abstract: A sharp edged knife stop can secure the position of knife blades in a cutting or chipping system and prevent the separation of knife blades. The sharp edged knife stops can also assist in the cutting or chipping and lower the amount of debris build up that would occur with the use of traditional knife stops. The sharp edged knife stop has the same inclination angle as the knife blades and the same difference in knife edge height as the knife blades above that of a retaining ring height.Type: GrantFiled: October 22, 2008Date of Patent: October 9, 2012Assignee: Iggesund Tools ABInventors: Robert L.

Patent number: 8082958Abstract: A knife includes first and second edges, a ridge, a concave surface, and a planar surface. The edges are defined by intersections of outer edge forming surfaces on an outer side of the knife and inner edge forming surfaces on an inner side of the knife. The ridge is on the inner side and the crest of the ridge is parallel to the first and second edges. The concave surface is between an inner edge forming surface and the ridge, and the planar surface is adjacent to the concave surface and between that first inner edge forming surface and the concave surface. A reference plane intersects the first and second edges, and a distance between any point on the concave surface and the reference plane is not less than a distance between any point on the planar surface and the reference plane.Type: GrantFiled: October 24, 2008Date of Patent: December 27, 2011Assignee: Iggesund Tools ABInventors: Mats Engnell, Aaron J.
