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: 6938656Abstract: A wood processing device having a spinning wood processing head having one or more spaced apart knives mounted on said spinning head for processing wood. The knives, upon contacting said wood, form a curved cut surface in said wood being processed. At least one limit surface is adjustably mounted between said one or more knives on said spinning head, said limit surface being sized and shaped to limit abnormal movement of said wood during processing. An adjustor for adjusting a position of said limit surface is provided to permit said limit surface to limit abnormal movement of said wood over a range of operating conditions. In a preferred embodiment the limiter is curved. A method of adjusting a wood processing head is also disclosed.Type: GrantFiled: October 2, 2002Date of Patent: September 6, 2005Assignee: Iggesund Tools ABInventors: Christian Plouffe, Ian G. Zinniger
