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: 7681609Abstract: A wood working knife for use in a wood working machine, comprising a knife body having a first cutting edge and an opposed second cutting edge, the knife body having a first clamping surface and a second clamping surface. The first clamping surface has opposed clamping features separated by a middle section, the opposed clamping features and the middle section being sized and shaped such that, upon the knife body being inserted into a clamping assembly, the clamping forces are localized towards the opposed cutting edges and away from the middle section.Type: GrantFiled: August 20, 2008Date of Patent: March 23, 2010Assignee: Iggesund Tools ABInventors: Sven-Olov Biller, Mathieu J.

Patent number: 6058989Abstract: A self aligning knife clamping assembly and machine incorporating the same are disclosed. In one embodiment there is provided a knife clamping assembly having an upper clamping component, a lower clamping component and a fastening device, such as a bolt, therebetween, to permit the clamping components to be releasably clamped together onto a knife element having a knife edge. Positioned between the knife element and the clamping assembly is a biasing element, which urges the knife element to enter, or remain in, a preferred position prior to the knife element being immovably clamped into place. In the preferred embodiment the biasing element is in the form of an elastomeric strip.Type: GrantFiled: September 23, 1998Date of Patent: May 9, 2000Assignee: Iggesund Tools ABInventors: Daniel M. LaGrange, Sven-Olov Biller
