Abrégé

A device for processing wood and other material is described. A planer head, typically used in wood processing, has a cylindrical body which rotates around an axis and comprises one or multiple cutting knives. The knives are held in place by a knife holder. The knife holder is placed in the cylindrical body by insertion into holes in the cylindrical body and held in place through a fastening assembly comprised of a long and slender fastening member with a threaded end.

Abrégé

A planer head includes a cylindrical body having a first end, a second end and a crenelated curved face extending therebetween and including a plurality of pockets receiving a plurality of knives and knife holders. A clamping assembly connects each of the plurality of knife holders to their corresponding knives by frictional engagement. The clamping assembly includes at least one pair of clamping elements, each being disposed on a corresponding one of the first and second ends of the body. When moved in the longitudinal direction toward each other, the at least one pair of clamping elements forcing the plurality of knife holders in the radial direction thereby engaging in friction the knife holders with their corresponding knives and knife pockets of the body. A number of pairs of clamping elements is lower than a number of at least one of knives and knife holders. A kit for a planer head assembly, a clamping assembly, and a planer body are also presented.

A blade holder in a chipping device which has blade carriers that rotate in ongoing operation and blades attached to the blade carriers and being clamped in place with a clamping force via centrifugal forces that occur during rotation of the blade carriers in ongoing operation. The blades are attached to the blade carriers on a side that lies radially inward. There is at least one clamping element that lies radially inward of the blade carrier and is mounted on the blade carrier to rotate with the blade carrier. The clamping element exerts further clamping forces on the blade during rotation.

Abrégé

This invention relates to a cutting blade for a chipping machine, with the cutting blades being designed so that splitting blades extending at least essentially perpendicular to a cutting edge of the cutting blade are present, which project beyond the cutting edge and/or stand out from the cutting edge, with the cutting blade consisting of a blade support and a blade head, with the blade head corresponding with a friction fit to the blade support, and with the blade head being designed as a disposable component.
