Abstract
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.
Claims16
A knife holding assembly, including:
- a knife blade having opposed top and bottom surfaces and opposite ends defining end surface between the top and bottom surface and a longitudinally extending cutting edge formed thereon;
- a knife clamp for securing the knife blade;
- and
- a knife stop including,
- a cutting edge wherein the knife stop is located to engage one of said end surfaces of the knife and limits longitudinal movement of the knife blade relative to the knife clamp in the longitudinal extending direction of the cutting edge.
A knife holding assembly, including:
- a knife blade having a cutting edge;
- a knife clamp for securing the knife blade;
- a knife stop, wherein the knife stop includes a cutting edge and limits movement of the knife blade relative to the knife clamp;
- and a rotating base element, said knife blade being secured by the knife clamp on the rotating base element, and
- wherein the knife stop is secured to the rotating base element by at least one fastener.
A knife holding assembly, including:
- a knife blade having a cutting edge;
- a knife clamp for securing the knife blade;
- a knife stop, wherein the knife stop includes a cutting edge and limits movement of the knife blade relative to the knife clamp;
- and
- a second knife stop including a cutting edge,
- wherein the second knife stop further limits movement of the knife blade relative to the knife clamp.
A knife holding assembly, including
- a knife blade having a cutting edge;
- a knife clamp for securing the knife blade;
- a knife stop, wherein the knife stop includes a cutting edge and limits movement of the knife blade relative to the knife clamp;
- a retaining ring;
- and
- a knife block device,
- wherein the knife block is attached to the retaining ring and directly abuts the knife stop.
A knife stop for use in a circular wood processing machine having a rotating member for rotating at least one knife blade having opposed top and bottom surfaces and opposite ends defining end surfaces between the top and bottom surfaces and a longitudinally extending cutting edge, said knife blade being adapted to be mounted on the rotating member such that its cutting edge extends in radial direction relative to the rotating member, wherein the knife stop engages one of said end surfaces of the knife to limit movement of the at least one knife blade in a radial direction of the rotating member, the knife stop including:
- a sharp edge which forms part of a cutting edge along with the cutting edge of the at least one knife blade.
A wood processing apparatus, comprising:
- a rotating base member;
- a knife blade which is radially disposed on the rotating member, said knife blade having opposed top and bottom surface and opposite ends defining end surfaces between the top and bottom surfaces and a longitudinally extending cutting edge extending radially on the rotating member;
- a knife clamp for securing the knife blade to the rotating base member;
- and
- a knife stop engaging at least one of said end surfaces of the knife blade for limiting radial movement of the knife blade relative to the rotating base member, and
- said knife stop includes a cutting edge longitudinally adjacent to the cutting edge of the knife.
A wood processing apparatus, comprising:
- a rotating base member;
- a knife blade which is radially disposed on the rotating member;
- a knife clamp for securing the knife blade to the rotating base member;
- a knife stop disposed at an end of the knife blade for limiting radial movement of the knife blade relative to the rotating base member, said knife stop including a cutting edge;
- and a second knife stop including a cutting edge,
- wherein the second knife stop further limits radial movement of the knife blade relative to the rotating base member.
A wood processing apparatus, comprising:
- a rotating base member;
- a knife blade which is radially disposed on the rotating member;
- a knife clamp for securing the knife blade to the rotating base member;
- a knife stop disposed at an end of the knife blade for limiting radial movement of the knife blade relative to the rotating base member, said knife stop including a cutting edge;
- and at least one retaining ring surrounding the rotating member,
- wherein the knife stop is located at the end of the blade closest to the at least one retaining ring.
