Abstract
A method for the feeding of long pieces of wood into a disc chipper against a disc (3) equipped with blades in such a way that the piece of wood encounters the bladed disc at a sharp input angle, and a disc chipper. The sharp input angle is achieved by combining with the sharp inclination (.perspectiveto.) of the feeder chute (5) a sharp level slanting angle, whereupon the inclination of feeder chute (5) will be sufficient to feed wood against the blade disc.

A method for feeding a long piece of wood into a disc chipper having a disc equipped with blades rotating around a horizontal axis, comprising:
- feeding the piece of wood such the piece of wood encounters the disc at an input angle .beta., which is the angle between the piece of wood and a line in a plane in which the disc is located, wherein said line passes through a point in the plane where said piece of wood contacts said disc and which extends tangentially in a direction in which the disc is moving at that point;
- said input angle .beta. includes an angle .omega., which is an angle between a projection of the piece of wood against the plane in which the disc is located and the horizon;
- said angle .omega.being less than 90.degree.;
- said input angle .beta. further includes an angle .gamma., which is an angle between a projection of the piece of wood against a floor surface and the plane of the disc;
- said angle .gamma. being less than 90.degree.;
- and
- said input angle .beta. being no greater than 34.degree..
A disc chipper for chipping a long piece of wood, comprising:
- a disc rotating about a horizontal axis;
- an inclined chute for feeding the piece of wood to the disc;
- said chute arranged such that the piece of wood encounters the disc at an input angle .beta., which is the angle between the piece of wood and a line in a plane in which the disc is located, wherein said line passes through a point in the plane where said piece of wood contacts said disc and which extends tangentially in a direction in which the disc is moving at that point;
- said input angle .beta. includes an angle .omega., which is an angle between a projection of the piece of wood against the plane in which the disc is located and the horizon;
- said angle .omega. being less than 90.degree.;
- said input angle .notident. further includes an angle .gamma., which is an angle between a projection of the piece of wood against a floor surface and the plane of the disc;
- said angle .gamma. being less than 90.degree.;
- and
- said input angle .beta. being not greater than 34.degree..
