<p>Disclosed is a cutting machine for trunk and residual wood for the direct production of a mass of chips free of splinters and low in fines. Cutting takes place within a cutting rotor equipped with a replaceable blade ring, which together with its housing may be moved back and forth in front of the outlet of a wood feed chute equipped with pressure elements. A compression chamber is located inside the blade ring, in which the wood to be cut intermittently abuts against a counter support. The compression chamber is equipped with additional pressure elements in order to hold the wood substantially still and without fluttering, until it is cut, without leaving a residue, even in the case of wood of large cutting width. The additional pressure elements act transversely to the counter support. A stationary, slightly raised entrance barrier is arranged directly in front of the compression chamber. To prevent residual sections from assuming positions detrimental to the cutting process, an axially displaceable guide plate is provided in the compression chamber and the pivot axles of the pressure elements are arranged so that their pressuring motion deviates only slightly from the circle of rotation of the blade ring.</p> |
