Embodiment Construction

[0034] As can be seen in detail in FIGS. 1 and 2 , the cutting machine comprises a rotor 1 driven by a shaft 2 . The rotor 1 has a ring of blades 3 parallel to the axis. A knife cage (Messerkorb) with knives 4 also arranged parallel to the axis surrounds the rotor 1 . The rotor 1 and the cutter cage are installed in a casing 5 and are surrounded by the casing 5 together. The housing 5 has an inlet 6 for chips and an outlet for processed wood chips.

[0035] FIG. 2 schematically shows the rod-shaped raw material 20 in two positions. The raw material in this example is a regular rectangular block of wood. However, this raw material can also have other shapes, for example with irregular interfaces. The only point is that this raw material 20 is more or less rod-shaped, ie its longitudinal dimension is greater than its transverse dimension in a plane perpendicular thereto.

[0036] The raw material 20 is fed into the shaft-shaped feed port 6 as indicated by the arrow. It the...

Abstract

The invention relates to an intermediate product, a method for processing the intermediate product and a wood chipping device for processing the intermediate product. The intermediate product is substantially rod shaped and is sized in a range that includes between one and two times as oriented strand (OS) chips. The intermediate product is fed to a wood chipping device. The wood chipping device has a number of blades. The number of blades each have a number of cutting edges that run parallel to a blade ring axis, and which enclose a working chamber. The intermediate product is rotated about the blade ring axis and is aligned in such a way that it lies substantially parallel to the blade ring axis and is pressed by centrifugal force against the cutting edges.

Description

technical field [0001] The invention relates to a method and a device for producing sawdust from wood. There are in principle two systems in this respect, which differ fundamentally from each other and thus produce different products. Background technique [0002] The first system involves so-called direct cutting machines. In this, uncut logs are fed into a trough. A knife ring (Messerring) equipped with a plurality of knives on its circumference is arranged parallel to the main axis of the wood. These knives extend with their cutting edges tangential to the knife ring. The knife ring may travel such that the knives penetrate into the log stock to cut the log. See, for example, German patent specification DE 29 47 199 C1. [0003] Another direct cutting machine belonging to the first system described above has a rotatably supported disc. A cutting knife is mounted on one side of the disc. The logs or trunks are fed into the processing surface with their fibers parall...
