Apparatus for cross-cutting treetrunks, comprising a device for measuring lengths |
摘要 |
An apparatus for cross-cutting a treetrunk comprises gripping members which embrace the treetrunk, a feeding mechanism for moving the treetrunk in its longitudinal direction, and a saw which moves transversely to the longitudinal direction and cuts the treetrunk into predetermined lengths. One of the gripping members includes a rotatable guide roller having peripherally spaced apart teeth which engage the treetrunk. The apparatus also comprises a displacement pickup unit which ensures that the treetrunk is cut to a predetermined length. The displacement pickup unit is connected to the guide roller and detects the number of rotations of the guide roller, thereby detecting the longitudinal displacement of the treetrunk. The displacement pickup unit is located within the gripping member so that it is shielded from outside influences.
