    Abstract: The invention provides processes and apparatus for removing bark from logs. The logs are subjected to mechanically applied compression forces acting against the sides of the logs, these forces being such as to expel juices from the ends of the logs. The pressure on a log is preferably between 500 and 3,000 p.s.i. per square inch measured on the area of the diametrical plane of the log. This compression provides loosening the bark which can then be readily removed. Preferably, a stack of logs is simultaneously compressed by means of a hydraulic press, and the juices which are expelled from the ends of the log are collected for sale as a by-product. The loosened bark on the log is then removed by a mechanical frictional treatment.

    Abstract: An apparatus for debarking logs has a plurality of longitudinally spaced frames each of which carries a pair of horizontally and transversely spaced upper wheels and at least one lower wheel below and between the upper wheels. At least one conveyor element is spanned over the wheels in each frame and has a pair of inner stretches defining a V in line with the inner stretches of the other frame and forming therewith a log-receiving cradle. At least one of the wheels, preferably the lower wheel is driven, and it is possible either to tip the frames so as to unload the logs or to cant them about vertical axes relative to the longitudinal direction of the logs so as to move the log along the apparatus.

    Abstract: Method and device for delimbing a tree trunk (60) in a compliant gripping state defined by a set of limbing knives (18, 24, 26, 28) enclosing the trunk. The limbing knives are repeatedly adjusted through a control unit (46) for adaption of the gripping state to a varying thickness of the trunk when the trunk is advanced between the knives for the delimbing of the trunk. The invention comprises entering a desired compliance (D1) of the gripping state in the control unit (46), detecting an actual compliance (d) of the gripping state, and performing each adjustment of the limbing knives via the control unit until the actual compliance (d) corresponds to the desired compliance (D1).

    Abstract translation: 用于将树干（60）分离成由包围树干的一组枝状刀（18,24,26,28）限定的柔顺夹持状态的方法和装置。 通过控制单元（46）重复地调节绞刀，以便当行李箱在行李箱之间进行分离时，将夹紧状态适应于树干的变化厚度。 本发明包括在控制单元（46）中输入所要求的夹紧状态（D1），检测夹紧状态的实际顺从性（d），以及经由控制单元执行各种调节刀具直到实际符合 （d）对应于期望的依从性（D1）。
