Abstract: Procedure and apparatus for controlling the barking process in a barking drum, which procedure uses measuring devices (13a,13b,14a,14b) placed in conjunction with the barking drum (1) to measure the weight of the drum. The measurement signals obtained from the weight measuring devices are used to calculate the degree of fullness of the drum, and this data is used to control the position of the delivery gate of the drum so as to achieve the desired degree of fullness. Moreover, the degree of barking of the logs is monitored, and the barking degree data is used as a basis for the control of the speed of rotation of the drum.
