<p>(57) Method for closing the gate of a rotary barking drum intended for barking of wood, and the gate of a barking drum. The gate is rotated so that it is shifted so as to close the discharge opening at the end of the barking drum partly or completely. During the closing movement, the centre of the movement of rotation of the gate (1) is shifted and approaches the centre of the cross-section of the drum. For the control of the closing movement, the gate is provided with two support members (2, 3), which can be displaced in a plane parallel to the gate along one common guide (4, 5) or along two separate guides. At least a part of the guide (4, 5) or guides is curved in the same direction as the mantle of the barking drum is curved. The curve radius of the guide (4) intended for the support member (2) of the gate that runs as the first support member during a closing movement is shorter than the curve radius of the guide (5) intended for the support member (3) of the gate that runs as the rearmost support member during a closing movement.
