BARK-STRIPPING DEVICE Russian patent published in 2008 - IPC B27L1/02 

FIELD: construction.

SUBSTANCE: bark-stripping device consists of a row of rotating bark-stripping axles, parallel to the direction of movement of logs, transported through them, which are made with a row of teeth, passing beyond the peripheral surface of the axle. The bark-stripping axles are arranged such that, processed logs rotate and forced into the upper position in turns under the effect of the rotation of the bark-stripping axles. From this upper position, the logs roll down to the lower position over other logs. At least the highest bark-stripping axle is displaced in the direction of the inner part of the bark-stripping device with provision for dynamic interaction with logs, colliding with them and moved by the bark-stripping axles, located in the lower position, for which the direction of motion of the logs will change such that, when the movement is split into horizontal and vertical components, the horizontal component will be directed to the inner part of the bark-stripping device. The higher the position of the bark-stripping axle, the higher the circumferential speed is chosen to be.

EFFECT: prevention of lodging of logs between bark-stripping axles and sidewalls of bark-stripping device and between bark-stripping axles.
