DEVICE FOR FORMING LAYER OF STEMS OF BAST-FIBRE CROPS Russian patent published in 2014 - IPC D01B1/16 

FIELD: agriculture.

SUBSTANCE: device for forming a layer of stems of bast-fibre crops comprises metering discs with the clutch, the feeding discs and a few pairs of thinning discs rotating at different speeds, the sensor of control of the layer parameters and the controller of change the modes of operation. According to the invention the sensor is located in front of the metering discs to control the angular disorientation of the stems, the clutch is controlled by the amount of torque on the shaft of the metering discs, and the controller is connected to the system of synchronous control of the ratio of rotational speed of the thinning discs and the torque on the shaft of the metering discs. The result of the claimed invention is to create a layer with the constant density and the lowest possible angular disorientation of stems, which a layer has before layer-forming machine regardless of existing change in this parameter.

EFFECT: use of this device for forming a layer of stems enables to increase its suitability to scutching due to reducing the angular disorientation that eventually can lead to an increase in yield of long fibre, the large capital investment is not required.
