METHOD OF STRAIGHTENING UNTWISTED FIBRE AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC D02J1/18 

FIELD: textiles, paper.

SUBSTANCE: untwisted fibre is continuously moved with controlled tension over the opening of the air path, and it is exposed to the air flow formed by the air supply under pressure in the air duct opening to form a bend of untwisted fibre in the said opening, and the air flow is formed in such a way that its main central part is directed perpendicular to the plane of movement of the untwisted fibre, and the side parts of the air flow generated by the edges of the untwisted fibre along the axis of its movement, changing its direction relative to the main central part of the air flow, are deflected towards the sides from the axis of movement of the untwisted fibre. This method can be implemented at the plant for straightening the untwisted fibre, which comprises pads to form the air flow.

EFFECT: method and plant for straightening the carbon yarn enable to distribute evenly the carbon yarn threads and to form a uniform in width tape of required width of high quality due to changing the direction of the intake air flow.
