FIELD: feed of one or several fibres, for example glass fibres. SUBSTANCE: includes at least two rollers set in motion in synchronism; these rollers form at least one clamp for fibre. First roller is set in motion by motor and second roller rotates together with it. First and/or second roller rotating together with it is provided with O-shaped rings made from elastic incompressible material, for example, rubber; each ring is placed in respective peripheral groove available in cylindrical surface of roller. O-shaped ring rests on peripheral surface of adjacent roller for transmission of rotary motion by means of friction. EFFECT: protection of environment against dust; reduced mass of device. 3 cl, 2 dwg
