An apparatus for feeding one or more fibre threads, e.g. of glass, at an adjustable feeding rate. The apparatus comprises at least two synchronously driven feed rollers (11, 12) forming at least one nip for the fibre thread (10) and consisting of a first motor driven roller (11) and a second co-rotating roller (12). The motor driven roller (11) and/or the co-rotating roller (12) are/is provided with one or more, each in its respective peripheral slot (21) in the cylindrical mantle surface of the roller housed O-ring (22) of an elastic incompressible material, e.g. rubber. The O-ring bears on the peripheral surface of the adjacent roller (12) to transmit the rotary motion by means of friction.
