Patent ID: 8302373

Claim:
A method for producing a bundle of filaments from a plurality of filaments, the method comprising: releasing the plurality of filaments from a creel part consisting of a plurality of creels ( 1 ), wherein each of the creels ( 1 ) has a bobbin ( 2 ) wound with each of the filaments and rotates by a rotational axis; winding the plurality of filaments together around multiple driver rollers ( 3 a ), ( 3 b ) and ( 3 c ), sequentially to give an assembly of the plurality of filaments which are assembled without a twist; and winding the assembled filaments around a winder ( 5 ) to produce the bundle of filaments, wherein each of the creels ( 1 ) is equipped with a tension controller ( 6 ) for regulating a rotational speed of the each of the creels to maintain the tension of the filaments released from the bobbin ( 2 ) and wounded around the driver roller ( 3 a ) constant, and wherein the tension controller ( 6 ) is a mechanical tension controller which is operated by a process comprising: sensing a tension of the filament when it is released from the bobbin ( 2 ) by means of a lever type device ( 6 a ) which senses the tension of the filament; and transferring the detected tension through a tension transfer device ( 6 b ) in a belt form to a brake ( 6 c ) for regulating a rotational speed of the bobbin ( 2 ) that rotates under the tension of the filament.
