An apparatus for manufacturing a three-dimensioned crimp filament comprising: a drive means for pulling filaments; a group of guide rollers arranged in a reverse U-shaped roller group, said roller group being provided ahead of said drive means and adapted to be rotated about a longitudinal axis such as to give forward and rearward portions of a plurality of filaments while stretched with a single twist formed thereon and being transferred by said drive means mutually opposite twisting actions; a pair of rotative rollers each provided with a groove, said roller pair being provided immediately after the roller at the forward end in said roller group and provided with a non-slip means for pulling the single twisted forward portion of said filaments at a transfer speed such that the filaments of said forward portion form into a double twist and are cooled sufficiently to effect a thermal set; a heating means provided ahead of said roller group and serving to heat the filaments formed with a double twist; a single twist transfer roller group provided ahead of said heating means and consisting of a plurality of rollers and given a predetermined rotational tension for guiding filaments formed with a single twist; and a means for stopping spread of double twist, said stopping means being provided on the last roller in said roller group. |
