Apparatus for producing a filament interlaced yarn comprises a cylindrical roller mounted for rotation on an axis extending at an angle to its longitudinal central axis. The yarn is pulled over the roller at right angles to the axis of rotation and rotation of the roller causes the yarn to roll back and forth across the face of the roller. The rolling of the yarn produces alternately S and Z twist which causes the filaments to become interlaced or tangled to a degree that the yarn can be used in ordinary textile operations without further twisting.
