A method and apparatus for intertwisting lengths of relatively stiff, deformable monofilament or multifilament material to form a stranded segment, such as to form the intertwisted ends or legs of a wire bundle comprising a portion of the bristles of a wire brush. The twisting is accomplished by gripping each length to be twisted at one end in a stationary gripping mechanism and slidably holding the lengths in a rotatable twisting head that locates the respective portions of the lengths that are held thereby in fixed relation to one another and symmetrically spaced about the axis of rotation of the twisting head. The twisting head is initially moved axially to a predetermined axial spacing from the gripping mechanism and when the desired spacing is achieved the twisting head is rotated through a predetermined angle to intertwist the lengths. When the rotation is stopped the steps are then repeated sequentially until the lengths are intertwisted a desired number of helical convolutions.
