Abstract
A roving frame for producing large-diameter and small-diameter roving bobbins has two rows of work stations with the work stations lying at vertices of a triangle for the production of small-diameter bobbins, flyers of a small span are provided for each of the spindles at each of the work stations whereas these flyers are replaced by large-span flyers which are located at every second work station. The triangle base has a length L which is just slightly greater than the diameter of the flyer in the case of the small diameter bobbins whereas the triangle side lengths are substantially equal to the diameter of the large-span bobbins.
