Abstract

PURPOSE:The titled three-roll apparatus, capable of improving the efficiency of the roving step and increasing the draft ratio, and comprising a nipping means at the tip of an apron and the first fluid injection nozzle and the second injection nozzle between front rollers and take-up rollers. CONSTITUTION:The tips of an upper and a lower aprons 3a and 3b are always nipped by a tenser bar 15 of T-shaped cross section provided at the tip of the lower apron 3b of middle rollers 4 and a cradle 17 provided at the tip of the upper apron 3a. Thus, the draft unevenness is suppressed, and control force of the fiber is increased to form a regularly oriented fiber layer. A stable extending triangular part formed at the delivery part of front rollers 5 provides an increase in the open end ratio of the fiber, and the first fluid injection nozzle and the second injection nozzle provided between the front rollers 5 and take-up rollers function effectively.
