No-Twist Wire Rod Block mill is a single strand mill using cantilevered rolls of small diameter arranged alternatively 45 above and below the horizontal. The 90 relationship between adjacent rolls eliminates twisting oval into round passes as conventional oval-toround sequence, a factor which results in less guide wear and simpler guide design. The outstanding characteristic of the mill design is simplicity. A cluster of four precision helical gears is used to eliminate the need for mill couplings and spindles. This , before, not only enables smooth operation at all times, but also eliminates a constant source of vibration and gauge variation and reduces the overall maintenance required on the mill. Furthermore, the elimination of twist contributes significantly to improvement in rod tolerance and ease of operation. Symmetrical roll parting adjustment is provided by means of eccentric sleeves, which support the roll shafts and the work and drive side high-capacity sleeve bearings and are equipped with side arms fitted with swivel nuts and connected by an adjusting screw. The movement of the screw adjusts each roll symmetrically towards or away from the pass line and the adjusting screw itself is accessible no matter whether the cobble screen is in the open or closed position. The combination of symmetrical parting adjustment and 90 orientation of adjacent stands provides a truly straight and constant pass line
