  • Patent number: 5109687
    Abstract: In a roll type straightener, a barrel assembly including a pair of rolls (3, 3'), tightening male and female screws (5, 4), displacement male and female screws (14, 13) is mounted on a main shaft (8). The periphery of the respective female screws (4, 13) have a plurality of notches (22), with which pawls (18a, 19a) of levers (18, 19) are engageable for preventing the female screws (4, 13) from rotation with the main shaft (8) by a drive source. Upon the adjustment of barrel width, the pawl is selectively engaged with the notch (22) of the tightening female screw (4) or both female screws (4, 13), so that the female screws drive the mating male screws (5, 14) in the axial direction to displace one of the rolls (3') to a predetermined position, as the main shaft (8) rotates. The operation sequence is controlled in a fully automatic manner by a controller (23) while monitoring the rotation of the main shaft (8) by a detector (20).
