Abstract
893,451. Curving. BOLDRINI, S.A. Dec. 9, 1958, No. 39655/58. Class 83 (4). [Also in Group XXVIII] Means for disengaging the bearing from one end of a bending roll, to allow the removal of sheet bent around the roll, includes a two-armed lever, one end of which carries the bearing and the other end is acted upon by means which cause the lever to pivot about an axis at right angles to the roll axis and below the end of the roll to be freed to swing the bearing away from the end of the roll. Metal or plastic sheet is bent around a roll 1 supported at one end in a bearing 30, rockable at 32, and at the other end in a bearing 3 carried by an arm 7 of a lever, pivoted at 19, whose other arm 20 is connected by a rod 22 to a piston 23 in an hydraulic cylinder 13 pivoted to the machine frame at 18. The bearing 3 is formed with interior surfaces having a centre of curvature at the axis of the pivot 19. A plain bearing 2, in which the roll journal is rotatable, is positioned by the arm 7 and a plate 5 on the roll end and has its upper surface curved about a centre at the axis of the pivot 19. In operation, to free the end of the roll 1, a pump 17 is actuated to move the piston 23 and rock the lever 7 first to swing the bearing 3 off the end of the roll 1 and then through a rod 10 and bell-crank 34 to lower a bearing 29, supporting an extension 1a of the other end of the roll, to rock the roll about the pivot 32.
