摘要
A matrix and countermatrix type bending machine for right- and left-hand bending an elongated piece (P) comprises a roller-shaped matrix (1) provided with a partial circumferential groove (2) that is interrupted at its two ends, the matrix (1) being driven by the shaft (0) of a motor, and a pair of countermatrices (25, 26) being carried by respective countermatrix support members (19, 20) pivoted on a turret (11) that is rotatable mounted on a slide (8) in a given arc of rotation about its axis perpendicular to the slide (8) by a lever (12). The matrix (1) has an elongated piece retaining means (3, 4). The first or the second countermatrix (25, 26) are selectable to co-operate with the matrix (1) in bending said elongated piece (P) depending on the required curvature to right hand or left hand.
