A rotary race pulley matrix (16) and pad countermatrix (24) pipe bending machine, with the countermatrix (24) supported through a holder (24") therefor swinging in the lie of rotation of the matrix (16) on a support (20) in its turn pivoted (22) so as to swing in the lie of the matrix (16) on mounting means (11) that are stationary with respect to the machine body (11) during the bending operation. The oscillation of the countermatrix (24) and of its support (20) is restricted in the sense of feed of a pipe (p) by a pair of complementary ledges (26, 27) provided on the countermatrix holder (24") and on the support (20) and by a pair of complementary ledges (32, 25) provided on the support (20) and on the mounting means (24") therefor respectively, said ledges (26, 27; 32, 25) stopping the countermatrix (24) and the support (20) correspondingly to the working position of the countermatrix (24).
