A stretch blow-moulding machine is presented, with a central vertical axis of rotation (1), a rotary distributor (2) for compressed air and power, arranged in the region of the axis of rotation (1), blow-moulding stations (3), arranged radially around the axis of rotation (1) and each having at least one mould body (4) for receiving bottle preforms, a blowing cylinder (5), arranged displaceably with respect to the mould body (4), valves for regulating the supply and removal of compressed air, arranged on the blowing cylinder (5), and lines for connecting the blowing cylinder (5) to the rotarydistributor (2). In this case, the longitudinal axes (A) of the blowing cylinders (5) are arranged parallel to the axis of rotation (1) and the direction of displacement or direction of stroke (H) ofeach blowing cylinder (5) in relation to the assigned mould body (4) likewise respectively comes to lie parallel to the axis of rotation (1). Furthermore, the valves are arranged in a single blowing block (7), which is arranged laterally on the blowing cylinder (5), tangentially with respect to the axis of rotation (1).
