An extrusion blow mold machine forming hollow containers. The machine has at least one pair of opposing half molds that combine to form a mold and define a mold cavity. Each of the half molds is positioned on a carrier plate and includes first, second, and third mold segments. The first and third mold segments can move with respect to each other and with respect to the second, fixed mold segment. A mechanical structure creates vertical movement of the first and third mold segments relative to the second mold segment as the mold opens horizontally, without the aid of any electrical, hydraulic, or pneumatic device. A closing unit engages the carrier plate to move the carrier plate and its respective half mold toward and away from the opposing half mold and its respective carrier plate, thereby closing and opening the mold.

An apparatus for heating plastic preforms includes a first transport device that transports the plastic preforms in a separated manner, wherein said first transport device has a plurality of recesses for receiving the plastic preforms, and a second transport device that takes over the plastic preforms transported by the first transport device and transports said plastic preforms along a predetermined transport path. The second transport device has a plurality of holding elements for holding the plastic preforms. The apparatus also includes at least one heating device that heats the plastic preforms transported by the second transport device, wherein at least the first transport device is a circulating transport device, wherein a relative position of the recesses of the first transport device in the circulation direction of the first transport device relative to a position of the holding elements in respect of the transport path can be changed.
