    摘要: A method of manufacturing a container from a blank in a stretch blowing assembly equipped with a mold provided with a wall and a mold bottom axially movable between an extended position and a retracted position and a stretch unit having a rod axially movable with respect to the wall and a device for controlling the movement of the rod. The method involves a stretch blowing phase; a boxing phase during which the mold bottom, initially in the extended position, is moved towards its retracted position, the boxing phase having a retraction operation including controlling a movement of the rod in synchronization with the movement of the mold bottom, or releasing the rod to allow the free axial movement thereof.
