Abstract
A rotary machine for producing recipients made of a thermoplastic material by drawing and blowing performs by a molding device which is provided with an openable mold and a movable drawing rod, a device for supporting and driving the drawing rod, which is embodied in such a way that it is mechanical and includes a power take-off device for generating, on the basis of a monodirectional rotary rotation, two rotary motions of given angular amplitudes of a rocker in two predetermined angular places of a merry-go-round path and a device for converting the two rotary movements of the rocker into two opposite linear alternately descending and ascending displacements of a drive unit connected to the drawing rod.
