Abstract: An apparatus includes a first operating machine arranged for processing objects, a second operating machine positioned downstream of the first operating machine and arranged for further processing the objects, an accumulating arrangement interposed between the first operating machine and the second operating machine and arranged for receiving the objects, and a command and control arrangement arranged for detecting a parameter indicating the quantity of the objects contained in the accumulating arrangement and regulating the operation of the second operating machine on the basis of the parameter. A method includes dispensing synthetic plastics in a pasty state, compression-moulding the plastics to obtain a perform, blowing the perform to obtain a container, and filling the container with a product. Each step maintains its own regulated temperature so that the dispensing temperature is greater than the blowing temperature and the blowing temperature is greater than the filling temperature.
