Machine and method for filling containers

A machine for filling containers, each container having a longitudinal axis, the machine comprising:

• a conveying device;
• at least one handling unit configured to be fed by the conveying device along a transfer path, the at least one handling unit including a support device configured to receive and retain a container and at least one filling device selectively activated for feeding a pourable product into the container while the at least one handling unit travels along the transfer path;
• a pressurizing circuit selectively in communication with the container advancing along the transfer path to feed an operative fluid that is pressurized at a pressure higher than atmospheric pressure into the container;
• a decompression circuit selectively in communication with the container advancing along the transfer path to discharge excess pressure with respect to the atmospheric pressure, after completion of the filling of the container with the pourable product;
• at least one actuating device selectively switched to an active state to rotate the container about the longitudinal axis while the container is advanced along the transfer path;
• and
• a control unit configured to:
• control activation and deactivation of the at least one filling device and the at least one actuating device;
• control connection of the pressurization circuit and the decompression circuit with the container;
• and
• simultaneously maintain the at least one actuating device in an active state while the decompression circuit is in communication with the container so as to rotate the container about the longitudinal axis during decompression.
