Abstract

A machine for producing ampoules with a check-value from synthetic thermoplastic film has the moving film supported on a conveyor belt which for a brief period acts as a base while the seam welders turning on their rotor, press the layers of film to give a consistent weld around the circumference of the ampoules, before passing them to the separator.
