ABSTRACT OF THE DISCLOSURE The invention relates to a device for laying and preforming a section of web in a forming mould which is provided at a container thermoforming station. The shaping member is mounted to move between, on the one hand, a lower position corresponding either to the position of obturation of the bottom opening in the forming chamber when the moulding unit occupies its thermoforming position, or to the median zone of the forming chamber when said unit occupies the stripping position and, on the other hand, an upper position corresponding to the median zone of said forming chamber when the moulding unit occupies the thermoforming position. An annular slot is defined between the lateral face of the shaping member and certain corresponding parts of the lateral face of the forming chamber in the median zone thereof. A transfer piston is adapted to penetrate in the forming chamber.
