    Abstract: A rotary apparatus for hydraulic forming of shaped containers including a rotatable forming wheel having a central axis of rotation and a plane of rotation perpendicular to the axis of rotation. A plurality of forming stations is supported by the forming wheel. The forming stations are operable to expand a preform into a shaped container by forcing a liquid into the preform. The longitudinal axis of each forming station forms an angle with the plane of rotation of the forming wheel of less than 20° while the preform is being expanded. The projection of the longitudinal axis of each forming stations onto the plane of rotation of the forming wheel forms an angle with the radial direction at the position of the forming station of less than 20° while the preform is being expanded.

    Abstract: A machine and method for forming containers from preforms. The machine includes a mold loading station for loading successive preforms into successive molds, each mold forming a mold cavity having the shape of the container to be produced. The machine also including a forming station for forming the containers by injecting a gaseous or liquid fluid into the preform contained in each mold in order to expand the preform such that each preform acquires the shape of the container defined by the mold cavity. In the machine, the mold loading station and the forming station are distinct from each other, and the machine further includes a transferring station arranged between the mold loading station and the forming station for transferring the successive molds containing the preforms from the mold loading station to the forming station.

    Abstract: A method for manufacturing plastic containers in which, for each container, a plastic preform containing air is supplied; the preform is heated at a preform temperature over the glass temperature of the preform material, the preform is inserted in a mold having a mold cavity; and the preform is expanded to a container having the shape of a mold cavity by a forming liquid. The method also includes, between steps (b) and (d), the injecting of a gaseous product into the preform containing air, wherein the gaseous product is absorbable by the forming liquid. The injection conditions of the gaseous product are selected such that the injected gaseous product expels the air out of the preform.
