Abstract: A blow-molding or stretch-blow molding plant for making containers from thermoplastic polymer blanks, in particular PET, including a blowing bell-nozzle for blowing a pressurized fluid into a blank arranged in a cavity of a mold, the nozzle having one end adapted to be sealingly supported in front against a support plate provided in one surface of the mold capping the neck of the blank; the support plate is ring-shaped having an outline of similar shape as that of the outline of the end of the nozzle, the ring being engaged in a gutter which is hollowed out in the surface of the mold and which surrounds spaced apart the opening through which the neck of the blank passes.

Abstract: The invention relates to a molding device for blowing thermoplastic recipients of various heights, said device comprising a mould provided with two mould halves and a mould bottom which are mutually mobile. Each mould half comprises a mould carrier, a chill carrier and a chill, said two chills and the mould bottom comprising mould impressions, which together define a molding cavity. The inventive device also comprises means for compensating the blowing pressure, said means being provided between a mould carrier and the associated chill carrier. For recipients with the maximum height, the chill carriers and chills are the same height. For lower recipients, the chills are lower than the chill carriers and radially reinforcing means are provided on the internal faces of the carriers in the parts thereof which do not co-operate with the chills.

Abstract: The invention concerns a molding device for making by blow molding or stretch blow molding thermoplastic containers capable of having different heights, comprising a module (1) with two mutually mobile half-molds (2A, 2B) and an axially mobile mold base (5); the mold base is supported by a support (22) with which are associated in operation means for axial displacement; the mold base, and its support (22) are secured by spacing means (24) with adjustable variable heights relative to the height of the molding cavity and provided in the form of threaded means with reverse-pitch double threading; the mold base can thus be positioned axially relative to the height of the molding cavity without modifying the support (22) and/or the displacement means which are operatively associated with it.
