Abstract
A blow-molding installation for manufacturing receptacles from blanks of thermoplastic polymer, said installation comprising a bell-nozzle for blowing a fluid under pressure into a blank () disposed in a cavity () of a mold (), the end of the nozzle being in the shape of a bell () which is suitable, during blow-molding, for being pressed into leaktight end-to-end abutment against a wall (F) of the mold while capping the neck () of the blank that emerges from said wall; said installation further comprises means () for securing the nozzle to the wall of the mold by mutual attraction, which means can be activated, after the nozzle has been brought into end-to-end contact with the wall (F) of the mold without flattening a sealing gasket (), so as to attract the nozzle () and the wall (F) towards each other with an attraction force greater than the repulsion force due to the pressure of the blow-molding fluid.
