La paroi inférieure de chaque canal est percée d'un orifice à travers lequel un poinçon animé d'un mouvement vertical alternatif pousse une quantité de verre que l'on appelle «paraison» et qui correspond au poids de l'objet à fabriquer. - Une paire de ciseaux coupe automatiquement la queue de la paraison et celle-ci tombe dans un moule où elle prend sa forme définitive.  2, fiche 2, Français, - queue%20de%20paraison

... flash is a by-product of extrusion blow molding and it must be provided for in the design of the mold cavity tooling. Where the flash will exit from the cavity, clearance or a flash pocket is created. The depth of this flash pocket is critical, particularly with large-diameter, thin-walled parisons. If too deep, the flash will not be adequately cooled and this may cause trimming problems. If too shallow, the flash will hold open the mold, creating a thick pinch-off that may also cause trimming problems. Dividing the cavity from the flash pocket is the pinch-off.  1, fiche 3, Anglais, - flash%20pocket

The pinch-off areas pinch the ends of the plastic parison and seal the edges together when the mold closes. These surfaces are subject to more wear than any other part of the mold....

Dividing the cavity from the flash pocket is the pinch-off. The pinch-off has a dual role : it must seal the open ends of the parison and, at the same time, cut the flash from the bottle.  2, fiche 4, Anglais, - pinch%2Doff%20area

On bottles with handles, the flash is most often removed in a downstream trim press. In this press, the bottle is held in a contoured nest where a punch, also countered, knocks off the tail, handle, and top flash. The flash cut from the bottle by the mold pinch-off is held in place by a very thin membrane.  5, fiche 5, Anglais, - flash%20trimmer

Another process somewhat related to extrusion blow molding is the extrusion/molded neck process. Still used today by Owens-Illinois, this is a proprietary process that traces its roots to glass-blowing technology. It is unique in that the bottle neck finish is injection molded and the bottle body is extrusion blow-molded. In this process, the two halves of a neck finish cavity or neckring are mounted to an actuating head assembly, which intermeshes with the two halves of the blow-mold cavity. The process cycle begins with the main body mold cavity open and the neckring cavity closed. The actuating head assembly moves downward to contact the extrusion die head. When it is in position, extrusion pressure fills the neck section with plastic melt. After it is held for one to two seconds, the head assembly moves upward while, simultaneously, the parison is extruded. When the head assembly reaches the top of its stroke, the blow-mold cavity closes on the parison. The remaining steps of parison pinch-off, blowing, and part removal all follow conventional techniques. Although the production cycle is somewhat slow, the process offers the quality advantage of an accurately molded neck and the process advantage of a parison held at both ends.  1, fiche 6, Anglais, - extrusion%20molded%20neck%20blow%2Dmolding%20process
