Abstract: A production method for blowing a container starting from a parison comprising the steps of: i) positioning a parison inside a forming mould (2) for forming the container; ii) deforming the parison (10) placed in the mould (2); the step of deforming the parison (10) comprising the sub-steps of: introducing a pressurised fluid into the parison (10) placed in the mould (2); sucking gas which is located inside the mould (2) and outside the parison (10) present in the mould (2).

Abstract: A system for producing plastic containers from preforms, comprising: a plurality of blowing stations comprising at least a first and a second blowing station (31, 32) for blowing the preforms; a movement system (2) for moving the preforms comprising a delivery line (21) for delivering the preforms towards said blowing stations. The delivery line (21) comprises a first and a second outlet zone (211, 212) of the preforms from said delivery line (21). The first and the second outlet zone (211, 212) for the outlet of the preforms are in mutually distinct positions and are intended to supply the first blowing station (31) and the second blowing station (32), respectively.

Abstract: A rotary seamer (1) is provided with a carousel (2) and with at least one seaming station (3) associated with the carousel (2) and comprising a rod-like element (6) rotating around its own longitudinal axis, a seaming tool (4) rotatably connected to a lever (5) integral with the rod-like element (6) and means for rotating the rod-like element (6) around its own longitudinal axis, in such a way as to displace the seaming tool (4) from an operative position, in which it interacts with an object seaming it, to a deactivated position, of non interference with the object; said means comprising an electric motor (7) associated with the carousel and kinetically to the rod-like element (6) and control means operatively active on the electric motor (7) to rotate the rod-like element (6) according to a predefined logic. In known seamers the actuation of the seaming tool is achieved by means of a cam, this entailing limitations and drawbacks in the adaptation of the seamer to the treatment of different objects.

Abstract: A rotary seamer (1) is provided with a carrousel (2) and with at least one seaming station (3) associated with the carrousel (2) and comprising a rod-like element (6) rotating around its own longitudinal axis, a seaming tool (4) rotatably connected to a lever (5) integral with the rod-like element (6) and means for rotating the rod-like element (6) around its own longitudinal axis, in such a way as to displace the seaming tool (4) from an operative position, in which it interacts with an object seaming it, to a deactivated position, of non interference with the object, an electric actuator (11) associated with the carrousel (2) and means for connecting said electric actuator (11) to the seaming tool (4), to rotate it around its own longitudinal axis. In known seamers, the seaming tool is mounted idle on the lever, this entailing limitations and drawbacks with regard to the hygiene and reliability of the seamer.
