Abstract:
A chuck for actuating plastic material containers, in particular performs, along a conveying line, includes a structure, fixable to a link of a conveying chain, a body, defining a longitudinal axis, inserted into a longitudinal through-hole of the structure and adapted to axially slide and/or rotate about the longitudinal axis, provided with gripping means at a first end for gripping a container neck. The structure is provided with locking elements for locking the body in a predetermined angular position, with the body being provided with at least one indication element of the predetermined angular position.
Abstract:
Heating device for preforms, capable of accurate and highly localised heating of the preforms before the blow moulding step of the process of producing bottles or containers from plastic materials. This device comprises two or more heating modules (11-16), each comprising a through opening (100) in the direction of the thickness of the heating module and a heating element (5) positioned in the vicinity of the through opening. The modules (11-16) are assembled such that the through openings (100) are aligned reciprocally with each other to define a conditioning cavity for the heating device (1). Each heating module (11-16) comprises induction means (2).
Abstract:
A method for recycling energy and related blow molding machine—for blow molding plastic material containers including a recycling system for recycling the pneumatic energy of the discharge air coming from the blowing cavities of said machine, capable of recycling the discharge air making it available at a given pressure for a subsequent blowing in a cavity.
Abstract:
A process and device for drying the coating of containers made of thermoplastic material. The process involves feeding said containers through a furnace divided into two areas: in the first, most of the solvent of the coating is removed by heating the paint with infrared lamps, while the temperature of the containers is controlled through an airflow; in the second, the remaining solvent is removed using said airflow coming from the first area of the furnace.

Abstract:
A heated blow mold for the thermostabilizing treatment, or the heat-set process, where at least a heating system is housed between the mold (2) and mold holder (3). Said system consists of a set of tubular electric resistors, which are parallel to the generator of the mold and of the item to be molded, connected to each other by additional electric resistors, which are basically transversal in relation to the first resistors and placed in areas requiring greater heat.

Abstract:
An injection nozzle plugging rod (4) of machines for moulding plastic material containers, provided with a locking system suitable for preventing the separation of the parts forming the actuating pneumatic piston of the same rod, said piston being subjected to considerable stresses during the machine operation. Thus, the rod according to the invention is able to prevent the piston binding, and therefore also the locking of the same rod, considerably reducing the number of maintenance interventions and thus increasing the throughput of the moulding machine.
Abstract:
A coating system (1) for blown containers (9) made of plastic material, with high production rate and flexibility so as to allow an efficient coupling with the most advanced one-stage or blowing machines. Such coating system (1), despite its high production rate, envisages a compact global structure with low implementation costs and contained energy consumption. Along with the system, a corresponding coating process is described, which consists in the effective and rapid application of several paint layers on plastic containers (9).
Abstract:
A compression-moulding press for moulding plastic containers (P) consisting of a moulding cavity formed by a plunger (5), a female mould (14), and two separable lips (7, 8). A cylinder (16) slides inside a sliding slide (22) to keep the lips (7, 8) closed. The plunger (5) slides inside the cylinder (16), with respect to both the cylinder (16) and the slide (22), when moulding the containers (P). Finally, a method for making plastic containers by means of compression moulding using said device is also described.
