An installation intended to separate the components of a mixture containing fibers () and granules () is provided. The installation comprises a tribocharger () for conferring an electrostatic charge upon the components (), and at least one pair of electrodes () for generating a separating electric field that conveys the charged components, according to their polarity, up to collectors (). The tribocharger () has a containment grating () arranged so as to retain the components in the tribocharger () until the components () have reached a sufficient charge, then to allow the components, once charged, through into the gap (), from which point the components () reach their collector () under the effect of the separating electric field.

Installation intended to separate, in an electric field, the components of a mixture of fibres and granules using a tribocharger provided with a grating for the selective confinement of said components

An installation is provided that is intended to separate two families of components of a mixture placed in a receptacle. The installation is provided with a screen and comprises a first electrode, a second electrode, and a generator that generates, between the first and second electrodes, an agitating alternating electrical field. The alternating electrical field is capable of alternately projecting all or some of the components of the mixture that is present in the receptacle towards or against the first electrode and then towards or against the second electrode in order to generate mechanical impacts on the components that contribute to breaking down the mixture within the receptacle and in order to facilitate the passage of components belonging to the second family through the screen. The screen ensures components belonging to the first family are retained in the receptacle.

Apparatus for separating the components of a mixture of fibres and granules by beating the mixture by means of an alternating electric field

In an electric vulcanization process, open loop and closed loop control modes can be used for controlling a heater output.

Operation of a tire vulcanization system

In an electric vulcanization system, a temperature of a heating medium in a fluid-tight enclosure is detected and adjusted during a current curing cycle.

Regulating temperature during tire vulcanization

A mold for a tire is disclosed herein. The mold includes first and second shells mold-able to lateral sidewalls of the tire, and a plurality of sectors that are distributed in the circumferential direction and are mold-able to the tread of said tire. The sectors are radially movable between an open position and a closed position of the mold. The mold also comprises at least one spacing interposed between each sector and each shell in order to keep said sector and the shells spaced apart in the radial direction in the closed position of the mold, such that the shells and the sectors are in contact in the radial direction only by way of the spacing. The spacing is also able to limit the heat transfer between the shells and the sectors in said closed position.

Segmented mold for a tire and related molding method

A tire vulcanizing device includes a vulcanization mold and a central part. The vulcanizing mold includes molding parts that defining a curing chamber therebetween. Inside the curing chamber is arranged a heating and ventilation apparatus structured for use with a heat-transfer fluid. The central part is structured to collaborate with the vulcanization mold by providing support to a heat-transfer fluid inlet and establishing communication between the heat-transfer fluid inlet and the curing chamber. The central part includes heating elements that are configured to be brought into operation before the heating and ventilation apparatus is brought into operation to cure a tire using the heat-transfer fluid.

Device and method for vulcanizing tires

A mold for a tire comprises first and second shells that are intended to mold lateral sidewalk of the tire, a plurality of sectors that are distributed in the circumferential direction and are intended to mold a tread of said tire, a first and a second support plate that each comprise a bearing face with which the associated shell is mounted axially in contact, and a plurality of first and second heating means for heating at least the first and the second shell, respectively.
