  • Publication number: 20230330895
    Abstract: A production line (100) has an internal mixer (MI); at least one hot mixing line (102) disposed downstream of the internal mixer and including at least one twin-screw mixing machine (BXc) that performs a process of mixing the rubber mixture exiting the internal mixer; at least one cold mixing line (104) disposed downstream of the hot mixing line and including at least one twin-screw mixing machine (BXF) that performs a process of mixing the rubber mixture exiting the hot mixing line; a batch-off installation (BO) disposed downstream of the cold mixing line that performs an anti-sticking and cooling process of the rubber mixture exiting the cold mixing line; and an end-of-line installation (FL) disposed downstream of the batch-off installation that performs one or more end-of-line processes of the rubber mixture.

  • Publication number: 20230226722
    Abstract: A production line (200) for performing multi-pass mixing sequences of rubber mixtures has at least one first mixing line (200A) that produces a masterbatch and at least one second line (200B) that performs a final mixing process during a final pass of a multi-pass rubber mixing sequence. A mixing process produces a variety of rubber mixtures in a production line of the type disclosed.

  • Publication number: 20220161457
    Abstract: A mixing and cooling system (1) includes a mixing and screw-extrusion machine (10) with a mixer (12) having a converging conical twin screw; a ram (30) that moves along the inside of an introduction hopper (24) of the machine; a roller nose system disposed just downstream of an outlet (25) of the mixer to form a sheet (112) of the mixture exiting the mixer; and a mobile sleeve or sleeves (34) that move in a linear movement relative to the outlet. The system also includes a cooling system with a spray installation(s) (102, 104) that delivers water at a predetermined rate to the sheet exiting the machine; a suction installation(s) proportionate to each spray installation; and at least one transport means (114, 116) that transports the sheet in a predetermined direction.

  • Patent number: 10189313
    Abstract: Tire comprising a tread (40) extending between an outboard axial edge (45) and an inboard axial edge (46), over a width L, in which the tread comprises at least 4 circumferential ribs (411-414) separated by grooves (421-423), in which the circumferential rib (411) adjacent to the outboard axial edge of the tread extends from the outboard axial edge over a width of at least 0.6·L and comprises a portion (411a) with a width of at least 0.1·L made from a first rubber composition and an axially adjacent second portion (411b) made from a second rubber composition, the first rubber composition having values for the elastic modulus at 300% deformation, the Shore A hardness and the complex modulus G* at 60° C. which are respectively comprised between 1.1 and 2.1 times, 0.95 times and 1.20 times, and 1.00 times and 2.10 times the corresponding values of the second rubber composition.
