摘要:
Process and device for treating vulcanized rubber surfaces before bonding by creating surface roughness and elimination of degraded surface particles through the use of a high-pressure fluid jet.
摘要:
A metering device which includes a storage reservoir 3, a volumetric extror 30 introducing roughly gauged batches of material into an intermediate hopper 4, which empties periodically into a weighing hopper 1. Under the latter, rapid stabilization scales 2 record the weight of the batch contained in the weighing hopper 1. The latter is emptied onto a belt 5 at the end of a time interval proportional to the weight of the batch or of one of the preceding batches.
摘要:
Aqueous composition intended to form an antimigration and antiozone protective coating on the external surface of a tire, comprising an aqueous emulsion of at least: (a) a polymer called constituent I, said constituent I being a homopolymer or copolymer based on at least one monomer chosen from the group of acrylic, methacrylic and vinyl esters and having a glass transition temperature below 0.degree. C.; and (b) a constituent II chosen from the group consisting of a hydrophilic silica and a homopolymer or copolymer based on at least one monomer chosen from the group of acrylic, methacrylic and vinyl monomers, said homopolymer or copolymer having a glass transition temperature above 25.degree. C.

摘要:
Prevulcanized tread strip (1, 10) including a cap (2) and two side wings 20, 30), such that each lateral end of said wings (3, 20, 30) ends in a bead (4, 21, 31) made of elastomeric material with a substantial thickness in the region intended for connection to a tire carcass.
摘要:
The object of the present invention is a rubber composition which is inted for the manufacture of tires and has a base of precipitated silicas "doped" with aluminum, the aluminum content being between .gtoreq.0.35% and .ltoreq.3% by weight of silica. Said composition has improved working properties as well as improved hysteresis properties.
摘要:
A method of fitting a tire and support ring on a one-piece wheel rim in wh the rim includes a first wheel rim seating surface and a second wheel rim seating surface, the first wheel rim seating surface tapering outwardly and having a small hump at the axially outer end and being connected axially on the inside to a cylindrical portion intended to receive a tread support ring, the tire having a first bead and a second bead to be fitted, respectively, on the first wheel rim seating surface and the second wheel rim seating surface, and in which the removable support ring is inserted into the tire before fitting the support ring on the wheel rim.
摘要:
An integral rim intended for mounting a tire having at least two beads and including, when viewed in meridian section, at least a first rim seat, a second rim seat, and a rim base which is without a groove. The first rim seat slopes downwardly towards the outside. The second rim seat has a generatrix, the axially inner end of which is on a circle of diameter at least as great as the diameter of the circle on which the axially inner end of the first rim seat is located. The assembly formed by such a rim and a supporting ring for the thread.
