Rubber-cord casings assembly method

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of rubber-cord casings, namely to methods of balloon type rubber-cord casings with clincher beads assembly. According to method, forming rubber-cord casing, uniformly stretching casing edges, seating bead rings, forming rubber-cord casing beads. Rubber-cord casing edges are uniformly stretched in cone-shaped manner. In side zones on evenly stretched casing cone-shaped edges outer diameter non-stretchable belt material is wound layer-by-layer, thereby forming bead rings. Non-stretchable belt material layers are duplicated. Wrapping casing edges onto bead rings. Non-stretchable belt material is made in form of rubber-cord belt with number of threads in row from 3 to 12 threads.

EFFECT: technical result of disclosed technical solution is creation of rubber-cord casings assembly method, increasing range of produced balloon type rubber-cord casings with clincher beads.

FIELD: metallurgy.

SUBSTANCE: cast article representing an optical data storage of light dissipating glass comprises polycarbonate produced in interaction between, at least, one bisphenol and phosgene at phase interface. Surplus phosgene is used in amount of 8-17% per the sum of used bisphenols. Integrated intensity of electric field measured at 100 mm from cast articles produced during 5 minutes of continuous casting at pressure varied from -30 to 0 kV/m, preferably, from -20 to 0 kV/m.

EFFECT: lower intensity of electrostatic field on cast article surface, higher quality of cast articles.
