| 20090025857 | Method And Machine For Rubberizing An Annular Surface Of A Body - Method and machine for rubberizing an annular surface of a body, the rubberized coating being applied by bringing said annular surface into rotation about an axis and progressively coating the annular surface itself by means of a strip, of a determined section, of elastomeric material supplied by an extruder, shaped by at least one calender and applied, at a determined application speed, to the annular surface to be rubberized by an applicator roller having a determined peripheral speed and positioned tangential to the annular surface to be rubberized at a point of application of the strip; the rotation of the annular surface being controlled so as to maintain the application speed constant; and the section of the strip being controlled by applying to the strip a first drawing, always constant, between the applicator roller and the annular surface to be rubberized, and a further drawing upstream to the first drawing; the further being constant to apply to the annular surface a strip with a constant section, or variable in order to apply to the annular surface a strip with variable section according to a determined law. | 01-29-2009 |
