Abstract
A vectorial assembly method for first and second stage assemblies (5, 3) of radial tires, whereby a first stage assembly (5), mounted on a rotary inner support (52) so as to rotate about its axis, and a second stage assembly (3), housed inside a toroidal body (7) mounted for rotation, about a horizontal axis (8), on a supporting saddle (31) adjustable about a vertical axis (21), are rotated for determining their respective unbalance vectors, and are assembled, the first (5) inside the second (3), in relative angular positions such as to minimize the unbalance vector of the assembled tire.
Claims5
A vectorial assembly method for first and second stage assemblies of road vehicle tires, the method comprising the steps of placing the first stage assembly about a first support rotatable about a first axis;
- placing the second stage assembly inside a second support comprising a toroidal body rotatable about a second axis coaxial with the second stage assembly;
- rotating the first and second stage assemblies about their respective axes, for detecting the respective imbalanced vectors;
- positioning the assemblies such that the resulting imbalanced vector is minimized;
- inserting the first stage assembly inside the second stage assembly after arranging the two assemblies in such relative angular positions as to form a tire having said minimized resultant imbalanced vector;
- and mating the two assemblies.

- rotating the first and second stage assemblies about their respective axes, for detecting the respective imbalanced vectors;
- rotating at least one of the first stage assembly and second stage assembly about a third axis such that the first axis of the first support and the second axis of the second support are angled relative to one another;
- inserting the first stage assembly inside the second stage assembly after arranging the two assemblies in such relative angular positions as to minimize the resultant imbalanced vector of the assembled tire;
- maintaining the angle between the axes of the first support and the second support while moving the supports, so angled, in relation to each other so that the center of one of the supports coincides with the center of the other of the supports;
- rotating at least one of the supports in relation to the other about the third axis until the axis of the first stage assembly and the axis of the second stage assembly are parallel;
- and mating the two assemblies.
