Abstract:
1. A method of winding one end (E) of a cylindrical sleeve (C) of axis XX′ around a toric ring (R) with an inside diameter substantially equal to that of the cylindrical sleeve (C), so that the end (E) of the cylindrical sleeve is engaged between the toric ring (R) and the cylindrical sleeve (C) itself in order to make at least one complete turn around a substantially circular radial section of the toric ring (R), wherein the method comprises the steps of: disposing in an open position a winding device (D) comprising a winding fabric (T) formed by a sleeve having two ends (P introducing the tone ring (R) on the end (E) of the cylindrical sleeve (C) into an annular housing (L) formed by portions of the loops (B) and the winding fabric (T); radially lowering the set of winding heads concentrically so that the winding fabric (T) grips an assembly formed by the tone ring (R) and the cylindrical sleeve (C) over more than half of a circumference of said assembly; tensioning the winding fabric (T) along axis XX′; moving the set of winding heads in an axial direction (D releasing the tension on the winding fabric (T) and radially lifting the set of winding heads; and extracting the cylindrical sleeve (C) wound around the toric ring (R).
