A method for winding a rubber strip onto a form of revolution includes steps of: forming a strip of predetermined length, applying front and rear edge marks to the strip, driving the strip towards the form, arranging a front edge of the strip on the form, and driving the form to wind the strip onto the form. In a first phase, the driving of the strip and the driving of the form are synchronized so as not to modify the length of the strip. In a second phase, the driving of the strip and the driving of the form are controlled depending on an angular position of the form and on a position of the rear edge mark, in order to vary relatively a displacement speed of the rear edge mark and a displacement speed of the front edge mark, to compensate for variations in the length of the strip.
