Abstract
The machine includes a first winding roller and a concave plate extending around the first winding roller. The first winding roller and the concave plate define a feed channel of the web material. Upstream of the concave plate there is arranged a moving member including a pinching surface cooperating with the first winding roller to pinch the web material against the first winding roller. The moving member is arranged and controlled to pinch the web material against the surface of the first winding roller and decelerate the web material between the moving member and the surface of the first winding roller, causing a leading edge to wind around itself to form a winding nucleus of a log.
