REWINDING MACHINE AND METHOD FOR PRODUCING LOGS OF WEB MATERIAL

摘要

The machine comprises a first winding roller (3) and a concave plate (17) extending around the first winding roller (3). The first winding roller and the concave plate define a feed channel (19) of the web material (N). Upstream of the concave plate (17) there is arranged a moving member (21) comprising a pinching surface (23B) cooperating with the first winding roller (3) to pinch the web material (N) against the first winding roller (3). The moving member (21) is arranged and controlled to pinch the web material (N) against the surface of the first winding roller (3) and decelerate the web material between the moving member (21) and the surface of the first winding roller (3), causing a leading edge (LT) to wind around itself to form a winding nucleus of a log (L; L1).
