| 发明名称 | Rewinding machine and method for producing logs of web material | ||
| 摘要 | 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. | ||

| 主权项 | 1. A rewinding machine for producing logs of web material, comprising a first winding roller; a concave plate facing the first winding roller, said first winding roller and said concave plate defining a feed channel for web material; a feed path of the web material extending along said channel; upstream of said concave plate, a moving member having a pinching surface structured to cooperate with said first winding roller to pinch the web material against the first winding roller; wherein said moving member is arranged and controlled to pinch the web material against a surface of the first winding roller and decelerate the web material between the moving member and the surface of the first winding roller to cause a leading edge of the web material to wind around itself to form a winding nucleus of a log. | ||
