A coreless scroll rewinding machine without a winding assisting plate comprises an upper rewinding roller (1) and a lower rewinding roller (2) that are parallel with each other. Paper (3) is wound on the upper rewinding roller (1) and passes through a gap between the upper and the lower rewinding roller (1, 2). Multiple airflow channels (4) are formed in a roller body of the lower rewinding roller (2), and each of the airflow channels (4) is communicated with a group of air entry ports (5) on a surface of the roller body. An suction cover (6) provided with a suction port is arranged near an end of the lower rewinding roller (2). When one group of air entry ports (5) on the surface of the lower rewinding roller (2) is adjacent to the gap between the rollers, the airflow channel (4) communicated with the group of air entry ports is rotated to an area communicated with the suction port of the suction cover (6). When the group of air entry ports (5) is far away from the gap between the rollers, the corresponding airflow channel (4) is rotated to an area deviated from the suction port. This coreless scroll rewinding machine has high winding reliability, stable rewinding function and uniform scroll compactness, and can prevent the indentation on the surface of the scroll. |
