1. need not to help the coreless rolls rewinding machine of roll bending, comprise the rewinding top roll and the rewinding lower roll that are parallel to each other, paper passes through on the rewinding top roll and the roll gap between rewinding top roll and rewinding lower roll, it is characterized in that:

  • the roll gap between rewinding top roll and the rewinding lower roll is not more than 10 millimeters, in the roll body of rewinding lower roll, be distributed with many gas channels, many gas channels are spaced along the circumferencial direction of roll body, each bar gas channel is communicated to one group of air suctiton inlet on roll body surface, same one group of air suctiton inlet that gas channel was communicated with is arranged in a row or more on the roll body surface, each row'"'"'s air suctiton inlet is arranged along the length direction of roll body, each is arranged air suctiton inlet and is spaced along the circumferencial direction of roll body, be provided with suspended hood in position near roll end under the rewinding, rotation along with the rewinding lower roll, when certain row'"'"'s air suctiton inlet on rewinding lower roll surface draws near near the roll gap between rewinding top roll and the rewinding lower roll, gas channel in the roll body that this row'"'"'s air suctiton inlet is communicated with turns to the zone with the corresponding connection in the inlet scoop of suspended hood, when certain row'"'"'s air suctiton inlet on rewinding lower roll surface during from the close-by examples to those far off away from the roll gap between rewinding top roll and the rewinding lower roll, the interior gas channel of the roll body that this row air suctiton inlet is communicated with turns to the zone of departing from the inlet scoop of suspended hood.
