Abstract: A coreless paper roll rewinding machine without a winding assisting plate comprises a rewinding upper roller (1) and a rewinding lower roller (2) that are parallel with each other. Paper (3) is wound on the rewinding upper roller (1) and passes through a roller gap between the rewinding upper roller (1) and the rewinding lower roller (2). A plurality of airflow channels (4) are formed in a roller body of the rewinding lower roller (2), and each of the air flow channels (4) is interconnected with a set of air suction holes (5) on the surface of the roller body. An air suction cover (6) provided with an exhaust opening is arranged close to the end of the rewinding roller (2). When one set of air suction holes (5) on the surface of the rewinding lower roller (2) is close to the roller gap, one of the air flow channels (4) interconnected with the set of air suction holes is rotated to a region interconnected with the exhaust opening of the air suction cover (6).

Abstract: A coreless paper roll rewinding machine using air flow to assist starting winding is mainly characterized in that: an air pipe (11) blowing air downwards is arranged above a rewinding lower roller (2); the roller gap (M) between a rewinding upper roller (1) and the rewinding lower roller (2) is no more than 10 mm; a plurality of air flow channels (4) are distributed in the roller body of the rewinding upper roller (1); a plurality of sets of air suction holes (5) are formed on the surface of the roller body; each set of the air suction holes (5) are interconnected with each air flow channel (4) formed in the roller body; an air suction cover (6) is arranged in the position close to the end part of the rewinding upper roller (1); and each air flow channel (4) formed in the roller body is interconnected with or disconnected with the air suction holes of the air suction cover (6) in turn along with rotating of the rewinding upper roller (1).
