Abstract
A paper box forming machine includes a machine body and a mandrel rotatably mounted around an axle of the machine body. A pressing device movable relative to the mandrel includes a frame having upper and lower portions and first and second side portions extending between the upper and lower portions. A tunnel extends from the first side portion through the second side portion and has a size larger than the mandrel. A pressing plate is provided to an inner side of each of the upper and lower portions and the first and second side portions. The pressing plates are actuatable to move relative to and in the frame to exert pressure on an outer periphery of the mandrel to make a paper box body from a corrugated paper layer wound around the outer periphery of the mandrel.

A paper box forming machine comprising:
- a machine body (22) including an axle (28) extending along a longitudinal axis;
- a mandrel (24) rotatably mounted around the axle (28), with the mandrel (24) including an outer periphery surrounding the longitudinal axis, with a corrugated paper layer (66) adapted to be wound around the outer periphery of the mandrel (24);
- and
- a pressing device (26) movable relative to the mandrel (24) along the longitudinal axis, with the pressing device (26) including a frame (78) having upper and lower portions (80, 82), with the frame (78) further including first and second side portions (84) extending between the upper and lower portions (80, 82), with a tunnel (86) extending from the first side portion (84) through the second side portion (84) along the longitudinal axis, with the tunnel (86) having a size larger than the mandrel (24), with the a pressing plate (88) provided to an inner side of each of the upper and lower portions (80, 82) and the first and second side portions (84), with the pressing plates (88) being actuatable to move relative to and in the frame (78) to exert pressure on the outer periphery of the mandrel (24),
- wherein with the corrugated paper layer (66) wound around the outer periphery of the mandrel (24), the pressing device (26) is moved to a position in which the mandrel (24) is received in the tunnel (86) of the frame (78), and the pressing plates (88) are actuated to exert pressure on the outer periphery of the mandrel (24) to make a paper box body (114) from the corrugated paper layer (66) wound around the outer periphery of the mandrel (24).
