Abstract
A straw forming machine includes a feeding device, a pressing device, a sticking device, a conveyor device, and a cutting device. The paper material is stretched from the feeding device to the pressing device which curls the paper material. When the paper material is delivered to the sticking device, the two sides of the paper material are pressed by the sticking device to form the paper pipe, and the press roll of the sticking device rolls and sticks the two abutting portions of the paper pipe. Then, the paper pipe is delivered by the conveyor device to the cutting device which cuts the paper pipe to form drinking straws.
