る。 However, such conventional suction rollers require hundreds to hundreds of thousands of small holes depending on the roller size and application, so the drilling process requires advanced technology and a long time, making it very difficult to use. It is difficult to avoid being expensive. Further, the diameter of the small hole must be at least 0.5 mmφ due to technical limitations such as processing methods. For this reason, thin base materials, unmolded plastic sheets, and the like are inconveniently dug into small holes by negative pressure, resulting in unevenness and quality deterioration.
