[Technology of Invention Er-1 Background and 181 Points] In the four paper making machines, the same machine is used to produce paper that is divine. The basis weight is changed.However, depending on the raw material conversion, the dehydration rate and drying rate of each part also change the optimum draw in each section. When writing paper history (Yu has to adjust the draw of each section each time, and there are many cases where it is not possible to change the paper smoothly).
