摘要:
A process and apparatus for improving paper formation on an open surface paper making machine is described. By the use of both a path for the forming fabric which introduces a controlled level of agitation into the stock, and a low level of vacuum in a suction box extending continuously for the forming section, improvements both in paper quality, such as improved wire mark, and in machine operation, such as an improved first pass retention, are obtained.
