发明名称 Cylindrical suction box assembly
摘要 The present invention provides a cylindrical suction box assembly with a suction box having two or more suction chambers that operate at different suction pressures. A lower suction pressure suction chamber is configured to provide lower suction pressure suction and is used in conjunction with the texturing process. At least one higher suction pressure suction chamber is configured to provide higher suction pressure suction and is used in conjunction with the de-watering process of the present invention. Therefore, according to the present invention two processes that are traditionally performed on two different devices are performed on a single cylindrical suction box assembly.
