The adoption of the suction pick up roll in transferring the wet sheet from the Fourdrinier wire to the press part has resulted in higher speed of paper making and lower frequency of paper breakage than by open system. However, since the suction roll is of complex construction and has to be connected with a vacuum pump, it is very expensive to install and operate .
The postup transfer installation we have developed is free from the above disadvantages, simple in construction capable of efficiency detaching the wet sheet from the wire, and able to transfer to the press part.
The principles and construction of this installation are described, and the plan designed, by Asahi Iron works Co. is illustrated herein.
