The conventional paper-manufacturing system is composed of a head box (10), an out wire part (20), an inner wire part (30), press part (40) and a dryer part (50).
Fig. 1 is a system for showing conventional paper-manufacturing processes.
The conventional paper-manufacturing system is composed of a head box (10), an out wire part (20), an inner wire part (30), press part (40) and a dryer part (50).
(1) The head box (10) located at the lower part between the our wire part (20) and the
inner wire part (30) is the part for distributing pulp fluid for manufacturing paper on mesh of the
wire belt (25) and plays an important role for distributing the pulp fluid uniformly on the mesh of
the wire belt (25) having broad width (the width 3~ 5m) and high speed (1500m/min equivalent to
90km/h).(The concentration of the average pulp fluid is about 15% of the pulp content).
(2) The out wire part (20) is composed of the wire roll (21), the wire guide roll (22), the
water tray (23), the forming roll (24) and the wire belt (25), and plays a role for enabling the wire
rolls (about 5~ 6 rolls) (21) to rotate the wire belt (25) around the wire loop. The diameters of the
wire rolls are different in accordance with the speed and the width and are about 300 ~ 500mm.
The surface of the wire rolls is composed of elastomer such as rubber and other elastic materials.
The wire guide roll (22) plays a role of performing automatic return of the wire belt (25)
for enabling the wire belt (25) to continuously run without escaping from the central orbit and is
coated with an elastomer such as rubber like the wire roll.
The pulp fluid which is supplied on the mesh of wire belt (25) from the head box (10) is
composed of about 99.8% or more of water and about 0.2% or below of pulp and a large amount of
water is discharged outside the wire box. The water tray (23) is a tub for taking in and moving
water instantaneously discharged from wire box.
The forming roll (24) is a large-sized driving roll and rotates with making out wire part
(20) and wire belt (25) contact concurrently. Dehydrating and sheet forming are accomplished on
this forming roll (24).
The wire belt (25) is equipped with a net for discharging and filtering water after receiving
dilute pulp fluid.
(3) The inner wire part (30) is composed of the wire roll (31), the wire guide roll (34), the
pick up roll (32) and the inner wire belt (33). The inner wire belt (33) is linked and geared with the
forming roll (24). The wire roll (31) and the wire guide roll (31) play the same role as in the out
wire part (20).
The inner wire part plays a role for transferring the formed wet paper to the felt of the
press part.
The pick-up roll (32) transfers the wet paper transferred onto the inner wire part onto the
felt and adsorbs the wet paper by producing vacuum and transfers the wet paper onto the felt.
The vacuum box which is not shown in the drawings, sucks the wet paper formed on the
forming roll at the time of separating the out wire and the inner wire and transfers the wet paper
onto the inner wire.
The inner wire belt (33) is a net like out wire loop but has a more dense structure in order
for the wet paper to be transferred onto the inner wire.
(4) The press part (40) is composed of the suction press roll (41), the second touch roll
(42), the felt guide roll (43), the felt roll (44) and the felt (45).
The suction press roll (41) linked with the inner wire part (30) is a vacuum roll for
pressing moisture of wet paper to the dryer surface with high pressure and absorbing the water.
The outer shell rotates. However as the outer shell is equipped with vacuum box inside discharges
the dehydrated water to the outside.
The second touch roll (42) is a press roll for removing moisture of the dehydrated wet
paper from the suction press roll (41) for the second time. The second touch roll (42) is a
perforated plain roll of no vacuum.
The felt roll (44) enables the felt to rotate following by the felt loop.
The felt guide roll (43) plays a role of performing automatic return for enabling the felt to
continuously run without escaping from the central orbit.
The felt (45) plays a role of conveyer for transferring the wet paper and provides
protection of the wet paper from damage in the case of pressing and dehydrating the wet paper.
In the conventional paper manufacturing system, pulp fluid discharged from the head box
are supplied between the out wire belt (25) and the inner wire belt (33) which lies one upon
another and rotate around the forming roll (24). The dilute pulp fluid is dehydrated by pressure of
tension of the out wire belt (25). The wet paper filtered by the out wire and the inner wire is firstly
adhered and transferred onto the inner wire and secondly transferred onto the felt by vacuum of
pickup system. The wet paper on the felt secondly is dehydrated (strongly dehydrated) on the
suction press roll and the second touch roll and is transferred and dried onto the Yankee dryer.
However, this conventional method has been continuously performed nearly 100 years or
over without any change or improvement of the main skeleton of the processes of paper
manufacturing.
Consequently, there have been some problems, for example, low quality, decrease of
flexibility, decrease of strength, increase of pin hole and decrease of productivity, etc.
The present inventor has being studied for improving such problems of the conventional
paper-manufacturing system for a long time and finally completed the present invention.
Therefore, the present invention provides a new improved paper-manufacturing system.
The present inventor omitted the function of the inner wire part from the conventional
paper- manufacturing system and shortened three processes into two process by replacing the
function of the inner wire part with the felt loop. The rotations of out wire and the forming roll
were reversed and the head box located at the lower part between the our wire part (20) and the
inner wire part (30) is equipped at upper part between the our wire part (20) and the felt (33) and
the supply function of pulp fluid is greatly improved. The dehydrating function, one of the three
core function of paper-manufacturing system, is greatly improved (a high-speed function). The
paper quality is quietly improved by improving the forming function. Pick up function and
transferring function (transferring function of wet paper) are greatly improved. Accordingly, the
conventional paper-manufacturing system can be greatly improved without any installation or any
investment by the present invention.

paper-manufacturing system.
