Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper surface cleaning method for printing paper, and more particularly to a paper surface cleaning method for removing paper dust, dust, etc. caused by fluff adhering to the surface of printing paper.

If paper powder or dust due to fluffing adheres to the surface of the printing paper, an accident may occur in which this adheres during printing and appears as smudges on the printed matter.

In order to prevent this, conventional methods have been used, such as using a vacuum cleaner to suck up the paper dust and dirt that has adhered to the paper surface, or brushing it off with a brush, and then burning off the deposits with a gas flame. However, none of these methods were perfect and could not completely prevent printing stains caused by deposits.

There is also a method of using a static electricity remover based on the hypothesis that the above-mentioned deposits may be attached due to static electricity, but this method has also not been able to obtain a sufficient effect.

The present invention has been developed in view of the above, and is a method for cleaning the surface of printing paper, which enables almost completely removing deposits such as paper dust attached to the surface of printing paper using an extremely simple method. The paper is arranged in an endless manner on the surface of the printing paper as it moves in a predetermined direction, and along the way, it passes through washing water and is kept in a suitable water-containing state by a squeezing roller. The wiping member made of the hydrophilic substance is brought into contact with the printing paper while being moved in a direction opposite to the direction in which the printing paper is running.

The drawings show an embodiment of the present invention, in which numeral 1 is a printing paper that is applied with a predetermined tension and moves in the direction of the arrow, and 2 is a wiping member made of a hydrophilic substance.

The wiping member 2 has an endless shape wrapped around rollers 3, 4, 5, 6, and 7, and is passed through cleaning water 8 along the way, and is brought into a suitable water-containing state by a squeezing roller 9. After the paper has been squeezed, it is brought into contact with the printing paper 1 while being moved in the direction of arrow B, that is, in the opposite direction to the direction of travel of the printing paper 1, to remove and clean paper dust and the like on the surface of the printing paper 1. be.

In the drawing, 10 is a brush for cleaning the wiping member 2, and the rollers 3, 4, 5,
One of the rollers 6 and 7, 5, is a tension roller.

Further, when the wiping members 2 are provided symmetrically on the left and right sides of the printing paper 1 as shown in the figure, the arrangement of the printing paper 1 is facilitated by making one of the wiping members 2 movable in the direction of arrow C. .

As described above, in the method for cleaning the surface of printing paper according to the present invention, the printing paper is arranged in an endless manner on the surface of the printing paper as it runs in a predetermined direction, passes through washing water on the way, and is preferably used with a squeezing roller. Since the wiping member made of a hydrophilic substance in a water-containing state is brought into contact with the printing paper while running in the opposite direction to the running direction of the printing paper, most of the deposits such as paper powder adhering to the surface of the printing paper can be removed. Not only can it be completely removed, but it is also extremely inexpensive and easy to handle because it uses water, which was previously not used in printing paper due to its problems such as decreased tensile strength, expansion and contraction, and curling. Moreover, since the wiping member is endless, it not only contributes to resource saving, but also because it is constantly washed with washing water, it is possible to remove and clean the deposits on the surface of the printing paper over a long period of time. It only requires replacing the washing water from time to time, and its maintenance costs are extremely low.

[Brief explanation of the drawing]

The drawings are explanatory diagrams showing embodiments of the present invention. 1 is printing paper, 2 is wiping member.

Claims (1)

[Claims] 1.
