浄して付着物を取り除く必要がある。2. Description of the Related Art Cloths such as wires, felts and canvases are used in a paper machine. These papermaking cloths are used for the papermaking machine while the paper machine is in operation. If the additive substance adheres and continues to be used as it is without removing these deposits, the deposits grow to cover the entire surface of the papermaking fabric, and the water-permeability is impaired, and not only the dehydration efficiency decreases, but also The increased load shortens the life of the papermaking fabric, and further causes the inconvenience of lowering the quality of the product. For this reason, it is necessary to wash it appropriately to remove the deposits.

がある。However, the cleaning device that has been conventionally used for cleaning the cloth for papermaking has a structure in which the cleaning liquid is sprayed on the cloth for papermaking and the deposits are blown off by the pressure of the cleaning liquid. In this case, since the cleaning liquid collides with the papermaking fabric at a high pressure in this case, it has a great influence on the papermaking fabric and has a disadvantage that the life of the papermaking fabric is shortened. Moreover, when the cleaning liquid collides with the papermaking fabric, a large amount of splash liquid is generated, and this splash liquid not only pollutes peripheral equipment but also drops on wet paper and causes paper breakage, so promptly It is necessary to collect them, which is troublesome in the processing. Further, in the configuration in which the high-pressure cleaning liquid is jetted, there is a disadvantage that the consumption of the cleaning liquid is large, the power cost is required for pressurization, and the operation cost increases due to replacement of the nozzle, which is significantly worn.

According to this, since the cleaning liquid sprinkled on the surface of the papermaking fabric is immediately pushed into the inside of the papermaking fabric by the rolls, it is possible to suppress the dripping and allow a large amount of the cleaning liquid to permeate the papermaking fabric. Therefore, in combination with the low pressure of the cleaning liquid, waste of the cleaning liquid is reduced and the amount of the cleaning liquid used can be reduced.

It is possible to adopt a configuration in which the roll is rotated relative to the papermaking fabric so that the paper slides. According to this, the ridges move so as to rub the surface of the papermaking fabric, and the papermaking fabric sways in a wavy manner. Therefore, a kneading washing effect can be obtained, and the washing effect can be further enhanced. Even if the roll is not slid against the papermaking fabric, pressing the papermaking fabric against the roll with appropriate tension causes the papermaking fabric to be deformed into a wavy shape and partially compressed, which results in press washing. The effect is obtained.

ることができる。The roll 2 is provided with a protrusion 10 extending on the outer peripheral surface in a state of being inclined with respect to the circumferential direction. This ridge 10 is formed in a spiral shape and deforms the papermaking fabric 1 pressed against the roll 2 by tension so that the cross section has a corrugated shape, and thereby the papermaking fabric 1 is partially compressed and pressed. A washing effect is obtained. The surface 1a of the papermaking fabric 1
The roll 2 is rotated relative to the papermaking fabric 1 so that the ridge 10 slides. Therefore, the ridge 10 operates so as to rub the surface of the papermaking fabric 1, and accordingly, the papermaking fabric 1 sways in a wavy manner, functioning similarly to a washing plate to obtain a kneading washing effect. This makes it possible to lift up the adhered matter that is strongly entangled with the fibers of the papermaking fabric 1.

The roll 2 is rotated at a speed lower than the traveling speed of the cloth 1. The roll 2 may be driven by a motor at a speed higher than the traveling speed of the papermaking fabric 1. The ridges 10 are formed symmetrically with the axial center of the roll 2 as a boundary, so that the forces acting on the papermaking fabric 1 from the roll 2 slidingly contacting the papermaking fabric 1 are balanced, and the papermaking fabric 1 is formed. Can be stably driven.

A required amount of the cleaning liquid is supplied to the papermaking fabric 1, and then, in the fabric deformation step by the roll 2, the cleaning liquid is spread over the papermaking fabric 1 and the cleaning liquid is soaked in the papermaking fabric 1.
Is deformed into a corrugated shape so that the deposits entangled with the fibers of the papermaking fabric 1 are lifted up, and most of the deposits attached to the surface of the papermaking fabric 1 are scraped off by a doctor blade 4 scraping process thereafter. Thus, the deposits on the papermaking fabric 1 are efficiently removed. In the scraping step, the pitch firmly attached to the papermaking fabric 1 can also be removed.

ができる。In the present embodiment, an example in which a spiral protrusion is provided to form irregularities on the outer peripheral surface of the roll has been shown, but the present invention is not limited to this, and various types of protrusions can be used. The form is possible. For example, as shown in the arrangement pattern of the protrusions in FIG. 3, the protrusions 22 may be provided on the outer peripheral surface of the roll 21 in a lattice-like manner. Further, as shown in FIG. 4, the protrusion 32 may be provided on the outer peripheral surface of the roll 31 in a corrugated manner. In any of these configurations, the ridges 22 and 32 are inclined with respect to the circumferential direction of the rolls 21 and 31, and by operating the ridges 22 and 32 to slide on the papermaking fabric 1, a kneading effect can be obtained. it can.
