The usage state of the pretreatment device for a linear body of the present invention will be described below.

In FIG. 1, the filament 2 running in the longitudinal direction.
The felt body 6 slidably contacting with is fed in the direction of arrow A at a speed (for example, 10 mm / minute) which is extremely smaller than the speed (for example, 10 m / minute) at which the filament body 2 runs in the longitudinal direction.

When a stranded wire composed of a plurality of bare wires made of aluminum is used as the filament 2, for example, an oil component such as wire drawing oil or fine dust is formed on the outer surface of the filament 2. Etc. are adhered, but the adhered matter is continuously wiped off in the longitudinal direction by the felt body 6 over the range of the predetermined central angle θ (see FIG. 3). (Thus, the filamentous body 2 is pretreated.)

It should be noted that the felt body 6 has a certain amount of the neutral detergent solution P stored in the washing tank 14 permeated therein, and the neutral detergent solution P is washed from the outer surface of the filamentous body 2 by the washing action. Kimono can be removed efficiently.

The portion (surface) of the felt body 6 which has been soiled by wiping off the deposits on the filament body 2 is sequentially sent to the rough cleaning tank 13,
Rough cleaning is performed with the neutral cleaning agent solution P in the rough cleaning tank 13. By this rough cleaning, fine dust and the like are mainly washed off. In addition, oil such as wire drawing oil is also washed away to some extent.

Next, the felt body 6 that has been roughly washed is sent to the lower washing tank 14. In this cleaning tank 14, the roller
Since the flat portion D of the felt body 6 located between 17a and 17b and its vicinity are immersed in the neutral detergent solution P, the felt body 6
The soiled surface of No. 2 passes through the neutral detergent solution P for a relatively long time. By this (relatively long time) passage, oil components such as wire drawing oil adhering to the felt body 6 are almost completely washed off.

The neutral detergent solution P that has penetrated the felt body 6 that has passed through the neutral detergent solution P in the washing tank 14 is
Rolled down by rollers 15 and 16.

The felt body 6 squeezed by the rollers 15 and 16 is sent to the filament body 2 and wipes off the deposits on the filament body 2 again.

As described above, the adhering of the filamentous body 2 by the felt body 6 (pretreatment) and the cleaning of the felt body 6 by the neutral detergent solution P are continuously performed.

Then, the pre-processed filamentous body 2 is sequentially sent to the transfer roll device 3 shown in FIG. The transfer roll device 3 is provided with a transfer roller 20 and a receiving roller 21 for holding the traveling of the filamentous body 2, and the surface of the filamentous body 2 pretreated by the transfer roller 20 within a predetermined central angle θ. The stripes in the longitudinal direction are transferred to the surface of. In addition, in FIG.
Reference numeral 22 is an air wiper for blowing away the neutral detergent solution P attached to the surface of the filament 2.

Since no oil component such as wire drawing oil or fine dust adheres to the pretreated surface of the filamentous body 2, the coating state of the coating material by transfer is stable and uniform stripes can be formed.

[0045]

The present invention has the following significant effects with the above-mentioned configuration.

(In order that a uniform stripe can be formed on the linear body 2 by the transfer roll device 3) A predetermined central angle θ is applied to oil components such as wire drawing oil and fine dust adhered to the outer surface of the linear body 2. Can be removed (pretreatment) over the longitudinal direction within the range.

Further, it is possible to prevent only a part of the felt body 6 from being contaminated. Further, the neutral detergent solution P stored in the washing tank 14 can wash off oil components such as wire drawing oil attached to the felt body 6. Therefore, the filamentous body 2 can be stably pretreated for a long time. Furthermore, the life of the felt body 6 can be extended.

Further, since the neutral detergent solution P and the soap aqueous solution are harmless to the human body and environment, it is possible to prevent pollution. Further, even when the aluminum filament 2 is used, it is possible to prevent discoloration and corrosion of the filament 2. Further, post-treatment such as washing with water may be unnecessary.
