SURFACE TREATMENT DEVICE AND SURFACE TREATMENT METHOD FOR LONG LINEAR ARTICLES

摘要

Provided are a surface treatment device and surface treatment method for long linear articles, the device and method being configured so as to be able to polish the surface of long linear articles efficiently using a powder by cyclically repeating the pressurization and depressurization of an elastic tube filled with the powder. To that end, the device comprises at least one surface treatment unit (20A-20C, 120) and the surface treatment unit is provided with: a tube (22) which is filled with a powder (21) so as to allow supply and discharge and in which a long linear article (10) is movably inserted in the powder; pressurizing means (31, 32) that cyclically pressurize and depressurize the tube; and a feed means (19) for moving the long linear article inserted in the powder.
