The present invention relates to a device (10) for the surface processing of a substantially round bar (200) comprising support and/or advance means (120', 120") and abrasion means for the bar (200). The abrasion means comprise a first movable working support (110') and a second movable working and/or contrast support, wherein at least the first working support (110') is provided with abrasive tape (250' 250"). The two movable supports (110', 110") are opposite and in operating mode they are constantly in contact with the bar (200), optionally interposing the abrasive tapes (250', 250"), and keeping a fixed distance between centres between the same movable supports (110', 110"). |
