Abstract:
1. An installation for a surface treatment of parts, comprising a plurality of treatment tanks arranged in series and equipped with rotary drums that are provided with means for temporarily fastening the parts to be treated, the axes of said drums being horizontally mounted so as to rotate and in such a way that most of each drum is immersed in a treatment liquid contained in the corresponding tank, and a conveying line intended to feed each drum with parts to be treated and to remove already treated parts from said drum, wherein the conveying line includes at least one movable carriage undergoing a reciprocating movement causing, by this movement, conveying said parts along a general axis and wherein the axes of the drums are mutually parallel and parallel to the general axis of the conveying line, wherein said means for temporarily fastening parts to be treated comprises at the periphery of each drum a number of slideways having axes parallel to the rotation axis of the drum, wherein all said drums are arranged in such a way that their slideways that come momentarily into the upper position emerge from the treatment liquids and that said slideways come simultaneously into the upper position and are aligned with one another, and wherein said conveying line is configured to operate synchronous and timed transfers of all of the parts located on said slideways that come into the upper positions, said transfers occurring simultaneously at all of said drums.
