Discs (7) arranged along a shaft and having holders (8) distributed over the circumference, inclined outwards and intended for workpieces are supported on a ring (5) surrounding the discs (7). Successive rings (5) form an approximately cylindrical cladding which prevents undesired coating of the discs (7). Cladding has openings for the holders (8) of a disc (7) which are uniformly distributed over the circumference at the same height, each formed by an upper recess (14) in the ring (5) carrying the disc (7) and an adjacent lower recess (15) of the following ring. Boundary lines (17) between successive rings (5) start somewhat below the narrowest points of the webs separating adjacent openings, so that the lower recesses (15) do not narrow towards the edge of the ring (5) and the upper recesses (14) narrow at most slightly so that the workpiece carrier can be assembled from bottom to top.
Workpiece carrier for a coating system, comprising a base (2) and a shaft (1) anchored or mounted therein and a plurality of discs (7) which follow one another along the shaft (1) and are rotatable relative to the base (2) and which in each case are provided with a plurality of holders (8) distributed over the circumference of the disc (7), inclined obliquely outwards away from the shaft (1) and intended for a workpiece (13), characterized in that said workpiece carrier has a cladding which surrounds the shaft (1) and the discs (7) and leaves free groups of openings which are distributed over the circumference and separated in each case by webs, through which openings in each case the holders (8) belonging to one of the discs (7) project, and which is composed of a plurality of rings (5) which follow one another along the shaft (1) and are directly adjacent to one another and which abut at boundary lines (17) which in each case divide one of the webs present between adjacent openings of a group.
