Claim:
A workpiece carrier for a pallet ( 1 ), having at least two support elements ( 15 , 16 ) for workpieces ( 20 ) comprising: two parallel reference bars ( 3 ), fixed to the pallet ( 1 ); two fastening bridges ( 4 ) substantially orthogonal to said bars ( 3 ), having a central portion, on which said support elements ( 15 , 16 ) are connected, and two ends ( 4 ′) suitable for a boltless positive engagement ( 3 ′, 6 ) with said bars ( 3 ), wherein said positive engagement ( 3 ′, 6 ) is accomplished directly between said fastening bridges ( 4 ) and said bars ( 3 ) with no other fastening device, and wherein said bridges ( 4 ) have said ends ( 4 ′) with an inclined face, and said bars ( 3 ) have an inclined surface, whereby the positive engagement ( 3 ′, 6 ) is achieved when the inclined faces of the bridges ( 4 ) and the inclined surfaces of the bars ( 3 ) match with each others; the distance between said support elements ( 15 , 16 ) being adjustable by raising one of said bridges ( 4 ) from said bars ( 3 ), moving it to another position and lowering it again for completing the positive engagement ( 3 ′, 6 ) with the bars ( 3 ) in the new position.
