The work-carrier stand consists of stacking frames (1.2) which can be put onto a base frame (1.1) and in which transport cassettes (4) can be inserted in each case. The transport cassettes (4) can be subdivided at variable distances apart transversely to their longitudinal axis by dividing-wall elements (5.1 or 5.2) so that, for example, round workpieces (W), when put on, are automatically orientated parallel to the longitudinal axis and are held at the same distance (A) apart. Thus, exactly reproducible robot access becomes possible, because axial distance identity or 0-point orientation to marginal stops is achieved by a dividing wall (5.2) with a leaf spring (6) braced on the workpiece side being provided in front of one end face of each of the workpieces (W). Here, the top margin (10) of the dividing wall (5.2) comes to lie only just above the centre of a conventional workpiece (W) so that unimpeded gripper access from above with exact preset positioning via NC programs or the like is ensured. Furthermore, reliable selection of each workpiece position is guaranteed by diverse centring measures (2.3, 3.5, 4.4) on columns (2.1, 2.2), frames (3.1 and 3.2) and supporting V-blocks (4.2) or supporting bases (4.5). <IMAGE>
