Devices (11,12) are provided for the positioning at the correct height and with reciprocal spacing of the locating dishes (45), which form part of a profiled plate. The profiled plate (12) has a regular backwardly facing pattern of bowl-shaped pattern units with a four-sided contour. Each bowl-shaped pattern unit has a flat baseplate and four bowl walls upwardly directed on the side edges of the baseplate. The bowl walls of abutting pattern units at their upper outer ends evolve into each other and thus define a ridge (43) with a conical, preferably triangular cross-section.
