Abstract
1. A pallet for making concrete roofing tiles in an extrusion process, consisting of an upper shell (10) and a lower shell (20), which are made of pressed sheet steel and welded together, the upper shell (10) having a central bulge (30) extending in longitudinal direction, characterized in that the upper shell (10) has on each of its two longitudinal sides an edge bulge (37 or 39 respectively) and that the lower shell (20) has at least two transverse grooves (40) which extend in their height up to the upper shell (10) and which are connected with the upper shell (10) at flat parts (31) located between the central bulge (30) and the edge bulges (37, 39) by spot welding.
