Abstract

For the transportation-storage and assembly stacking of electric hotplates (2), a stacking air has pallet plates (10) to be arranged in superimposed manner in stacking layers and which can be directly stacked in one another for storage and which are in the form of deep drawn plastic plate parts with grid-distributed flat shells (19), which in each case projecting beyond the open side with the cooking surface (4) receive in centering manner the lower part of an electric hotplate (2) and are supported with respect to the cooking surfaces of the adjacent stacking layer by means of a slide preventing means (31), but are otherwise contact-free. Thus, on a support pallet and protected by a packing sleeve it is possible to stack a very large number of hotplates (2) in a stable manner, with the same orientation and therefore having good assembly access. Following an assembly process performable fully automatically with programmable handling means, the in each case necessary hotplates (2) are set down oriented upside down and then a mounting plate is mounted upside down and secured with a locking part with respect to the hotplates. Then, optionally by spot welding joints, the connecting mem…
