Machine for printing a poultry egg

Machine for printing eggs comprising a support for the egg to be printed, a first inking pad for printing by tampography and a first mechanism for placing the inking pad in contact with the egg on the support and for moving it away, wherein the support comprises two pairs of facets, each facet being inclined in relation to the vertical, moving away from the vertical from the bottom to the top, and the facets of each pair forming between them an angle of between 60.degree. and 120.degree., the distance between two facets of the same pair being less than the smallest dimension, in horizontal projection, of an egg, and the distance between two facets of two different pairs being less than the largest dimension, in horizontal projection, of an egg, and substantially only the facets of the support extend below the egg, said facets supporting said egg at spaced locations along its contour and defining an opening below the egg between said locations, the first inking pad being displaced by the first mechanism in a substantially horizontal direction, along the plane bisecting the dihedral formed by one of the pairs of facets.
