(57) The apparatus (100) includes a ring-like, endless band (10), stretched between a
motor roller (11) and a lower cusp (12), whose tip (120) is rounded and turned downward.
The band (10) has pits (1) on its outer surface, which define the decoration pattern
to be obtained by powder enamel (S) introduced into the pits (1) in a filling station
(R), upstream of the tip (120) of the cusp (12). A decoration station (D) is situated
at the tip (120) of the cusp (12), where the pits (1) are emptied, due to gravity,
and the enamel (S) falls on the tile (2) passing therebelow. The apparatus (100),
according to the invention, includes the filling station (R), situated close to the
rounded tip (120), immediately upstream of the decoration station (D). For this purpose,
the idler roller (31) of a belt (30), associated to the band (10) and tangential thereto
in the filling station (R), has a small diameter, preferably such that that the curvature
radius imposed to the belt (30) is similar to the one imposed to said band (10) by
the rounded tip (120).
