Abstract: The invention relates to a method of coating a surface (2) of a hollow body (1), said method comprising: a step of positioning said hollow body (1) on a support (7) designed to receive said hollow body (1); and a step of spraying at least one coating material onto said surface (2) of said hollow body (1) by means of a spray device (9), relative movement being imparted to said support (7) and to said spray device (9); said coating method being characterized in that said relative movement takes place at a velocity that varies as a function of the distance (d) between the spray device (9) and said surface (2). Coating machines.

Abstract: A method of decorating by pad printing for applying a decorative pattern (2) on the wall (3) of a previously-shaped part (4) to be decorated, such as a glass bottle, including a preparation step a) during which a liquid marker substance (5) of any viscosity is deposited in the imprint (11, 111) of a pad-die (10, 110) that is marked by an indentation of shape that is substantially complementary to the shape of the existing wall (3) of the part (4) to be decorated, which substance may be an ink or an enamel, and then a marking step b) during which the pad-die (10, 110) is moved towards the part (4) so as to bring the wall (3) of the part into contact with the bottom of the imprint (11, 111), so as to deposit the decorative pattern (2) on the wall (3) by transferring the marking substance (5) from the imprint onto the wall for decorating and marking objects.
