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).

A coating machine for coating a surface (2) of a hollow body (1) made of glass and constituting a container designed to receive one of food products, pharmaceutical products or cosmetic products, said coating machine including a support (7) designed to receive said hollow body (1) and a spray device (9) designed to spray at least one coating material onto said surface (2) of said hollow body (1), said support (7) and said spray device (9) being designed to have relative movement imparted to them, said coating machine being characterized in that it is designed so that said relative movement includes rotation of said support (7) taking place at a velocity that varies as a function of the distance (d) between said spray device (9) and said surface (2), while the spray device (9) is spraying said at least one coating material.
A method of coating a surface (2) of a hollow body (1) made of glass and constituting a container designed to receive one of food products, pharmaceutical products or cosmetic products, 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 includes rotation of said support (7) taking place at a velocity that varies as a function of the distance (d) between the spray device (9) and said surface (2).
