Equipment for the enameling of manufactured articles, comprising: an internally hollow container for the collection of enamel to be applied on a manufactured article, where said container is provided with at least one group of through orifices for the outflow of the enamel; at least one roller housed out of axis inside said container and operable in rotation around a relevant axis, electronic control means for controlling the rotation of said roller around the relevant axis, where the volume interposed between the inner walls of said container and said roller defines a containment chamber of the enamel, said orifices protruding inside said containment chamber; where said roller is provided with at least one set of protrusions adapted to open and close said orifices during the rotation of the roller itself to allow and prevent respectively the enamel from flowing out of said container and wherein it comprises movement means for moving the manufactured article to be enameled along a direction of forward movement, sensor means, adapted to detect the position of the manufactured article to be enameled in relation to said orifices and by the fact that it comprises at least one command and control unit which is operationally connected to said movement means, to said sensor means and to said control means, where said command and control unit is configured to control the rotation speed of said roller around the relevant axis according to the position of the manufactured article with respect to said orifices and to its forward movement speed so as to vary the quantity and/or frequency of the enamel dispensed through the orifices themselves, i.e. the distance between two successive dispensing operations along the direction of forward movement, or to control said movement means to vary the forward movement speed of the manufactured article, the rotation speed of said roller being equal, and characterized by the fact that said roller comprises a plurality of said sets of protrusions angularly spaced apart from one another along the circular extension of the roller itself, said orifices being opened and closed in a sequential and cyclic way, i.e., with a determinate frequency, following the transit of each set of protrusions at said group of orifices defined on the container, giving rise to a substantially punctiform application on the manufactured article. an internally hollow container for the collection of enamel to be applied on a manufactured article, where said container is provided with at least one group of through orifices for the outflow of the enamel; at least one roller housed out of axis inside said container and operable in rotation around a relevant axis, electronic control means for controlling the rotation of said roller around the relevant axis, where the volume interposed between the inner walls of said container and said roller defines a containment chamber of the enamel, said orifices protruding inside said containment chamber; where said roller is provided with at least one set of protrusions adapted to open and close said orifices during the rotation of the roller itself to allow and prevent respectively the enamel from flowing out of said container and wherein it comprises movement means for moving the manufactured article to be enameled along a direction of forward movement, sensor means, adapted to detect the position of the manufactured article to be enameled in relation to said orifices and by the fact that it comprises at least one command and control unit which is operationally connected to said movement means, to said sensor means and to said control means, where said command and control unit is configured to control the rotation speed of said roller around the relevant axis according to the position of the manufactured article with respect to said orifices and to its forward movement speed so as to vary the quantity and/or frequency of the enamel dispensed through the orifices themselves, i.e. the distance between two successive dispensing operations along the direction of forward movement, or to control said movement means to vary the forward movement speed of the manufactured article, the rotation speed of said roller being equal, and characterized by the fact that said roller comprises a plurality of said sets of protrusions angularly spaced apart from one another along the circular extension of the roller itself, said orifices being opened and closed in a sequential and cyclic way, i.e., with a determinate frequency, following the transit of each set of protrusions at said group of orifices defined on the container, giving rise to a substantially punctiform application on the manufactured article.
