An intermittently operated apparatus for decorating cylindrical cans, each can having a cylindrical surface and a rim, includes a rotatable mandrel wheel; a plurality of mandrel assemblies mounted on the mandrel wheel which hold the cans on the mandrel wheel; a surface applicator roll having a length which extends past the bottom of each can and which applies a coating of varnish to the cylindrical surface of each can; a supply assembly for supplying the varnish to the surface applicator roll; a freely rotatable rim applicator roller having a tapered surface positioned in contact with the bottom rim of each can and with that portion of the surface of the surface applicator roll that extends past the bottom of each can, such that the rim applicator roller is driven by the surface applicator roll and varnish is transferred from the surface applicator roll to the tapered surface of the rim applicator roller and then to the bottom rim of each can at the same time that varnish is applied by the surface applicator roll to the cylindrical surface of each can; and a support and adjusting assembly for supporting and positioning the rim applicator roller with respect to the bottom rim of each can and the surface of the surface applicator roll so as to adjust the pressure of the rim applicator roller on the surface applicator roll and to adjust the pressure of the rim applicator roller on the bottom rim of each can.
