APPARAT FOR BEHANDLING AV CYLINDRISKA BEHALLARE

摘要

A continuous-motion decorating machine for cylindrical containers is provided with a removable and replaceable over-varnish unit subassembly. The overvarnish unit includes control and transfer metering rolls which supply a film of varnish to an applicator roll. The latter, in turn, applies the varnish as a protective coating over decorations on the outside surface of spindle-mounted cylindrical containers. Paralleling the axes for the applicator roll and spindle is accomplished by tilting the sub-frame of the overvarnish unit relative to the main frame of the machine. Each paralleling and pressure or gap adjustment at the nips between the respective rolls, as well as at the nip between the applicator roll and container being decorated, is accomplished without upsetting adjustments at the other nips.
