Tube or tubular pack painting by machine, uses second brush spaced from first to apply second coat non-overlappingly adjoining first and available for code printing

摘要

At the same time as the first coat is applied to the tube (2) by the first brush, a second coat is applied (4) to adjoin but not overlap the first by a second brush spaced from the first brush, but at the same painting position. The two brushes diametrically oppose one another in relation to the axis of the pin or spindle on which the tube is rotating. The painting machine has spindles or pins with their free ends distant from the machine rotor or table on which they are mounted. Bar or line code (5) is printed onto the second coat (4) once this is dry.
