METHOD AND APPARATUS FOR HOT-MELT PRINTING

摘要

A rotary screen printing system is provided for printing hot melt dots and patterns on labels and various types of containers (51). A circular or cylindrical screen (10) is manufactured with the required pattern, and hot-melt material is delivered to the interior of the screen (10). Multiple patterns may be provided around the cylinder, depending on the size of the cylinder and the label for one container (51). A step action servo motor (20) coordinated with the advance of the product label or container (51) causes the screen (10) to contact the container (51) and rotate through the pattern, to screen the required pattern of dots on the surface of the container or label (51).
