Abstract

The covering (13) of a printing roller (10) for transferring hot glue printing material from a printing block to the front panel of a display consists of cast silicone rubber without any silicone fluid. The use of silicone-fluid-free silicone rubber ensures that the printing materials will adhere well to the panel even in a sequence of printings, because the adhesion properties of the panel will not have been reduced by silicone fluid that would otherwise have been transferred from the roller to the panel. Although the roller covering is devoid of silicone fluid as stripping agent, the printing material nevertheless separates readily from the covering, because the latter is cast and therefore has a very smooth surface.
