GP/4 Semi-Automatic Decorator | Strutz International, Inc.

The GP/4 is no longer in production. These specifications are preserved as part of our product history.

The GP/4 semi-automatic screen decorator was specifically designed for simple, efficient operation. It is microprocessor controlled to ensure consistent operation for flat, round and oval shaped containers.

The GP/4 is gear driven to facilitate positive drive action. However, there are no drive gear changes required to match bottle and gear pitch diameters, as is required in competitive machines. This feature saves time and money, and eliminates the need to stock additional gear components.

The GP/4 screen stroke adjustment is simple and accurate. A unique Strutz innovation automatically matches the parametric distance of each container with the linear stroke of the screen to ensure precise tracking. Manual adjustment of the container-screen tracking for various container sizes and shapes is unnecessary. Simple changeovers are required for flat and oval container shapes, but require few tools.
