 Technical Data: Orbiter™ Rotary Pad Roll-Off Device  Available for all three sizes of RedStar Multicups: 60, 90 and 130mm. Best for applying thick, heavy images, using typical cupslide clichés. Plates may be steel foil, thick steel or temporary plastic plates, etched to maximum depth, if necessary. Multiple hits possible. Unit available for installation on the Orion 130 pad printer only. Ask your representative for details on how it can be adapted to your product decorating application.  Above: low angle view of machine front showing part shuttle with Orbiter device above.

Rotary Pad Roll-Off-- Patent Pending:
Orbiter™ Device Extends Orion's Range
AN INNOVATIVE accessory can now be fitted to the Orion 130
pad printer to enable decorating products with large, bold images up to 10 inches long and 3.5 inches wide. The device, named Orbiter™, uses a rotary silicone rubber padroll to transfer an ink image to a flat or cylindrical part from a steel foil cliché plate.
The Orbiter concept (patent pending), allows pad printing of a thicker layer of ink than would normally be applied with conventional pad transfer methods. The result is a more opaque and consistently even image with a single hit.
By working in tandem with the standard Trans Tech cupslide accessory fitted with a 130mm RedStar MultiCup ink cup, the Orbiter picks up the image from a magnetically mounted 150 x 810mm foil plate, then moves forward to the printing position. The padroll, measuring 100mm in diameter by 100mm wide, is pneumatically actuated to rotate to its home position before transferring the image to the part.
Above: a typical installation of Orbiter on Orion 130, showing safety guarding and manual part shuttle.
Advantages and Benefits:
Additional benefits of the technique are the smooth rotary laydown which eliminates issues associated with pad tip placement, allowing a usable image area of up to 3.5 inches width on a 4-inch padroll. The rolling transfer action also eliminates any ink being pushed outside the intended image area caused by compressing a large, conventional pad.
Another plus: with such a wide image, using a conventional pad would require a much larger, oversized pad to compensate for distortion. The associated higher cost of a large pad is avoided by using the less expensive rotary padroll.

The 100mm diameter Orbiter device allows printing on either flat parts, or cylindrical products with less than 3.5 inches diameter. A manual part shuttle is recommended for loading and unloading parts into the printing area. Cylindrical parts would also require a suitable, rotating mandrel fixture to allow the part to roll while accepting the image from the padroll.
Potential applications using semi- or fully automated systems are available on request. Ask your Trans Tech representative for more details.
