ABSTRACT:
A sublimation transfer device for mugs that consists of a cuff lined with multiple layers of material designed to improve the uniformity of the pressure and temperature distributions over the transfer surface. The cuff comprises a metallic support band with two ends that are wrapped around the mug and pushed toward each other to tighten the cuff's grip and increase the pressure exerted on the outside surface of the mug. The tightening of the band is effected by a double-source tensioning force that increases the uniformity of the pressure and temperature distributions. The interior surface of the cuff is first lined with a layer of variable-density foam, having heavier foam at the edges and lighter foam at the center, which under pressure conforms more precisely to the surface of the mug than uniform-density foam. A high-temperature electrical-heater tape is then attached to the inside surface of the foam and is lined with a heat-distributing metallic foil coated with Teflon.RTM. similar nonstick material. The device is also provided with a mug positioner designed to optimize the pressure distribution over the transfer surface during the tensioning of the cuff.
