  • Decal transfer device
    Patent number: 4874454
    Abstract: A device is shown for transferring sublimation decals to curved substrates such as the surfaces of ceramic mugs. The device employs a flexible transfer head which comprises a supported, flexible electrical heating pad which is made to envelop and press against the surface of the article onto which the decal design is to be transferred. The pad is then electrically heated, causing the sublimation dyes on the decal interposed between the pad and the surface of the article to be transferred from the backing sheet of the decal to the article's surface.
