Abstract

An apparatus for thermographic series-duplication of an original bearing heat radiation-absorbent indicia comprises a rotary drum having means for mounting the original on a first imprint of the external surface thereof, at least one source of infrared radiation mounted outside the drum for successively irradiating the original during the rotation of the drum, a first roller for pressing a web coated with a fusible dye into temporary contact with the original subsequent to its irradiation to cause the original to pick up dye from the web in accordance with its heated indicia pattern, and a second roller for pressing a copy sheet into temporary contact with the original subsequent to its contact with the coated web to cause the copy sheet to pick up an impront of the dye image from the original, the drum being adapted to start and stop in a predetermined angular position in which said source of infrared radiation with irradiate a second part of the external surface of the drum which is spaced from said first part thereof in a manner to prevent excessive heat transfer between the two parts.
