Abstract
959,402. Thermographic copying. ITEK CORPORATION. Dec. 12, 1960 [Nov. 21, 1960], No.42631/60. Heading G2C. Copies are made on heat-sensitive copy sheets by irradiating an original having infra-red absorbing markings and placing the irradiated original in heat-conductive relation with the copy sheet, the irradiation of the original being of an amount to produce heating sufficient to form an image when placed against the copy sheet. Either or both of the original and copy sheets may be opaque to infra-red e.g. comprising metal base layers. Preferably the copy sheet is preheated below the image-forming temperature which preferably is not below 75‹C. before contacting the irradiated original. If desired the copy sheet may carry separate heat-sensitive layers on its opposite surfaces and two different copies made on the opposite sides. As shown, an original 160 is fed by a roller 164 along the outside of a housing 168 in which is disposed a lamp 176 and a heat-sensitive copy sheet 184 is brought into contact with the irradiated original by a roller 192. Alternatively (Fig. 2, not shown) the original and copy sheets may be drawn over curved guides by a pair of gripping rollers, the lamp being arranged between the back of the copy sheet guide and the front of the guide for the original.
