IPC: B41M5/382
Filed: 1986-05-21
Abstract: PURPOSE:To enable transferring free of disorder of tones, by cutting up a heat- sensitive ink by a transfer roll and transferring the cut-up ink as a series of dots. CONSTITUTION:The peripheral surface of an engraved roll 11 is provided with V-shaped grooves 10 inclined relative to the axial direction. The peripheral surface of a first transfer roll 15 is provided with grooves 19 having a shape similar to that of the grooves 10 and an inclination reversed to that of the grooves 10 in a required pattern area. An excess of a heat-sensitive ink supplied to the engraved roll 11 from a hopper 14 by supplying rolls 12 is raked away by a blade 13. With the roll 11 rotated, the ink contained in the grooves 10 is transferred to the roll 15. At this time, the ink is cut up, and is transferred into the grooves 19 as a series of dots. Thus, the ink is transferred only onto the pattern area as a set of dots. Thereafter, the ink is transferred onto a second transfer roll 16, and is then transferred to an object 17 to which an image is to be transferred. Thus, the ink is in the form of dots on a transferring surface, whereby uniform transferring can be achieved.
