Abstract (en)

[origin: EP0727315A2] There is provided a simply applicable printing method for a letter printing on a film in a packaging machine which makes sealing as it changes transfer velocities of a letter printing object. A transfer velocity of a packaging film (8) is detected by a rotary encoder (7). A carbon tape (2) unwound from a carbon tape roll (1) and the packaging film (8) are placed between a head supporting platen roller (6) and a line thermal head (5) and a necessary printing is made on the packaging film (8). An electric supply to the thermal head (5) is controlled synchronously with the transfer or moving velocity of the packaging film (8) detected by the rotary encoder (7). <IMAGE>
