Abstract
A wheel (15) is freely mounted on the shaft (2) of a printing head and is in contact at its periphery with a film which is to be printed. A tachymeter (10) is provided which detects the speed of rotation of the wheel (15) and transmits a corresponding signal to apparatus (26) for controlling the speed of rotation of the motor (8).
