ABSTRACT:
A special-purpose clutch incorporated in a drive mechanism of hot stamping apparatus wherein heated type on a rotary type carrier is periodically pressed against a printing ribbon in superposition on a continuous strip of plastics or other material being fed at constant speed over a platen, thereby imprinting characters on the strip at constant spacings. The clutch comprises a drive disk mounted on a motor output shaft, a driven disk mounted on a type carrier shaft, and a spring through which rotation is normally imparted from the drive to driven disk. The spring is yieldable to permit the driven disk to be rotated, while the heated type is being pressed each time against the printing ribbon, by the strip of material at lower speed than the drive disk. The angular speed of the type being pressed against the ribbon can thus be precisely synchronized with the linear speed of the strip traveling over the platen.
