A machine for imprinting on a strip or sheet comprises multiple printing cylinders in tandem and revolving continuously at the same speeds for imprinting successive impressions on the strip. The strip is intermittently fed at a linear speed that is the same as the peripheral speed of the impression surfaces of the printing plates on the printing cylinders. The mechanism for intermittent feed comprises a carrier having spring fingers that engage notches at the sides of the strip to feed the strip a predetermined amount after which the carrier is returned to an initial or starting position for again feeding the strip.
