ABSTRACT:
An arrangement for transferring a ribbon from a feed spool to a take-up spool comprises a pair of electric motors each one connected to a corresponding spool for the rotation thereof. The motor connected to the take-up spool is supplied by a constant current generator so as to wind-up said ribbon with a minimum and substantially constant torque. The motor connected to the feed spool is supplied by a constant voltage generator so as to keep said ribbon constantly taut during the transferring thereof. A changeover device alternates the function of the two spools when the ribbon is fully wound on the take-up spool.
