Abstract (en)
[origin: ES487054A1] In a high speed printer, apparatus is provided for rotatably driving a ribbon take-up reel and a ribbon supply reel, each reel being adapted to support a portion of an inventory of ribbon running from the supply reel to the take-up reel at a constant speed differential between reels. This apparatus comprises a first inelastic drive belt for peripherally non-slip driving the ribbon portion on the take-up reel and a second inelastic drive belt unattached to the first drive belt for peripherally non-slip driving the ribbon portion on the supply reel. Means are provided for driving the first belt at a constant selected speed and drive coupling means provided which are non-slip driven by the first belt and are for non-slip driving the second belt at a constant speed which is slower than the first belt. In this manner, the web or ribbon between the supply reel and the take-up reel is maintained under a constant uniform strain level.
