ABSTRACT:
A slender ribbon currently in use and nearing depletion is spliced automatically with a similarly slender new ribbon, held motionless and ready to feed as the replacement for the ribbon in use, by a device comprising a pair of jointing rollers positioned in symmetry on opposite sides of the two ribbons and disposed normally in a standby configuration, stationary, which allows the ribbon in use to pass freely between their two peripheral faces whilst the leading end of the new ribbon is restrained by one of the rollers and distanced from the ribbon in use through the action of an adjacent pulley; in a second configuration, the two rollers contrarotate synchronously and in a direction concurrent with the feed direction of the ribbon in use, completing one full revolution during which the new strip is accelerated initially by the restraining roller to a feed velocity matching that of the ribbon in use, whereupon the two ribbons are sandwiched between two stickers and pinched tight.
