Abstract
A frictional clutch for a correction device includes a rotatable supply reel with a circular center opening and a rotatable take-up reel being laterally arranged spaced apart from the supply reel, the take-up reel having an outer circumferential surface onto which a correction tape is to be wound up and the supply reel having an outer circumferential surface from which the correction tape is to be wound off, wherein the outer circumferential surface of the supply reel is provided with a circumferential radial groove in which an elastic tensioning element is accommodated, the radial circumferential groove being at its bottom at least partially transected such that the elastic tensioning element projects into the center opening secantically, when it is in a stress-relieved condition.
