Abstract
A rotation elastic damped cutting device of a slitting cutter with at least one cutting wheel and a driven shaft for driving the cutting wheel, allows absorption of an abrupt, shockproducing blocking force. A rotation elastic dampener is provided in a radial space between the driven shaft and the cutting wheel as a cylindrical bushing. The cutting wheel and the driven shaft are connected by at least one wall, respectively, and the elastomer is vulcanized on one of these walls. A circumferentially fixed metal sleeve is inserted between the elastomer and the other wall for causing a radial pressure on the elastomer, effecting a good friction grip between the elastomer and the metal sleeve.
