18 Abstract of the Disclosure An intermittently operating unwinding apparatus has a splicing unit with a cross-member which is movable against this at right angles to the web expiring from a winding roll. With a separating device positionable from the other web side against the cross-member, the web is separated by lifting the empty spool mounted in an unwinding apparatus out of its unwinding position. A new parent roll whose web beginning is provided with an application of adhesive is transported by means of a conveyor to the point of the empty spool and the web beginning position relative to the splicing unit. The splicing unit holding the separated web end at the cross-member is, with respect to the axle of the new parent roll, movable against this in radial direction, where the web end meets the beginning of the web and is attached by means of the application of adhesive. The web length required to lead the web end to the new roll is made ready by a dancer roller.
