17 Abstract of the Disclosure An intermittently operating unwinding apparatus has a separating device with which a web end is formed on the lifting out of an empty spool from the guide ways of an unwinding unit. A holding device holds the web end in a plane which extends parallel to the guide ways, on which a new winding roll located in waiting position rests with its roll axle. The machine has a splicing unit with a cross-member arranged parallel to the guide ways to which the beginning of the web of the new parent roll can be joined. During transport of the new parent roll out of the waiting position into its unwinding position, the splicing unit is moved by dogs engaging the roll axle against the holding device and the web beginning is joined to the web end.
