A device for splicing and continuously providing an outgoing film web includes a splicing unit for splicing a first or a second incoming film web to the outgoing film web, and a clamping unit and an intermediate film storage for the outgoing film web. The splicing unit includes a first sealing jaw with a first holding device for the outgoing film web, and a first cutting device for severing the outgoing film web in the region of the first sealing jaw. The splicing unit includes a second sealing jaw with a second holding device alternately for the first or the second incoming film web, and a second cutting device for severing this incoming film web. The sealing jaws with their respective holding devices can be displaced relative to one another out of the region of action of their first and second cutting devices into their mutual region of action.
