In the web splicing device, the following end of the first roll of web is cut and is then drawn to and held on the hold surface of a butt splicing table. The leading end of the second web roll is cut on a provisionally positioning table to the shape of the following end of the first web roll, is then carried to the butt splicing table by a carrying device and is butt spliced to the following end of the first web roll.
