The invention relates to a splicer for webs (9', 9") of packaging material wound onto bobbins for packag- ing machines having a device (10) for feeding a free end of a web (9') of packaging material to a finishing web (9") of packaging material, a knife (33) for separating the finishing web (9") of packaging material after splicing and an apparatus for joining the two webs (9', 9") of packaging material. For splicing at full speed, a disc (20) is provided, which is rotatable about an axis (19) and bears a circular-cylindrical segment (21) which can be rotated independently about the axis (19) and a counter-element (22) which is fixed in relation to the disc (20) and holds a knife (27) for separating an end of the web (9') of packaging material remaining free, which segment and counter-element can be moved from a pivoted- apart position into a clamping position in relation to the free end of the web (9') of packaging material, nipping rollers (31', 31") by means of which the finish- ing web (9") of packaging material is guided being arranged on the pivoting circle of the circumference of the circular-cylindrical segment (21), and the device (10) for feeding a free end of a web (9') of packaging material being a web-material gripper which can be guided through the gap between the circular-cylindrical segment (21) and the counter-element (22) in their pivoted-apart position.
