<p>The device for the quick splicing of two paper webs comprises a pair of conveying roller for feeding both webs in overlapping relationship at the same speed, a rotary blade, arranged downstream of the conveying rollers, for cutting simultaneously both overlapping and running webs, two discarding spools, arranged one on each side of the path of the running webs, for removing a severed portion of one of the webs, a splicing roller, positioned on the same side of the rotary blade, with respect to the path of the running webs, and finally a pair of drawing rollers, for drawing the web which has been spliced at the same speed as the conveying rollers. The rotary blade is mounted on a roller-like supporting element, and on this supporting element there is provided, immediately after the blade in the direction of rotation of same, a trough-shaped longitudinal suction groove, which has the purpose of removing the cut leading end of a web from the path of the running webs, during an operational phase of the splicing device. The suction groove is selectively connected to a suction source.</p> |
