Abstract
The invention relates to a process and to a machine for splicing the trailing end of a running expiring web (e.g., a web of cigarette paper) to the leading end of a fresh web while the ends of the webs travel next to each other, in the same direction and at an at least substantially identical speed between a rotary knurling surface and a complementary second rotary surface which may but need not be a knurling surface. The rolls which constitute or mount the carriers for the two surfaces are driven in such a way that each n-th (e.g., each tenth) revolution results in the making of a splice between the leading and trailing ends of the webs. The forwardly and/or rearwardly extending remnants of the fresh and expiring webs are torn off the spliced-together webs at the respective ends of the splice.
