Abstract: The leading end of a running fresh web of cigarette paper or the like is spliced to the trailing end of a running expiring web while the ends travel at the same speed, in the same direction and next to each other. The splicing unit includes a rotatable roll at one side of the path for the advancing ends, and a rotary carrier at the other side of such path opposite the roll. The carrier is provided with a segment having a convex knurling surface which cooperates with the peripheral surface of the roll to provide the webs with a splice while the segment engages the adjacent web. Prior to splicing, the carrier is rotated in a first direction to move the segment away from the path for the webs, and such movement is followed by rotation of the carrier in a second direction to accelerate the knurling surface at least close (a) to the common speed of the webs and (b) at least close to the speed of the peripheral surface of the roll.

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.

Abstract: A tail for adhering the tailing edge of a first roll of tape that is being fed to an application device to the leading edge of a second roll of tape without stopping the tapes includes a bulge which is located in the tail and has an adhesive coating on each side. A first protective element located on the tail releasably covers the adhesive coating on one side of the bulge and a second protective element located on the other side of the bulge releasably covers the adhesive coating on the other side of the bulge when the tail is wrapped onto a roll base. The leading edge of the second roll of tape is wrapped around the tape from the first roll to form a loose knot and then is threaded through a pair of pincher rollers through which the first roll of tape is fed. Thus, when the bulge passes through the pincher rollers it becomes adhesively attached to the leading edge of the second roll and the knot is tightened around the second roll and a mechanical joint is formed between the tapes.

Abstract: The present invention features a web feeding and transition assembly for exchanging a first, used, web roll for a second, fresh, web roll, so that web material will be continuously conveyed along a web-conveying feed path. Each web of the first and second web rolls includes a backing or a separate, interleaved web. The transition assembly has a first mounting for allowing the first web roll to unwind and feed the first web to the feed path. A second mounting adjacent the first mounting allows the second web roll to unwind so that the second web may be spliced to the first web. A "bump splicing" unit causes an adhesive section of the second web to contact an end portion of the first web, as the first web roll runs out. Thus, a continuous web feed is accomplished by splicing the first and second webs "on the fly"; the new, incoming roll is caused to match the speed of the expiring roll within one revolution.
