Abstract: Methods and apparatus for applying a flying splicing tape to a roll of sheet material. A preferred embodiment of the invention provides methods and apparatus for lifting a portion of the outer-most layer of sheet material away from a roll of sheet material to form a lifted portion of the outer-most layer, applying a splicing tape to a wound portion of the roll, and applying pressure to the lifted portion of the outer-most layer to progressively place the lifted portion of the outer-most layer in contact with the remainder of the roll and the splicing tape.

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 source for supplying lengths of adhesive tape applies such adhesive elements with their outer surfaces facing outwards onto a gripping element consisting of a rotating drum. The drum in question applies the adhesive element on the outer surface of a reel of web material in such a way as to establish adhesive connection with the latter. As a result of a subsequent movement of the drum with respect to the reel, there is formed a loop of web material. Since the loop is separate from the reel, it can undergo a cutting action with the consequent formation of a free flap that can be used for unreeling the web material from the reel. After the web material has been unreeled for a certain stretch and the portion on which the aforesaid adhesive element was applied has been eliminated, on the same web material there may be applied a further adhesive element which is left uncovered for at least part of its surface provided with adhesive.

Abstract: A method and apparatus for automatically applying a flying splicing tape to a roll of sheet material. The roll of sheet material is defined by a width and includes an outer-most layer. With this in mind, the method includes lifting a portion of the outer-most layer away from a remainder of the roll. The lifted portion is then cut to form a leading edge that is otherwise spaced from a remainder of the wound roll. To this end, the cut is made at a defined spacial location along the outer-most layer such that the leading edge is radially aligned with a defined application line relative to a circumference on the wound portion of the roll. In other words, when the outer-most portion is subsequently wound back onto the roll, the leading edge will be aligned with the defined application line. The splicing tape is then applied to the wound portion of the roll at the defined application line, such that the splicing tape extends across at least a portion of the width of the roll.

Abstract: An automatic tape crossover machine having two feeding mechanisms to supply running and new tapes, respectively. A powered cutter is provided through which the running tape is to pass and be cut in response to a cut signal, where the cutter is positioned downstream of the first tape feeding mechanism. The machine also includes a joining mechanism at which a portion of a new tape is to be joined to the running tape in response to a join signal.
