The apparatus for combining tobacco sheets comprises a first shaft for carrying a first bobbin of tobacco sheet and a second shaft for carrying a second bobbin of tobacco sheet. The apparatus also comprises a splicing unit for combining an end portion of tobacco sheet from the first bobbin to a head portion of tobacco sheet from the second bobbin. The splicing unit comprises a cutting device for cutting the tobacco sheets such as to provide complementary cuts to the tobacco sheets from the first bobbin and from the second bobbin, a dispensing device for dispensing water to at least one of the tobacco sheets, and a combining device for applying force onto the tobacco sheets thereby producing a spliced tobacco sheet.

Apparatus suitable for guaranteeing a quick and automatic change of materials wound on reels, said apparatus consisting mainly of a reel-alternating mechanism combined with a mechanism for cutting and reconnecting the reeled material.

A winder applied can include a turret part configured to hold a running film roll and a standby film roll, and a leading part including a head part configured to sense a finishing tape attached to an end side of a thin film wound on the standby film roll, grip the finishing tape, and remove the finishing tape from the standby film roll. The head part can include a head body part, a sensing unit disposed on the head body part, and a tape adsorption part disposed on the head body part. The tape adsorption part may be configured to move to a position of the finishing tape sensed by the sensing unit, temporarily couple to the finishing tape, and remove the finishing tape from the end side of the thin film wound on the standby film roll. The sensing unit may be configured to sense the finishing tape.

A method for splicing two sheets of material is provided, including: providing a processing line including a splicing head and a quality sensor located between upstream and downstream ends of the processing line; providing first and second sheets of material; processing the first sheet on the processing line along a processing direction from the upstream end towards the downstream end; detecting, by the quality sensor, a value of a quality parameter at a detected portion of the first sheet; and, when the value falls within a predetermined threshold, transporting the first sheet along the processing line such that the detected portion is located prior to getting into the splicing head from the upstream end, and splicing the first and the second sheets at the splicing head when the detected portion is located prior to getting into the splicing head from the upstream end.
