In some examples, a roll unwinder for a flying roll change includes a roll station for receiving a first material roll to be unwound, and a roll station for receiving a second material roll to be unwound after a roll change has occurred. A cut-off tool can sever a first web unwound from the first material roll, and includes a pressing element, to press the web against the outer surface of the second material roll. A supporting device can be transferred from an idle state into a working state in which the supporting device supports the web to be unwound, at least at the time of the severing process. The supporting device supports the web in a web path upstream from the cut-off tool. A receiving unit at a frame that carries the cut-off tool is movably mounted in the stand of the roll unwinder.

The apparatus for combining tobacco sheets (3, 4) comprises a first shaft for carrying a first bobbin (30) of tobacco sheet (3) and a second shaft for carrying a second bobbin (40) of tobacco sheet (4). The apparatus also comprises a splicing unit (2) for combining an end portion of tobacco sheet from the first bobbin (30) to a head portion of tobacco sheet from the second bobbin. The splicing unit comprises a cutting device (20) for cutting the tobacco sheets such as to provide complementary cuts to the tobacco sheets (3) from the first bobbin and from the second bobbin (4), a dispensing device (23) for dispensing water to at least one of the tobacco sheets (3, 4), and a combining device (24) for applying force onto the tobacco sheets thereby producing a spliced tobacco sheet.

A method for cutting and connecting two bands end to end and which are at a stop, namely a first band ensuring the feed, and a second replacement band, in an unrolling machine including a cutting and connecting device including two connection assemblies arranged symmetrically with respect to a cutting and connection plane is provided. Utilizing the unrolling machine the method includes preparation of the second band, then immobilization of the bands in the plane, of simultaneous and transverse cutting of the latter, of disengagement of the cut portions not to be connected, and of end-to-end connecting of the cut portions thereof to be connected. A cutting and connecting device and a machine enabling the implementation of the method is also provided.

A device for providing a tubular foil comprises a frame (5) with a position for an active product holder (P4) from which the tubular foil (10) can be removed and at least one further position (P1-P5) for at least one subsequent product holder with a subsequent tubular foil (20). The device provides coupling means for attaching a leading end (25) of the subsequent tubular foil (20) to a tail end (15) of a spent tubular foil (10). The coupling means comprise a carriage (110) with a drivable applicator device (100). The applicator device comprises a set of opposite applicator members (130) with mutually facing operative surfaces (135) and can be manipulated between a spread position, wherein the operative surfaces lie removed from each other, and a clamping position wherein the operative surfaces lie clampingly on each other. The applicator device (100) further comprises supply means for providing adhesive strips (60) in the spread position, and can be controlled to bring the applicator members (130) with the adhesive strips (60) into the clamping position, with interposing of the tail end (15) of the spent tube (10) and the leading end (25) of the subsequent tube (20), in order to mutually connect the ends (15, 25), and to bring the applicator members into the spread position in order to release the ends with the adhesive strips.

The line comprises: an unwinding section (3) for unwinding parent reels (Ba, Bb, Bm) of web material (Na, Nb), with at least a first unwinding station (5; 7); at least a winding station (15) downstream of the unwinding section (3); a feed path from the unwinding section (3) toward the winding station (15);
The unwinding section (3) is associated with a loading arrangement of the parent reels (Bm), which comprises: an upender (253; 306) configured to upend the parent reels (Bm) positioning them with their axis horizontal; and a loading robot (263; 313), configured to position a parent reel (Bm; Ba, Bb) on an unwinding mandrel (9) of the unwinding section (3).
