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.

The invention relates to a splicer assembly for splicing material webs. The splicer assembly comprises a first dispensing device for dispensing a finite first material web, a second dispensing device for dispensing a finite second material web, a connecting device for connecting the finite first material web and the finite second material web so as to form an endless material web, and a material web threading assistance assembly for assisted threading of the finite first material web or of the finite second material web into the splicer assembly in a threading procedure. The material web threading assistance device comprises at least one conveying installation for conveying the finite material web to be threaded in a threading direction in the threading procedure, and a conveying installation drive installation for driving the at least one conveying installation in the threading procedure.

A slitter-winder for fiber webs has an unwinding section (10), a slitting section (20) and a winding section (30) and is configured to unwind, slit and wind a thick fiber web having a basic weight of at least 200 g/m.sup.2 to customer rolls (33). The unwinding section (10) has a first unwinder (11) and a second unwinder (12) for unwinding the thick fiber web from a parent roll of full-width thick fiber web (W11, W12), and a joining device (16, 17) for joining a beginning end of a thick fiber web (W11) coming from a parent roll in the first unwinder to an end of a thick fiber web (W12) coming from a parent roll in the second unwinder by forming a joint (J). The winding section (30) has a cutting device (35) for cutting and removing joint part(s) of the thick fiber web from the winding section (30).

A method for splicing a material associated with an absorbent article, including: transporting the material in a direction of transport with a material wound around an entrance roll and a moving roll of a dancer unit; splicing a subsequent material with a preceding material which is a material being transported, by bonding a leading end portion of the subsequent material with the preceding material; and cutting the preceding material so that the total length of a bonded portion and an stacking portion is larger than a path length of the material from a downstream end of a winding portion of the material that is wound around the entrance roll to an upstream end of another winding portion of the material that is wound around the moving roll positioned at a reference position.
