Disclosed are a method and an apparatus for joining the discharged final section (3) of a first web of material (1), which extends across a web- processing machine on a horizontal transport level (T) along a horizontal direction of travel (t), to the delivered initial section (4) of a second web of material (2) located in a supply zone (27). A draw-in mechanism (9) is provided in which a final section (3) of the first web of material (1) that is embodied as a loose end is retained horizontally at the end. Said draw-in mechanism (9) is provided with a joining device (10) below the transport level (T). The joining device (10) can be moved parallel to the direction of travel (t) and is used for connecting the final section (3) in a tension-proof manner to the initial section (4) that contacts the final section (3) in a planarly overlapping fashion. According to the invention, the initial section (4) is contacted in a planarly overlapping fashion with the final section (3) by means of a vertical movement component of a pretensioning mechanism (8) relative to the draw-in mechanism (9).
L'invention concerne un procédé et un dispositif pour relier la section terminale (3) d'une première bande de matière (1) se déroulant, laquelle s'étend sur un plan (T) de transport horizontal dans un sens (t) de transport horizontal sur une machine d'usinage de bandes, avec la section initiale (4) arrivant d'une deuxième bande de matière (2) se trouvant dans une zone de réserve (27). Selon l'invention, un dispositif d'insertion (9) sert à tenir à l'horizontale l'extrémité de la première bande de matière (1) au niveau d'une section terminale (3) formant une extrémité libre. Le dispositif d'insertion (9) est équipé, sous le plan (T) de transport, d'un dispositif de raccordement (10) mobile parallèlement au sens (t) de transport pour raccorder de manière résistante à la traction la section terminale (3) à la section initiale (4) en superposition plane sur ladite section terminale (3). L'invention est caractérisée en ce que la section initiale (4) est placée en superposition plane sur la section terminale (3) par un mouvement vertical du dispositif de précontrainte (8) relativement au dispositif d'insertion (9).
