Abstract

Dispositivo atto a guidare, in modo sicuro nella direzione desiderata, nella fase iniziale di lavoro di una machina piegatrice di fogli, il lembo anteriore di un foglio (1) da ripiegare più volte su se stesso a fisarmonica, presentante, parallelamente al percorso (2-3) di avanzamento in rettilineo del foglio da ripiegare, in corrispondenza del gruppo (4, 5) di avanzamento del detto foglio, un mezzo (6) a lamine, elasticamente flessibili, in posizione adiacente al foglio (1). Tale mezzo a lamine (6) assume due posizioni, una posizione attiva nella quale il mezzo a lamine viene fatto avanzare nel punto di uscita del foglio dal percorso di avanzamento (2-3), l'estremità (15) del mezzo a lamine in corrispondenza di tale punto di uscita del foglio (1) essendo incurvata, con memoria di forma della curvatura, nella stessa direzione in cui deve essere deviato il lembo anteriore del foglio per guidare quest'ultimo verso un elemento piegatore (10, 7), ed una posizione inattiva o di riposo in cui il mezzo a lamine (6) viene riportato nella posizione rientrata iniziale in modo tale che la parte ricurva (15) del mezzo a lamine (6), non ostacoli i movimenti del foglio nella fase di piegatura dello stesso.(Figura 1).Device designed to guide the front edge of a sheet (1) to be folded several times on itself with an accordion, presenting, parallel to the path (2) in the initial work phase of a sheet folding machine -3) for feeding the sheet to be folded in a straight line, in correspondence with the group (4, 5) for feeding said sheet, a means (6) with elastically flexible sheets, in a position adjacent to the sheet (1). This sheet means (6) takes two positions, an active position in which the sheet means is advanced at the point of exit of the sheet from the feed path (2-3), the end (15) of the sheet means in correspondence of this exit point of the sheet (1) being curved, with shape memory of the curvature, in the same direction in which the front edge of the sheet must be deflected to guide the latter towards a folding element (10, 7), and an inactive or rest position in which the sheet means (6) is returned to the initial retracted position so that the curved part (15) of the sheet means (6) does not obstruct the movements of the sheet in the folding phase of the itself. (Figure 1).
