The invention relates to a device for conveying and guiding a lead-in strip in a paper machine, which device comprises a conveyor belt (20) which is permeable to air and in whose connection devices (15) are fitted by whose means a vacuum effect can be produced on the run (20A) of the conveyor belt (20) on which the lead-in strip is conveyed, by means of which vacuum effect the lead-in strip is made to adhere to and kept in contact with said run (20A) of the conveyor belt (20). On said conveying run (20A) of the conveyor belt (20), on the opposite side of the conveyor belt (20) in relation to the lead-in strip, a foil rib/ribs (15) is/are fitted, by whose means said vacuum effect is produced on the conveying run (20A) of the conveyor belt (20).
La présente invention concerne un dispositif d'entraînement et de guidage de l'amorce dans une machine à papier. Ce dispositif comprend une bande transporteuse (20) perméable à l'air. L'ensemble est équipé de dispositifs (15) qui sont en contact de cette bande et qui produise une dépression au niveau du chemin (20A) de la bande transporteuse (20) sur lequel l'amorce est transportée. Cette dépression fait adhérer l'amorce sur la bande transporteuse et la maintient en contact avec le chemin (20A) de la bande transporteuse (20). Sur ce chemin d'entraînement (20A) de la bande transporteuse (20), de l'autre côté de la bande transporteuse (20) par rapport à l'amorce, on a adapté des nervures en feuille (15) grâce auxquelles l'effet de dépression se produit au niveau du chemin d'entraînement (20A) de la bande transporteuse (20).
