The invention relates to a device for transferring a web-like material in a fiber web machine. The device includes an air connection (14) and openings (16) arranged on a wall (15) defining the air connection for forming air blows that are parallel to the travel direction of the web-like material. The device also includes a transfer surface (17) for creating a vacuum effect with air blows and thereby transferring the web- like material. The openings (16) are formed on the transfer surface (17) and the angle a between the blow direction of the openings (16) and the transfer surface (17) is 15 -30°. The invention also relates to a fiber web machine.

La présente invention concerne un dispositif pour transférer un matériau en forme de bande continue dans une machine à bande continue fibreuse. Le dispositif comprend un raccord à air (14) et des ouvertures (16) agencées sur une paroi (15) qui définit le raccord à air pour former des jets d'air qui sont parallèles à la direction de déplacement du matériau en forme de bande continue. Le dispositif comprend une surface de transfert (17) pour créer un effet de vide avec des jets d'air et ainsi transférer le matériau en forme de bande continue. Les ouvertures (16) sont formées sur la surface de transfert (17) et l'angle a entre la direction de jet des ouvertures (16) et la surface de transfert (17) est 15 à 30°. La présente invention concerne également une machine à bande continue fibreuse.
