Cette bobine comporte deux flasques dont l'un est moulé d'une seule pièce avec un noyau et l'autre rapporté et fixé sur l'extrémité libre du noyau. Ce dernier comporte une paroi cylindrique extérieure 8 et une paroi cylindrique intérieure 9 de laquelle font saillie vers l'intérieur plusieurs nervures 6 destinées à s'enclencher avec une broche d'un enregistreur à bande vidéo. Une encoche il est réalisée dans la paroi 9, en arrière de chaque nervure 6, afin de donner à cette paroi 9 une épaisseur uniforme sur toute son étendue. Domaine d'application : enregistreurs à bande vidéo en cassettes.A reel for cassette tape is disclosed. This coil has two flanges, one of which is molded in one piece with a core and the other attached and fixed to the free end of the core. The latter has an outer cylindrical wall 8 and an inner cylindrical wall 9 from which protrude inwardly several ribs 6 intended to engage with a pin of a video tape recorder. A notch is made in the wall 9, behind each rib 6, in order to give this wall 9 a uniform thickness over its entire extent. Field of application: videotape recorders in cassettes.
