The invention relates to a device which is used to produce core packets, especially for casting engine blocks and cylinder heads, comprising a shooting station (1) wherein individual cores are shot, and a receiver station (2) wherein the shot cores are received and are transferred in order to form packets on an assembly line (3). A shooting cap (7) comprising a sand store (5) provided with a shooting plate (6) and a shooting head (8) is associated with the shooting station (1) of a preferably two-part tool (4). The invention is characterised in that several tools (4) are arranged in order to shoot different cores on a revolving table (9) such that by rotating the revolving table (9), the tools (4) are brought together inside the shooting station (1) and are transferred from the shooting station (1) together with the shot cores into the receiving station (2).

L'invention concerne un dispositif de fabrication de paquets de noyaux, notamment de coulée de blocs moteur et de têtes de cylindres, comportant une station de soufflage (1) dans laquelle des noyaux individuels sont soufflés, et une station de prélèvement (2) dans laquelle les noyaux soufflés sont prélevés et transportés vers une ligne de montage (3) pour la mise en paquets. Un capot de soufflage (7) comportant un réservoir de sable (5) pourvu d'une plaque de soufflage (6) et d'une tête de soufflage (8) est affecté à un outil (4) de préférence composé de deux pièces, dans la station de soufflage (1). Le dispositif selon l'invention est caractérisé en ce que plusieurs outils (4) de soufflage de noyaux différents sont disposés sur un plateau tournant (9) et en ce que la rotation du plateau tournant (9) permet d'amener les outils (4) dans la station de soufflage (1), les uns après les autres, et avec les noyaux soufflés, de la station de soufflage (1) à la station de prélèvement (2).
