Abstract

L'invention concerne un appareil à river (1) comprenant un serre-flan (3) et une bouterolle (4). Le serre-flan (3) et la bouterolle (4) sont entraînés par voie hydraulique à l'aide d'un piston de serre-flan (12) et d'un piston de bouterolle (13). Pour perfectionner de façon avantageuse un appareil à river (1) du type susmentionné, le piston de serre-flan (12) et le piston de bouterolle (13) sont actionnés par la même pression hydraulique, la surface efficace (36) du piston de serre-flan (12) étant plus petite que la surface efficace (14) du piston de bouterolle (13).
