The invention concerns a device wherein the bars (13) are arranged in bulk in the container (5). The mobile frame (17) of the grasping mechanism (14) moves forward such that the jaw (24) can seize a bar by its middle part and remove it in position (13a) while the trolleys (37) move away from the rail (36) so that the rollers slide on the rods (43), gradually lift the whole bar and bring it to rest on the receptacle (16). The shaft (49) is then driven in rotation so that the racks (47) and the support plate segments (46), which form the receptacle (16), move upwards and the bar (13) drops in the supply channel (8) where it is hooked to the bar clamp of the bar-pusher which drives it axially into the turning center control members.
