Abstract
A production device (4) comprising: a stretching rod (14); a first valve (30) movable between an open position and a closed position; at least one second valve (36) movable between an open position and a closed position. The first control device (32) is actuated as a function of a position signal of the tension rod (14), and the second control device (38) is actuated as a function of a time signal as a function of a first predetermined time elapsed since a state change of the first valve (30) between the closed position and the open position.
