2. The weight-feeder control system contains an analogue-to-digital converter of the weighted value at its input. The output of the converter is connected to the digital programmable control block of the driving assembly of the mobile feed-mechanism element. Characterized in that: It consists of the block (5) for generating a programmable wave of impulses, the temporal distribution of which can be programmed, as well as the stepper motor (6) controller and the stepper motor (7). The input of the block (5) for generating a programmable wave of impulses is connected to the output of the digital programmable control system (3), while its output is connected to the input of the controller of the stepper motor (6). The output of the controller is connected to the stepper motor (7), mechanically coupled with the mobile element of the feed mechanism (4).
