Bar-code label applicable for bar-code controlled manufacturing including painting process and production method therefor

A device for preparing a barcode label with a plurality of identical first slots and identical second slots, which first and second slots are of different sizes and are arranged on the label to form a bar-code pattern, said bar-code pattern representing specific binary data, comprising:

• a first punch means for forming said first slots in said blank label, said first punch means being installed in a first station at which said first slots are formed;
• a second punch means, provided at a second station at which said second slots are formed, for forming said second slots;
• a holder means for firmly holding said blank label during the bar-code encoding operation, said holder means being movable between said first and second stations;
• a first actuator associated with said holder means for driving the latter to hold said blank label;
• a second actuator associated with said holder means for moving the latter between said first and second station;
• and a controller associated with said first and second punch means and said first and second actuator for controlling operations thereof, said controller adapted to receive a signal indicative of said specific binary data and converting the specific binary data into the bar-code pattern to be encoded in the blank label, and said controller outputting control signals to said punch means and said actuators for controlling the operations thereof according to the determined bar-code pattern.
