The label is attached to the packaging container, and the deviation between the center line of the label and its theoretical position is within the specified range, which is called a positive standard. Where there are multiple labels on the same packaging container, the deviation from the theoretical position shall be determined according to the above definition, and shall be within the specified range.

The beginning of the work process is that the box is fed to the labelling machine at a constant speed on the conveyor. The mechanical fixture separates the boxes by a fixed distance and pushes the box in the direction of the conveyor. The mechanical system of the labeler includes a drive wheel, a labeling wheel, and a reel.
The drive wheel intermittently drags the label belt to move, the label tape is pulled out of the spool, and the label wheel is pressed against the box by the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label strip. Since the labels are closely connected to each other on the label strip, the label strip must be constantly stopped and stopped.
The label is affixed to the box with the labeling wheel moving at the same speed as the box. When the conveyor reaches a certain position, the label drive wheel accelerates to match the speed of the conveyor belt, and then decelerates to a stop.
Since the label may slip, it has a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor, and during the deceleration phase of the label, the drive wheel will reposition the position to correct any positional errors on the label strip.
