The glass bottles neatly on the feeding conveyor belt of the labeling machine, and convey the glass bottles to the labeling station through the conveyor belt. The self-adhesive label is usually wound on the label reel. The labeling machine pulls the label from the reel through a traction device, and passes through a series of guiding and tensioning devices to keep the label in a flat and stable conveying state. When the glass bottle arrives at the labeling station, the labeling head of the labeling machine will peel the label from the base paper and accurately stick it on the surface of the glass bottle.
After the label is attached to the glass bottle, the labeling machine is usually equipped with a smoothing device, such as a roller or a scraper, to smooth the label, eliminate the bubbles between the label and the glass bottle, and make the label stick to the glass bottle more evenly.
