[0002] Online labeling machines are devices that can stick rolled paper or metal foil labels on specified packaging containers or products. The labels have adhesive on the back and are regularly arranged on the glossy backing paper. The peeling mechanism on the labeling machine can automatically peel them off. Labeling can complete various operations such as flat labeling, single-sided or multi-sided labeling of packaging, cylindrical labeling, partial or full coverage of cylindrical labeling, and labeling of concave and corner parts.

[0003] At present, the technology of single-side online labeling machines on the market is very mature. Basically, if you want to label on the left side online, you need to buy a labeling machine for the left side, and if you want to label on the right side online, you need to buy a labeling machine for the right side. Many units need to buy two online labeling machines for one line, one for the left and one for the right, to adapt to different labels, which makes the company's equipment investment larger and occupies more space.
