Label Dispenser - Label Applicators

Label Applicators

Label applicators are fully automated and can range from simple slower speed models to large machines capable of applying hundreds or even thousands of labels per minute.

Applicators advance the label stock over the peeler plate until a portion of the label, called the "flag," is extended into the path of the oncoming package. When the package engages the label flag, the label web is advanced to match the speed of the package and label is either tamped or wiped on to assure adhesion. Proper alignment of the label on the package depends on sensors that sense the location/orientation of the package and label sensors that detect the location of the label edge. Package sensors can be a variety of Position sensors, often optical sensors or Ultrasonic sensors. Label sensors are usually Photoelectric sensors because they are inexpensive. But clear labels cannot be detected by photoelectric sensors. Capacitive and ultrasonic technologies are used for clear label detection.
