See how bottom labels are applied to packages
As the product moves along the conveyor, photoeyes will determine the leading edge. Once the product interrupts the photoeyes, a countdown will begin. After a predetermined time a label will be applied as the product moves over the bottom label applicator. The rate of label advancement matches the conveyor speed thereby ensuring proper label placement.
The sequence above is the same whether a top or bottom label is applied.
For applications needing a label on both the top and bottom of the package, Vande Berg Scales will build a combination top/bottom label applicator that exactly matches your needs.
