They are designed with varying sizes and features which are often specific to the type of label they can dispense and to the degree of automation desired.
They are operated by hand and are not automated, but still assist in the process of removing labels from their liners.
When the liner is forced around a tight radius the label lifts away and protrudes through the front or top of the dispenser.
They were originally designed for multiple-row address labels for bulk mailing houses.
On average a good mailing house employee could apply approximately 500 labels per hour to envelopes.
The first electric dispenser was designed with the limit switch on the left of a 16" wide machine.
The labels are also peeled without the natural curl that will happen when pulled from the backing paper with fingers.
