Abstract
A high speed labeling machine is provided which includes a constant tensioning device for maintaining tension downstream of the metering roll at a substantially constant predetermined level thereby improving both metering and dispensing of labels. The constant tensioning device may also function as a driver for pulling the continuous web of material through the labeling machine thereby reducing the driving load on the metering roll, thus both providing more effective and accurate metering at a given web speed while also allowing higher web speeds to be achieved.
