Label application method

摘要

A unit for applying labels at predefined designated locations along the length of a moving web of material. The unit includes one or more label discharge mechanisms which remove labels from a carrier backing for discharge to a defined placement zone. The label discharge mechanisms are actuatable in response to commands from a controller to effect placement of the labels at designated locations along the length of the web. The controller initiates actuation of the label discharge mechanisms according to a variable timing sequence which is a function of the rate of travel of the moving web to which the label is applied such that label application takes place as the designated location to be labeled passes through the placement zone. The unit is adjustable to apply labels to webs traveling at different angles.
