Abstract
A labeling system employs a multi-processing computer control system for a servo motor which drives a label-carrying web. The system is responsive to the physical position of the labels and the physical position of containers or similar objects to which the labels are applied. The label application motion controller identifies the machine position and performs the mathematical calculations needed to create a piecewise continuous function motion profile required to achieve label contact at a predefined contact point on the surface of each container. Multiple functions may be used to construct a motion profile, which smoothly accelerates the label at a calculated acceleration needed to cause a label to arrive at the defined contact position on a container and to decelerates the carrier web after application. Correction for measured label registration error is provided for. Because the position of the label is based on the position of the container and a motion profile is calculated for each application, a fixed initial staging position of the label prior to application is not needed.
