Abstract
The present invention provides a combination roller, a machine and process for cutting workpieces from a web moving at a first speed and depositing them on and bonding them to a substrate web moving at a second speed with the functions of cutting, transferring, and bonding all carried out on a single roller. The reduction in roller mass achieved by this roller and machine design permits driving the combination roller at variable speeds by means of a servomotor and servomotor controller. The resulting machine permits electronic rather than machine grade changes as the machine and process are used to produce products having different configurations.
