Abstract:
A process for controllably registering a plurality of components of a continuously moving first layer with a plurality of components on a continuously moving second layer, comprising the steps of:providing a continuously moving first layer including a plurality of components,providing a continuously moving second layer including a plurality of components,representing the components of one of the continuously moving layers with a respective plurality of reference marks,sensing each of the reference marks and generating a reference mark signal in response thereto,measuring the distance between two successive reference mark signals and generating a repeat corrective control signal in accordance with preprogrammed instructions,selectively applying pressure to the continuously moving one layer in response to a generated repeat corrective control signal to adjust the distance between two successive reference marks,superimposing the continuously moving first layer and the continuously moving second layer together,sensing a reference mark and its corresponding component of the other layer, and generating a placement corrective control signal in accordance with preprogrammed instructions, andadjusting the speed of the continuously moving one layer in response to a generated placement corrective control signal to controllably register a reference mark on the continuously moving one layer with its corresponding component on the continuously moving other layer.
