Abstract
A high speed system is provided for bringing a plurality of articles, each moving independently in a separate path and at its own speed into registration with each other at a processing station. In applying the invention to a case making machine, successive boards are brought into registration with successive sheet areas defined on a continuous web which moves at a predetermined constant speed. Each board moves at a speed greater than the web speed until registration with the desired sheet area is obtained. A counter measures the registration differential between predetermined detection indicia on each article by keeping track of the distance travelled by each indicium beyond a reference position in the path of the corresponding article. When registration is obtained, the articles are transported at a common speed to the processing station where the separate paths converge.
