Abstract

An adhesive film which reliably completely covers the spine side of a book block, prior to mating with a cover, is applied by an applicator roller which is controlled to rotate at speeds which are a function of the book block linear velocity and the location of the book block relative to the roller. The applicator rotational speed is determined from stored information and, depending on book block location, will either be greater or less than book block velocity.
