ABSTRACT:
An improved cover breaker assembly may be used to sequentially apply covers to books of different thicknesses or to books of the same thickness. The cover breaker assembly includes inner and outer breaker members which are engageable with a cover on each of the books in turn. The inner breaker member is moved through the same distance from a retracted position to the same extended position during the application of a cover to either a thin book or a thick book. The outer breaker member is moved from a retracted position to an extended position through a distance which varies as a function of the thickness of the book. The inner and outer breaker members are effective to apply substantially the same force to either a thick book or a thin book. During the application of a cover to either a thick book or a thin book, the inner breaker member moves through the same distance along the path of travel of the book. During the application of a cover to a book, the outer breaker member moves along the path of travel of the book through a distance which varies as a function of the thickness of the book.
