Abstract: Spine strip stock material, being withdrawn from a supply reel, is cut into pieces of the desired length and the pieces are subsequently fed into positionally accurate contact with cover boards which are moving on a conveying system. High cutting and feeding accuracy are achieved by a servomotor control system which, in response to sensing the motion of the cover boards, stops the infeed of the stock material, clamps and cuts the stationary stock material, feeds the cut spine strip pieces to a waiting position and then moves the pieces from the waiting position into contact with the cover boards.

Abstract: An expandable capacity album or binder for storing and displaying artwork or photographs retains the appearance of a library bound hardcover book at any state of expansion. The front cover and back cover are hinged to a spine which has page retaining channels that allow looseleaf pages to be inserted into or removed from the album. Together, the spine and the channels are adjustable so that the album will expand and contract for different capacities. The outside of the album is covered with leather or cloth to give the album the appearance of a library bound hardcover book. In between the spine and the covering is a resilient material such as plastic foam which can compress or expand so that the covering will always look properly fitted to the spine even when the spine is expanded or contracted to change the capacity of the album. In this way the album maintains its library bound appearance at any state of expansion.

Abstract: In the .[.higher priced grade of books, which for example are known generally as the "hard copies" as distinguished from the more economically priced.]. so-called "paper backs", it is customary to protect the books .[.by.]. .Iadd.with .Iaddend.A so-called .[.dust shield or.]. protective cover. These protective covers are generally highly colored and carry a pictorial image of the author, or of some primary incident in the story. When it is necessary to put down the book without finishing reading it in one sitting, it is desirable to have a book marker so that one's place can be quickly and easily found so that the story can be continued without regression. Frequently a portion of a page of newspaper or magazine is torn off to provide a small book marker. By the present invention a narrow perforated .[.edge.]. .Iadd.strip .Iaddend.of the .[.fold under flap of the book.]. .Iadd.protective .Iaddend.cover may be torn off from the .[. dust shield or.]. .Iadd.protective .Iaddend.
