  • Patent number: 6955493
    Abstract: A system for binding books includes a flexible binding material in the form of a stud having top and bottom caps. The stud is inserted into signature staples that protrude from the body of the signature to form stud holes. The binding material can be any material that is extremely flexible, including silicone, metals, etc., as long as it allows the signatures to open in a lay-flat manner either at the signature interfaces or in the body of any signature. The flexible binding material can also be used to temporarily bind pre-punched pages of a book by inserting the flexible binding material into the pre-punched holes to facilitate lay-flat opening of the book.

  • Patent number: 5224788
    Abstract: A Direct Access Modular Binder containing one or more posts. Each post is comprised of two or more interconnected independent locking modules. These locking modules can easily be inserted or removed to change the length of the post to efficiently accommodate varying amounts of paper. The modules additionally function to permit direct access for insertion/removal of pages or modules anywhere along the post. The modules in the post may contain a telescoping feature. The module(s) containing a telescoping feature are optimally positioned at the end(s) of the post and fixedly attached to the post holding strips. The strips, which hold the posts' ends, may be hingedly attached to the front and back covers. The telescoping feature permits the binder to be automatically compacted (when not in use), for efficient storage, and temporarily expanded (when in use), to provide space for the user to insert/remove paper or modules. The modules which make up the post are easily locked and unlocked.
