发明名称 Book binding
摘要 An improved book binding for heavy or bulky pages includes a binding member having a base strip and perpendicularly extending flexible fingers. The base strip and opposite finger ends are secured to the book near the flexible spine while the fingers provide flexible page holding portions which can flex with the spine to expand and contract in accommodating varying numbers of pages. Flexible binding flanges in several embodiments serve to connect the binding element to the book so the covers can be opened and closed independent of the flanges and the binding member.
