Abstract
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.

In a book having a flexible spine joining front and back covers and pages having elongated apertures proximate edges thereof for binding within the book, flexible binding apparatus comprising:
- an integral flexible binding member having an elongated base strip and a plurality of flexible page holding fingers integral with the base strip and extending perpendicularly therefrom;
- means in said base strip proximate respective fingers for connecting said base strip to one cover of said book;
- means proximate loose ends of said fingers opposite said base strip for connecting said fingers to another cover of said book across said spine;
- said fingers extending through said page apertures binding said pages between said covers;
- said binding member being made of flexible plastic material and each of said fingers of said binding member from adjacent said base strip and toward said loose ends of the fingers defining a flexible page holding portion of constant dimension, said base strip and said loose ends being connected to said respective covers, outwardly of said page holding portion;
- and
- said page holding portions bending with said spine when said book is closed and bending away from said spine when said book is opened.
