摘要

The impressed molecular structure of the binder blank (1) approximates to binder spine section as against the binder fingers and end shape which are obtained in separate passes. The fingers overlap the spine by a set distance and the finger material thins out from tip to spine. Spine section is optional and the spine is fitted with a connector for a wide range of paper etc sets etc. This connector comes in dovetail form or simply openings in the spine itself. The set of papers etc can take the form of a transparently cased document or book set..
