Description

Buckle binding coil

Technical Field

The invention relates to the field of binding, in particular to a buckle binding coil.

Background

In modern printing production, currently known signature joining methods can be divided into two types, a stitch joining method and a non-stitch joining method. The stitching connection is made by connecting the signatures with the fiber and the metal wire, and the method can be used for the integral stitching and the one-signature stitching of the signatures. Currently, the fiber sewing is mainly used for sewing and stitch-locking, and the iron wire sewing is mainly used for side-stitch and saddle-stitch.

However, books and periodicals manufactured by the binding method cannot be completely laid flat when pushed open for reading, and books with a little more pages are even arched after being opened, so that readers can mark or take notes on pages very difficultly, thereby not only affecting the quality of the notes, but also wasting time; and even the text on the page is inconvenient to view. The prior art discloses 2019211030282 patent No. 7/14/2020 entitled open and close snap-on binder coil, but the connecting strips in the binder coil need to be folded over each other so that the first and second ring members form a clip-like structure. The above prior art is preferably applied to binding of a text by using a coil alone, but since the connecting strips need to be folded with each other, the connecting strips have poor connectivity with the inner surface of the front cover of the text, and cannot be effectively matched with the text having a cover.
