BINDING RINGS
The invention concerns a ring system for binding or joining that is characterized by a ring base and a back. The longitudinal base contains a plurality of rings divided lengthwise into separable complementary halves. The back of said base has a straight central guide in semi-circular segments and dovetails segmented longitudinally in the central axis thereof. Both halves can be separated or joined in the profile section by a hinge membrane. The back is a straight, independent and separable profile serving as a joining clamp by means of an inner profile in the form of a V-shaped groove that slides along the dovetail profile. The outer profile of the back is variable and may be curved, straight or provided with an engraved design.
