[0037] In the preferred embodiment, the u-shape element main body 10 is formed by punching a steel plate into a u shape via a punching machine. The anti-drop adhesive tape 11 can be made of rubber, silicone, plastic cement or other material. The wrappage 12 is made of paper, cloth or plastic cement, and other material is all right.

[0038] Referring to FIG. 3-4 and FIG. 1, the present invention further provides a method for manufacturing the u-shaped binding element, comprising following steps of:

[0039] (1) punching a suitable steel plate into a u shape via a punching machine, referring to FIG. 3;

[0040] (2) wrapping one or two up ends of the u-shaped element main body 10 with anti-drop adhesive tape 11 to form a single-side molding body or a double-side molding body, referring to FIG. 4;

[0041] (3) covering an external surface of the single-side molding body or the double-side molding body with a wrappage 12 to form the u-shaped binding element.

[0042] A specific method for manufacturing a simple type binding sleeve comprising steps of: embedding an integral body of a back cover-front cover-spine cover which is pre-packed in a middle of a u-shaped binding element, wherein the back cover-front cover-spine cover is made of paper or photographic film; putting one end of a text sheet 14 requiring binding into the simple type binding sleeve; and tightly pressing the text page and the binding sleeve by a press-binding machine; wherein a final press result is as shown in FIG. 7.

[0043] Further, referring to FIG. 8-9, the present invention further provides an application of the u-shaped binding element comprising steps of: combining the u-shaped binding element with a second back cover-front cover-spine cover 13b to form a hardcover binding sleeve; wherein the second back cover-front cover-spine cover 13b has a certain hardness and adopts a u-shaped binding element with two up ends covered with anti-drop adhesive tape; wherein a specific method for manufacturing the hardcover binding sleeve comprising steps of: forming the u-shaped binding element into a plate to form a plate-shape structure; covering the plate-shape structure on a middle portion of the first-back cover-front cover-spine cover; connecting both ends of the plate-shape structure with both ends of the back cover-front cover-spine cover; and hydraulic molding the plate-shape structure and the back cover-front cover-spine cover to form a hardcover binding sleeve as shown in FIG. 9.

[0044] In the preferred embodiment, the second back cover-front cover-spine cover 13b comprises an external surface 131b, an internal surface 132b and two internal core 133b, wherein the internal core is made of paper plate, in such a manner that the hardcover binding sleeve has a certain hardness; a middle portion of the external surface and a middle portion of the internal surface are closely laminated to form a first wrapping chamber, wherein the plate-shape structure is wrapped in the first wrapping chamber, and a first portion of both ends of the external surface and a first portion of both ends of the internal surface are fixedly pressed to form a connecting portion; a second portion of both ends of the external surface and a second portion of both ends of the internal surface are closely laminated to form a second wrapping chamber, each internal core is wrapped in the second wrapping chamber which is corresponded; both ends of the first wrapping chamber is connected with a second wrapping chamber via the connecting portion which is corresponded; and finally putting one end of the text sheet into the hardcover binding sleeve, and tightly pressing the text sheet and the binding sleeve by a press-binding machine.

[0045] Compared with the conventional art, the u-shaped binding element, its manufacture method and application provided by the present invention adopts pressing steel material to form the u-shaped element main body, wherein one up end or two up ends of the u-shaped element main body is or are wrapped with anti-drop adhesive tape and a wrappage is wrapped on an external surface of the u-shaped element main body wrapped with the anti-drop adhesive tape. The anti-drop adhesive tape added is capable of effectively decrease the bounding effect while metal clamping, i.e., the spring back amount of the anti-drop adhesive tape is greater than the spring back amount after the deformation of the u-shaped element main body. The position of the anti-drop adhesive tape is provided between the wall of the u-shaped element main body and the text sheet, and the anti-drop adhesive tape which is not capable of rebounding has an effect of preventing loose pages, so as to achieve the object of reliable binding. Thus, the u-shaped binding element and each kinds of back cover-front cover-spine cover are combined to form the binding sleeve. Utilizing the binding sleeve and a binding machine is capable of quickly completing text sheet binding and effectively solving the first requirement of binding: convenient and reliable, so as to make the binding more reliable, fast and convenient.

[0046] One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

[0047] It will thus be seen that the objects of the present invention have been fully and effectively accomplished. Its embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
