Problems solved by technology
The main defect of catheter binding is that due to the resilience of the metal after deformation, there is a phenomenon that a single page of the text will fall off over time, resulting in the phenomenon of falling off page by page, especially when binding only a few sheets of copy paper.

Embodiment Construction
[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to Claims that define what is said.
[0022] see example Figure 1 to Figure 6 As shown, a grooved envelope for office binding is composed of a metal U-shaped groove 1, a back cover cover film 4, a U-shaped adhesive film connector 9 (consisting of a single-sided adhesive film 2), and an anti-rebound pad 3; The adhesive film connecting body 9 connects the back cover cover film and the anti-rebound pad 3 and puts it into the metal U-shaped groove 1, forming a ridge groove 7 at the bottom of the U-shaped adhesive film connecting body 9; at the position of the anti-rebound pad 3 On the inner side of the metal U-shape...

The invention discloses a groove-shaped envelope for office binding and a manufacturing method thereof. The groove-shaped envelope for office binding is composed of a metal U-shaped groove, a back cover cover film, a U-shaped adhesive film connector, and an anti-rebound pad. The U-shaped adhesive film connector connects the back cover cover film and the anti-rebound pad and puts it into the metal U-shaped groove. A ridge seal groove is formed at the bottom of the U-shaped adhesive film connector. The anti-rebound pad is an elastic tape set in the ridge seal groove. side. The invention adopts the composite manufacturing technology, so that the envelope is manufactured efficiently, neatly, firmly and with good consistency. During use, the metal U-shaped groove is squeezed to clamp the U-shaped adhesive film connector, the anti-rebound pad and the information booklet in the envelope. Due to the deformation and the anti-rebound pad cannot rebound after being compressed, the deformation pressure is locked. The information booklet is not easy to fall off. The connection between the back cover cover film and the U-shaped film is easy to read, and the groove on the back of the metal U-shaped groove seal has a decorative surface that can be written on. The invention has the advantages of simple and convenient use and good practical effect.
Description
technical field [0001] The invention relates to the technical field of bookbinding envelopes, in particular to an office bookbinding envelope and a method for making the envelope. Background technique [0002] At present, the first requirement of office binding is: reliable binding, that is, there should be no page drop or easy to drop pages during the text flipping process, which means poor reliability; the second is work efficiency, tedious binding operation or step-by-step operation Specifications will greatly reduce work efficiency; then there are requirements for beauty, easy flipping, and pages that can be added or subtracted. [0003] There are two main methods commonly used in office binding at present, namely punching binding and hot-melt adhesive binding. Punch binding, as the name suggests, is to punch the text pages first, and then use different forms of binding consumables to complete the binding of the text. Punch binding generally does not require prefabricat...
