Problems solved by technology

[0003] There is currently known a hot-melt binding technology, in which a U-shaped hot-melt adhesive is arranged at the bottom of the U-shaped groove, and a cover and a back cover are arranged on the protruding tops of the two sides of the U-shaped hot-melt adhesive on the inner wall of the U-shaped groove , whose thickness is equal to or greater than that of the side of the U-shaped hot-melt adhesive, so that the side page paper will not be blocked on the protruding tops of the two sides of the U-shaped hot-melt adhesive, but the front and back covers of thick materials are fixed On the inside of the hard U-shaped groove, it is very difficult to turn pages

Embodiment 1

[0029] As shown in Figure 1, a hot-melt binding clip includes a U-shaped groove 1, a U-shaped hot-melt adhesive 2 is provided at the bottom of the U-shaped groove 1, and the two ends of the inner wall of the U-shaped groove 1 are located at U-shaped A thickened layer 3 is arranged on the upper side of the hot melt adhesive 2 , and an active layer 4 is arranged inside the thickened layer 3 . The thickened layer 3 and the active layer 4 are in contact with the sides of the U-shaped hot melt adhesive 2 . The sum of the thicknesses of the thickened layer and the active layer is equal to the thickness of the sides of the U-shaped hot melt adhesive, and the end of the active layer outside the U-shaped groove is connected as a cover or back cover material.

Embodiment 2

[0031] As shown in Figure 2, a hot-melt binding clip includes a U-shaped groove 1, a U-shaped hot-melt adhesive 2 is provided at the bottom of the U-shaped groove 1, and the two ends of the inner wall of the U-shaped groove 1 are located at U-shaped A thickened layer 3 is arranged on the upper side of the hot melt adhesive 2 , and an active layer 4 is arranged inside the thickened layer 3 . The thickened layer 3 is in contact with the upper side of the U-shaped hot melt adhesive 2, and the end 6 of the active layer located in the U-shaped groove is not in contact with the upper side of the U-shaped hot melt adhesive and forms a gap 5 , the end 6 tilts toward the U-shaped groove. The outside of the U-shaped groove 1 is also provided with a thickened layer 3, the thickened layer 3 on the outside of the U-shaped groove 1 is connected with the thickened layer 3 on the inside of the U-shaped groove 1, and the thickened layer 3 can be As a cover for hot-melt binders. The material ...

Embodiment 3

[0033] As shown in Figure 3, a hot-melt binding clip includes a U-shaped groove 1, a U-shaped hot-melt adhesive 2 is provided at the bottom of the U-shaped groove 1, and the two ends of the inner wall of the U-shaped groove 1 are located at U-shaped A thickened layer 3 is arranged on the upper side of the hot melt adhesive 2 , and an active layer 4 is arranged inside the thickened layer 3 . The thickened layer 3 and the active layer 4 are in contact with the upper side of the U-shaped hot melt adhesive 2 . The outer side of the U-shaped groove 1 is also provided with a thickened layer 3, and the thickened layer 3 can be used as the outer skin of the hot-melt binder. The sum of the thicknesses of the thickened layer and the active layer is equal to the thickness of the side of the U-shaped hot melt adhesive, and the end of the active layer outside the U-shaped groove is connected as a cover or back cover material.

Abstract

The invention relates to a stationers goods, concretely relates to hot-melt bookbinding clamp for bookbinding the document. The said hot-melt bookbinding clamp comprises a U type groove. A U type hot-melt adhesive is in the bottom of the U type groove. A thickening layer is set on the upside of the side of the U type hot-melt adhesive at the two ends of the U type groove. An active layer is set inside the thickening layer. The structure of the said hot-melt bookbinding clamp is reasonable. The invention can make the paper smoothly slip into the U type groove, and being regularly and hard bound to ensure the cover and back cover freely flip over.

Description

technical field [0001] The invention relates to a stationery product, in particular to a heat-melt binding clip used for binding documents. Background technique [0002] Hot-melt binding is a technology that heats and melts preset hot-melt adhesives to glue loose-leaf paper into a booklet. The advantage of this bookbinding technology is convenient, fast. [0003] There is currently known a hot-melt binding technology, in which a U-shaped hot-melt adhesive is arranged at the bottom of the U-shaped groove, and a cover and a back cover are arranged on the protruding tops of the two sides of the U-shaped hot-melt adhesive on the inner wall of the U-shaped groove , whose thickness is equal to or greater than that of the side of the U-shaped hot-melt adhesive, so that the side page paper will not be blocked on the protruding tops of the two sides of the U-shaped hot-melt adhesive, but the front and back covers of thick materials are fixed On the inside of the hard U-shaped groov...
