Detailed implementation manners

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0046] Such as Figure 1 、 2As shown in the figure, in an embodiment of the present invention, a folding tape includes a first tape body 101, a second tape body 104, and an intermediate connecting body 107. A first adhesive layer 102 is provided on one surface of the first tape body 101, and a first release paper layer 103 covers the surface of the first adhesive layer 102; a second adhesive layer 105 is provided on one surface of the second tape body 104, and a second release paper layer 106 covers the surface of the second adhesive layer 105; one side of the intermediate connecting body 107 is connected to the first tape body 101, and the other side of the intermediate connecting body 107 is connected to the second tape body 104. A crease is provided on the intermediate connecting body 107 along the length direction; when the intermediate connecting body 107 is in the unfolded state ( Figure 2 in the figure is the state of being unfolded by 90 degrees), there is a spacing between the first tape body 101 and the second tape body 104, and the size of this spacing is determined according to the gap requirements of the working object. The first adhesive layer 102, the first release paper layer 103, the second adhesive layer 105, and the second release paper layer 106 are on the same side of the intermediate connecting body 107.

[0047] The beneficial effects of adopting the above technical solution are as follows: When operations such as gluing, spraying, and polishing are required at the corners of the working object, place the crease of the folding tape along the corner joint line. Protect one surface of the working object through the first tape body, protect the other surface of the working object through the second tape body, and then tear off the intermediate connecting body, so that a neat working gap is exposed. After the operation is completed, remove the first tape body and the second tape body, which can effectively prevent the pollution of the working object, is convenient for operation, and is more beautiful.

[0048] In the present invention, there are various ways to form the first release paper layer and the second release paper layer. It can be that two separate release papers are respectively covered on the first adhesive layer and the second adhesive layer, or a whole release paper covering the first adhesive layer and the second adhesive layer is die-cut or slit. There are also various connection forms between the intermediate connecting body and the first tape body and the second tape body, such as semi-cut connection, non-continuous cutting line connection form, and adhesive attachment form. When the two sides of the intermediate connecting body are connected to the first tape body and the second tape body respectively by the semi-cut line method, the connection strength of the semi-cut line should be such that it can be easily torn by hand, which is convenient for construction operations. For example, when manufacturing the folding tape by using the hob slitting process, take a wider tape roll with a release paper. When the tape extends, two semi-cut lines are rolled out on the tape surface side by two hob blades (i.e., the first tape body, the intermediate connecting body, and the second tape body are formed in sequence), and the whole release paper is cut into two parts on the release paper side by a hob (i.e., the adjacent first release paper layer and the second release paper layer), and finally, it is folded and wound along the first release paper layer and the second release paper layer.

[0049] Such as Figure 1 、 2As shown, in some other embodiments of the present invention, a third adhesive layer 108 is provided on one surface of the intermediate connector 107 (the "one surface" described here refers to the intermediate connector being in an unfolded and flattened state, and Figure 1 The intermediate connector 107 is in a folded state, so the "one surface" described here is Figure 1 The middle refers to the upper surface and the lower surface of the intermediate connector 107 when it is folded in half), one side of the intermediate connector 107 is adhered to the surface of the first belt body 101 opposite to the first adhesive layer through the third adhesive layer 108, and the other side of the intermediate connector 107 is adhered to the surface of the second belt body 104 opposite to the second adhesive layer through the third adhesive layer 108. The first release paper layer 103 and the second release paper layer 106 extend and cover the third adhesive layer 108 of the intermediate connector 107. The beneficial effect of adopting the above technical solution is that the intermediate connector is an independent belt body, which is easier to tear off and more convenient to operate.

[0050] In some other embodiments of the present invention, the spacing between the fold on the intermediate connector and the first belt body is the first spacing, and the spacing between the fold on the intermediate connector and the second belt body is the second spacing, and the first spacing and the second spacing are equal or unequal. The beneficial effect of adopting the above technical solution is that folding tapes with different spacing specifications can be manufactured according to the needs of the work object.

[0051] In some other embodiments of the present invention, the folding tape is folded along the fold of the intermediate connector, and the first release paper layer and the second release paper layer are on the outer surface (i.e. Figure 1 The folded tape is packaged in a strip or roll form. The above technical solution has the beneficial effects of facilitating packaging, facilitating the stable maintenance of the fold position, and being directly unfolded and used in subsequent operations.

[0052] Combine the following Figures 3a - 3j , describes the method of using folding tape to align corners, including the following steps:

[0053] Step 1: Place the folded edge of the folding tape 10 along the corner of the work object ( Figure 3a );

[0054] Step 2, remove the first release paper ( Figure 3b ), locate along the corner joint line, and apply the first belt body to the lower horizontal surface of the work object ( Figure 3c );

[0056] Step 4: Remove the intermediate connector (Figure 3f ),a caulking gap is exposed at the corner of the work object Figure 3g );

[0057] Step 5, use a caulking tool to apply caulking along the caulking gap Figure 3h ), and finally tear off the first tape body and the second tape body from the work object Figure 3i ), to obtain a beautiful, uniform and consistent glass glue sealing strip Figure 3j ).

[0058] The beneficial effects of adopting the above technical solution are: effectively preventing the pollution of the work object, convenient operation, and capable of forming a neat and uniform glass glue sealing strip.
