Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

Example 1

A die-cutting coil product for reducing poor peeling phenomenon is shown in figures 1 and 2 and comprises a die-cutting product (2), a double-sided adhesive tape (3) and a conveying material belt (1) which are sequentially attached from top to bottom; the die-cut product 2 is rectangular, the length of the die-cut product is 4mm, the width of the die-cut product is 2mm, the die-cut product 2 is a PET film die-cut product, and the thickness of the die-cut product is 0.03 mm; the conveying material belt is a release film commonly used in the field of die cutting. A plurality of die-cut products (2) which are arranged in a matrix are adhered to the conveying material belt (1), as shown in fig. 2, the die-cut products (2) are arranged on the conveying material belt (1) in parallel, and the length direction of the die-cut products (2) is parallel to the advancing direction of the conveying material belt (2), so that the length of the die-cut products (2) along the advancing direction of the material belt is greater than that of the die-cut products (2) along the width direction of the material belt; the thickness of the conveying material belt (1) is 0.04 mm.

As shown in fig. 3, when peeling, the transport material belt 1 is taken up by the belt take-up roll and is output from the peeling gap of the peeling platform 4 so as to realize peeling with the die-cut product 2, and a bending angle 5 is formed between the transport material belt which is not peeled off and the transport material belt which is peeled off.
