The relief mold is applied to various fields such as a flexible printed circuit board, a double-sided tape, a packing material, an insulator, a precision processing material, a liquid crystal display device, and a protective film by the above-

Embossed molds process a workpiece with a blade having a specific pattern, during which chips cut by the blade are generated and these chips remain on the workpiece or are attached to the blade.

Conventionally, a worker removes a chip cut by a blade, and this operation takes a considerable time. In the case of a small-sized chip, the worker is not conspicuous and can not be removed frequently. Respectively.

In addition, in the case where chips are left on the relief mold, a cutting defect occurs to the workpiece following the remaining chip, and the defective cutting results in a defect of the product.

(Hereinafter referred to as "prior art 1") of the registered patent application No. 10-1577299, which is filed by the present applicant and is registered in the above-mentioned patent application, 1577301 entitled " Embossing mold apparatus and method of manufacturing a product using the same " (hereinafter referred to as " Prior Art 2 ").

Prior Art 1 is a technique for forming a hole in an object to be processed in accordance with a so-called half-cut operation, that is, a half cut operation, which is applied to the production of products such as a flexible printed circuit board, a double-sided tape, a packing material, an insulator, a precision processing material, a sticker, Technique 2 is a technique for forming a hole in an object to be processed in accordance with so-called perfecting operation, that is, complete cutting.

However, all of the prior arts must additionally include a step of separately supplying a release film for chip removal and removing the chip from the object to be processed, in order to remove chips generated from the object as the holes are formed.

Particularly, although the prior arts have greatly reduced the chip residual rate compared to the existing embossed molds, they are still rarely separated from the object to be processed, which is one of the fatal factors causing the final product to be defective.
