Problems solved by technology

[0002] At present, the production of L-shaped film sheets is directly punched by the roll-cutting die knife of the L-shaped frame, and the L-shaped sheets are arranged vertically on the base film (such as figure 1 As shown), there are more waste materials between two adjacent sheets, which wastes raw materials. For a particularly narrow L-shaped film, it is punched according to the existing L-shaped frame rolling die knife, which will easily cause the L-shaped mold to warp. High defect rate

Abstract

The invention discloses a narrow L-shaped film and a production method thereof. The narrow L-shaped film comprises a bottom film body, and a plurality of L-shaped film bodies are arranged on the bottom film body in an inclined shape at intervals. The manufacturing method comprises the steps that the bottom film body is adhered with a product film body; rolling cut is carried out from one surface of the product film body to the bottom film body through a first rolling-cut film body; materials in a mould frame rolling cut by the first rolling-cut film body is removed; a second rolling-cut film body is adopted to roll and cut from one surface of the product film body to the bottom film body position; and the material outside the mould frame rolling cut by the second rolling-cut film body is removed to form a finished product. According to the narrow L-shaped film and the production method thereof, the L-shaped film is formed by adopting two rolling-cutters to rolling and cutting twice, sothat the edge warping phenomenon generated during the narrow production of the L-shaped film is effectively prevented, and the yield of product production is improved; and the L-shaped film is arranged and produced in an inclined mode, so that excessive waste materials between product intervals are avoided, and raw materials are saved.

Description

technical field [0001] The invention relates to a cutting die for sheet material production, in particular to a narrow L-shaped film and a production method thereof. Background technique [0002] At present, the production of L-shaped film sheets is directly punched by the roll-cutting die knife of the L-shaped frame, and the L-shaped sheets are arranged vertically on the base film (such as figure 1 As shown), there are more waste materials between two adjacent sheets, which wastes raw materials. For a particularly narrow L-shaped film, it is punched according to the existing L-shaped frame rolling die knife, which will easily cause the L-shaped mold to warp. The defect rate is high. Contents of the invention [0003] The object of the present invention is to provide a narrow L-shaped membrane and a production method thereof in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted in the present...
