2 is a perspective view showing a decoration cover for TV decoration.

As shown in FIG. 2, the TV decoration cover 100 is attached along the lower end of a large TV to be used for decoration, and has a thin strip shape as a whole.

The decoration cover 100 is made of a metal material such as aluminum, and is formed by bending 90° about the body 13 while covering the body 13 covering the front of the lower end of the large TV and the lower end of the large TV. It consists of a wing portion (15).

In addition, both ends in the longitudinal direction of the decoration cover 100 are made of corner portions 11 surrounding both corners of the lower end of the large TV, and the wing portions 15 belonging to the corner portions 11 at this time are round bodies It takes a round shape continuously connected from the wing part 15 on the side of the part 13.

Here, the width W1 of the body 13 is preferably about 4 to 6 mm, and the width W2 of the wing 15 of the corner 11 is about 1 to 2 mm (for example, The finished width width dimension is preferably 1 mm).

3 is a perspective view showing a method of manufacturing a decoration cover for a TV decoration according to an embodiment of the present invention.

As shown in Fig. 3, as a first step, a first trimming step of forming the corner portions 11 at both longitudinal ends of the strip-shaped plate 10 is performed.

For example, using a known primary trimming molding device (not shown), the middle of the widths of both longitudinal ends of the plate 10 are taken out in a square shape, and two corners on both sides parallel to each other at the ends of the plate 10 (11) is to be formed.

Particularly, when the corner part 11 is formed, the width of the corner part 11 is substantially larger than the width W2 of the part forming the wing part 15 of the corner part 11. The corner portion 11 including the lip 12 is molded to have a width W3 of.

As a second step, the plate 10 is bent in the width direction to form a pair of side-by-side temporary products 14 including a corner portion 11 and a body portion 13 on the plate 10. Perform the first bending step to ensure that.

For example, a plate 10 in which corner portions 11 are formed at both ends using a known primary bending molding apparatus (not shown), and a portion to be made of the corner portions 11 is formed Bending in the width direction is first bent into a shape having an approximately "C"-shaped cross section with both ends of the width extending outward.
