Method of Manufacturing Flexible Visor of Hat and Visor of Hat of the Same}

The present invention relates to a method for manufacturing a flexible hat visor and a hat visor according to the present invention, and more particularly, to restore the original hat visor shape and to produce lightweight hat visors of various designs even when the stone is curled or wrinkled, and minimizes the overall weight of the hat. The present invention relates to a flexible hat visor manufacturing method and a hat visor by which a hat can be worn for a long time, can be easily rolled up and stored in a bag, and can be sold in individual packages in a cylindrical packaging box.

As is known, hats generally consist of a cap and a hat visor. In particular, the brim is manufactured by injection molding of synthetic resin to maintain a round shape.

Accordingly, in the related art, an injection mold for manufacturing hat visors had to be manufactured for each hat, and thus a large development cost was required, thereby increasing the cost of hat manufacturing.

In addition, the conventional hat visor is made of a hard synthetic resin to maintain the shape of the hat visor, when carrying or storing the hat visor was able to carry or store the cap portion folded or rolled, but because the hat visor portion does not dry easily, there was a problem that is difficult to carry and store .

Accordingly, in the prior art, the hat visor part was divided into two or three portions in the longitudinal direction so that it could be folded, but the hat visor connection was exposed to the outside, so the design of the hat visor had a crude problem, and the round shape could not be maintained in the process of wearing. The problem of deformation in the form of a bent structure was inherent.

Accordingly, in the related art, there is a limitation in manufacturing a cap with a soft brim because there is no device or a manufacturing method for manufacturing the cap brim with a soft material while maintaining a constant shape. There is an urgent need for development of a manufacturing apparatus and a manufacturing method.
