Description

Shoes toe a portion molding unit

The present invention relates to a toe partial forming apparatus of a shoe.

Conventional shoes have maintained the shape by inserting a soft plastic or a solid pool (HOT HELT) in the back portion to heat and rapid cooling, but to maintain the shape as a soft plastic or solid pool in the front part (Toe) Was technically difficult to heat and rapidly cool.

The reason is that the back part of the shoe has no big change in appearance and uncomfortable wearing after the shoe is completed even though the back part of the shoe is not molded correctly according to the size (standard) of the shoe. As the height and width of the toe are different from each other, it is very difficult to form an accurate shape accordingly. In order to solve this problem, in order to solve the problem that the toe portion is crushed by sewing stitching thick fabric or double inner skin as a substitute of soft plastic or solid paste, quality deterioration and material loss and labor cost This was a factor in the cost increase due to overload.

The present invention was devised to solve the above problems, and the subject matter of the present invention is a soft plastic (soft PVC) or a solid paste (HOT MELT) inserted into the core body between the upper fabric and the inner skin of the front toe of the shoes. After heating, activate it sloppyly, place it in a cage plate, fix it with a clamp, and then lower the toe band so that the toe portion of the upper clamped to the cage plate is removed by the toe band. It is press-molded according to the shape so that the shape is maintained without changing the shape of the toe part even after the last dislocation.
