Description

TECHNICAL FIELD [0001] The present invention relates to an eco-friendly interior material manufacturing apparatus for a leather sheet capable of manufacturing an environmentally friendly interior material for a leather sheet, and a jig member applied to the environmentally- for leather seat, and jig member at the manufacturing apparatus of the environment-friendly interior material}

The present invention relates to an eco-friendly interior material manufacturing apparatus for a leather seat capable of manufacturing an eco-friendly interior material for a leather seat, and a jig member applied to the eco-friendly interior material manufacturing apparatus for the leather sheet.

The leather sheet is made of leather and is mounted on a vehicle, an aircraft, or the like, and can be seated by an occupant. The interior material for the leather sheet constitutes the surface of such a leather sheet, and refers to a base material and a leather bonded to each other.

Here, foams and the like are widely used as the substrate, and artificial leather as well as natural leather are widely used as the leather.

As a method of manufacturing a conventional leather sheet, a hot melt web, which is an adhesive film that melts and exerts an adhesive force when heat is applied, is put between a leather and a foam, and is pressed and adhered by a hot press, Method and so on.

However, according to the conventional leather sheet manufacturing apparatus, since the foam is melted by applying the flame, loss of the foam, that is, loss of the fabric is generated, and the surface of the foam becomes uneven in the process of melting and the surface of the interior material itself becomes uneven And it is difficult to apply various substrates because the foam must be melted. Since the foam surface is melted and bonded to the leather, the high temperature heat of the substrate surface There is a disadvantage that the leather may be damaged by the skin.

Further, according to the conventional method using a hot-melt web, there is a disadvantage that the hot-melt web unintentionally melts again in a high-temperature condition, and the foam and the leather are separated again.

Meanwhile, after forming the joints in which the leather and the foam are joined in the above-described manner, a pair of the joints must be placed facing each other, and then the edges of the joints must be sewn and bonded. Conventionally, The joining process is performed by cutting and joining, or by attaching leather to a wide foam, joining and then cutting the foam in a leather form, so that the edges of the leather and the foam coincide with each other.

However, according to this conventional method, when a pair of joints of a leather and a foam are put face to face with each other and the edge is sewn, the sewed edges of the pair of joints are formed thick due to the thickness of the foam, There is a disadvantage that it can not be seen clearly.

In order to solve this problem, a process of skiving, that is, a process of cutting a certain amount of foam at the edge, so that the edges of the leather can be sewn without the foam, is performed. According to such skiving, And the waste of manpower and energy for such skiving is severely worsened.
