본 발명은 자동차에 사용되는 카페트의 제조방법에 관한 것으로, 특히 금형에 설치된 열장치를 이용하여 플로어 카페트 원단과 흡음재를 동시에 성형 및 접합함으로써 제조원가를 절감함과 더불어 품질의 향상을 도모할 수 있도록 한 자동차용 플로어 카페트의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing carpets used in automobiles. In particular, the floor carpet fabric and the sound absorbing material are simultaneously formed and bonded using a heating device installed in a mold, thereby reducing manufacturing costs and improving quality. It relates to a method for producing a floor carpet for automobiles.

일반적으로 카페트는 자동차의 내부와 트렁크 등의 내장재로 사용되어지는 것으로, 카페트 원단과 흡음재 및 부직포로 이루어져 있는 것이다.In general, the carpet is used as interior materials such as the interior of the car and the trunk, it is made of a carpet fabric, sound absorbing material and non-woven fabric.

즉, 종래 기술에 의한 자동차용 카페트의 제조방법을 설명하면, 카페트 원단과 흡음재 및 부직포로 이루어진 소재를 압출기를 통해 압출 성형하고, 압출 성형된 소재를 로울러를 통해 이송시키는 백 코팅공정과, 상기 로울러를 통해 이송된 소재를 가열기를 이용하여 가열시켜 카페트 원단의 표면과 부직포의 이면에 흡음재가 접착되도록 한 가열공정과, 상기 가열공정을 통해 접착된 소재를 금형으로 성형 압착시켜 카페트프리폼을 얻는 성형공정과, 상기 성형공정으로부터 얻어진 카페트프리폼을 부착시키는 접착공정과, 상기 접착공정에서 부착된 카페트프리폼에 폴리우리탄을 발포시키는 발포공정과, 상기 폴리우레탄이 발포된 카페트프리폼을 트리밍하여 완성된 카페트를 얻는 트리밍공정으로 이루어지는 것이다.In other words, the method for manufacturing a carpet for a vehicle according to the prior art, the extrusion coating the material consisting of the carpet fabric, sound absorbing material and non-woven fabric through an extruder, and the back coating process for transferring the extruded material through the roller, and the roller Heating process to heat the material transferred through the heater using a heater to bond the sound absorbing material to the surface of the carpet fabric and the back surface of the nonwoven fabric, and a molding process of forming and compressing the bonded material through a mold into a mold to obtain a carpet preform. And a bonding process for adhering the carpet preform obtained from the molding process, a foaming process for foaming the polyuritan on the carpet preform attached in the bonding process, and a carpet finished by trimming the carpet preform in which the polyurethane is foamed. It consists of the trimming process obtained.

그러나, 상기와 같은 종래 기술은 카페트 원단과 흡음재 및 부직포로 이루어진 소재를 압출기를 통해 압출 성형한 후, 압출 성형된 소재를 로울러를 통해 이송시켜 백 코팅시킨 다음, 백 코팅된 소재를 다시 가열공정을 거쳐 성형공정으로 이루어지기 때문에 작업공수가 많아 작업능률이 저하되었고, 카페트가 완성된 다음 카페트의 불량을 확인할 수 있기 때문에 카페트 불량시 공정라인을 전부 교체해야 하므로 시설투자 및 작업손실이 많으며, 이로 인하여 제품원가가 상승되는 결점이 있었다.However, in the prior art as described above, after extrusion molding a material consisting of a carpet fabric, a sound absorbing material and a nonwoven fabric through an extruder, the extruded material is transported through a roller to be back coated, and then the back coated material is heated again.
