Zusammenfassung: | The present invention relates to a mask manufacturing apparatus. The purpose of the present invention is to provide a mask manufacturing apparatus that performs marking on a fabric in the case of the first ultrasonic welding, when the marked part reaches a first cutting part and an error in the feeding distance occurs due to the change in the stretching length of the fabric, controls the stretching length of the fabric between the first ultrasonic welding part and the first cutting part, and controls the stretching length of the fabric according to the error of the feeding distance according to the stretching length by the marked part even in a second ultrasonic welding part and a second cutting part. Therefore, the outer part maintains a certain distance from the ultrasonic welding parts.
본 발명은 마스크 제조장치에 관한 것으로, 1차 초음파 융착시 원단지에 마킹을 행하고, 그 마킹된 부위가 1차 컷팅부위에 도달할 때 원단지의 연신길이가 달라짐에 따른 피딩거리의 오차가 발생한 경우 1차 초음파 융착부위와 1차 컷팅부위 사이에서 원단지의 연신길이를 조절하고, 아울러 2차 초음파 융착부위와 2차 컷팅부위에서도 마킹된 부위에 의해 연신길이에 따른 피딩거리의 오차에 따라 원단지의 연신길이를 조절함으로써 초음파 융착된 부위로부터 외곽부위가 일정한 간격을 유지하도록 한 마스크 제조장치를 제공하는데 그 목적이 있다. |
