연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The invention relates to ultrasonic gap welding of flat woven fabrics. Specifically, the invention relates to a method of ultrasonic welding the seam termination yarn ends of a fabric using a controlled gap. A mechanical stop may be employed to control the distance or gap between the horn and anvil to a predetermined level based on the depth of welding and amount of weld energy. By adding another degree of control, the ultrasonic gap welding technique of the present invention is able to achieve fabric seams that are stronger than conventional seams, and ...

1. A seam in an industrial fabric formed according to a method comprising the steps of: (a) seaming the industrial fabric into an endless form by weaving terminal yarn ends of one or more warp yarns and/or weft yarns into the industrial fabric to form a seam area;(b) placing the seam area of step (a) between a horn and an anvil;(e) adjusting the horn and/or the anvil to create a predetermined gap between the horn and the anvil; and(d) welding the terminal yarn ends of step (a) to an adjacent yarn and/or to a yarn that the terminal yarn ends cross over, b...
