Filed: 1993-05-10
Abstract: PURPOSE:To eliminate a deburring process and allow a collar to be easily fitted by forming a groove on the internal surface of a cylindrical body having C-shaped cross section and welding both sides of the groove. CONSTITUTION:A cylindrical body 9 made of resin for use as a collar 10 after fitted to a wire 3 has one side made open and is formed to have approximately C-shaped cross section. Also, a plurality of grooves 91 are formed on the internal surface of the cylindrical body 9, extending from one end thereof to the other. When the wire 3 is forced into the cylindrical body 9 via the open section thereof, the diameter of the body 9 increases in such a manner that a gap between both sides 9a and 9b is expanded. Thereafter, the diameter of the body 9 is made to shrink until both sides 91a and 91b of each groove 91 come in contact with each other by using ultrasonic vibrators 6A and 6B. Then, the body 9 is made to ultrasonically vibrate on the operation of the vibrators 6A and 6B, thereby welding both sides 91a and 91b. At this welding process, a part of molten resin projects as a bur. In this case, however, the bur projects inward in a radial direction from the internal surface of the collar 10, and not externally.
