Abstract: A continuous form assembly of ultrasonically weldable sleeve blanks formed by an elongated flexible web has a longitudinal series of pairs of transversely spaced apart and generally longitudinally extending slits therethrough, each pair of slits partially defining an associated sleeve blank. Pin feed aperture formed in the longitudinally extending marginal portions of the web cooperate with a tractor feed mechanism of a sleeve forming apparatus to intermittently advance the web through the apparatus. An electrical conductor or groups of conductors manually fed into the apparatus engage the web and form an associated blank into a loop surrounding the conductor or group of conductors. Ultrasonic sealing and severing jaws simultaneously join opposite end portions of the sleeve blank together in assembly to form a tubular sleeve surrounding an associated portion of the individual conductor or a group of conductors and simultaneously sever the formed sleeve from the web.
