Apparatus for forming corrugations of {37 zero{38 {0 pitch in coaxial cable

摘要

An apparatus for forming corrugations of "zero" pitch in coaxial cable includes a takeup drum which pulls the coaxial cable through a three jaw chuck or head at a speed related to the rotation of the head. The head includes three forming dies and three synchronizing gears which cooperate with the forming dies to synchronize movement of the forming dies for movement about the cable. By causing the takeup drum to pull the cable through the head at a predetermined rate, the forming dies cut parallel corrugations or "zero" pitch grooves in the cable jacket.
