METHOD AND APPARATUS FOR MANUFACTURING SMALL DIAMETER, THICK WALLED, CABLE SHEATHS |
摘要 |
There is disclosed a method and apparatus for manufacturing a small diameter, thick walled, cable sheath by controllably driving a metal strip in a longitudinal direction while it is trimmed and formed into a hollow tubular member; continuously welding the longitudinal abutting edges of the hollow tubular member in association with cooling the tubular member in the vicinity of the welding by surrounding at least 60% of its circumference with a coolant, while maintaining the resulting longitudinal welded seam free of the coolant; and continuously drawing the cooled hollow tubular member in the same direction as the metal strip is driven. |
