ABSTRACT OF THE DISCLOSURE The method of making a tubular wire basket from a continuous wire strand comprises laying the strand in a series of back and forth bights aligned in the form of a tubular cage open at both ends, helically coiling the wire across the bights to form a contin- uous helical wrap, and welding the wire at the cross- ing points. An apparatus for making the tubular wire basket comprises a collapsible mandrel having a central shaft, a hub member mounted on one end thereof, and a plurality of radial arms pivotally connected at one end to hub member and circumferentially spaced around the shaft, the arms being adapted to be swung toward and away from the shaft, and to be held at regulatable angles relative to the shaft. The mandrel is provided with guides for holding the wire strand while it is being wound upon the mandrel, the guides being disposed circumferentially about the shaft.
