Beschreibung
Zusammenfassung:	PURPOSE:To provide the production method of a granular body filled tube capable of improving yield and quality of product. CONSTITUTION:The production consists of a process to supply a granular body to a tubular body on the way of forming a metal strip to a tubular body, a process to join both edges of tubular body by high frequency welding and a process to reduce the welded tube filled with granular body. In the production method of granular filled tube in which this forming device is actuated at the prescribed initial forming rate As and then is accelerate to a fixed normal forming rate An, in the processes to transit from starting to normal forming and of normal forming, the ratio of a granular body supplying rate B to a forming rate A is controlled to a rate of the prescribed granular body filling rate.
