in an annular space between the pipe 1 and the core body 1a then wire drawing is performed by the same techniques as are shown in fig1 that is by roller die 3 fig2 c by a series of die plates 4 fig2 d by swagging rollers 5 fig2 e and by an extruder 6 fig2 f the pipe 1 is reduced in diameter by abovementioned wire drawing operation as is shown in fig2 g wherein the core body 1a has a reduced diameter 1 39 while the pipe 1 has a reduced diameter l 39 under this condition the composite of the core 1a powder material 2 and the outer pipe 1 is subjected to preliminary sintering during which the core body 1a may be burnt if the core 1a is made of combustible material as is the fig1 in this embodiment also it is possible to remove the counter layer 1 off the inner body 2 which is then sintered to produce a hollow sintered article as is shown in fig2 h it is apparent from the description abovementioned that the method for producing an elongated article of sintered powder according to the present invention is completely different from conventional process in which binder of organic compounds is used still more in the present invention a long.
