摘要：
The invention relates to a method for manufacturing a conveyor apparatus, a conveyor screw, in which method at least one object longitudinally hollow and open in both ends is formed in order to achieve a threaded surface on the inner surface of the object and/or on the outer surface of the object. According to the method round at least one object (1,21,42,56), longitudinally hollow and open at least in one end, it is installed at least one-piece mould (2,22,41,53), which is shaped as a holding surface of a desired threaded surface and that it is led into the object (1,21,42,56) rounded by the mould (2,22,41,53) material, wherein it is created pressure, and by means of the pressure it is achieved a threaded surface (12, 13,32,44,57), which can be utilized in transportation of material from one position to each other.
