ストが高く付くという不都合がある。Further, in order to simplify the assembly of the spinning machine stand in the spinning factory, the machine body is composed of units of a predetermined length, and the units assembled in the spinning factory are transported to the spinning factory, and the spinning is performed. At the factory, the spinning machine stand is assembled by connecting the units. The duct is formed to have a length of about 2 m for convenient transportation. In this case, seven or eight ducts are required to form a duct on one side of the machine frame even with a spinning machine machine having 200 spindles on one side. However, since the duct is bulky, there is a disadvantage that the transportation cost is high.

る。When a cylindrical duct is divided into a plurality of component pieces, a large number of ducts are kept in a tubular shape by disassembling each component piece during packing for transportation. Compared with packing, the volume at the time of packing is much smaller, so that packing and transportation costs are reduced. However, conventionally, since each component is connected by the gob set 37, it is necessary to hit the gob 37b or to perform crimping after connecting the bent portion 37a and the gob 37b of the two components 31a, 31b. Therefore, there is a problem that the number of assembling steps is increased.
