<p><P>PROBLEM TO BE SOLVED: To provide a force feeding conduit for an adhesive mixture that can be used repeatedly. <P>SOLUTION: The force feeding conduit for adhesive mixtures is in a double pipe structure of an inner pipe having 200-400% expansion rate, and an external tube that has an inner diameter being shorter than the maximum expansion radius (outer diameter) of the inner pipe and does not allow the diameter to radially increase. In this case, the expansion rate indicates the increase rate of the outer diameter of the inner pipe that increases by the radial expansion of the inner pipe, and an expansion rate of 200-400% indicates that the outer diameter of the inner pipe after expansion becomes two to four times larger than the inner pipe in a normal state before expansion by the radial expansion of the inner pipe in the radius direction. Additionally, the maximum expansion radius (outer diameter) of the inner pipe indicates the radius (outer diameter) of the inner pipe immediately before destruction of the inner pipe radially expanded when the inner pipe that is 100 m long is retained under atmospheric pressure, and one end is sealed for supplying fluid (for example, air) with an air supply pressure of 5.5 Kg/cm<SP>2</SP>for expansion. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
