摘要： PURPOSE:To detect the tension of a stranded wire continuously with simple construction by providing a pulley which is made freely slidable in the tension direction of the stranded wire on the inlet side of a take-off capstan of a wire twister, and connecting a load cell to said pulley. CONSTITUTION:This device consists of a capstan shaft 10 into which a hollow shaft 6 is fitted and a clearance 11 is formed between the shaft 10 and the shaft 6. Since there is said clearance 11, a pulley 5 can slide freely in the tension F direction of a stranded wire 1 when the tension of the wire is exerted upon the pulley 5. If the tension F of the stranded wire is exerted upon such pulley 5, the force trying to slide the pulley 5 is generated and this force is conducted via a connecting bar 7 to a load cell 3. Then the tension F is read directly from the cell 3 whereby the tension is known easily.

摘要： PURPOSE:To improve the workability in production and mechanical strength of a product by providing a pair of right and left rugged engaging parts along both side edges of an opening for mounting an optical fiber provided in the longitudinal direction of a pipe and mounting the optical fiber in the pipe through the opening then fitting and detaining the recess and projecting part along both side edges in the opening of the pipe. CONSTITUTION:A pair of right and left rugged engaging parts 7 and 8 are provided in the opening 6 of a pipe 1 along both side edges thereof and after an optical fiber 2 is mounted into the pipe 1 through said opening 6, the pipe 1 is passed through a die to close the opening 6 and the recess 7 and projecting part 8 along both side edges of the opening of the pipe 1 are fitted and detained, by which the need for welding the seam of the pipe 1 is eliminated. The working efficiency in producing this kind of a product is improved and moreover the need for exercising care for preventing the damage of the fiber 2 housed in the pipe 1 in the stage of welding the seam thereof is eliminated.
