った。2. Description of the Related Art Conventionally, a contact rod used to detect a yarn breakage of a loom has a structure in which an outer plate bent in a U shape is insulated to sandwich the middle plate and the upper edge of the middle plate is exposed. As a method of manufacturing the contact rod, generally, a method of bending the outer plate into a U-shape, sandwiching the inner plate, and pressing the outer surface with a roller to closely process the outer plate and the inner plate is adopted. It was However, in the conventional method, uniform adhesion over the entire length cannot be obtained, and the adhesion is weak, and the edge of the outer plate opens due to latent elasticity over time, which causes dust (fly, staff). It has a drawback that it is likely to accumulate and it will not operate correctly.

By pressing, the outer plate is pressed into a U-shaped body with a squeeze diaphragm shape, and then the middle plate, which has been insulated from the openings in the squeeze diaphragm shape, excluding the upper edge, is pushed into the opening. Then, by integrating the two into a single unit, it is possible to provide a contact rod that has excellent adhesion and prevents the outer plate from spreading over time (Japanese Patent Publication No.
-8054).

し得る接点杆を製造する方法が求められている。In the above-mentioned manufacturing method, it is needless to say that the degree of adhesion is remarkably improved as compared with the conventional method in which roller rolling is used as the means for closely contacting the middle plate and the outer plate. A sufficient function can be exhibited without damaging the dropper's sliding movement, and this manufacturing method is a process for mass-producing the product, and can provide a contact rod having an excellent mass. However, with the recent increase in demand, there is a demand for a method of manufacturing a contact rod that can be mass-produced more than the above method, can provide an inexpensive contact rod, and can function to the maximum as a part of the yarn breakage detection device. Has been.
