The Pyongyang special fittings branch factory under the Pyongyang Kim Jong Suk Textile Mill has newly set up more than ten processes for producing special fittings for looms including the processes for producing spools and wooden bobbins.

“Our factory has established one production process after another by relying on its own technical force in order to develop and produce new special fittings,” said senior engineer Hwang Ju Nam.

For its high utility value, the newly developed replaceable flat heddle is very popular.

According to Hwang, as a loom comprises thousands of flat heddles, when one of them went wrong in the middle part while the loom was in operation, the machine had to be dismantled and it took considerable time and effort to reassemble it after repair.

The technicians of the factory, in collaboration with scientific research units, hit upon a rational structure of a replaceable flat heddle which they can replace with other one without dismantling the loom and set up its production process, thus remarkably reducing the expenses and time for the replacement.

The factory brought great benefits to the country by ensuring the domestic production of the gripper spring which was imported previously.

It also intensified research into the improvement of the hardness of the rapier band header of an elastic staff loom and established a production process relying on the carbon fibre material, thus increasing the lifespan of the header over two times.

In addition, it devised and introduced various jigs and other devices needed for cutting, bending, die forging and heat treatment of materials and newly established some production processes to normalize production.
