Code 3515 applies to employers engaged in manufacturing textile machinery such as knitting machines, braiding machines, spinning frames, fly frames, roving frames, winders, pickers, carding machines, cloth laying machinery, dryers, steam pressing machines, washing machines and other similar machinery.  The operations contemplated by this classification are similar to a machine shop where lathes, milling machines, grinders, drill presses, and shapers are used to fabricate parts.  The fabricated parts are then assembled into completed machines. 

Manufacturing loom harnesses is included under this classification.  The process involves taking cotton yarn, which is then twisted on cord twisters and made into heavy cord.  The cord is then knitted into the harness on harness knitting machines.  Finally, the harness is placed on wood frames, shellacked by machine, dried and packed.

The machines are inspected for quality and operating performance prior to being packed and shipped to customers.
