Single/Double Covering with spandex core yarn and polyester or nylon filament covering yarn can be performed on HKV141E. Typical configurations include spandex core yarns in the 20D–140D range with polyester or nylon covering yarns in the 75D–300D range. The yarn covering machine is able to produce stable spandex covered yarn for elastic textile applications.

The yarn covering machine adopts a single-layer welded frame structure with a lower operating position, making it easier to operate and maintain. It features a compact and stable structure that allows quick installation while keeping energy consumption low during operation. Spandex covered yarn is widely used in textile products such as garments, woven tapes, sports socks, and elastic fabric materials.
