The problem: heavy packages punish ordinary bolsters
Fishnet yarn twisting, rope and twine twisting runs coarse, heavy packages at moderate speeds — and the spindle bolster carries that package weight for the whole doff. A bolster built for fine-count ring spinning is not built for this duty. Under heavy, often unbalanced loads it runs hot, wears fast, and the vibration shows up in the yarn long before the bolster fails outright.
The answer is a bolster rated for the duty: heavy construction, the right neck bearing, and dynamic balance that holds up under load.
Built for the duty
The Vindex fishnet yarn spindle bolster is rated 3,000–7,000 rpm for fishnet yarn twisting, rope and twine applications. It is built to hold the spindle steady under heavy, often unbalanced loads, with a long working life and low vibration.
The complete assembly comprises the bolster, spindle shaft and blade, upper blade, wharve, insert, nut and washer, spring, tip button and auto hook. The spindle blade is EN-31 / AISI-52100 bearing steel, and the bolster housing is cast iron / alloy steel.
Models covered are HZ-44, HZ-55, HZ-66, HZ-68 and HZ-77, with 20 / 24 / 28 mm neck bearings. Typical working figures from the product specification:
- Typical gauge: approximately 200–406 mm
- Typical twist range: 200–800 TPM
- Typical yarn range: 150D–1000D filament yarn
- Typical package weight: 2–6 kg
Where it runs
The bolster suits fishnet yarn twisting, ring twister, ring doubling, draw twisting and rope / twine twisting machines, including machines from Aawadhkrupa, Laxmi Narayan Industries (LNI), JMW, Huzur Makina, Allma, Minarva, Birko, AS Giesse, Milhan Makina and Meera Industries. Process types covered include nylon rope, twine, polyester yarn and fishing net yarn.
Each machine position has its own geometry, so the machine make and model still decide the exact configuration. A listed model for one machine should not be assumed to fit another.
What to check before ordering
Send the exact machine make and model, dimensions and required quantity with your enquiry, so the correct configuration can be confirmed. In particular, confirm:
- The machine make and model, and the spindle position.
- The neck bearing size: 20, 24 or 28 mm.
- The gauge, twist range and package weight you run.
- The yarn range, from 150D to 1000D filament yarn.
