Specifications
Ring doublers twist plied yarns on heavy packages — and the extra-heavy-duty spindle range (HZ-55, HZ-66, HZ-68, HZ-77 and neck-bearing configurations) is built for exactly that punishment. Doubling loads the spindle harder than single-yarn spinning, so the bolster must keep the spindle steady under sustained heavy duty. Vindex Industries manufactures this spindle bolster since 1985 at Surendranagar, Gujarat, exporting it to spinning and twisting mills in 87 countries in bulk order quantities.
Each configuration is made for its listed machine model; the team confirms the match before quoting. View the product specifications on this page, then send an enquiry with your doubler make and model for a confirmed match.
Doubling mills that match the spindle to the package weight — rather than running one bolster for everything — get longer bolster life and more even twist in the plied yarn.
