Specifications
Cop winding spindles start and stop constantly and handle the package directly — the bolster takes reversing loads that a ring-frame bolster never sees. The HZ-3C is built for that duty: rated 3,000–12,000 rpm, it keeps the spindle steady through long winding cycles. 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.
It replaces the original HZ-3C geometry directly, so winders go back into production with no adaptation. View the product specifications on this page for dimensions and details.
Winding departments that change bolsters on a running schedule — rather than waiting for vibration — keep package build quality consistent and avoid the unwinding faults a wobbling spindle creates downstream.
