Specifications

Pirn winders feed shuttles and rapiers — and a wobbling pirn spindle means uneven pirns, bad unwinding and loom stops. This spindle and bolster is built for the Murata 303II pirn winder; share your machine model so the Vindex team can confirm the match before quoting. 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.

Weaving mills often overlook pirn winder spindles until loom efficiency drops — a planned bolster change on the winder is one of the cheapest efficiency gains in the weave room.

Do not let the shared specification table mislead you: although this page's bolster family data matches the TFO pages, the Murata 303II is a pirn winder, and its spindles work to a different rhythm — building pirns that must unwind cleanly at the loom, pass after pass. A bolster that lets the pirn spindle wander produces pirns of uneven density; the weaver then meets the fault as bad unwinding and loom stops, far from its real source in the winding room. These assemblies are supplied complete — flange, nut and spindle lock included — and dynamically balanced. Weaving mills planning a winder overhaul should count the spindles per machine and order the full set in one consignment.

Murata 303II Pirn Winder Spindle Bolster — Frequently Asked Questions

Which machine is this spindle and bolster built for?

The Murata 303II pirn winder. Share your machine model when you enquire so the Vindex team can confirm the match before quoting.

Why does the condition of the pirn spindle matter so much?

Pirn winders feed shuttles and rapiers, and a wobbling pirn spindle means uneven pirns, bad unwinding and loom stops. A sound spindle and bolster keeps pirn build even and looms running.

What are the signs the pirn winder bolster is worn out?

Excess vibration during winding, uneven pirn build and poor unwinding at the loom are the usual signs. Replace the bolster before wear starts causing loom stops.

Do you export the Murata 303II bolster in bulk quantities?

Yes — Vindex Industries manufactures at Surendranagar, Gujarat since 1985 and exports in bulk order quantities to mills worldwide. Send the machine make, model, dimensions and required quantity for a confirmed quotation.
