Specifications

The Muratec 363 air-threading variant adds pneumatic threading passages to the bolster — a geometry more demanding than the standard 363. This air-threading bolster is built to the 363 air-threading profile so threading stays crisp and doff cycles stay short. 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.

Weak air-threading is often a worn bolster, not a machine fault — if threading needs repeated attempts, the bolster seating and passages are the first things to check.

Air threading changes what a bolster has to be. On the 363 air-threading variant, the bolster carries pneumatic passages that blow the yarn through at threading, so its internal geometry is more demanding than the standard 363 bolster's — and the two are not substitutes for each other. When threading weakens, work through the air path in order: supply pressure first, then passage blockage from lint and oil mist, then the bolster seating itself. Passage condition is also why this variant should be ordered by its full name — Muratec 363 air threading — and not simply as a 363 bolster; Vindex confirms the air-threading profile against your machine details before quoting, so the replacement threads as crisply as the original.

The air-threading variant adds pneumatic threading passages to the bolster — a geometry more demanding than the standard 363. It is built to the 363 air-threading profile so threading stays crisp and doff cycles stay short.

Which Muratec machines does the 363 air-threading bolster fit?

Muratec 363 TFO twisters with air-threading equipment. Because the air-threading passages make the profile more demanding, share your exact machine model so the team can confirm the match before quoting.

What maintenance does the air-threading bolster need?

Keep the pneumatic threading passages clean and free of fluff and oil residue so threading stays reliable. As with any TFO bolster, watch for rising vibration or noise as signs of wear.
