What is the purpose of the hose binding machine?

It is used to tightly wrap wire around a fire hose over the tailpiece of a coupling, securing them together to withstand high water pressures without leaking or detaching.

What hoses are usually bound using this machine?

It is primarily designed for standard fire delivery hoses (like those covered under IS 636), typically 63 mm in diameter.

What type of binding wire is recommended?

The code typically recommends galvanized steel or copper wire to prevent rusting that could degrade both the binding and the hose fabric.

Practical Notes

Ensure the tensioning mechanism is correctly adjusted; too much tension can cut the hose fabric, while too little will cause the coupling to blow off under pressure.

Always use the specified gauge of galvanized or copper wire to prevent premature corrosion and failure of the binding.

Regular lubrication of the chuck and spindle is critical to maintain smooth winding operation.
