The STEWARTS family of Opening and Cleaning pinned Blowroom Rollers is an integrated range of products all designed to take full advantage of the qualities of aluminium alloy extrusion and long life carbon steel pins. The opening and cleaning blowroom rollers are designed and manufactured to a very high engineering standard and are dynamically balanced before being despatched.
STEWARTS Pins are drawn from high grade carbon steel that is hardened, then tempered and finally, polished. The grain of the metal and the machining marks of the pin all run along the same axis, so that the fibres can float freely around the pin-point, and with no snags to catch fibres there is no wear to the pin.
The working lifetime of a STEWARTS pinned roller has been well appreciated by those who have been regularly replacing card-wire rollers. It is common to find STEWARTS Rollers still running reliably after many years. Pins are ¨Fibre Friendly¨: The smooth, rounded shape of a pin does much less damage to delicate fibres than conventional card-wire. The sharp point of a Pin also gives excellent fibre penetration. The result is exceptional fibre opening with minimum fibre damage, and consequently staple length is maintained. Stewarts ´Fibre Friendly´ Pinned blowroom rollers are now at the forefront of a new generation of blowroom systems.
Each pin is separately fixed so any accidental damage is restricted and there is no risk of the sort of damage caused by wire stripping. STEWARTS has over 135 years of experience solving the world´s fibre processing problems.
STEWARTS Blowroom Rollers are ideal for fitting as Original Equipment or as a simple and cost effective way to upgrade existing machinery. We have designs for most current machines, whether tube-type, multi-lag or three-lag, and can also provide replacement lags and other components for conversions. This range of designs also offers control over air-flow, which is essential for good cleaning.
STEWARTS rollers and lags are designed to be easily fitted to existing machinery, thus providing a very cost effective way to increase efficiency. A wide range of options for conversion can be offered, ranging from individual lags to complete roller assemblies.
