| Integral
construction, advanced design
The STEWART family
of 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 rollers are designed and manufactured to
a very high engineering standard and are dynamically
balanced before dispatch.
STEWART 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 solid-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. |
A pin-point penetrates
fibres smoothly.
Card-wire can have sharp
edges to damage fibres.

Pins
are Fibre-Friendly
The smooth, rounded shape
of a Pin does much less damage to delicate fibre than
conventional card-wire. The sharp point of a Pin also
gives excellent fibre penetration. The result is
exceptional fibre opening with minimum damage |
Cleaning Cotton
Cotton Bales are
typically delivered with highly fragmented particles of
dirt trapped by and stuck to the fibres. As this foreign
matter can only be removed from the fibre surfaces,
repeated new surfaces must be exposed to continue the
cleaning process. the STEWART family of pinned rollers
clearly fulfils this role, and it is now believed that
the first opener and cleaned of a blowroom line should
be a pinned roller.

Pins
give long life
STEWART Pins are drawn from high grade carbon steel,
hardened and tempered and then polished. The grain
of the metal and the machining marks of the pin all run
along its axis, so fibres can float freely around the
point, and there no snags to catch fibre or start wear.

Subsequent
Carding
Material processed over
pinned blowroom rollers is thoroughly opened and
therefore in an ideal state for subsequent carding
Upgrading
Existing Machinery
STEWART 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.
"N.I.F."
Bonded Pins
The STEWART development
of "N.I.F" bonded pins allows an unrivalled
pin-point accuracy. This construction eliminates
the distortion caused by pins being force fitted, and is
accurate, strong and lightweight great resistance to
damage.
Resistance
to Damage
Each pin is separately
fixed so any accidental damage is restricted and there
is no risk of further damage caused by wire
stripping. If local damage does occur, it can
usually be repaired using our special repair kit. |
Extruded Hinge
The patented STEWART
"quick change" extruded hinge means that Lages
can be replaced while the roller is still in the
machine, and further reduces the number of fixing
screws needed. This simplifies maintenance and
reduces expensive downtime |
The "quick
change" hinge allows easy replacement of lags |
