Pinned Taker-In
"Fibre
Friendly" Pinned Taker-In Rollers
Stewart developed
the Pinned Taker-In in 1972, and extended use since then has
shown it to be fibre-friendly and extremely durable, making it
an ideal match for TRUTSCHLER High Production Cards, where
quality and output must be maximised, and downtime minimised.
Pins
are fibre Friendly
Cotton has been
traditionally carded using card wire. However, pins with
their smooth pointed shape, do less damage to the fine
fibres. The sharp, but smooth point of the pin
gives excellent fibre penetration. The grain of
the metal and the machining marks of the pin all run
along the axis of the pin, so fibres can float freely
around the point, and there are no traps to catch fibres
or start wear. A reduction in fibre damage and improved
waste extraction are usually found. This can recoup the
cost of a Pinned Taker-In over its first year of
three shift working |

Card wire has sharp edges
which can damage fibres. |

still running well after this demonstration of
longevity, and was only removed for exhibition purposes.

Long
Life
The Pinned Taker-In
is extremely resistant to wear and damage, and a life of
over ten years is common on conventional cards. Many
hundreds have now been installed world-wide, and
although the oldest are 20years old, few have yet worn
out. Life on high production cards is just as
extraordinary, and tests in Germany and the USA have
shown a lifetime of at least 3 years can be expected
with no maintenance at all. Each pin is separately
fixed, so any accidental damage is usually local, and
there is no risk of further damage through the card due
to wire stripping. |
Universal
Pinning
A major advantage of the STEWART
Pinned Taker-In is that one specification of pinning
can be used to successfully card almost all fibres, so
there is no need to change when running different fibres
or blends.
Reduced
Maintenance: Less Down time
Regular card down-time is
saved because it is not necessary to rewire a Pinned
Taker-In. This is particularly important for the
Taker - In. which is usually rewired three times as
often as the cylinder. The pins wear better because of
their points, and they do not need sharpened or ground. |
| Light
weight
The extraordinarily light
weight of a Pinned Taker-In ( approx 40kg),
simplifies fitting without lifting apparatus, and
reduces any risk of personal injury |
STEWART Taker-In = 40kg
Conventional Taker-In = 120kg |
Lower
running speed
The Pinned
Taker-In typically runs best some 20% - 25% slower than
wire, leading to reduced wear, power consumption and
fibre damage. |
Efficiency

Efficiency
of Pinned Taker-In Compared with Wire.
Efficiency is consistently high
throughout the extended life of a Pinned Taker-In.
The efficiency of a wire Taker-In drops so rapidly that
the wire must be replaced regularly.

| The Stewart
Pinned Taker-In is a very worthwhile new development. It
offers major savings due to improved performance and
reduced downtime and is a most effective investment to
enhance your TRUTZSCHLER Card.
