"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.
PİNS ARE FİBRE FRİENDLY
____________________
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
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.
ÇReduced 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.
LİGHT WEİGHT
_____________
The extraordinarily light weight of a Pinned Taker-In ( approx 40kg), simplifies fitting without lifting apparatus, and reduces any risk of personal injury
LOWER RUNNİNG SPEED
_____________________ The Pinned Taker-In typically runs best some 20% - 25% slower than wire, leading to reduced wear, power consumption and fibre damage.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.
COTTON BLOWROOM ROLLERS (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
PİNS ARE FİBRE-FRİENDLY
_________________________
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
CLEANİNG 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.
PİNS GİVE LONG LİFE
____________________
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 CARDİNG
_______________________
Material processed over pinned blowroom rollers is thoroughly opened and therefore in an ideal state for subsequent carding
UPGRADİNG EXİSTİNG MACHİNERY
________________________________
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 PİNS
_______________________
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.
RESİSTANCE 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 HİNGE
_________________
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
