COMPUTER BLENDS. PART 5. REFINEMENTS AND COMMERCIALIZATION OF COMPUTER BLENDING.

The computer blending technology developed at WRONZ has become a commercially viable system for producing blends for sale to New Zealand and other customers. A study of the length-after-carding properties of New Zealand wool resulted in the addition of new length parameter predictions by the CONVERT subroutine. The INVERT system for class..

COROLAB SYSTEM FRO AUTOCORO ROTOR SPINNING MACHINES.

With the Corolab Schlafhorst has developed a yarn monitoring system for rotor spinning that fulfills all of the requirements of continuous checking of the yarn. The permanent testing of the yarn at each spinning position provides information on yarn quality during the spinning process. Corolab checks the yarn by means of infra-red light, ..

CURRENT DEVELOPMENTS IN SHORT-STAPLE SPINNING.

The four methods of short-staple spinning in commercial use at present are ring spinning, rotor spinning, friction spinning, and air-jet spinning. Each of the four methods is fighting for a share of the short-staple spinning market. The technical limitations of each method remain to be seen, and it is unclear whether ring-spinning can hol..

USTER RINGDATA--QUALITY, PRODUCTION MONITORING FOR MODERN RING SPINNING.

Zellweger Uster's Ringdata quality and production monitoring system provides continuous on-line monitoring of quality and production data in an easy-to-read format. Production reports contain information such as pounds produced, pounds per spindle hour, efficiency, and stop times. Quality reports provide such information as end breaks per..

SUESSEN--NOVIBRA NOISE ABSORBING SPINDLE ASSEMBLY (NASA) SPINDLE TO REDUCE SPINNING NOISE AND ENERGY.

The Suessen-Novibra NASA applies the principle of impedance barrier to reduce the amount of vibration transferred to the spindle rail by the spindle, thus resulting in a spindle that operates more quietly than those of more conventional design. The shaft diameter of the spinning spindle has been reduced from the common 7.8 millimeters to ..

WEARING TEST FOR ROTORS OF SPINDLELESS SPINNING MACHINES.

SPINNING CANS FOR THE AUTOMATION OF THE CAN TRANSPORT.

Gmohling of Furth offers spinning cans which are extremely durable and dimensionally stable, and thus suitable for automated can transport systems. The cans are made of antistatic polyethylene, welded with a smooth seam, and reinforced with steel upper and base rings. The translucent polyethylene allows the filling level of the cans to be..

ONLINE QUALITY CONTROL IN PREPARATORY SPINNING WITH THE DATA COLLECTION SYSTEM USTER SLIVERDATA.

The Uster Sliverdata quality control system monitors the spinning process and reports any manufacturing faults. The hardware associated with this system is reported in detail.

SAVIO--TWINSPLICER MECHANICAL YARN SPLICER.

Savio's Twinsplicer is a mechanical yarn splicing system for splicing ring-or open end-spun 100 percent cotton staple singles yarns. The unit can make splices on yarn counts as fine as Ne 90, and on staple lengths up to 40 millimeters.

AUTOMATION OF YARN TRANSPORTS.

There are many applications for automation in the different stages of spinning. The applications discussed include systems for the conveyance of carding and combing can, roving frame bobbins to the spinning frame, and cops to the winders, and automatic palletization.
