ITMA 1991 -- SPINNING, WINDING, TWISTING

Long-staple yarn production machinery displayed at ITMA 1991 is reviewed. Tow conversion machines, displayed at ITMA 1991 are reviewed. Tow conversion machines, blending units, carding machines, and drawframes are considered. Seydel surprised the industry with its display of a crush cutting converter that produces quality sliver with a mi..

AUTOMATION OF TRANSPORT IN THE SPINNING PLANT

Neuenhauser's DispoSpin Z100 palletizing unit can be used in yarn package handling and storage. Packages are transferred to a robotic conveyor with a lifting and turning mechanism. At the palletizing unit, a multiple grab engages the packages individually or up to several at a time and deposits them in a pre-determined stacking pattern in..

AUTOMATION IN THE PREPARATORY PROCESSES OF SPINNING

Process automation integrates materials handling, plant operation, optimization of product quality, and economic optimization. In spinning, materials handling is generally automated, except in bale handling and can transportation. Truetzschler has developed the Blendomat BDT 019 for bale handling and the Canny-One for can transportation. ..

ITMA 1991 -- SPINNING, WINDING, TWISTING

Spinning, winding, and twisting machinery exhibited at ITMA 1991 is reviewed. The major trend was toward a fully automated mill. Critical operations to be automated in transport systems and machines are noted. Other important trends were increased production rates in the card, drawframe, and flyer; increased speeds in ring and open end ro..

WASTE IN COTTON SPINNING

The sources of waste lint emissions during yarn production are identified. Waste generation during carding, drawing, and spinning are described. A relationship between fly production and the defect rate in spinning is established. The use of fly removal systems on processing equipment is urged. The development of treatments to improve the..

LAB-SPINNING, HIGH-TECH IN THE LABORATORY

SKF's Lab-Spinner is a spinning machine for use in a laboratory to test new spinning protocols or to design new yarns. The individual Motor Drive System (IMDS) drives the spindles and the drafting unit. All production parameters can be simulated. A servo guide finely coordinates the traverse movements of the ring rail/balloon control and ..

ITMA 1991 -- LONG FIBER (WORSTED YARN, SEMI-WORSTED YARN, AND CARDED YARN) SPINNING

Machinery and equipment for long-staple spinning exhibited at the 1991 ITMA are reviewed. The use of computers with sensors to monitor and control production was the major trend. Many highly flexible and reliable, automated installations were exhibited. High yarn quality, low production and energy costs, and environmental safety were othe..

ITMA 1991 -- SPINNING. PART 2.

Spinning machinery and equipment exhibited at the 1991 ITMA are reviewed. The exhibits of manufacturers of linking systems and bast fiber, open end rotor, and unconventional spinning systems are detailed. Unconventional spinning systems include air jet, friction, wrap, and self-twist spinning systems. SKF has developed a program for retro..

ITMA 1991 -- SPINNING

Spinning machinery exhibited at the 1991 ITMA is reviewed. The recession has affected this sector. Because growth is down, companies have not invested in research and development to the extent required for new technologies. However, some important trends were in evidence at the exhibit. Automation has resulted in high productivity, partic..

TEST ON FIBER SPINNABILITY.

Spinnability and electrophysical properties of cotton, polyester, and polyester/viscose were tested under different atmospheric conditions. The measure of spinnability was the number of breaks for 1000 spindles in one hour.
