HISTORY, PRESENT STATE, AND FUTURE OF HIGH SPEED SPINNING.

The development and current status of high-speed spinning are reviewed. Yarn orientation is discussed with regard to fully drawn yarns and higher productivity. Mathematical modeling is used to further improve high-speed spinning. The limitations of spinning at speeds higher than 6000 meters/minute, such as fiber structure formation, windi..

SPINNING OF SHORT FIBERS IN THE YEAR 2000.

Automation, long operating hours, and executives with good business acumen will be critical to managing highly economical, short staple yarn production facilities in the year 2000. The implementation of cost-effective technology will also affect the success of many industrialized countries.

AUTOMATION AND QUALITY KEY SPINNING IN THE 1990s.

A forecast of the status of the spinning industry in the 1990s addresses the effect of electronics on automation and product quality. Productivity and speed will lose some of their significance in a fully automated operation. Spinning systems in general have reached the upper limits for speed; other problems are now considered more critic..

TOWARDS COMPUTER INTEGRATED SPINNING.

Rieter Machiner Works displayed its innovations in spinning automation at Japan's Otemas exhibition. Recent developments include the C 4/1 card, which features a high-quality module attaining an 80 kg/h mill production rate, the D 1/A drawframe offering increased delivery speeds, the Servolap conveying system, and the Robofil spinning mac..

UNITED STATES SPINNING SECTOR -- PROGRESS IN SPEED AND QUALITY.

An overview of the spinning industry in the United States emphasizes investments in technologies to increase production speed and product quality. Ring and rotor spinning are the dominant short staple spinning systems, with limited applications of air jet, wrap, and friction spinning. The properties of cotton grown in different regions of..

SPINNING INTO THE FUTURE.

Drawing, spinning, and winding are linked in automated semiworsted yarn production to increase yarn quality and decrease labor costs. James Mackie and Sons manufactures a system which consists of a semiworsted card and chaingil drawing frame which are automatically doffed. The Rove Draw Finisher is a new finisher chaingill. This preparati..

CREEL SHAPE ENSURES FREE RUNNING OF ENDS.

Hacoba's G 5-V warping creel uses rotating package frames and stop brakes to keep yarn ends tight as the warper stops. The Hacoba creel offers manual knotting for ring spun yarns, automatic knotting for open end yarns, reduced downtimes due to rotating frames, and automatic tension compensation.

WORLDWIDE DATA REGARDING IMPROVED COTTON-TYPE EQUIPMENT.

Technical data on spinning systems and new devices designed for processing cotton-type fibers in spinning mills are reviewed.

INTEGRATION OF THE SPINNING PROCESS.

The spinning process requires more automation to increase profits and keep up with current consumption rates. For example, reducing operator time by automating doffing and roving is imperative. Automating ancillary processes such as cop transfer and yarn piecing is also important. A considerable amount in wages has been saved by automatin..
