SLIVER CAN TRANSPORT BY PUSH-TURN ROD SYSTEM.

Innovatex's Canny automatically transports full and empty sliver cans on rail tracks. These tracks are placed only 32 millimeters from the floor, are wear resistant, and have low frictional characteristics. The system is simple to install, requires little floor preparation, and operates with minimum maintenance.

SEMI-WORSTED SPINNING LINE LOOKS TO THE FUTURE.

Lummus Mackie has developed a system for automating preyarn processing on semi-worsted spinning lines. The system consists of a card with draw head, two Speedmack chain gills, and two automated Rove Draw Finisher spindle drawframes. The drawframes feed eight Ringtron ring spinning frames, which are linked to automatic winders. The system ..

TOWARDS AUTOMATION IN PRE-SPINNING.

The process of converting bales of fiber into sliver suitable for spinning involves opening, carding, drawing, and combing. Before the end of the twentieth century, the development of a fully automated bale-to-sliver fiber opening and preparation system is expected. There will also be significant improvements in the quality of carded yarn..

POSITION OF THE MAIN DRAFTING IN A DRAFTING SYSTEM.

The relation between ideal and real draft and experimental studies of fiber movement in the drafting system is formulated. The position of the main drafting point must be known if drafting controls are to be effectively mastered. 21 refs.

PROPOSALS FOR AUTOMATED FEEDING OF ROVING BOBBINS IN WORSTED YARN SPINNING.

An acceptable solution for the automated feeding of roving bobbins in worsted yarn spinning mills has not been developed; however, several ideas for solving this production problem are outlined. 13 refs.

YARN TWIST AND FABRIC USE CHARACTERISTICS.

EFFECT OF SLIVER PREPARATION ON FIBER DISORDER AT ROTOR GROOVE.

The configuration of fibers in the rotor groove is characterized in terms of proportion of curved fiber ends, coefficient of relative fiber parallelization, and the degree of straightening of curved fiber ends and fiber parallelization. The effects and influence of drawframe passages on the configuration of fibers in the rotor groove are ..

FIBER SPINNING -- 1989 INVESTMENTS AND WORLD CAPACITIES.

The year 1989 was marked by a slight downward trend in fiber spinning after a record year in 1988. World deliveries, not including material produced in the Soviet Union and China, declined 2.75 percent in short fiber spindles, 13.5 percent in long fiber spindles, and 5 percent in rotors. Globally, short fiber ring spinning progressed to t..

SPINNING IN THE 1990s.

A discussion of the market requirements for spinning systems in the 1990s focuses on economics, automation, yarn quality, and flexibility. The technological merits and limitations of the most promising spinning systems are analyzer by theoretical and experimental considerations. A comparison of these systems provides the probable applicat..

SPINNING FOR FUTURE SUCCESS.

The success of any cotton spinning mill depend upon yarn quality. Eventually, cotton yarn will not be designated as carded or combed, but sophisticated cleaning equipment using doffer rolls will select fiber by length. Sliver quality and preparation will be increasingly important as more manufacturers eliminate the roving stage and spin d..
