AUTOMATIC BOBBIN CHANGER

Textecno Herbert Stein's Model K automatic bobbin changer is capable of operating autonomously or linked with test instruments or capable equipment with no bobbin changers. The Model K can link instruments, which eliminates the need to transfer bobbins. An automatic knotter integrated in the Model K can join the ends of yarns in a wide ra..

BLENDING OF USABLE WASTES

Usable waste produced during spinning includes lap ends, carding sliver, drawing sliver, and in some cases, roving ends. These wastes can be reused in both blow room and drawing/blending using formulae established to set accurate blending parameters. 2 refs.

ECONOMIC BENEFITS OF SELF-TWIST SPINNING

Platt Saco Lowell's Type 888 Self-Twist Spinner has economic advantages over conventional methods of long-staple spinning. Since its introduction in 1970, the Self-Twist Spinner has gained its greatest market penetration in the spinning of knitting yarns from high bulk acrylics. The Self-Twist Spinner produces a two-ply false-twist yarn t..

COMPARISON OF HIGH-PERFORMANCE SPINNING PROCESSES FOR 100 PERCENT POLYESTER FIBERS.

A portion of polyester short-staple fibers are spun as 100 percent polyester for use in women's outerwear, industrial textiles, and fibers and the relevance of the differences to spinning are discussed. Ring spinning, rotor spinning, air jet spinning, and friction spinning of 100 percent polyester are compared. Strength, quality, elongati..

CIM IN THE SPINNING MILL--UTOPIA OR REALITY?

Computer integrated manufacturing will increase the efficiency of spinning mills by reducing personnel-intensive operating procedures, providing for continuous material flow, monitoring manufacturing at each stage of processing, providing numerical control of machines, and networking all data processing systems. Automated systems are curr..

AUTOMATIC BOBBIN SORTING AND LOADING DEVICE AT THE SPINNING FRAME

MLR's HFRM automatic bobbin sorting and loading unit consists of a container tilting device, empty-bobbin container, bobbin sorting and transport device, and a device to transfer empty bobbins into the bobbin infeed device at the spinning frame. Bobbins are transported horizontally from the empty-bobbin container to the bobbin buffer wher..

DUST REMOVAL IN THE PREPARATORY PROCESS BEFORE SPINNING

Dust generated in spinning cotton is a major problem that affects machine performance and the health of workers. Dust levels can be significantly decreased during preparatory processes, such as opening and cleaning, by direct, gentle extraction. Units specifically designed to suction of dust can also be installed at the end of opening lin..

BISPECTRA OF SLIVER IRREGULARITES.

The variations in thickness of slivers drafted with a drawing frame were measured with an evenness tester, and the bispectra of the sliver were calculated. The bispectrum of a mathematically ideal sliver made of fiber of uniform staple length was obtained. The bispectra of a random sliver and two pseudo-random slivers, which were generate..

NEW OPENING, BLENDING, AND CLEANING SYSTEM

Crosrol has developed a new range of opening, blending, and cleaning equipment that is capable of complete bale-to-sliver processing. The large width of the blowroom line results in high throughput and productivity or gentle cleaning with throughput and productivity equivalent to conventional lines. Ease of maintenance is critical to the ..
