SIRO-SPUN CHARACTERISTICS.

The effects of spinning parameters on the properties of cotton yarn spun on a ring spinning machine and a Siro-spinning machine were examined. The ring spinning machine (Spintester) was modifed during the test to perform like a Siro-spinning machine. The ring rail scale, total draft, twist, break draft, and spindle speed were varied. Yarn..

AUTOMATION OF TRANSPORT IN THE ROTOR SPINNING PLANT

Components of automated materials transport systems in rotor spinning mills are described. Systems for transporting cans from drawframe to drawframe and from drawframe to rotor spinning machine are discussed. Cans are transported from drawframe to spinning machine using specially designed and arranged cans and either continuous conveyor s..

CERIFIL DEBUT.

S Bigagli's new Cerifil process offers increased production rates and yarn quality and reduced production costs. In recent trials, the Cerifil system has resulted in increased production rates (by 50 percent compared with woolen ring spinning systems), reduced tension throughout the yarn-forming path, fewer end breaks, reduced yarn fricti..

EFFECTS OF VARIOUS TREATMENT ON COTS TO REDUCE ROLLER LAPPINGS.

Treatments that are given to cots to reduce roller lappings during the spinning of cotton were examined. The influence of front top roller pressure and front top roller diameter on the incidence of roller lap-ups was investigated. Combed cotton yarns were

TRANSPORT AUTOMATION IN SPINNING PREPARATION.

Automated materials handling equipment for spinning preparation can reduce costs and increase competitiveness. Criteria for designing a materials transport system for spinning preparation include process- and production-related factors and machine flexibility. The design and advantages of floor-mounted conveyors, suspended conveyors, mech..

USE AND ECONOMICS OF FREELY PROGRAMMABLE ROBOTS FOR PACKAGE HANDLING

Optimization of yarn packages for dyeing, twisting, or other processes is frequently required. Schaerer, Schweitler, and Mettler has developed the Robomat, a freely programmable robot that automatically handles yarn packages. The robot, which is suspended from a track, is capable of changing yarn packages on winding machines. Its function..

AUTOCORO SYSTEM 238 PUT INTO ACTION AT LAUFFENMUEHLE

Lauffenmuehle is a spinning, weaving, and finishing company with annual sales of DM 350. It produces quality outerwear, hih fashion, and industrial fabrics. It now operates 32,000 ring spindles, two-thirds of which are directly linked to Schlafhorst's Aut

BOBBIN TRANSPORT WITH "CERTIFICATE OF ORIGIN."

Duercopp Adler's Transconer is a suspended conveyor developed for transporting bobbins in spinning and doubling mills. The Transconer transports the bobbins from the automatic coner or from the spinning machine to the packing area or the two-for-one twister. The Transconer can be used to control and trace materials flow in the spinning mi..

SUSTAINING BRAIDING TENSIONS.

United States Surgical Corporation has developed a braider bobbin top hold specifically designed to handle fine yarns used in sutrues. The braid is constructed of a tubular or spiroid braided sheath formed about a central core. The carrier is designed to feed yarns into the braiding zone with controlled tension. The yarns come together at..

LUBRICANT-FREE SPINNING.

Allertex's Ban-Oil is an irreversible treatment that completely transforms the structure of the porous metal so that ring spinning and twisting frames can operate wighout lubrication. The rings have a potential life expectancy of up to 30 years. Ban-Oil eliminates the somewhat reduced as a result of the reduced friction between ring and t..
