ADVANCED KNITTING TECHNOLOGY MER4Elastan Roller: Process-safe working with lowest yarn tensions at highest machine speedsThe MER 4 is a universal elastane roller designed for the positive feeding of plain elastane yarn to large-diameter circular knitting machines. This new version of the elastane roller has been developed to process plain elastane at even lower yarn tensions. Especially at very high machine speeds, the completely newly developed sensor unit Performance (P) stands out. The sensor units have no electrical components and are easy to clean. Considerable increases in production ratings can be obtained by fitting the cost-effective optional cover. ADVANTAGES ■ Available with sensor unit Standard (S), Roller (R) and Performance (P) ■ Completely newly developed sensor unit system Performance (P) which ensure working with lowest yarn tension also at highest machine speeds. This is characterised in particular by improved sliding and gliding properties of the yarn deflection bolt and the more compact design which is less susceptible to contamination. ■ Highly versatile. The unit has a single ratio only and is therefore suitable for all current machine types. ■ Compact dimensions, minimum space requirement. ■ High-visibility central warning light. The operator sees warnings sooner, this cuts yarn breakage downtime and increases knitting machine production rates ■ The automatic, adaptive electronic shutdown system is integrated into the shutdown current circuit.

COVER (optional) The shutdown system operates using the force of gravity. If the yarn breaks, contactless magnetic force trips the shutdown system. There are three different sensor units available. The warning light is mounted in a central, highly visible position. Yarn breakages are indicated by a colour change.
