Technology Advancements TW Special Report Winding Progress Murata's new-generation Process Coner improves on features of earlier Mach Coner. It is essential that the automatic winder, as the final stage of spun yarn production, be capable of utilizing all of the recent developments in electronic yarn clearers. The automatic winder of the future will need to continuously monitor and manage the operational status of the machine, as well as provide on-line and on-time winding. Customers will require continual improvements in the quality of the yarn. It is to this end that Muratas Muratec Mach Coner, introduced to the international market in 1979, has recently undergone a full redesign.The new winder (#21C) offers many innovations and shows significant improvements when compared with the Murata Mach Coner (See Figure 1):A new winding drum with two distinct pitches on the same drum eliminates ribbon winding and promotes high-speed unwinding at subsequent processes.A straight yarn path and electronic tension manager enable high winding speeds with tight controls on package length.Perla-A and Perla-D devices using compressed air and mechanics respectively reduce yarn hairiness and improve warping, slashing and weaving operations. Coupled with compact spinning, these devices produce a yarn having greater added value.An inverter-controlled blower and direct-drive winding drum reduce power consumption. The blower also reduces operating noise.A kink preventer reduces hard waste, which is automatically separated from soft waste on the #21C model.
