Description: The electronic let-off and take up controller offers the best control and retrofit option for air jet and water jet weaving machines of different makes like Dornier, Tsudakoma, Nissan, Toyoda, Sulzer and Himson. It is a great value addition and certainly a viable alternative to buying a new machine. The mechanical let-offs uses a combination of clutches and brakes. The wear, play and backlashes of these mechanical parts results in irregularities in density and is unable to meet ever-demanding quality conscious customer's requirement. Regarding electronic let off control the electronic motor driven let off supplies the loom with the necessary warp yarn, maintaining the yarn tension constant from full beam to empty beam. Let off speed is automatically calculated in context with loom speed, weft density, warp beam diameter and close loop tension control. Precise synchronisation with main motor in forward and reverse direction plus special advance features help greatly to reduce the start and stop marks thus, increasing the grade and quality of the fabric. It also makes cramming/density variation design possible. Electronic take up control is an extension option for let off. The let off and take up is synchronized rigidly with main motor in forward as well as reverse direction. With the take up electronic system the weft density variation does not require any more mechanical interventions on the loom, it just requires setting parameters on the fly of the key. The precision in settings and functioning, offers an easy way to adjust weft density for optimum fabric weight and minimum yarn consumption. The electronic Let-Off and Take-Up synchronization opens up whole new era of options for the weaver to manage the fabric marks and quality. The PC connectivity and Internet options offer loom data monitoring locally or from remote place and e-Hub for SPC and analysis.
