• Drive system: The jigger is equipped with two separate electric motors with variable speed driven by independent AC vectorial inverters.
• Tension control: tension can be set in the PLC according to the fabric specifications. The load cell, positioned on the back-roller under the liquor, measures in real-time the tension applied to the fabric and sends the value to the PLC. The set and measured values are compared and the difference, if any, is immediately set to zero, synchronizing the AC motors through the inverters. The fast and accurate compensation of any tension fluctuation that may occur allows you to process delicate fabrics (including bi-stretch) with the same tension throughout the cycle.
• Liquor circulation – heating: the liquor circulation unit has been designed to keep treatment liquor flowing at all times, so that the chemical products are perfectly mixed together and to ensure a perfect and uniform dyeing. Both direct and indirect heating systems ensure fast temperature control, saving production time and steam consumption. An external heat exchanger is also available on demand. Chemical products are prepared in an external tank that has its own direct heating pipeline, a circular washing pipeline, a filter, and a discharge on/off valve.
• Dyeing process control system: the control system is based on a state-of-the-art PLC installed in a watertight cabinet. The ergonomic control panel with touchscreen allows you to save the working cycle into the PLC, and recall and execute the cycles whenever necessary.
• Speed adjustment: the circuit that controls the speed uses a high-resolution encoder to ensure accurate adjustment despite the change in the diameter of the fabric roll.
• Equalizers: a central equalizer swingarm is used when treating delicate fabrics that are sensitive to applied tension. An oscillating equalizer is applied for medium to heavy fabrics. Both solutions aid in the fabric being rolled/unrolled onto the winding rollers.
• Washing and rinsing: a special technical execution permit to wash and rinse in countercurrent ensures an effective washing action withsignificant advantages in terms of water consumption. The washing effect is increased with a twin set of spray pipes (positioned on each side of the swing lever) to generate a blade of water with an efficient washing effect.
