Dis-continuous treatment of open-width fabrics

With over 60 years of experience and thousands of machines sold throughout the world, Mezzera is in the ideal position to supply a range of jiggers for all needs, from the smallest jigger for sampling to the jumbo machine including all intermediate sizes. The Mezzera jiggers are the outcome of the long experience acquired working on the field.

Drive system

The jigger is equipped with two separate electric motors with variable speed driven by independent AC vectorial inverters.

Speed adjustment

The circuit that controls the speed uses a high resolution encoder. It ensures accurate adjustment despite the change in the diameter of the fabric roll.

Tension control

The required tension can be set in the PLC accordingly 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 a feedback signal to the PLC; set value and measured value are compared and the difference, if any, is immediately set to zero synchronizing the A.C. motors through the inverters. That is done automatically and this system provides a very fast and accurate compensation of any tension fluctuation which may occur during the cycle. Thus, tension applied to the fabric permits to process delicate fabrics (including bi-stretch) with the same tension all over the cycle.

Equalizer

When treating delicate fabrics, thus very sensitive to the applied tension, a central equalizer swingarm, positively driven, is used, whereas for medium-heavy fabrics an oscillating equalizer is applied. Both solutions perfectly aid the fabric to be rolled/unrolled onto the winding rollers.

Liquor circulation- heating

The liquor circulation unit consists of a pump and two pipes, one suction pipe and one delivery pipe, positioned at the bottom of the main tank. The liquor circulation unit has been designed to keep treatment liquor flowing all times, so that the chemical products are perfectly mixed together and to ensure a perfect and uniform dyeing. Both direct and indirect heating system, based on a steam pipe inside the vat, ensures fast temperature control, saving production time and steam consumption. The external heat exchanger is also available on demand. The chemical products are prepared in an external tank which has its own direct heating pipeline, a circular washing pipeline, filter and a discharge on/off valve.

Washing and rinsing

A special technical execution permit to wash and rinse in countercurrent, ensuring an effective washing action with significant advantages in terms of water consumption. The washing effect is increased also thank to 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.

Control system of dyeing process

The control system is based on a state-of-the-art PLC installed in a watertight cabinet. This unit is controlled from an ergonomic control panel with touch screen that allows to save the working cycle, into the PLC, recall and execute the cycles whenever is necessary.

HT JIGGER

THE LAST GENERATION OF PRESSURED JIGGERS FOR HIGH TEMPERATURE DYEING

The forty years of manufacturing experience together with the highest production technology have led to design and to product the most recent jigger in the Mezzera production line. The jigger is available in four versions: 500,800, 1050 or 1300 mm as maximum diameter of the winding fabric rollers. The dyeing quality is blended with totally safe high temperature operation up to 143°C.

The jigger is equipped with two electric motors with variable speed independently controlled by vectorial inverters. The tension value applied on the fabric is controlled by the two synchronized motors through encoder and mathematical models on the PLC. The real fabric tension value during production is checked by the load cell, located in one of the two cylinders at the bottom of the tank. The swing-levers have been designed to obtain crease-free dyeing in even the most delicate fabrics.

The tank, in stainless steel, and the operating methods have been designed to reach the highest washing efficiency. The jigger is equipped with an axial fabric unloading system. To make fabric winding easier without getting any folds or crease a device, made up of a fixed fabric-expanding bar and an idle guide roller, has been fitted onto the machine.bi-stretch) with the same tension all over the cycle.
