Mezzera offers Concorde, which represents the ideal improvement in the field of textile machines for the treatment of woven and knitted fabrics in rope form. The uses have grown impressively thanks to the reduced consumption and to the limited pollution in the waste water.

Given the current market with such a great emphasis on production dynamics, the Concord represents a compact machine with low consumption, high washing efficiency and great operating flexibility especially for items with a weight of between 50 and 700 g/mi.

The fruit of Mezzera's many years of experience in designing and manufacturing machines for the wet treatment of fabrics, this innovative machine is ideal for the preparation treatment of goods from artificial and synthetic fibres, for the neutralising treatment of fabrics after mercerising or causticization, the relaxing treatment of fabrics, treatment of Lycra goods and for washing after bleaching, dyeing and printing.

Concord has been on the market for a number of years, as testified by the indisputable sales success. In terms of flexibility and quality assurance, it represents a technological revolution in washing in rope form (a treatment method that Mezzera was the first to introduce when they launched the Niagara model). Furthermore, tapping the experience its predecessors gained on the field, the Concord is reliable even for bleaching open and tubular knitted fabrics.

Completely built of stainless steel, the Concord consists of a number of channels (8 to 16) of increasing capacity and, thanks to the re-design of the fabric feed pipes, can reach a higher working speed. From a technological aspect this machine can be divided into four or five sections depending on the special production requirements.

While moving from one channel to the next, the fabric is efficiently washed and then squeezed to remove some of the polluting waste water, on the one hand, and to intensify the washing action on the other. The liquor undergoes counter-current flow between channels of the same section but it is possible to deliver liquor from one section to another according to specific technological requirements.

Thanks to the overflow system, which guarantees transport, the fabric moves ahead constantly immersed in the liquor and totally tensionless.

Each section is independent. Each channel has its own temperature control device, water and chemical-product inlet valve into the treatment liquor, heat exchanger, circulation pump and an interchangeable filter. The re-designed squeezing rollers are located in a new functional position to remove fabric-sliding or weft-opening problems.

Drive comes from independent inverter-controlled AC motors to ensure perfect synchronisation and continuous speed adjustment without any risks. Each channel has its own control unit to keep the pre-set quantity of fabric constant, thus ensuring equivalent dwelling times for the whole batch. Each channel can hold 500 litres of liquor and up to 50 kg of fabric.

The Concord washing machine control system is based on a state-of-the-art PLC, which accurately controls the fabric speed and the treatment parameters such as water, chemical product and steam dosage. The features chat make this machine a point of reference on the market are:

•  Maximum working temperature up to 98°C.
•  Maximum speed 100 m/min that is an average reduction speed of 85 m/min.
•  Water consumption from 4 to 12 litres per kg of treated fabric.
•  Low energy consumption.
•  Intense and efficient interchange between liquor and fabric.
•  Simple and intuitive control system to set most important operating parameters.
•  Automatic chemical-product dosage inside each channel.
•  Reverse fabric running device for each channel.
•  Telescopic liquor level adjustment mechanism per each section.
•  Either direct or indirect steam can be used to heat the liquor.
•  Heat recovery system.

The Concord machine technologically meets the solid design and manufacturing traditions that have always characterised Mezzera. Thus the inverter controlled drive system. Fabric transportation by oveflow action, automatic control of the process, completely stainless steel manufacturing and the ergonomic design are al1 features chat testify to the effort employed to produce a product that is easy to operate and accessible for the machine operator and the maintenance worker.
