The OPTIMA is a fully computerized chenille machine.
Unlike every other competing chenille machine on the market, all the motors (heads, feeds and spindles) are driven directly by an electronic card. With more than 22,000 electronic cards working worldwide Giesse is an industry leader in the computerized chenille machine field.
Its' computerized control system simplifies operational access. This allows a rapid modification of the working parameters while the machine is operating.
This control system allows for separate, or collective control of the four spindles, making it possible to;
1. Increase or decrease the rotation speed of the spindles, of the feeding rollers and heads, in order to optimize the quality of the yarn and the production capacity of the machine.
2. Choose the rotation direction of the spindles and the heads.
The motor speed is managed directly by inverters with immediate signaling and stopping of the spindle, when an anomaly occurs that changes the quality of the product. As a result, the yarn quality is guaranteed for all the spindles in production, with no additional material waste.
3. Eliminate many of the rotating masses such as pulleys, mechanical transmission shafts, etc. A savings in electrical energy is achieved, when compared to the electromechanical model.
4. Reduce maintenance costs, due to the control and substitution of parts subject to wear and tear (belts, bearings, joints, etc.) and production interruptions.
The main advantages of OPTIMA compared to the electromechanical machines can be summarized as follows:
Higher quality – the software manages the speed of the head, feed and spindle motors. The benefit is consistent and repeatable production over a large range of yarn counts with all materials.
Constant product quality - all the motors are driven directly by electronic card that eliminate mechanical transmission components (shafts, pulleys, belts, bearings etc.) that require periodic check and replacement. Over 30% of the transmission components of the new modular chenille group have been eliminated. The benefits are higher productivity, limited number of broken ends, reduction in waste, reduction in time for a modification of the production cycle, lower maintenance cost.
Particularly, the absence of shafts and universal joints eliminate the problems of wear and misalignment of the production components. The absence of parts to lubricate, as well as the new rotating blade free of pinions and crown wheels reduces to a minimum the maintenance costs guaranteeing a high degree of reliability over time.
One on the main problems of the chenille machine with pulleys and belt transmission is the slippage between motors and devices. Slipping belts may cause differences in the relative speeds of the spindle heads as they spin. This will result in:
Inconsistent product quality of the material
Correction of the problem and setup of the machine
Different yarn count per spindle.
Section by section it is possible to produce different types of chenille yarn. For example, by replacing the upper part of the machine and fitting the Hollow Spindle Modular Kit, the machine can be adapted to produce fancy yarns quickly. This flexibility enables reacting to market demands, with minimal additional investment. No other competitor machine can do this.
