The optical weftstraightener is composed of a reading bridge that, by means of sensors or reading heads, is able to detect the fabric weft distortions; according to this data it will regulate bow and skew roller groups activity, in automatically, without any operator intervention needs.
The machine can have several configurations with two main differences: MDC model and FDC model.
- FDC model without driven bow roller, ideal for woven fabrics since they need higher tension.
- MDC model with driven bow rollers for knitted fabric for a lower tension.
Camera reading system SDD1 (Smart Design Detection)
The system bianco SDD1 is composed of dedicated sensors, similar to cameras and pulsating light sources, the number of which depends on the fabric width. Via dedicated mathematical algorithms, the system is able to detect the distortion of a large number of stripes or patterns on the fabric and to communicate with the correction system of weft straightening machines and/or implementation systems, in order to restore the required alignment.
Its typical application is where the fabric weft is not readable or is preferable to align designs or lines in a periodic pattern of the weft.
The high degree of automation achieved makes bianco SDD1 easy to use by operators, avoiding complex settings typical for other reading systems. Its versatility also allows some flexibility for adaptation to specific needs and fabrics.
