- Industrial control systems for steel, corrugated, textile, printing, labeling, paper, plastic film, building materials, cables, rubber, tires, etc.
Guide control refers to the technical operation of the coil produced by the manufacturer during the spraying, printing, punching, laminating, slitting or other coil winding process, always keeping the sides of the coil neat and consistent. Because the edge of the coil is not aligned, it will cause subsequent step errors, resulting in material waste or downtime adjustment. Therefore, when processing the processed coil, it is necessary to perform a timely correcting operation on the offset coil, which is called rectification. The entire process of the device constitutes a set of guide systems.
Web guide systems are extremely diverse and are essential in the packaging, printing, labeling, construction materials, pulp, household paper, plastics, garments, cables, metal processing, nonwovens, corrugated paper processing and other industries. A typical correction system includes a guide controller, a guide sensor, a guide frame, and a driver.

The role of the guiding device
In order to ensure the lateral position of the printing material before entering the printing unit, the unit type flexo printing machine often adopts an automatic rectifying device, which can detect the deviation of the lateral position of a certain edge of the printing material and correct it in time, with an accuracy of ±0.5 mm. . Generally, photoelectric sensors are often used for opaque materials such as paper and aluminum foil, and ultrasonic sensors are used for transparent materials such as films. Once the printing material enters the printing area and the die-cut rewinding area, the horizontal position is stabilized, which is ensured by the processing and mounting precision of the machine itself and the parallelism between the rolls.
