Deviation Correction controllers （web-guide system） play an indispensable role in many industrial industries, mainly used in textile and printing related fields.. Due to the appearance of the deviation correction controller, the industry has been greatly developed.

  Deviation Correction control system is mainly a closed environment, composed of a controller, a linear guide machine and some sensors. Its working principle is:

   First, measure the actual position and offset at the edge of the correction roll material. Note that the offset must have a proportional electrical signal. Next, the electrical signal must be sent to the controller. After these signals are amplified and subjected to some processing, they are transmitted to the driver. Finally, the drive is returning the roll to a preset position.

   Deviation Correction controller can now be widely used in packaging, textile, and other industries. The materials needed are thin film, woven cloth, etc., and it is used in conjunction with printing technology, packaging and non-woven equipment, and has powerful functions.

Following are the related application with deviation correction controllers in LINGTIE machinery .

*Deviation Correction controller assembled in roll to roll screen printing machine

The effective correction feeding is ready for high-precision printing. At the same time, the oven installed in the deviation collection system ensures material recoiled trimly and provides a good material condition for the second overprint.

*Deviation Correction controller was used with rewinding machine

Rewinding machine also popular used in film production and processing ,paper or printed label industry . Deviation correction system as optional function for this kind of machine ,solved the problem when rewind the untidy material .
