This application is normally used in paper printing, textile printing or synchronization is the need of the application. Separate motors are used to control individual rollers.
Application requirements
Precise registration sensing and synchronization
Multicolour printing
Tension control
Accuracy in printing
Features
Precise position synchronization of individual rolls
Registration mark sensing
Higher line speed
Encoder feedback for dancerless tension control
Built-in PLC for process interlocks
Elimination on unwinder brake
User friendly man-machine interface
Application SolutionIn the scheme offered the draw roller is preciesly controlled by a vector controlled AC induction motor or by a servo motor. Precise position control is achieved through encoder feedback. Build-in PLC I/O's are provided for syncronized process operation and saftey interlocks.
