This paper introduces design of a strain control system applying in JHML-T1000 complex machine based on PLC. Its core control unit is SIMENS S7-200. Its executors are DC motor and magnetic particle clutch. The system implements constant strain control. All controls include rolling-down control,jointing control,printing control and curling control. The soft -ware of controls is clear in frames with models.
