The width control system for the packaging industry combines both the Layflat and Ultrasonic control. It computes the width correct to the nearest 0.1mm. A control action proportional to any error is initiated via the TSM Air Correction Unit, via a fixed air supply or radio control link. This system in particular is suited for stretch film lines, where layflat is smaller than bubble measurement value. The systems not only maintain set film widths & chosen tolerance ranges at minimum levels, but they offer a complete package that reduces waste during start up, prevents width fluctuations caused by temperature changes and is expandable and upgradeable. Furthermore it offers shorter start up and change over periods. It is suitable for all blown film line configurations up to 10m in diameter. Different film types/colours are not an issue. Optional Protocols are RS232/485, MODBUS and TSM protocol. Further options include remote width readout module, radio control compressor unit and standard serial/parallel printer link.
