(Auto Feed and Auto Pleat Calculation Module) Equipped with “Automatic Curtain Pleat Calculation Module” that allows operator to input the curtain panel’s original width, pleat’s numbers, preferred pleat distance and some other parameter, as well as the targeted finished width after pleating on the Touch Screen control panel. Then the computer module will automatically calculate the parameters based on the operator’s required measurement and then the pleating device will adjust automatically depending on the parameters from the curtain pleat calculated values. The machine also adopts the same pleating mechanism of the S-CT250 “Automatic Feed Function”. The pleating will be done automatically, and after the materials have been pleated, it will be pushed and fed towards the sewing frame for stitching process automatically. Therefore, the pleating result will be more consistent and uniform evenly It can easily be adjusted by removing or adding pleating metal to do either single, double or triple pleat. The pleating device is independently controlled by a separate PLC unit that has been programmed to be synchronized with the sewing control system. The rest of the electrical components are Schneider contactor units and Mitsubishi Electric Inverter unit.
