Investigation of Profitability threshold of Various Control Techniques for the Devices in Garment Manufacture

The investigation has been initiated by the need to obtain technical-economical basis for a proper choice in finding an optimal technical solution for the control of automatic devices and equipment in garment production machines. Results of profitability threshold studies for various control techniques (with pneumatic elements, relays, PLC) in conventional situations indicate that even in the case of relatively few functions (~7) pneumatic control should be substituted with relays, and with the average number of functions (~12) PLC should be employed, as its price has been constantly reduced.
