Garment manufacture lies at the end of the textiles production chain. Here, the individual items of clothing are tailored to the desired size. The accuracy of the cut, reproducibility and high productivity are the key factors in this process. They determine the quality and the cost of the end product.
Starting with a stack of crease-free cloth runs, special software programs are used to define the necessary cuts to minimize material rejects. Then, the cutter is guided across a coordinate table to produce the desired parts. The guidance of the cutter, the special cutting processes at corners and rounded edges and allowance for cutter wear are the machine parameters that determine the quality.
Open and closed-loop control of the cutter therefore plays a key role. The FM 357-2 function module was selected from the SIMATIC S7-300 range for this purpose.
