Abstract (en)

A control circuit 34 retrieves a shedding pattern for each of heddle frames 151, 152, 153 and 154 from a weave information memory device 27 for every single rotation of a weaving machine. The control circuit 34 selects a shedding curve for each of the heddle frames 151, 152, 153 and 154 from a shedding curve memory circuit 33 on the basis of the thus retrieved information. A control circuit 34 outputs control command to a drive circuit 35 so as to form the shedding curves thus selected. The drive circuit 35 oeprates shedding drive motors M1, M2, M3 and M4 so that the heddle frames 151, 152, 153 and 154 establish respective shedding curves selected correspondingly. <IMAGE>
