PROBLEM TO BE SOLVED: To stabilize weft beating by taking advantage of an opening apparatus for driving a heddle by an opening driving motor independent from a weaving machine driving motor. SOLUTION: A pattern control apparatus 31 sends a pattern to a weaving machine control computer Co. An opening control apparatus C3 consists of an open curve forming circuit 38 for forming an open curve, a control circuit 39 for reading an open curve from the open curve forming circuit 38 and outputting a control order and a driving circuit 40 for subjecting an opening driving motor 34 to feedback based on the control order from the control circuit 39. The weaving machine control computer Co sends weft density information contained in the pattern to the open curve forming circuit 38. When the weft density information is sent to the open curve forming circuit 38, the open curve forming circuit 38 forms an open curve so that the open curve can be read by the control circuit 39. |
