Forecast model for stitch length of rib fabric on flat bed machine

A forecast model for the stitch length of rib fabric was established based on observation of the knitting process of rib fabric on the flat bed machine and certain assumptions through analysis and deduction.Feasibility of the model was verified by the comparison between the measured and predicted stitch length of the rib fabric knitted under preset conditions.The results revealed that the stitch length of rib fabrics showed a good linear relationship,respectively,with press depth and needle bed gap.According to the model,scale of the stitch cam on the flat bed machine head can be reset,the problem that the scale is not consistent with the needle depth is solved,the corresponding relation between the stitch length of the rib fabrics with the press depth and needle bed gap,respectively,is established,which is convenient for production control,can quickly determine the stitch length,and provides a basis for yarn budget and cost accounting.
