Controlling to Fabric Density (CPI) vs. Fabric Weight (GSM)
Chart 1 shows the results from 44 rolls of fabric for which punch-weight measurements were used to setup machine operation.
Infrequent weight measurements do not provide enough information for the operator to compensate for varying yarn counts or fabric density changes due to prior processes. The finished fabric varies widely, and many rolls are overweight - an unnecessary expense and loss of revenue.
