Demonstrating a Computerized Flat Knitting Machine on Your Own Yarn
A buyer's guide to planning a flat knitting machine demonstration around the buyer's actual yarn, with practical checks for a request for quotation and acceptance test.
Ask the supplier to run the demonstration on your own yarn, not a mill sample, before you accept the knitting width or carriage speed as suitable. Yarn count, twist, and elasticity can change how a machine feeds and forms stitches, so a trial on your material is the only practical way to judge fit.
For the request for quotation, specify the yarn you will use and ask for a demonstration piece in that yarn. Compare how the single carriage, two systems handle your yarn at the stated maximum carriage speed of 1.6 m/s and at slower settings. Ask whether the 52 in knitting width is measured under your yarn's tension, and request a sample panel at that width. In the acceptance test, agree on the fabric quality checks, the number of courses and wales, and who supplies and pays for the yarn.
Before requesting a quote, confirm with the supplier which yarns were used in prior demonstrations, whether your yarn can be run without modification, what sample fabric you will receive, and how the acceptance test will be recorded.
