Factory Acceptance Checks for a Computerized Flat Knitting Machine
Buyers should define measurable pass or fail checks for a 52 in computerized flat knitting machine before shipment, covering stitch quality, carriage speed, and system behavior.
For a factory acceptance test on a computerized flat knitting machine, the buyer should first decide which knitted sample will serve as the reference article, because every later check depends on that agreed swatch. Ask the supplier to knit the same yarn and pattern at the stated 52 in knitting width and at the maximum carriage speed of 1.6 m/s, then compare the result with a slower run.
Useful pass or fail questions include: does the single carriage, two systems machine produce the agreed stitch structure without dropped stitches or unintended tuck loops? Does the pattern repeat align across the full width? Does the machine stop correctly when yarn breaks or the carriage reaches its limits? For each check, define the sample size, the number of repeats, and the acceptance criterion in the request for quotation, and require the demonstration to use buyer-supplied yarn where practical.
Treat the catalog values as reference values only; confirm that the supplied model matches them.
Before requesting a quote, confirm with the supplier which tests will be witnessed, what yarn and pattern data the buyer must provide, how deviations are recorded, and what documentation accompanies the acceptance results.
