Trace every cone back to its bale lot, mixing plan and ring frame.

A spinning mill turns fibre into yarn. Cotton or polyester bales arrive with a lot number and a fibre test, and they leave as cones in a given count, twist and package weight. Every step changes the quantity, so the mill keeps a running account of waste.

Orders are taken by count and quality. One buyer wants a combed count, another wants polyester blended with viscose, and both set tolerances for evenness, neps and strength. The mill must show a test report for each lot it sends. Buyers ask for it.

The mixing room lays down bales by lot to a mixing plan. The blow room, cards and drawing frames follow, and each department weighs its own production and waste. Supervisors write sliver weights and hank readings on a sheet beside the machine, and the clerk copies the figures into a daily production register that the manager reads the next morning.

Roving goes to the ring frames, where spindle breaks, count variation and doffing set the pace of the day. Winding turns bobbins into cones, clears the faults and fixes the package weight. The lab tests evenness, strength and imperfections on samples drawn at the frame and at the winder.

Finished cones are packed by bag or carton, with lot, count and net weight marked on the label. A despatch clerk checks the packing list against the buyer’s order. The test report goes out with the invoice. Nothing leaves unlabelled.
