Page 3. WHAT BUYERS ASK The five questions buyers ask first Each answer in this file is a photo, a drawing or a measured value from a real order. Buyer question What we show you Pages Will it fit my existing sprockets and drum? Your sprockets and drum are the reference; the drum test and the belt on the sprocket. 6, 10, 18 Will the new belt match my old one? New section laid beside the original; link and pitch compared. 8, 9 Will the batch match the approved sample? Trial rounds, measured values and mass-production checks. 9, 11 What is checked before shipment? Nine finishing checks and a final inspection of the belt. 2, 12 Will it arrive undamaged? Inner and outer packing, and the cases on arrival. 13, 14 How you can check: ask for the same photos and values for your own order before it ships.

Page 6. PROJECT 1 · YOUR INPUT We start from what is already on your line The buyer's concern: a new belt that does not fit the sprockets and drum already installed. What the buyer sent Photos of the existing sprockets, the original belt on a sprocket, and a sketch of the drum: 4,860 mm (191.34 in) across with a 940 mm (37.01 in) belt.

Page 8. PROJECT 1 · NEW BESIDE OLD The new section laid beside the original The buyer's concern: a link that looks the same but does not match the original pitch. What we did Made a trial section and laid it beside the buyer's original belt: links, rod pitch and side guards compared side by side. New section (dark blue) above the original sections (light blue) New links in line with the original links How you can check: send a short section of your old belt; we photograph the new section beside it before production.

Page 9. PROJECT 1 · TRIAL AND SAMPLE Three trial rounds, two sample inspections, then approval The buyer's concern: a sample that passes, then a batch that does not.
