| Reel / Bobbin diameter range | e.g. reels of diameter up to ≈ 630 mm (or slightly larger), depending on model. |
| Reel (bobbin) width (coil width) | Typical bobbin widths for mid-size payoff: e.g. ~ 375–475 mm (for smaller reels) or somewhat larger depending on capacity. |
| Applicable wire / cable diameter range | Payoff should support the wire (or cable) diameter that will be unwound — depending on machine design. |
| Payoff / unwinding speed (line or take-up speed) | Up to certain metres per minute depending on reel size: e.g. some machines show a take-up speed up to ~ 100 m/min for certain reel-sizes. |
| Load / reel weight capacity (or loading capacity) | Capacity in terms of weight or load: for certain models ~ 2–6 tonnes depending on reel size / specification. |
| Tension control & regulation | A tension-control mechanism to ensure uniform unwind without over-tension or slack — essential for consistent feeding into downstream machines. |
| Bobbin clamping / chucking method (shaftless or with shaft / pintles) | Many payoffs use shaftless chuck for bobbins, or suitable pintles/clamps to hold reels securely during unwinding. |
| Traverse or coil-lay / winding/unwinding geometry (if applicable) | If the payoff has traverse or guiding to evenly unwind coil or guide cable, that’s a parameter. |
