Machine Maintenance
Under-dose and the chain seizes in the rail. Over-dose and it drips on the cloth. Past a certain oven temperature, no dose avoids both.

Total dose needed to replace what the oven takes
A negative drip margin does not mean the chain will be starved — it means the dose required to keep it lubricated is itself high enough to contaminate the fabric, and the answer is a higher-temperature oil or a different lubrication strategy rather than a different dose. Both the Q10 factor and the drip threshold are plant-specific and must be established from oil consumption logs and staining incidents on the actual machine; a synthetic high-temperature chain oil has a quite different Q10 from a mineral one. The chain also sees its highest temperature in the hottest zone rather than the average, and it is that zone which governs.
