Thermal Transfer
Heated metal surfaces remove moisture from wet fabric as it rotates against a convex exterior. The palmer drying cylinder operates as a finishing unit within textile plants to produce dimensional stability in linens. Steam pressure inside the unit maintains an exact temperature for removing internal water content from flax materials.
Precise contact time between the fabric and the hot surface dictates the final moisture regain level recorded in mill production logs.
Finishing Mechanism
Tension control systems regulate how the material moves around the curved face of the palmer drying cylinder. Rollers apply force to ensure the cloth maintains smooth contact against the cylinder surface without wrinkles or structural distortion. Excess heat leads to fibre degradation while low temperatures fail to eliminate moisture before the fabric moves to the inspection area.
Engineers calculate the required surface speed based on the density of the linen and the humidity level of the factory room.
Operational Boundary
Performance limitations arise when fabric width exceeds the effective heated area of the machine. Operators monitor the heat transfer rate because uneven surface wear reduces the drying efficiency across the length of the linen bolts. Output quality drops when foreign residue accumulates on the metal, requiring cleaning protocols to prevent spotting on the finished cloth.
Stable performance depends on the internal distribution of thermal energy reaching the exterior shell uniformly.
