Super Air Knife Cools Thermal Printer Nip Rolls

This customer operates a thermal printer, and was having problems with the nip rolls getting hot from contact with the printed sheet. The rolls are wider than the sheet, so the exposed surfaces of the rolls did not get as warm as the surfaces that come into contact with the rolls. The uneven dispersion of heat caused an uneven expansion of the roll, causing the sheet to lose registry. Using a Model 110048 48" (1219mm) Super Air Knife to provide cooling air, they were able to control and moderate the temperature of the roll and maintain registry of the printed material.
