Claim:
A non-contact infrared drier installation for a passing web, comprising: gas-heated infrared radiant elements arranged next to one another so as to form a unit, wherein the installation heats the web without contacting the web with a heated surface, and said unit comprising at least two adjacent rows of gas-heated infrared radiant elements stretching out in a transversal direction of the web substantially over an entire width of the web, wherein said infrared drier installation comprises a recycling device recycling, at least partially, combustion gases, wherein said infrared drier installation comprises a device preventing suction of cold air between two adjacent rows of radiant elements in said unit, wherein the device preventing suction of cold air between two adjacent rows of radiant elements fills a space between the two adjacent rows of radiant elements in said unit such that a device preventing suction of cold air is located between each and every element in said unit, wherein the device preventing suction of cold air physically blocks a flow of air between the two adjacent rows of radiant elements.
