Infrared drier installation for passing web
First Claim
1. 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, andsaid 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.

Abstract
Infrared drier installation (1) for a passing web (2), which installation ( ) has gas-heated infrared radiant elements (5), arranged one next to the other so as to form a unit (4). Each unit comprises at least two adjacent rows (8) of gas-heated infrared radiant elements (5) stretching out in he transversal′(9) direction of the web (2) substantially over the entire with of the web (2). The infrared drier installation comprises means to recycle, at least partially, the said combustion gases. The drier installation as subject of the present invention is characterized in that the infrared drier comprises means (16) to avoid the suction of cold air between two adjacent rows of radiant elements (5).
