A method for reducing the required cooling capacity in a cooling roller support of a web-fed rotary printing press and a device in a cooling roller support with chill rolls

摘要

A method for reducing the required cooling capacity in a cooling roller support (06) of a web-fed rotary printing press, wherein one or more in the cooling roller support (06) incoming material webs (01) before the impact on a first cooling cylinder (07 - i) is acted on with an air flow, of the running direction of the material web (01) is in the opposite direction and extend over the entire width of the web of material (01), wherein the stream of air under an afflux angle (β) of 15° to 60° to the web of material (01), wherein the flow velocity of the air stream 0,2 to 2 m / s, and wherein the stream of air under a pressure of 3 to 10 bar to the web of material (01) is deflected, so that the ‘ coanda "- effect is utilized.
