Patent ID: 6983696

Claim:
An apparatus for cooling sheets to be printed and printing machine elements at a sheet-fed printing machine by means of cooled compressed air, said sheet-fed printing machine comprising: at least one transfer drum, at least one printing cylinder; a delivery area; and at least one dryer; said apparatus being an integrated pneumatic sheet-guiding and cooling assembly comprising: at least one pneumatic sheet-guiding device, disposed in an effective range of said at least one dryer and along a sheet-guiding path, for pneumatically guiding the sheets to be printed along the sheet-guiding path, said at least one pneumatic sheet-guiding device being equipped with a device for supplying fresh compressed air for pneumatic sheet-guiding, and being located in immediate vicinity of said sheet-guiding path, at least one cooling device assigned to said device for supplying fresh compressed air, located in said integrated pneumatic sheet-guiding and cooling assembly for cooling a compressed air stream for pneumatic sheet-guiding, wherein said at least one cooling device is constructed as cooling surfaces in a cross section of said compressed air stream of said device for supplying fresh compressed air, and said cooling surfaces are constructed as a cooling register with lamellar air-guiding elements in a flow direction, through which a coolant flows.
