Processing machine with contactless dusting system used in printing and coating process, has nozzles that blow air jets towards printing guide surface in advancing direction and at an angle with respect to printing guide surface

摘要

The machine has a contactless dusting system (5) arranged in a gap (4) formed between two cylinders (1,3). The dusting system has nozzles that blow air jets (20) towards the printing guide surface (8) of one cylinder (1) in advancing direction (6). The nozzles are arranged to blow air jets at an angle with respect to the printing guide surface. The nozzles are arranged within the air blowing channels (12,13) of the dusting system. The dusting system also includes an extraction channel (11) through which the blown off particles from the printing guide surface are discharged.
