Smoothing device for flat printing materials |
摘要 |
A smoothing device includes guide surface sections for a flat printing material whose leading edge is pulled in a direction of travel over the guide surface sections. The guide surface sections have openings which communicate with throttling ducts that are pressurized with compressed air during operation. The guide surface sections form a smoothing notch and have air passage openings which communicate with a flow duct. The air passage openings are configured to cause pressure conditions when there is an air throughflow during operation such that the flat printing material forms a bead projecting into the smoothing notch.
