摘要： To effectively seal the atmosphere within a chamber against ambient atmosphere, particularly for drying or curing of printing ink by UV radiation, vacuum drying, or the like, a pair of plates (12, 13; 33, 34) are positioned contiguous with a pass-through slit formed in a side wall (6) of the chamber, the plates being formed with recesses, grooves or depressions (7-11; 29) extending transversely to movement of the paper web. Ambient air is conducted at the lateral sides to the recesses or grooves which, preferably, in cross section are circular and formed as semicircular grooves in the respective plates, and suction is applied essentially centrally, with respect to the width of the web (2, 40) by suction pumps (19, 23) which may apply an increading degree of vacuum to the recesses as the wall (6) of the chamber is approached. The width of the ridges adjacent the grooves or recesses can be determined by replaceable strips (35', 36') or by eccentric rollers (34, 35) so that the width of the pass-through slit between the plates can be matched to the thickness of the paper web (2, 40).
