WEB CONTACTLESS CONVEYING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent a point failure such as cissing generated to a coated face by arranging a large number of gas blowoff holes at gas blowoff boxes provided on the upper side with respect to a web conveying direction. SOLUTION: A web 1 is a support body with its upper face covered with polyethylene resin with gelatine-contained applied solution applied thereto. Gas blowoff boxes 2 are arranged on the lower side of the web 1. Gas such as air is blown off upward to the rear from the gas blowoff boxes 2 provided on the lower side of the web 1, and gas flows toward the rear of the gas blowoff boxes 2 along the upper faces of the gas blowoff boxes 2. Arrow marks show a web conveying direction. Blowoff air from faces opposed to the web 1 blows against the web 1 to contribute to cooling or drying of the applied solution or floating conveyance. It is therefore necessary to arrange a large number of gas blowoff holes almost uniformly over the whole surface of at least the web opposed face of each gas blowoff box 3. Gas supplied into each gas blowoff box 3 by a fan is blown off through the gas blowoff holes.
