AIR-DISPENSING WEB-FLOATING APPARATUS

摘要

Apparatus including a plurality of pressure pads arranged in two series thereof at opposite sides of a web path and constructed with openings for discharging a gaseous medium against opposite sides of a web advanced along the path. The openings are of types and sizes which enable the two series of pressure pads to dispense the gaseous medium in a manner which achieves good heat transfer but avoids substantial variation in velocity and pressure as measured transversely of the web path in the impringement of a gaseous medium on the web.
