ABSTRACT:
Apparatus for floatingly suspending a running web without contact and through an arcuate path and including a series of parallel air bars arranged in an arcuate array for discharging pressurized air outwardly therefrom. Either the first or the last air bars, or both air bars, (in respect to the direction of web travel) may be tilted about their longitudinal axis to correct any non-symmetrical web-to-air bar orientation and to provide more stable pressure profile for the air cushion in a symmetrical web flow pattern. A line of equipment for processing a running web and including (1) a preliminary web treating machine from which the web exits selectively at two different locations and thus at two different angles; (2) apparatus for floatingly suspending the running web through an arcuate path; and (3) a floater dryer located at the discharge end of the turning apparatus; thus, the arcutate array of air bars can accommodate different web paths as the web exits from the web treating machine.
