Abstract

An improved corner bending apparatus and method for a bent head exchanger includes a first step of providing a tube edge clearance to at least the inner core face edges of those few tubes encompassed by the area of the core to be bent. A series of elongated braces, able to flex relative to one another, is placed into the tube edge clearance prior to bending. The braces actively maintain the tube edges (and tubes) in a parallel, undeformed orientation during the bend, which may be done by otherwise conventional apparatus.
