Abstract
A method and apparatus for bending a heat exchanger coil, and particularly a fin-on-tube coil, is provided which reduce pressure on the coil at a bending location to prevent damage to the fins and coil by effecting relative movement between a support bed for the coil, defining a coil plane, and a rotating mandrel, in a direction perpendicular to the coil plane during approximately the first 10.degree. of rotation of the mandrel. Such relative movement can be accomplished by either moving the support bed or by moving the rotational axis of the mandrel.
