Abstract
A heat sealing bar assembly is disclosed that is intended to avoid distortion of the heat sealing edge due to thermal expansion of the heated sealing bar with respect to the unheated support beam to which it is mounted. The mounting means include a fixed center support, end supports that permit axial sliding of the ends of the heated seal bar with respect to the support beam, and a series of jacking screws between the center support and the end support for adjusting the shape of the heated sealing bar.
