Abstract
An apparatus for heating of thermally deformable sheet material includes a frame consisting of a pair of end beams extending laterally and a pair of side rails secured longitudinally between the end beams in a rectangular arrangement The side rail channels are oriented with their longitudinal openings extending upwardly. A heating tray assembly extends laterally and includes a pair of quick-release cam clamps disposed at opposed ends thereof to engage the respective side rail in a slidable, releasable fashion, so that the tray may be installed/removed at any location and clamped at that location. A sheet support assembly includes similar cam clamps at each end, and may be installed/removed at any location and translated/clamped at that location to maintain planar support of a workpiece.
