Abstract
A heating element hold-down assembly having a heating element adapted to be removably mounted on the screed and a hold-down mechanism adapted to be removably mounted on the screed. The hold-down mechanism comprises a hold-down mechanism frame adapted to contact the heating element, a resilient device adapted to move between an expanded position and a contracted position, a tension shaft, a portion of which is adapted to contact the resilient device, a pin adapted to removably attach the tension shaft to the hold-down mechanism frame, and an adjustment means adapted to be adjustably connected to the screed frame so as to contact the tension shaft. The hold-down mechanism is adapted to maintain contact between the heating element and the screed plate when the screed moves, flexes, or is adjusted.
