TLDR
A strike-off device is a paving screed having a main screed and a screed extension attached to it as mentioned in this paper, where the plate has a generally horizontal working edge extending laterally along the front vertical surface of the screed.Abstract:
A strike-off device is for a paving screed having a main screed and a screed extension attached to the main screed, the screed extension having a generally vertical front surface. The strike-off device includes a plate disposed frontwardly of and adjacent to the screed extension. The plate has a generally horizontal working edge extending laterally along the front vertical surface of the screed extension. Two connective members extend between the strike-off plate and the screed extension and are configured to adjustably attach the plate to the screed extension, such that vertical displacement of the connective members adjusts a vertical position of the strike-off working edge. Preferably, the connective members are each a threaded rod having a first end engaged with the strike-off plate and a second end engaged with the screed extension, such that rotation of the rods displace the strike-off plate in vertical directions.read more
