Abstract
An edger assembly is for a paving vehicle screed for forming a paving material mat upon a base surface. The edger assembly includes a support connectable with the screed and an edger member having a contact surface contactable with the base surface. An actuator has an upper end coupled with the edger member and a lower end coupled with the support, the upper end being displaceable with respect to the lower end to vertically displace the edger member relative to the base surface. The actuator preferably includes two threaded blocks coupled with the support and two rotatable rods each coupled with the edger member and engaged with one block. Rotation of the rods vertically displaces the rods with respect to the support to displace the edger member. Preferably, a biasing member is disposed about each rod and biases the edger member in a direction generally toward the base surface.
