Abstract
A machine to insert strips in expansion joints and concrete surfaces has features to prevent placing the strip in the joint while stretched. The machine includes the frame mounted on wheels. A supply reel mounted to the frame has a quantity of the strip wound about it. An insertion disk is rotatably mounted to the frame and positioned in the groove to push the strip into the groove. A pair of driven pinch rollers pull the strip from the roller. The drive mechanism for the rollers rotates the rollers at a speed selected to eliminate any tension in the strip between the insertion disk and pinch rollers.
