Abstract
A method and apparatus for automatically attaching end plates to the ends of a railroad tie. A web of material automatically is fed to a plate assembly position. A portion of the web of material is formed into an end plate at the plate assembly position. The formed end plate is removed from the web of material. The formed end plate then automatically is connected to one end of the railroad tie. The system also senses the size of the end of the railroad tie and the end plate formed at the plate assembly position automatically is sized to be about the same size as the sensed size of the end of the railroad tie.
