  • Patent number: 5553777
    Abstract: A method to form a new tie from used railroad ties includes the steps of removing metal from the used ties, planing three sides of each of the used ties, cross-cutting both ends of the ties, rip-sawing the ties into 1 to 2.33-inch strips, cross-cutting the strips to 18-96 inches. The method further includes rip cutting the resulting pieces into suitable sizes for gluing having complementary widths, roll coating the pieces with a coupling agent, applying adhesives and assembling the pieces into a beam. The beam is held in a clamp while allowing the adhesive to cure in room temperature and then is cross cut into proper length ties. The new ties are allowed to cure for another seven days prior to creosote treatment.
