Abstract: Systems and methods for pre-tensioning backing materials of a tufted product. The systems can include at least first and second tensioning assemblies and a guide assembly. Each tensioning assembly can have a backing supply subassembly for supporting a backing material and a roller subassembly for effecting movement of the backing material at a desired tension. The roller subassembly can include a driven roller for pulling the backing material from the backing supply subassembly, and a compensator for receiving the backing material from the driven roller. The guide assembly can simultaneously receive the tensioned backing materials from the tensioning assemblies and position the backing materials in contact with each other for delivery to a tufting machine at the desired tension.
