METHOD FOR PRODUCING AN UNBACKED TENSION FLOOR Abstract of the Disclosure An unbacked decorative thermoplastic vinyl resin containing surface covering having a self-induced tension is manufactured by (1) fusing a vinyl resin composition decorative layer and a vinyl resin composition backing layer to a strippable dimensionally stable backing to form a fused thermoplastic decorative surface covering, and (2) removing the strippable backing and rolling the surface covering, thus placing the surface covering under tension and thereby elongating the outward racing layer and compressing the other layer. The composition and structure of the outward racing layer is such that, on unrolling the surface covering, the elongated layer overcomes the compressed layer and the surface covering is stretched to a dimension greater than its original unrolled dimension. On securing the surface covering at its periphery only, the tendency of the surface covering to return to its original dimension, i.e. its elastic memory, creates a self-induced tension therein.
