Abstract: A carpet tile assembly which resists lateral movement and a process of producing the same are disclosed, the carpet tiles having a tufted carpet layer or similar surface and a second layer of elastomeric material vulcanized to the carpet layer. The second layer has a plurality of protrusions formed therein and a plurality of spikes on the protrusions which together engage a base layer which may be either a mirror image of the second layer or a needle-punched or felt-like fiber mat to resist lateral movement of the applied tiles. The process involves tufting carpet yarn into a substrate and then vulcanizing the second, elastomeric or resilient layer to the substrate. In the vulcanization process, heat and pressure are applied to soften the elastomeric material and force the material through cavities in a perforated sheet to form the protrusions.
