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.
A carpet tile assembly for application over and engagement with a base layer, said tile assembly comprising a tile member having an upper traffic-bearing layer integrally engaged with a substrate, a second layer of elastomeric material integrally bonded to said substrate, said second layer having a plurality of protrusions extending radially downwardly therefrom throughout the surface area thereof and a base layer having an upper surface including means for engaging said protrusions for resisting lateral movement of said tiles applied thereon.
A method for producing a carpet tile assembly comprising the steps of:
A carpet tile assembly for application over a surface comprising a base layer for receiving said tile assembly and a tile member having an upper layer of carpet material for forming a walking surface, a substrate layer for receiving and holding said carpet material, a second layer of resilient material integrally joined to said substrate, and said second layer having a plurality of protrusions extending radially therefrom and disposed substantially throughout the surface area of said second layer for engaging said base layer and resisting lateral movement of said tiles.
