Abstract:
An infection resistant mat made by a process comprising:placing a first piece of cover material of a first color on a metallic nest, said first piece of cover material having peripheral edges;placing a segment of padding material on said first section of cover material at a predetermined position corresponding to a segment;placing a second piece of cover material having a second color over said padding material, said second piece of cover material having peripheral edges so that the peripheral edges of said second piece of cover material are in contact with said peripheral edges of said first piece of cover material;applying a platen against said second piece of cover material;applying radio frequency energy through said platen to seal said peripheral edges of said second piece of cover material to said peripheral edges of said first piece of cover material with said segment of padding in between, thereby creating a contiguous sealed seam having no portals of entry for bacteria, vermin or fluids; andapplying radio frequency energy to said first and second cover materials in a pattern adjacent the predetermined segment whereby a seal is formed adjacent the segment, the seal having at least one airflow channel formed therein.
