Abstract
A floor covering with a fiber pile which is anchored in a layer selected from the group consisting of a latex, polyvinyl chloride, and bitumen layer, and a substrate layer, includes a base plate. The base plate is provided with burls which project to one side in rows at a distance with attendant formation of cable channels. The base plate with the burls is constituted by a knitted or woven material which is coated with synthetic resin and hardened. Alternately the cable channels can be provided in a spacer of planar configuration which has burl-type projections on at least one planar side, and where the projections leave between them intermediate spaces which constitute the cable channels.
