    Abstract: To form carpet tiles that lie flat, a layer of thermoplastic material is doctored onto a carrier sheet and a piece of carpeting to be coated is laid on the layer. The carpet piece has dimensions slightly larger than the desired carpet tile. Heat is applied to the layer to bond the layer of thermoplastic material to the carpet piece and the bonded layer and carpet piece are cooled so as to form a coated carpet piece. The carrier sheet is then stripped from the coated carpet piece and waste is trimmed from the periphery of the bonded carpet piece so as to form a carpet tile. The carrier sheet is supported on a substantially flat surface during the heating and cooling steps so that the carpet piece is maintained in a substantially flat and relaxed condition and the warps and wefts of the carpet piece do not support the weight of the carpet piece.
