Abstract:
A method of making a floor mat, the method comprising:positioning a thermoplastic layer on a mold having a plurality of cavities for forming projections on the thermoplastic layer;positioning a cover layer over the thermoplastic layer;forcing the cover layer and the thermoplastic layer against the mold to bond the thermoplastic layer and the cover layer together and to form a plurality of projections on the thermoplastic layer, each of the projections having an elongated body portion;positioning the thermoplastic layer and the cover layer between first and second platens of a press with the projections in heat transfer relationship with a heated surface of the second platen;allowing heat from the heated surface to sufficiently soften the projections;compressing the cover layer and the thermoplastic layer between the first and second platens so as form enlarged tips on the projections; andpositioning the cover layer and the thermoplastic layer adjacent a relatively cooler surface with the projections in heat transfer relationship with the relatively cooler surface to sufficiently solidify the projections.
