Method of manufacturing carpet for automobiles having a three-dimensional shape

摘要

A method for manufacturing a carpet used for an automobile comprises steps of: coating a preheated liquid foamable mixture directly on a back surface of the surface material by a spray system; placing the surface material in a molding die comprising an upper portion and a lower portion, the upper and lower portions defining a space inside the die corresponding to a three dimensional shape of the carpet; clamping the liquid foamable mixture with the surface material between those portions of the molding die, when the liquid foamable mixture coated on the back surface of the surface material has completed a gas reaction thereof but is still in a visco-elastic flowing condition; and changing the liquid foamable mixture into a solid condition, thereby a foamed body layer made of the liquid foamable mixture is molded in three dimension and is connected with the surface material through the back surface thereof.
