METHOD AND APPARATUS FOR PRODUCING CARPETED PANELS

摘要

Carpeted panels comprising a thermoplastic substrate and a synthetic fiber carpet are produced by bonding the respective parts to one another using a vibration welding apparatus for causing the generation of frictional heat at the interfacebetween the substrate and the carpet. One of the platen of the welding apparatusconfronting the carpet is provided with a pattern of closely spaced pins engaging the carpet and urging the carpet into forced engagement with the substrate. On account of the closely spaced pins and the relatively low amplitude of the reciprocatingmotion, a bond is achieved substantially over the entire interface between the carpet and the substrate.
