Abstract
A method of fabricating an anti-fatigue mat employs a pre-formed gel cushioning member that includes opposed major surfaces. One of the opposed major surfaces of the gel cushioning member is heated and liquefied. A flexible support sheet is applied and bonded to the liquefied surface of the gel cushioning member. The remaining opposed surface of the gel cushioning member is then heated and liquefied. A flexible base sheet is applied and bonded to this liquefied surface of the gel cushioning member. The method may move one of the opposed surfaces of the gel cushioning member adjacent a heat source to liquefy a portion of the gel cushioning member passing by the heat source. A flexible sheet is dispensed or applied to the liquefied portion of the gel cushioning member as the liquefied portion passes by a flexible sheet dispenser.
