Abstract
The method of appliqueing sheet material, in particular, bonding a synthetic resin such as polyvinyl chloride to one or more portions of a woven fabric, comprising supporting the synthetic resin applique in compressive engagement with the sheet material in a high frequency field at a temperature such as to cause fusing and bonding of the applique to the sheet material and while fusing the synthetic resin of the applique conducting vapors generated within the sheet material by said high frequency heating away from the sheet material to allow the use of a level of power to cause the synthetic resin to penetrate into the sheet material and to prevent condensation of the vapors on the platens of the high frequency press employed to effect bonding.
