Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
198 words
The method of bonding an applique of thermoplastic synthetic resin to a permeable substrate of woven material comprising depositing the applique to be applied to the woven material in the cavity of a silicone rubber mold containing a cavity corresponding in configuration to the applique, superimposing upon the surface of the mold across the cavity therein and in engagement with the applique situated in the cavity, the woven material, a porous release sheet, and an open cell absorbent sheet, placing the assembly comprising the mold containing the applique, the woven sheet, the release sheet, and the absorbent sheet between the platens of a high frequency press and while maintaining the platens at a temperature below the fusion temperature of the synthetic resin of the applique, applying pressure to the assembly and simultaneously subjecting the assembly to high frequency heating at a pressure level such as to fuse the synthetic resin, drive such vapors as are generated in the woven material through the release sheet and induce penetration of the fused synthetic resin into the woven material and while subjecting the assembly to heating between the platens, trapping the generated vapors penetrating the release sheet within the absorbent sheet.
