CA 1341056

A process for molding upholstered chair cushions comprising placing a sheet of upholstery fabric between two dies, one having sculptured effects thereon, the dies being movable toward each other to form a cavity between them. A cushion assembly having a thickness (with the upholstery) greater than the distances between the dies in the cavity placed in the cavity after having been coated on at least one side adjacent the upholstery with an air permeable adhesive. The dies are urged together to compress the cushion in the cavity to force the fabric and the cushion to conform to the shape of the first die. Hot vapors are injected into the cavity to shape the cushion and the fabric generally to the sculpted configuration of the sculpted die.
