The invention provides a cushioned frame for a picture or other article, which has a bottom layer with edges, a relatively rigid base with first and second sides, a layer of foam material secured to the base by adhesive stripes and having the configuration the size of the base, an upper layer of material sealed along its edge portions to edges of the bottom layer to enclose the foam layer, a transparent or translucent layer over the upper layer and adapted to fit in the section defined by the adhesive stripes, this layer being secured to the upper layer by depressed heat-seal stripes and cooperating therewith to define an envelope for a generally planar article, the foam layer being compressed at the stripes which bond the transparent or translucent layer, the upper layer and the foam material layer. The apparatus includes an adhesive applicator machine having a vat, a supporting frame slidable on guide rails above the vat, to receive bases, articulated arms for moving an adhesive printing assembly into the vat and into engagement with the bases, and an actuator for the arms. A locating device for accurate positioning of layers, a dielectric sealing device, and a die-cutting apparatus, are utilized.
