A method and apparatus for securing an enlarged sheet-like fabric to a side face of a panel which is provided with edge frame elements having retaining channels extending therealong. Each retaining channel has a film or bead of a solid adhesive therein. An edge portion of the fabric is positioned to extend over the mouth of the groove, and is then folded over an inserting member which inserts the fabric edge portion into the groove. Substantially simultaneously the adhesive film or bead is heated, as by an induction heater, and the inserting member presses the folded fabric edge portion into the melted adhesive. This contact is maintained and the adhesive is subjected to cooling to effect resolidification thereof and fixed securement of the inserted fabric portion to the channel part. The insertion preferably involves an inserting device having a plurality of blade-like rollers which insert the fabric into the channel as the edge frame of the panel relatively moves longitudinally along the set of rollers.

A method for securing a flexible sheet fabric to an enlarged side face of a panel member, comprising the steps of: providing an enlarged panel member having an enlarged and approximately planar side face, said panel member having opposite and generally parallel side edges defined by generally parallel and elongate edge members reach having an elongate and outwardly opening retaining channel extending longitudinally thereof; providing an elongate strip of a solid but meltable adhesive within each of said retaining channels; providing an enlarged sheet of flexible fabric having a width greater than the width of said side face as defined between the opposite edge members; positioning said fabric so that the fabric is stretched over but free of fixed securement to said side face with opposite edge portions of said fabric extending over the retaining channels; positioning a fabric-inserting member adjacent the retaining channel; moving the fabric-inserting member into the retaining channel to cause the fabric-inserting member to engage the edge portion of the fabric and to insert the fabric into the retaining channel; heating the adhesive in the retaining channel to cause the adhesive to melt and contact solely the fabric as inserted into the retaining channel; and cooling the adhesive within the retaining channel to effect resolidification thereof and fixed securement of the adhesive to both the fabric and the retaining channel of the edge member while maintaining the fabric free of fixed securement to the side face of the panel.
