Abstract
841,996. Bonding by dielectric heating. RADIO HEATERS Ltd. Jan. 25, 1957 [Nov. 7, 1955], No. 31791/55. Class 39(3). [Also in Group VIII] In the formation of an upholstered panel using radio frequency dielectric heating to bond two sheets of material forming the sides of the panel, pressure is applied to selected portions of the panel to compress them in sequence progressively over the area of the panels, the portions then being bonded while they are under pressure. Undue strain in the material forming the sides of the panel is thus avoided. As shown in Fig. 3, electrodes 14a-14e are lowered in sequence to compress portions of material 8 and 12, the cover material 8 moving from right to left over wadding 10 without undue stretching. Welding power is then applied between the electrodes 14 and the common electrode 18 and bonding takes place. The backing material 12 of the panel so formed remains approximately flat and a pronounced quilting effect is produced on the upper surface of the panel. Unnecessary compression of the wadding layer may be reduced by loading bars 36, Fig. 6, which consist of a series of rods or strips, and are inserted under the cover material before the bonding operation. Withdrawal of the bars after the fluting welds have been completed results in a maximum formed shape of the cover 8 and a deep upholstered appearance of the panel. The cover material and backing material may be thermoplastic sheeting, e.g. P.V.C., which may be either unsupported or supported on an open-weave backing cloth. The wadding may consist of felt, cellulose, paper, sponge rubber, foamed vinyl, polyurethane foam, or synthetic fibre ; coatings or sheets of glues or resins may be used to promote the bond between the cover and backing. Pneumatic rams or a series of cams may operate the movable electrodes which may be given a shape corresponding to the form of the indentations required.
