Abstract

585,870. Compound fabrics. BILHUBER, P. H. May 4, 1944, No. 8429. Convention date, July 30, 1943. [Class 140] [Also in Groups V, XI and XXIII] Mouldable material 10, such as wood veneers coated with thermosetting or thermoplastic resin, is pressed on to a former 12 by means of a fluidpressure rubber bag 27 and heated electrostatically by electrodes 16, 17, made of fine mesh copper screen. The electrode 16 is disposed between the bag and a blanket 15 of canvas which overlies the material 10. The blanket prevents embedding of the electrode 16 in the material 10. The electrode 17 is disposed between the (wooden) former 12 and a wooden core 19. Stringers 14, of adhesived veneer, which may be preformed or built up in situ, are disposed in grooves 13 in the former 12, and during moulding are united to the material 10. A burned-out fluorescent lamp mounted on the casing 23 glows when an electrostatic field is present.
