Abstract

987,724. Moulding lampshades. WARD & GOLDSTONE Ltd. March 18, 1964 [April 3, 1963], No. 13131/63. Heading B5A. A lampshade is formed from a pleated tubular blank 16 of a thermoplastic material, e.g. stiff polyvinylchloride, by placing the blank over a hollow stem 5, between a fixed concave former 9 and a slidable concave former 10, heating the blank, and then moving member 10 towards member 9 to force the heat softened blank outwards into contact with the formers as in Fig. 3. The blank is heated by immersing the assembly in a heated liquid bath, the hot liquid contacting the blank through holes 8 in the stem and holes 11 in the formers. Former 10 may be manually moved towards former 9 by a handle 14 or may be drawn towards it by a spring located between the end hub 7 of the stem 5 and the member 10.
