Abstract

1,011,589. Seaming non-metallic sheet material. FISHER & LUDLOW Ltd. Feb. 5, 1964 [March 16, 1963], No. 10507/63. Heading B5K. [Also in Division H5] Dielectric welding apparatus, e.g. for producing P.V.C. vehicle seat covers, comprises an upper conductor plate (not shown), a lower conductor plate 10, and an intermediate array of conducting bars 16 in a frame 11 hingedly connected to the lower plate. The upper and lower plates are connected to the electricity supply, while the bars are insulated therefrom and from each other. Each hinge 19, 20 includes a link 17, 18 to enable the frame 11 to remain parallel to the conductor plates when it is sandwiched between the sheets to be welded. The arrangement produces a left and right pair of covers at each operation. For loading, the free end of the frame is raised by a handle 27 acting through support arms 23, 24 on projecting lugs 21, 22; a spring link mechanism retains it in the raised position (Fig. 4, not shown) until manually released by the use of both hands. The work sheets are positioned by abutments 30 on the lower plate and by spring fingers 31 on the frame which are depressed by the top plate. The frame is of resilient construction as described in Specification 1,011,589.
